Route 305 was never legislatively defined. However, there is a portion of a route that is known to AASHTO as I-305 for funding purposes. This segment, from the Route I-80/US50 interchange in West Sacramento to the Route 99/US50 interchange was originally part of I-80. It was redesignated as chargeable I-305 in May 1980 (and that designation remains on the books at AASHTO). Later in 1980, it was reassigned to US 50. It is currently signed as US50/Business Route 80 from the jct with Route 99/US50/Business Route 80 on east side of Sacramento to the jct. with I-80.

Note: Although I-305 is signed as US 50, itis still on the books as Federal-Aid Interstate 305. The FHWA log shows it as 8 miles.

Status Status

In December 2010, major storms resulted in the washout of a section of Route 330 at the Postmile 35, just about 6 miles north of Highland Avenue. Repairs were estimated to be finished in late 2011 or early 2012. Work will be divvied up into three phases across the approximately 15-mile highway. The $6 million first phase to fix several smaller washouts and prepare the roadway will allow larger equipment to reach the worst-hit area.

In March 2011, it was reported that the road was reopened for commuter traffic only. Drivers will be able to drive downbound between Live Oak Road and Highland Ave in the morning between 6am and 8am. In the afternoon and evening, they will be able to drive upbound from Highland to Live Oak between 4 and 6. Traffic will only be one direction during commute times and motorists will need to use the proper lane. CHP says that they may close the road at anytime if there’s bad weather or reckless driving that endangers the safety of the construction workers.

In June 2011, it was reported that Caltrans now is targeting the full reopening for the July 4th holiday weekend.

Naming Naming

Route 330 in the County of San Bernardino is named the "Steve Faris Memorial Highway" This route was named in memory of Battalion Chief Steve Faris of the California Department of Forestry and Fire Protection. In 1998, Battalion Chief Faris helped establish in the Inland Empire the Mountain Rim Fire Safe Council, which was the first of more than 14 councils that are now active in the Counties of San Bernardino and Riverside. He was instrumental in bringing together the fire safe councils to form the Inland Empire Fire Safe Alliance. In 2002, Battalion Chief Faris was intimately involved in the establishment of the Mountain Area Safety Taskforce (MAST), which brought local, state, and federal agencies together to address the critical fire situation presented by the bark beetle-drought tree mortality issues. The consolidated efforts of MAST and fire safe councils contributed significantly to the safe evacuation of more than 60,000 people during the Old Fire of 2003. Battalion Chief Faris was a friendly, giving, and passionate person who included everyone and found a way to work with anyone interested in his efforts to save lives and establish defensible space for properties in the mountains. Battalion Chief Faris died in an automobile accident in September 2006. Named by Senate Concurrent Resolution (SCR) 12, Resolution Chapter 72, on 7/14/2009.

State Route 371

Routing Routing

Rte 371From Route 79 near Aguanga to Route 74 east of Anza.

Post 1964 Signage History Post 1964 Signage History

In 1974, Chapter 537 defined Route 371 via a transfer from Route 71: "Route 79 near Aguanga to Route 74 east of Anza." It runs along Cahuilla Road.

With respect to the transfer of Route 71 to Route 79 from County Sign Route R3 to Temecula and the creation of Route 371, Scott Parker on AARoads noted: The adoption of Route 79 along Winchester Road threw the area's highway network into chaos -- and this was before I-15 (and I-215) were even on the scene. The Division of Highways had recently brought the connector from Route 79 near Aguanga northeast to Route 74 (i.e., originally part of Route 71, now Route 371) into the state system as a "shortcut" from the San Diego area to Coachella Valley cities. Without it, Route 71 would have simply been truncated to end at Murietta, north of Temecula (at the site of the present 15/215 split) -- but D8 chose to multiplex Route 71 and Route 79 together for about 20 miles total to Aguanga, where Route 71 struck out over the new route NE to Route 74 (which was a bit awkward, as Route 71 and Route 74 then intersected one another twice, at Elsinore and near Anza). This arrangement lasted all of 8 years; after it was decided to route I-15 down Route 71 from Corona south to Temecula. So, in 1974, D8 simply truncated Route 71 at the (then) US 395 junction in Murietta, leaving Route 79 as the sole occupant of the Temecula-Aguanga route; the Anza connector was redesignated as Route 371. This happened at the same time as the commissioning of Route 330 due to the reroute of CA 30 away from the San Bernardino mountains and over to Redlands -- so a 300-series number wasn't an isolated case. Of course, when I-15 was completed south of Corona, Route71 was cut back to its Corona-Pomona section, and US 395 was cut back to I-15 at Hesperia, with, first, I-15E and after 1982 I-215 taking over its routing. But today that relatively short (about 3 mile) section of I-15 multiplexed with CA 79 in Temecula is one of the most congested locations in the Inland Empire; and both adjacent sections of CA 79 itself -- relinquished or not -- are the two most heavily developed commercial "strips" in the area.

Rte 371 when it was Rte 71This was the eastern end of Route 71. It was LRN 277, defined in 1959. Note that Route 371 starts at Post Mile RIV R56.467, which is a vestage of its previous numbering as Route 71.

It appears that instead of building a new alignment for LRN 277 (as planned in the 1960 state highway map), the Division of Highways opted to assume maintenance of Cahuilla Road and Kenworthy-Bautista Road. LRN 277 can be seen aligned over Cahuilla Road and Kenworthy-Bautista Road on the 1962 Division of Highways State Map.

From the junction was LRN 78 (present-day Route 79), Route 71 continued to the W to Temecula, signed as Route 71. A short portion was cosigned as Route 71/Route 79 (the portion between the present-day Route 79/Route 371 junction and Riverside County Sign Route R3. Route 79 continued N along present-day Riverside County Sign Route R3, while Route 71 continued to the W. In 1966 (although historical information leads one to believe this happened in 1974), County Sign Route R3 was defined, and Route 79 continued cosigned with Route 71 all the way to US 395 (now I-15). In 1974, that segment was resigned as Route 79 only. Route 71 then turned N, continuing up what is now I-15 to Route 91. It was cosigned briefly with Route 91 to Corona, and then continued N to Pomona. This latter segment is all that remains of Route 71.

Left Turn Lane Project

The intersection of Route 371 and Route 79 (RIV R56.517) has demonstrated itself to be a high source of accidents, with four deaths occuring in the period from July 2001 to July 2002. As a result, the intersection is being redesigned. Two-lane Route 79 is the main link between Temecula and the Warner Springs and Santa Ysabel areas of San Diego County. Two-lane Route 371 is a well-traveled back road between Southwest County and Palm Springs. Currently, the two roads converge in Aguanga where an oddly configured intersection contributes greatly to the accident count. Westbound traffic on Route 79 must stop at the intersection, while eastbound traffic on Route 79 and traffic coming down a steep curvy grade from Anza on Route 371 proceed without stopping. Beginning in Summer 2003, work started to reconfigure the intersection to force drivers heading toward Temecula to stop and turn either left of right at a "T" intersection with Route 371. Turning left would take them quickly back to Route 79. Long-term improvements will include a merger lane from Route 371 to Route 79. As of April 2008, construction had been completed: It is now a standard T intersection with 3-way stop signs. Traffic leaving Route 371 is forced to turn, while travellers on Route 79 can proceed straight through. Most of Route 371 has been newly repaved as well. Most of the mile markers on Route 371 are very weathered (similar to the section of Route 74 between Route 371 and Route 111) but are marked with mileage between PM 57 (at the south end) and PM 78 (at the north end).

In July 2016, it was reported that Caltrans began construction on a left turn lane project on a section of Route 371, in the section of roadway along Route 371 two-tenths of one mile west of Bahrman Road and just west of Bailiff Road in the unincorporated community of Anza. The $520,000 project, which was awarded to All American Asphalt, is expected to end by the beginning of September 2016. All American Asphalt will begin clearing and grubbing on July 11, 2016 and is expected to continue until July 15. During clearing and grubbing, Caltrans workers focus on the preservation of public and private property and pay special attention to environmentally sensitive areas. The project will be constructing left turn lanes for both directions of travel on Route 371 and also be digging to allow access for underground utilities.

In October 2016, it was reported that Caltrans had resumed work to complete the Route 371 Left Turn Lane Project at Bahram Road that will include additional highway work requested by Anza residents in an Anza Valley Municipal Advisory Council meeting in July. The project scope had been altered to accommodate the extension of a two-way continuous left turn lane from the center of Anza to the intersections at Bahram rather than the originally planned left turn lanes at Bahram. Requests from the Anza community at a recent Municipal Advisory Council meeting led Caltrans to change the lane configuration based on the access needs of community and local businesses. The changes being requested by Anza residents required an additional $160,000 to be added to the original $520,000 project. The planning change by Caltrans was the second in the community with the first being a plan to cut some of the historic trees along Route 371 in the main village area. Plans were changed on the residents’ requests and updated engineering reports. The work was scheduled for completion at the end of 2016.

Route 371 Safety Improvements

In January 2017, it was reported that Caltrans had announced it will constructing rumble strips on the existing shoulder and centerline of Route 371 in Anza from Wilson Valley Road to Cary Road (~ RIV R56.517 to RIV 67.845) and from Kirby Road to Route 371/Route 74 (~ RIV 72.813 to RIV 76.958) starting in 2018. Rumble strips on highways are designed to let motorists know when they are drifting out or into the opposing lane or into the shoulder. “Caltrans is currently in the Preliminary Engineering phase, and we are developing the Environmental Document and the Project Report,” said a news release sent by Elaheh Hadipour, PE, Caltrans project manager. “The project is currently programmed to start construction in late 2018.”
(Source: Anza Valley Outlook, 1/26/2017)

In April 2017, Caltrans issued a bulletin noting that, starting May 14, 2018, they will be making safety improvements near Cahuilla in two locations on Route 371 between Route 74 and Route 79 to place centerline and shoulder rumble strips and install enhanced visibility 6-inch striping. The first location is from Wilson Valley Road to Cary Road (post mile 60.2 to post mile 67.7) and the second area is from Kirby Road to Route 74 (post mile 72.8 to 77.1.) The estimated $756 thousand project, awarded to Jabre Contracting Inc., is anticipated to last less than thirty working days.

Naming Naming

"Cahuilla" Road

The portion of Route 371 from Tribal Road to Howard Road (~ RIV 67.12 to RIV 68.717)near the community of Anza in Riverside County is officially named the "Special Deputy Frank Hamilton Memorial Highway". It was named in memory of Frank Hamilton, a Native American and a Cahuilla tribal member from the Anza area, who in 1895 was working as a Riverside County special deputy sheriff. Hamilton acted as a law enforcement officer for the Riverside County Sheriff’s Office in the areas surrounding the Cahuilla and Ramona Reservations (Anza) area, including the area surrounding the town of San Jacinto. Hamilton had family ties to both reservations. Hamilton, who was 34 years of age and unmarried, was the son of a prominent rancher, James Hamilton, namesake of the Hamilton School in the community of Anza. He resided at the family ranch, which was first in Cahuilla, now present day Anza. The ranch then moved to Kenworthy, presently known as Garner Valley. In the early years of Riverside County, special deputies were used throughout the county to support the operation of the Riverside County Sheriff’s Office. In the first few years of its existence, the Riverside County Sheriff’s Office consisted of one sheriff and two deputy sheriffs. Riverside County was incorporated on May 9, 1893. Special Deputy Frank Hamilton was the first deputy sheriff in Riverside County to be murdered in the line of duty and his killing was the subject of the first murder trial held in Riverside County’s history. On the evening of April 8, 1895, Special Deputy Frank Hamilton was in the town of San Jacinto tending to his duties as a special deputy sheriff. He was in the town saloon when a disagreement erupted between him and Charles Marshall, who had greeted Special Deputy Frank Hamilton with a racial epithet. Marshall became enraged over the disagreement and left. Special Deputy Frank Hamilton had told Marshall to go away and that he did not want any trouble with him, but Marshall retrieved a revolver and went in search of Special Deputy Frank Hamilton. Marshall located Special Deputy Frank Hamilton in an alleyway adjacent to the town saloon, and, without warning, began firing, hitting Special Deputy Frank Hamilton twice as he returned fire and managed to wound Marshall. Special Deputy Frank Hamilton succumbed to his gunshot wounds the following day, April 9, 1895. Named by Senate Concurrent Resolution 51, Resolution Chapter 2, on February 1, 2016.

    In 1969, Chapter 294 defined Route 380 via a transfer from Route 186 as “(a) Route 1 near Pacifica to Route 280 in San Bruno. (b) Route 280 in San Bruno to Route 101 in the vicinity of the San Francisco International Airport. (c) Route 101 in the vicinity of the San Francisco International Airport to Route 87.” This segment remains as defined in 1963. In 1970, Chapter 1473 deleted segment (c)

    This segment would have been signed Route 380, as it was never planned to be part of the Interstate system. It would have curled through the hills, crossed Route 1, and continued slightly west before curving south to meet Route 1 again. Terrain and seismic problems (the route would cross over the San Andreas Fault) are what killed this segment of freeway. There has been talk in times past of extending 380 to Skyline Blvd, but no serious proposal has come forth for that.

    Western End of Rte 380According to Chris Sampang, the Sneath Lane/San Bruno Avenue exit off of I-280 (both southbound and northbound) has several signs of the planned interchange to Route 380 west:

    1. Long ramps in both directions. The ramps to Route 380 would have fed off what currently functions as a collector/distributor between Sneath and San Bruno; the whole exit complex, which crosses under Route 380 on the northbound side, is about ½ to ¾ of a mile long north/south.

    2. On both sides, there is room on the exit sign for Sneath Lane/San Bruno Ave for a shield (it was once there covered in greenout; that appears to have been removed in a sign refresh). Also, advance guide signs off of I-280 north point out the I-380 exit, as underneath the 380 shield, is a protruding state shield (again, this appears to have been removed in a sign refresh).

    3. There is some grading of the planned Route 380 west of the interchange for about ¼ mile; however, there's barely any pavement as the road fades into the trees.

    4. The sign gantry for the Route 380 ramps westbound into I-280 is very wide; this is to cover both the ramps heading to 280 and the mainline carriageway that would've gone into Pacifica (although this is not-definitive, as this type of sign gantry is typically long).

    Through analysis of maps, Chris has identified a possible routing: I-380 would've continued west of the current Y interchange with I-280 first through a path between Claremont Drive and Crestmoor Drive headed to Skyline Boulevard (Route 35). Route 380 would've met near the San Bruno Avenue and Skyline Boulevard junction; most of the possible ROW is currently either forested or parkland. West of Route 35, Route 380 would've crossed the San Bruno City Limit and straddled it on the south side, following trails in the Golden Gate National Recreation Area in Sweeney Ridge as it entered Pacifica. It would follow some paved trails to the junction of Mori's Point Road, Bradford Way, and Route 1; this just also happens to be the current south end of the Route 1 freeway (and may imply that this south end of the Route 1 freeway was to have been directly connected into Route 380). Past Route 1, Route 380 would head southwest at a 20 degree angle or so away from Mori Point but towards the coast; at the coast, the freeway would make its southward turn back to Route 1. Another map that illustrates this quite well can be found here.

    The Caltrans "Naming" document indicates that this section is named the "Portola" Freeway. Gaspar de Portola was California's first Spanish governor. In 1769 marched north from San Diego in command of the first party of Europeans to see San Francisco Bay. This expedition also discovered the Golden Gate and Carquinez Straits. He founded the presidio at Monterey and aided in establishing Mission San Carlos. Named by Assembly Concurrent Resolution 113, Chapt. 217 in 1970.

    "Southern Crossing"

    1946 Southern CrossingAfter the construction of the Bay Bridge in 1933, San Francisco began considering duplicating the bridge and running a second one further south across the bay. Enter Frank Lloyd Wright, the famed organic architect whose idea and design for a second Bay Bridge never came to fruition. The noted architect hated the idea of a second steel structure similar to the San Francisco–Oakland Bay Bridge. Partnering with engineer Jaroslav J. Polivka, Wright proposed a concrete "Butterfly Bridge,” spanning from Army Street (now Cesar Chavez) and Third Street to its eastern terminus on Bay Farm Island, just north of the Oakland Airport. Wright and Polivka saw steel truss bridges as extravagant and obsolete, so the design was all reinforced concrete, resting on a series of giant hollow almond-shaped piers—which they claimed to be earthquake-proof construction. Long curved arms would carry six lanes of traffic and two pedestrian walkways, supported by two arches connected by a butterfly-shaped garden park (!) as “a pleasant relief and perhaps a stopping point for the traffic.” The Butterfly Bridge project lost steam after plans for the underwater—and vastly more important—Transbay Tube were unveiled, a project that connected BART from San Francisco to Oakland.
    (Source: Curbed SF, 12/8/2017)

    Rep. Richard J. Welch of San Francisco believed that another span was not only a good idea, but a necessity. The Chronicle’s May 1, 1946, edition reported that a joint Army-Navy board of engineers was brought in to respond to the controversy and rule on whether plans would proceed. Why an Army-Navy board? Army permission was needed before a navigable waterway could be bridged or dammed, and the Navy, with many installations in the Bay Area, had expressed opposition to another Bay Bridge. The recommendation was for a low-level, six-lane combination trestle and tube from the foot of Army Street in San Francisco to the foot of Fifth Street in Alameda. “Immediate” construction was urged. The next day’s Chronicle read: “Another bridge between San Francisco and the East Bay was assured yesterday.” The figure to the right shows the New Trans-Bay Bridge proposal, submitted by Kenneth B. Jones to the Army-Navy board, would exit San Francisco at Army Street and arrive in the East Bay just south of the Alameda Naval Air Station.
    (Source: SF Chronicle; 12/11/2017)

    [Southern Crossing]This map shows the proposed Southern Crossing. This would have been an additional crossing S of the Bay Bridge, terminating in Oakland (two approaches in Oakland: one along Alameda and one along Doolittle to the I-880/Hegenberger interchange). The history of the Southern Crossing goes back at least to 1948, when the state department of public works prepared a report on additional toll crossings of San Francisco Bay. This report noted "Because of the increasing congestion on the San Francisco-Oakland Bay Bridge, the California Toll Bridge Authority, on Oct 30, 1945, directed the Department of Public Works to make comprehensive studies for another bay crossing between SF and the East Bay cites. On Jan 31, 1947, the department recommended construction of an additional bridge just north of and parallel to the existing bridge—a plan which is now known as the Parallel Bridge." This report provided an estimated cost for the Parallel Bridge of $155,014, 000, and an estimate for the Southern Crossing of $178, 421, 000. The original concept of the Southern Crossing is illustrated to the right. There's an extensive discussion of the Southern Crossing and the Parallel Crossing in the November-December 1947 issue of California Highways and Public Works .

    In 1954, it was reported that the plan for the Southern Crossing had changed again. The western terminus would be in the vicinity of Third and Army in San Francisco, and the eastern terminus would be on Bay Farm Island in Alameda County. In 1954, the State Dept of Public Works applied to the Army Corps of Engineers for permission to construct the crossing. Approval was granted 4/8/1954 to construct a causeway-tube crossing on an alignment bowed southwards. The plan was for a six-lane tube 7.7 mi in length. Starting in San Francisco, there would be a trestle viaduct approx 5,300' long to a sand island, where traffic would enter one of three 5,800' tubes. They would emerge at another sand island, continue across a low concrete trestle viaduct 22,000' long and then to a 6,000' earthen mole to the SW shore of Bay Farm Island. The route would connect on the Western side with the Bayshore (US 101) and Embarcadero (I-280) freeways. The east bay side would connect with the Posey and Webster Street Tubes (Route 260). It was estimated that the project would take 65,000 tons of reinforcing steel; 1 million cubic yards of concrete; 1.5 million barrels of cement; 10,000 tons of structural steel; and 14 million cubic yards of sand. In 1957, it was reported that a study showed that the crossing would not be financially feasible at a toll rate of 25c, and that it would not be possible to finance construction.

    In 1971, Gov. Ronald Reagan and Bridge Authority Chief Engineer E.R. “Mike” Foley pushed for construction to begin the next year, but San Francisco, Alameda and San Leandro agencies voted against the second crossing. The San Francisco Board of Supervisors cited an increase in traffic that it said would bring more smog and congestion to the city. Foley brushed aside the votes. San Francisco had for 10 years supported the plan, he argued, and the Bridge Authority didn’t need the city’s approval anyway. Powerful Assemblyman Leo Ryan weighed in, saying the second crossing would be a disaster for the recently opened BART system and a “blow to the tenuous ecological balance of the bay.” A bond measure on the ballot in 1972 would have funded a planned crossing from Hunters Point and Alameda, but voters rejected it.

    There were later Southern Crossing proposals, for example, one in 1996 proposed extending Route 238 to Daly City. One author indicates this as I-980; the only record I have is of a rejected proposal for a Southern Crossing and approaches (25mi), with no number stated. The University of California, Berkeley, has an online library exhibit that contains a lot of information about this unbuilt crossing; you can find it at . This would have come approximately from the Route 82/Route 87 junction It is possible that Route 87 may have been the Southern Crossing.

    Note that the Southern Crossing isn't dead yet. In July 2001, the California Transportion Commission was funding a study regarding to the feasibility of a Southern Crossing. However, this later version would have run from I-380 at the top of the San Francisco International Airport to the bottom of the Oakland Airport, for a much longer crossing.

    The San Francisco Bay Crossings Study, dated June 2002, had construction of a new Mid-Bay Bridge (mistakenly called by some the "Southern Crossing", but the actual proposed Southern Crossing was further north) as Alternative 4. This bridge would have connected I-380 to Route 238 in the East Bay. This alternative assumed a connection between I-380 on the west end, just N of San Francisco International Airport, and Route 238. The connection would cross at one of the widest points in the San Francisco Bay. The overall length of the structure would be 13.5 miles, and be the 6th longest bridge, just behind Florida's Sunshine Skyway Bridge. It the main span was connected as 850 feet as proposed in the study, it would be the 5th longest orthotropic steel box girder span in the world.

    The crossing itself would consiste of the bridge structure from the East Toll Plaza to the apporaches at the I-380 interchange. There would be an east and west causeway, and a High Bridge spanning the shipping channel. The causeways would be trestle structures similar to the existing San Mateo Bridge. The SFO Airport Obstruction Clearance Line and glide path would preclude a cable-stayed, suspension, or extradosed type bridge; hence, the High Bridge would be comprised mostly of long-span precast concrete segmental box girders. These would have to be lightweight, as the girder structure would be at the maximum span range (750-850 ft) for this type of bridge in a high seismic region. The causeways would be approximately 12.1 miles long, with the high bridge being approximately 1.1 miles long. The capital cost estimates for this are phenominal: costs for the alternative, including the crossing, approach, right of way acquisition, and transit bus rolling stock, would run from $6.646 billion to $8.245 billion dollars, with operation and maintenance costs of $35 million annually.

    In September 2002, the CTC had on its agenda TCRP Project #11, requested by the Metropolitan Transportation Commission (MTC), to fund $1.8M for completing the feasibility and financial studies for the new crossing alternatives. The TCRP allocated $5,000,000.

    2012 ProposalIn November 2010, the "Southern Crossing" proved itself the proposal that wouldn't die. In early November 2010, saying its mission is to look at long-term options for traffic relief, the Bay Area Toll Authority's oversight committee considered authorizing a $400,000 study on the Southern Crossing Bridge between I-238 in San Lorenzo and I-380 in San Bruno. The odds of the bridge are low: There was no clamor to build the bridge after a study in 2002 estimated the price tag at $8.2 billion. The money for the study would come from tolls collected on seven state-owned toll bridges in the region. Planning consultants hired by the authority would take about six months to update technical information about the Southern Crossing bridge and alternatives for reducing traffic congestion. The toll authority will use the study findings to decide whether to conduct a second, more detailed study with recommendations on whether to build the new bridge. The bridge study would examine the feasibility of developing express bus lanes or rail service on the bridge in addition to lanes for car traffic. Plans for a new bridge spanning the bay have been considered, and rejected for environmental and other concerns, at least five times since 1947. They range from a mirror-image twin of the Bay Bridge to an eight-lane highway and BART bridge from San Leandro to San Bruno and a two-legged bridge shaped like the letter "Y" with one leg to Alameda, the other to San Leandro. Information on this study can be found here.

    MTC looked into the southern crossing in 2012, where the bridge would connect Route 238 in Hayward to I-380 in San Bruno. The Hayward to San Bruno bridge, along with a BART tunnel, would cost up to $12.4 billion, according to a May 2012 presentation to the Bay Area Toll Authority. Rentschler said while Feinstein’s wish for a southern connection is “compelling,” the bigger challenge is getting traffic to flow on either side of the new bridge. According to the May 2012 presentation, at least 61,300 people a day would use the new bridge, and around 27,100 of those would be new transbay trips. Reinstating the defunct Dumbarton Rail corridor — an abandoned rail line that goes from Redwood City to Menlo Park and then across the Bay on a run down railroad trestle — and improving the San Mateo Bridge are alternatives to an entirely new bridge.

    Southern CrossingIn December 2017, the Southern Crossing reappeared in a proposal from Senator Dianne Feinstein, who renewed her call for a new east-west transbay bridge somewhere south of the always-congested Bay Bridge. Feinstein, D-Calif., has repeatedly called since 2000 for a Southern Crossing, an idea that has been around since the 1940s, but has been rejected in recent years as too costly and environmentally problematic. On Wednesday, joined by Rep. Mark DeSaulnier, D-Concord, she sent a letter to Steve Heminger, executive director of the Metropolitan Transportation Commission. The letter chastised the commission for not moving forward on a new transbay span. Its authors said it would relieve Bay Bridge congestion, and that it should be funded by Regional Measure 3, a ballot measure — written, but not yet scheduled — that could raise tolls on state-owned toll bridges by as much as $3. MTC spokesman Randy Rentschler acknowledged receipt of the letter. He said the commission appreciated the acknowledgment of the need for major investment in Bay Area infrastructure. The letter, he said, will be taken seriously. But Rentschler did not commit to undertaking a new bay-crossing study, pointing out that it’s not on the list of projects the Legislature approved when it agreed to let the Bay Area vote on Regional Measure 3 to raise its tolls. Several versions of a Southern Crossing have been proposed through the decades, none of which has been undertaken. After Feinstein floated the idea in 2000, the commission undertook a two-year study of what it would cost. It concluded that building a bridge from Route 238 in Hayward to the Peninsula would cost $8.2 billion, saying that was cheaper than a new BART tube between San Francisco and Oakland but still costlier than the Bay Area could probably afford. Another two-year study, completed in 2012, estimated the cost of a bridge that would carry both cars and some form of transit, at $12.4 billion. Both studies assumed a new crossing that would be built from I-380, in San Bruno, to I-238 in San Leandro. The letter from Feinstein and DeSaulnier included no specifics but did mention “the need for an additional route for both BART and vehicular traffic.” On Wednesday the SamTrans board approved the Dumbarton Corridor study, which is a plan that calls for increasing the frequency of buses across the current Dumbarton bridge and rebuilding the rail bridge for Caltrain or BART.

    In November 2019, it was reported that the Southern Crossing is still not dead. With traffic getting worse, and rush hour now spanning several hours, Sen. Dianne Feinstein and East Bay Rep. Mark DeSaulnier have warmed up an idea that’s stewed since the 1940s: building another bridge south of the first one. It would most likely link Route 238 in San Lorenzo to I-380 near San Francisco International Airport, combining a roadway for cars with some form of mass transit, like BART. Feinstein and DeSaulnier say it would relieve congestion on both the Bay and San Mateo bridges. The lawmakers’ push comes as Bay Area leaders rally to put a transportation mega-tax measure on the November 2020 ballot, trying to generate $100 billion over four decades. One of the key projects under discussion is a new transbay crossing. But the goals of transportation leaders are evolving, and many are eyeing concepts that don’t cater to automobiles. BART and Capitol Corridor are studying the possibility of a second underwater Transbay Tube, which could include rail tracks for Amtrak or Caltrain. Meanwhile, some mass transit enthusiasts envision a bridge that sends bullet trains across the water. Feinstein and DeSaulnier requested the report two years ago when the commission and other groups were pressing for Regional Measure 3, a series of bridge-toll hikes to fund transportation projects throughout the Bay Area. In November 2019, MTC released its most recent report on the matter, “Crossings: Transformative Investments for an Uncertain Future.” It analyzed seven alternatives for a new span. The first two options centered on automobiles: a new southern bridge with two traffic lanes and one carpool lane in each direction, or a rebuilt and widened San Mateo Bridge. Also considered was a BART-automobile hybrid, consisting of twin tunnels beneath the bay — one for cars, one for trains. Two concepts were BART tubes from Alameda to downtown San Francisco, with one of them adding an extension to the city’s Mission Bay. Another was a rail bridge for Caltrain and Amtrak, and a final one combined a new BART tube with a conventional rail crossing. MTC recommended advancing everything except the car-only ideas, saying they provided limited relief for drivers and no help for rush-hour crowds that already overwhelm BART. The car proposals would increase greenhouse gas emissions, the agency said, and could prompt more collisions. By contrast, the rail ideas carried environmental benefits and should be pursued, the report said. As for a car tunnel, commission staff was not enthusiastic. Engineers would have to build new freeway interchanges on both sides of the bay that could displace low-income residents and divide communities, the report said. The project could cost up to $53 billion. DeSaulnier criticized the findings, saying the commission failed to look at the entire Interstate 80-to-Highway 101 corridor, from the Carquinez Bridge to San Francisco International Airport. In a joint statement, he and Feinstein argued that a Southern Crossing for cars and transit would “do more than any other project to alleviate congestion in the region.” Officials at MTC said the current state of the freeways is intolerable but that a new highway bridge would do little to loosen up traffic. “The proposed bridge is hemmed in by freeways that are maxed out on both sides,” Rentschler said. “We could build a 20-lane bridge, and it would still perform poorly,” absent widening the freeways.

Routing Routing

  1. U.S. 395 in 1942, 1965, 2018From Route 15 near Cajon Pass to the Nevada state line passing near Little Lake, Independence, Bridgeport, and Coleville.

    Post 1964 Signage History Post 1964 Signage History

    In 1963, Route 395 was defined as "(a) San Diego to Route 10 near San Bernardino via Temecula and passing near Riverside. (b) Route 15 near Cajon Pass to the Nevada state line passing near Little Lake, Independence, Bridgeport, and Coleville. (c) Nevada state line northwest of Reno to the Oregon state line near New Pine Creek via Alturas."

    In 1969, Chapter 294 transferred the routing that was (a) to other routes. The portion from San Diego to Route 103 [which became Route 15 in 1969] was transferred to Route 163; the portion from Route 103 (present-day Route 15) to Route 71 (present-day Route 15) was transferred to Route 15; and the portion from Route 71 (present-day 15) to Route 31 (present-day Route 15) was transferred to Route 215.

    Thus, the current segment (a) is the original 1963 (b).

    Note that it appears that, prior to the elimination of US 395 signage in San Diego, US 395 ran along 10th and 11th Ave from the southern end of Balboa Park (i.e., where Route 163 and I-5 now meet) to Market Street, where it continued W along Market Street to Harbor Drive (US 101 until it was eliminated and replaced by I-5). The portion along Market appears to have been cosigned with Route 94 (LRN 200). At one point, US 395 may have been extended to the Coronado Ferry which was at the end of Pacific, at least according to some San Diego Council minutes, meaning that the route wasextended down Pacific to Seaport Village. Route 94 may have been moved from Market to the F/G couplet in 1959.
    (Source: Discussion on AARoads, 5/2019. Multiple contributors.)

    There are unconstructed but adopted portions from 3 mi S of Route 18 to 7 mi S of Route 58, and from the San Bernardino County line to 8 mi S of Route 178, for 44 miles parallel to the existing traversable route.

    Another planned freeway adoption was US 395 between the McGee Maintenance Station south to Crowley Lake Dam Road, adopted at the same time before the 1964 renumbering. This was built as an expressway (with one interchange); Old US 395 became "Crowley Lake Road".

    Pre 1964 Signage History Pre 1964 Signage History

    Originally, a number of different state signed routes (and LRNs) corresponded to US 395. It appears that at the June 1934 meeting of AASHTO, US 395 was first created. An August 15, 1934 letter from AASHTO to the State of Oregon indicated that US 395 had just been established running from the Canadian border to San Diego. In California, by the October 1934 or 1935 signage of routes, US 395 was first signed.

    The initial route of US 395 is first shown in clear detail on the 1936 State Highway Map City Insert. US 395 entered the San Diego area southbound using the following route:
    (Source: Gribblenation Blog California State Route 163; Old US Route 80/395 on the Cabrillo Freeway)

    • Fairmount Avenue to US 80 on El Cajon Avenue. It is unclear if US 395 ended at US 80 (LRN 12) at El Cajon Avenue or multiplexed into downtown. It is likely US 80 and US 395 had a mutual terminus at Market Street on 12th Avenue in common terminus points had a precedent in other locations in California.
    • A possible multiplex of US 80 on El Cajon Avenue to Park Boulevard.
    • A possible multiplex of US 80 on Park Boulevard through Balboa Park which became 12th Avenue in downtown San Diego to US 101 on Market Street.

    Of course, after 1964, route numbers were changed again (as detailed above), with US 395 truncated to start at I-15, and earlier portions being subsumed into the new routings of I-15, I-215, Route 74, and Route 163. Specifically, before 1964, US 395 had the following legislative routes and signing:

    1. Between US 101 (present-day I-5) in San Diego and a point just S of the Mirimar Naval Air Station: This is present-day Route 163 and was LRN 77, defined in 1931. Route 71/US 395 started at US 101 near present day University of San Diego. It followed Linda Vista Road to current Route 163, then followed Kearney Villa Road to roughly the present day I-15/Route 163 interchange. Although the original plan was to sign this as Route 71, by October 1935, it was signed as part of US 395.
      • In 1934, the route of LRN 77 was changed. After the change, LRN 77 went down Fairmount and terminated at Route 12 on El Cajon Blvd. US 395 was contiguous with US 80 along LRN 12 until the terminus at Market St and 12th. LRN 12/US 395 was later extended west to Pacific Highway (in 1943) . A 1935 map showing routes to the California-Pacific Exposition in Balboa Park clearly shows several US 395 shields along Fairmount, El Cajon Blvd, and Park Blvd (the last two with US 80 shields also). The State Highway map of 1930 does not show Fairmount Blvd at all, but the State Highway map of 1934 does show Fairmount. Some route US 395 along Fairmont as late as 1948. At the time of this change, the start was also moved to have it start (with US 80) at US 101 in downtown San Diego, later the starting point for Route 163 (more information on this historical portion may be found under Route 163). It headed north on Park Blvd with US 80, then headed east on El Cajon Blvd. It split from US 80 at Fairmont Ave, heading north on Fairmont. It crossed the San Diego River just east of current I-15, then ultimately followed that routing north to Miramar Rd / Pomerado Rd. Thus, it appears (based on input from Steve Varner and Cameron Kaiser) that from 1934-1948, US 395 went north along 12th (Park) with US 80 from Market St and then cut over on A St and north on Park "again" to El Cajon, then left US 80 north on Fairmount (potentially meaning that the "interchanges" on Fairmount were originally part of US 395).
      • Around 1942, US 395 appears to have been routed on Fairmount from Camino Del Rio, up what looks like the old Ward Rd, and then along Murphy Cyn Rd. Around 1948, it was routed to the current Route 163, with the freeway constructed in 1948.
    2. Between a point just S of the Mirimar Naval Air Station and 2 mi N of Temecula: This is present-day I-15, and was LRN 77, defined in 1931. It was signed as Route 71 between Mirimar (Miramar) and Temecula between 1934 and 1935, when US 395 was first signed. US 395 followed what is now Pomerado Road from a point 3 miles north of the I-15/Route 163 interchange to the interchange of Pomerado Road/I-15 at a point just south of the Lake Hodges / San Dieguito River crossing near the southern city limits of Escondido.
      • In Escondido until 1948-49, US 395 was routed 2 blocks to the east of Centre City Parkway along Escondido Blvd. Note how Escondido Blvd has many old motor court style motels from the 20s as well as art deco buildings from the 30s. Note that in the 1950s, US 395 followed four-lane Centre City Parkway. There is still a US 395 mile marker near the downtown area on Centre City Pkwy. Many 1950s era Googie-style cafes remain on this stretch of old highway. Lastly, note that Escondido Blvd (pre-1949 US 395) was actually called San Diego Blvd at the time, as noted on this page from the Escondido Historical Society.
      • One correspondent notes that in 1939 & 1942, US 395 entered Escondido along Escondido Blvd; thence northeast along Grand Ave; thence northwest along Broadway; thence southwest along Mission Ave (old name Grant Ave) and out of Escondido toward Vista. The U. S. Army Corps of Engineers Escondido Quadrangle 1942 edition shows Escondido Blvd north of Grand as only a dry weather road, and California Highways and Public Works magazine September 1939 page 10 has a small scale map that shows US 395 entering Escondido along a street that is probably Escondido Blvd, then going east to another street that is probably Broadway, then north again.
      • US 395 headed west along Mission Ave (former Route 78, now San Diego County Sign Route S14), which turns into South Santa Fe Ave west of San Marcos. It continued to travel E/W along South Santa Fe Ave, and then turned north on Vista Way (San Diego County Sign Route S13) to the current junction with Route 76, following it east. Just to the north of this junction there is a beautiful bridge over the San Luis Rey River (Bonsall Bridge), built in 1925 that was supplanted by a modern crossing in the late 1980s. US 395 followed the current routing of Route 76 to Bonsall, where it diverged from the state route, heading north on Mission Ave (San Diego County Sign Route S13). There is another old US 395 bridge on the south side of Fallbrook that was bypassed with road improvements to South Mission. You can find a description here. Not far south of this bridge there is an old alignment of US 395 (between Fallbrook and Bonsall) that was bypassed called Hellers Bend. The road still has that name.
      • In Fallbrook, US 395 appears to have followed the current routing of County Sign Route S13 through town and made its 90 degree turn at the same place as Mission Ave does today. It then followed County Sign Route S13 to a point less than 1/4 mile east of I-15. It rejoined what is now known as "Old Highway 395" in this area. Note that the current route of Mission Ave changed in the not-too-distant past. Today, Mission Avenue heads north into Fallbrook as "South Mission" Ave. Main Street splits from Mission, heading straight north, while South Mission jogs west, then heads north along what was once Hill Ave. After crossing Alvarado it becomes "North Mission." It currently makes a 90° turn to the east and becomes "West Mission" until crossing Main again after which it is "East Mission", and heads east to the I-15. According to online maps like those on Yahoo, this is the path of County S13. However, if you look on Topozone at the 7.5 minute map, this routing does not exist on the 1968 Morro Hill quad. Instead, from both the topo map and historical descriptions from the Fallbrook Historical Society that are online, it appears that US 395 followed Mission north until it became Main Street, it then turned 90° east on what the topo calls Juniper St (now East Mission). It then jogged north, then east as Mission Road, following that east to the current "Old 395" near the I-15.
      • Much of "Old 395" is still drivable. According to one contributor who lives in that area, Old Highway 395 in that area is still well traveled (and mostly well maintained), functioning mostly as a bypass around the border patrol checkpoint for local traffic. It parallels the southbound side of Route 15 for many miles (well before Route 76) then at/with Mission Road (Fallbrook) crosses over Route 15 to the North side of the freeway (via 2 90 degree turns), parallels I-15 for a few more miles until the Rainbow Valley Blvd exit. where it diverges somewhat and becomes a narrow windy mountain road (with some great vantages over the City of Temecula). Once everything levels out, it runs into Pala Road (sometimes "Pechanga Parkway") about 1/8 mile south of Route 79. South of Route 76, stretches are a narrow mountain road. The abandoned 40-foot Ostrich Creek Bridge in downtown Fallbrook is another relic of old US 395.
      • US 395 diverged again to the south of the grade to Temecula Creek, following Rainbow Canyon Road, where it ultimately joined with current Route 79 (formerly Route 71). The current routing of I-15 was originally a four lane bypass of town, opened in 1949. A relic of the old routing are the two tiny country gas stations on Rainbow Valley Boulevard, their pumps long gone.
    3. Between 2 mi N of Temecula and Riverside: This is present-day I-215, and was LRN 78, defined in 1931. For a time it was signed as I-15E. This was part of Route 194 between 1974 and 1982. Note that, until 1950, US 395 was routed along the route of present-day I-15 from Temecula to the junction with present-day Route 74, then along present-day Route 74 to "D" Street in Perris, and then up "D" Street along present-day I-215. This is shown on some of the older maps. US 395 signage started in 1935 for the dogleg route. The US 395 designation was moved to the I-215 direct routing in 1952-1952, upon completion of construction of the new highway. The older dogleg routing through Elsinore remained as Route 71 (eventual I-15) and Route 74. Note that the routing from Perris to Riverside was originally signed as part of Route 740.

      In 1915, the road through Temecula was first constructed, spawning businesses such as the Swing Inn, known as Mother's Cafe and Alesandro's Place in its earliest days, and other eateries like Mrs. L.M. Hall's Temecula Lunch Rooms, the B-Bar-H Cafe and the Rite-Spot. The two-lane concrete road, built by Riverside County, ran from Perris through Murrieta and into Temecula along Jefferson Avenue and Front Street before heading up the grade toward Rainbow, according to Phil Brigandi's book, "Temecula at the Crossroads of History." Eventually designated US 395, that road and others like it were built to make automobile travel more practical and comfortable. In 1949, US 395 was rerouted out of the business area and up to about where I-15 runs today. There were fears in Temecula that the bypass would severely damage local merchants. A study by the California Division of Highways showed business at the five cafes in Temecula decreased more than 18 percent between 1949 and 1950. However, that same study showed that throughout the entire county the cafe business was also down about 18 percent in the same period.

    4. Between Jct US 60/US 91 and Jct US 60/US 395 (i.e., through Riverside): The route was cosigned as US 60/US 395, and was LRN 19 (defined in 1909). This is currently I-215, although for a time it was signed as I-15E. This was part of Route 194 between 1974 and 1982.
    5. 1944 MapBetween Riverside and San Bernardino: The route was cosigned as US 91/US 395, and was LRN 43 (defined in 1931). This is currently I-215, although for a time it was signed as I-15E. This was part of Route 194 between 1974 and 1982. As the 1944 map shows, US 395 entered into Colton, where the routing dropped the cosigning with Route 18, and continued N along Waterman as LRN 31.
    6. Between San Bernardino and Devore: The route was cosigned as US 91/US 66/US 395, and was LRN 31 (defined in 1915). This is currently I-215, although for a time it was signed as I-15E. This was part of Route 194 between 1974 and 1982. The portion between former US 66 and Route 14 (former Route 7) was originally part of state signed Route 95, defined in 1934, renumbered to US 395 upon the definition of US 395.
    7. Between Devore and 7 mi SW of Victorville: The route was cosigned as US 66/US 91/US 395, and was LRN 31, defined in 1915.
    8. Between 7mi SW of Victorville and the vicinity of Inyokern. The route was signed as US 395, and was LRN 145, defined in 1933. This is part of present-day US 395. The portion between former US 66 and Route 14 (former Route 7) was originally part of state signed Route 95, defined in 1934, renumbered to US 395 upon the definition of US 395 around 1935.
    9. Between the vicinity of Inyokern and Bishop. The route was cosigned as US 6/US 395 (and was formerly Route 7). This was LRN 23, defined in 1909. This is part of present-day US 395. The signage as part of US 395 occurred around 1935.
    10. Between Bishop and the vicinity of Topaz Lake. The route was signed as US 395, and was LRN 23, defined in 1909. This is part of present-day US 395, and was originally part of state signed Route 7. The signage as part of US 395 occurred around 1935.
    11. From Topaz Lake to the Nevada state line. The route was signed as US 395, and was LRN 95. This is part of present-day US 395, defined in 1933, and was originally part of state signed Route 7. The signage as part of US 395 occurred around 1935.

    East of the Route 203 interchange, "Old Highway" takes a routing parallelling Mammoth Creek for a bit and crossing it a bit northeast of the current US 395 expressway. It serves as a connection to several local roads, including a forest route along Antelope Springs Road. However, it is unclear if Old Highway directly connects with existing US 395 (Mapquest shows it as doing so; MSN's map service does not).

    An "Old State Highway Road" parallels Route 120/US 395 from south of West Portal Road on the east side of Grant Lake all the way north to Oil Plant Road south of Lee Vining. (This is shown on Mapquest and on Compass's maps.)

    General Southern US 395

    In November 2011, the first workshop for the "Historic Highway 395 Corridor Study" project, also known as the Jefferson Avenue Corridor project, was held in Murrieta. The 16-mile arterial corridor is proposed to parallel the west side of I-15 where old US 395 used to travel. It would extend from Rancho California Road along Jefferson Avenue through the cities of Temecula and Murrieta, continuing along Palomar Street and Mission Trail through the cities of Wildomar and Lake Elsinore, and continuing along East Lakeshore Drive to Main Street in Lake Elsinore.

The specifics of this aren't given, but it could relate to the High Desert Corridor and the Cross-Valley Connector (see Route 138), which when combined with the I-5 to Route 14, and US 395 to I-15 segments, would complete the Metropolitan Bypass Freeway. The funding, however, is insufficient to complete this. $800,000.
    • High Priority Project #1342: Construction of new freeway between I-15 and US 395, including new interchange at I-15. This is the last part of the High Desert Corridor (see Route 138). This will provide new highway access to the Southern California Logistics Airport. $4,000,000.
    • High Priority Project #2427: US 395 Realignment and Widening Project. $400,000.

    In July 2007, the CTC relinquished right of way in the city of Hesperia, at Outpost Road, consisting of reconstructed and relocated city street. The City, by relinquishment cooperative agreement dated April 16, 2007, waived the 90-day notice requirement and agreed to accept title upon relinquishment by the State.

    US 395 Expressway / Realignment

    There are currently plans to realign US 395 near the cities of Oak Hills, Hesperia, Victorville, Adelanto and incorporated areas of San Bernardino County. This is based off of a draft EIR. The plan is to realign US 395 from the I-15/US 395 interchange (approx SBD R3.981) to Farmington Road. The proposed US 395 Realignment Freeway/Expressway corridor to be evaluated is located either on existing US 395 or west of existing US 395, through the cities of Oak Hills, Hesperia, Victorville, Adelanto and incorporated areas of San Bernardino County. The entire proposed project length is approximately 45.0 miles long. There are four alternatives currently being considered:

    • Alternate A: No Build. This Alternative consists of no change to existing facilities along the proposed project portion of the US 395 corridor.
    • Alternative D: Existing Alignment. The Existing Alignment Alternative follows the existing alignment or a slightly offset alignment throughout the project limits.
    • Alternative F: Realignment West of Existing Corridor. This Alternative proposes to realign the corridor from the I-15/US 395 interchange to Farmington Road. This realignment heads northwest in the vicinity of the Oak Hills Community and the Union Pacific Railroad, and then continues in a northerly direction just west of Caughlin Road within San Bernardino County limits and traversing the western portions of the City of Adelanto, where it converges back to paralleling the existing US 395 alignment for the remainder of the project limits.
    • Alternative G: Realignment West of Existing Corridor along Oro Grande Wash. This alternative consists of a realignment detaching from existing the I-15/US 395 interchange, where immediately crosses the Union Pacific Railroad within the first 1½ miles heading northeast along the Oro Grande Wash. the realignment continues northeasterly throughout the western portions of the Cities of Hesperia and Victorville and follows in a northerly direction just west of Cuaghlin Road within San Bernardino County limits and traversing the western portions of the City of Adelanto where it converges back to paralleling the existing US 395 alignment for the remainder of the project limits.

    In June 2016, it was reported that state financial issues have resulted in all STIP funding being removed from the 395 Expressway Project which would widen Route 395. But Caltrans will continue to seek funding to complete widening of existing Route 395, according to Caltrans spokeswoman Terri Kasinga.

    US 395 Widening - I-15 to Route 18 (~ SBD R3.99 to SBD 11.22)

    In March 2015, the CTC approved for future consideration of funding a project in San Bernardino County that will construct operational efficiencies on US 395 from 0.16 mile north of the junction of US 395 and I-15 in the city of Hesperia to approximately 1.80 miles south of Desert Flower Road in the city of Adelanto. The project is programmed in the 2014 State Transportation Improvement Program. The total estimated cost is $55,191,000 for capital and support. Construction is estimated to begin in Fiscal Year 2016-17. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2014 State Transportation Improvement Program.

    In July 2018, it was reported that this phase has received environment clearance, and is on hold pending construction funding.

    US 395 Widening - Route 18 to Chamberlaine Way (SBD 11.2 to SBD 16.3)

    U.S. 395 Widening Phase 1 - Rte 18 to Chamberlain WayIn March 2015, the CTC allocated $5,550,000 to SANBAG for US 395 Interim Widening. In Hesperia, Victorville and Adelanto. Widen US 395, from Route 18 to Chamberlaine Way (08-SBd-395, PM 11.2/16.6), from two lanes to four lanes and construct left-turn channelization at various intersections.

    In August 2016, it was reported that Measure I funding included widening of US 395 from Mojave Drive (~ PM SBD 12.633) south to Star Street (~ PM SBD 12.385), which is expected to cost $4.1 million, with 63.5 percent of the funding required from development impact fees.

    The 2018 STIP, approved at the CTC March 2018 meeting, appears to allocate $9.333M for PPNO 0260J Widening, Rt 18-Chamberlaine Way (~ SBD 11.22 to SBD 16.742).

    In July 2018, it was reported that work was scheduled to begin in Fall 2018 on nearly $60 million in improvements to the busy stretch of highway between Route 18 and Chamberlaine Way — a major freight traffic route and passenger corridor that connects economic centers, recreation areas, cities and rural communities. These improvements will widen that portion of the highway by providing two lanes in each direction, and includes the addition of turn pockets and signals at key intersections along the corridor. The start of construction is the culmination of years of planning and securing the funds needed to make it happen, including nearly $18 million in voter-approved Measure I funds, the half-cent sales tax measure for San Bernardino County. The San Bernardino County Transportation Authority (SBCTA) is partnering with the California Department of Transportation (Caltrans) to see this and subsequent phases of the 395 improvement project through completion. Tthe Victorville-to-Adelanto leg is just one of three phases of an overall US 395 plan for which state and federal funds have been secured. Those future phases — from Interstate 15 to State Route 18 and from Chamberlaine Way to Desert Flower Road — have received environmental clearance and should begin once those additional funds are obtained. It is anticipated to be open in Fall 2020, with project closure in late 2021.

    US 395 Widening - Adelanto (SBD 15.95) to Desert Flower Road (~ SBD 21.086) and beyond to SBD 36.40

    Adelanto Rumble StripsIn May 2012, the CTC approved for future consideration of funding a project in San Bernardino County that will widen the median and shoulders along US 395 (PM 15.95 - PM 36.40), install rumble strips, resurface the roadway, and widen the following intersections to accommodate the new width of US 395: Colusa Road. Desert Flower Road. Purple Sage Street, Shadow Mountain Avenue, Sun Hill Ranch, and Princess Pat Mine. The project is programmed in the 2010 State Highway Operation and Protection Program (SHOPP). The total estimated project cost is $55,460,000 for capital and support. Construction is estimated to begin in Fiscal Year 2012-13. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2010 SHOPP.

    In July 2018, it was reported that this phase (at least the portion between Adelanto and Desert Flower Road) has received environment clearance, and is on hold pending construction funding.

    In August 2018, the CTC approved $15,171,000 in SHOPP funding for San Bernardino 08-SBd-395 35.5/39.1 US 395 Near Adelanto, from 1.0 mile south of Kramer Hills to 2.6 miles north of Kramer Hills. Outcome/Output: Widen median and shoulders and construct rumble strips. This project will increase safety and reduce the number and severity of collisions.

    Kramer Hills Widening

    395 Kramer HillsIn October 2015, the CTC approved for future consideration of funding a project in San Bernardino County that will construct a median barrier, widen shoulders, and install rumble strips on US 395 near the community of Kramer Hills. The project is programmed in the 2014 State Highway Operation and Protection Program. The total estimated cost is $40,657,000 for capital and support. Construction is estimated to begin in Fiscal Year 2017/18. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2014 State Highway Operation and Protection Program. A copy of the MND has been provided to Commission staff. (Approx SBD 38.633 to SBD 46.207)

    In August 2017, the CTC allocated $28,597,000 for San Bernardino 08-SBd-395 39.0/45.9 US 395: Near Adelanto, from 2.5 miles north of Kramer Hills to Route 58. Outcome/Output: Widen median and shoulders and construct rumble strip to reduce the number and severity of traffic collisions. Future consideration of funding approved under Resolution E-15-56; October 2015.

    In August 2019, it was reported that construction crews are working on two projects south of the intersection of US 395 with Route 58 where they’re widening shoulders to eight feet, placing centerline and shoulder rumble strips and reinstalling two passing lanes south of Kramer Junction, going both ways. Striping will also be widened from four to six inches on the entire stretch of US 395 from I-15 to the Kern County line. In some sections, Caltrans has also put in channelizers — thin fiberglass paddles — that will help deter crossing the double-yellow lines. The three projects should be completed by the end of the year at an overall cost about $35.5 million. Some of that total is funded with Senate Bill 1 funds, the so-called “gas tax,” according to a Caltrans document.
    (Source: Victor Valley Daily Press, 8/19/2019)

    In California City, there is a proposal for a new road that would run from Muroc Junction following the alignment of Rosamond Boulevard at the Edwards Air Force Base north gate. The road would curve to connect with California City Boulevard at the curve just south of the city. It would then proceed north to connect with 20 Mule Team Parkway, which would be paved all the way to its current connection with US 395. This will provide a faster connection between Edwards AFB and the Naval Air Weapons Center.

    Olancha Bypass (09-Iny-395 29.2/41.8)

    Olancha WideningIn 2007, the CTC did not recommend funding construction of the Olancha and Cartago Expressway ($107,600K total cost; $59,000K requested) from the Corridor Mobility Improvement Account (CMIA). However, the minutes from the 11/08 meeting of the Inyo County Local Transportation Commission discussed the five options for US 395's realignment (either expansion or a movement west). The main problem is the proximity of the LA Aqueduct.

    In February 2016, it was reported that discussions of the Olancha Bypass continue. The Caltrans preferred alternative is a bypass of the community that has Olancha residents in an uproar. Although the bypass alternative seems to be the much safer option, Olancha residents don't want to lose the business highway traffic brings into the already struggling town. Olancha residents claim the bypass alternative is unfair because the other towns on the US 395 corridor in Inyo country (Bishop, Big Pine, Independence, Lone Pine) got to keep the highway running through town. If the bypass alternative is chosen the current alignment will be turned into a combination of a local road and an extension of Route 190, a major state route taking year round visitors to Death Valley National Park. The bypass routing would be to the west, close to the base of the Sierras, which would give travelers a beautiful view. The extension of Route 190 would be to the south, through Olancha, terminating at an intersection with the newly aligned US 395.

    In August 2017, the CTC approved for future consideration of funding 09-Iny-395 PM 29.2/41.8 Olancha/Cartago Four-Lane Project: This project in Inyo County will construct two new lanes (one new lane in each direction) on a portion US 395 near the town of Olancha. The project will increase safety and the Level of Service. The project is not fully funded. The project will be funded from State Transportation Improvement Program (STIP) funds and is currently programmed in the 2016 STIP for an estimated $16.6 million Right of Way (capital and support). Construction is estimated to begin in Fiscal Year 2020-21. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2016 STIP. A copy of the FEIR has been provided to Commission staff. Resources that may be impacted by the project include community impacts, noise, water quality, air quality, cultural resources, paleontological resources, hazardous waste, aesthetics, and biological resources. Potential impacts associated with the project can all be mitigated to below significance. As a result, an FEIR was prepared for the project. Note that this appears to be distinct from the once-proposed Olancha Bypass.

    395 Olancha BypassIn January 2018, the CTC approved a request from the California Department of Transportation’s (Department) to adopt US 395 in Inyo County from INY 29.9 to INY 41.9 as a controlled access highway, redesignate a segment of superseded US 395 as Route 190 and, upon construction completion of the new controlled access highway, relinquish the remaining portion of the superseded US 395 to Inyo County. The Department proposes to adopt this 12.14 mile section of US 395 to construct a new expressway within the adoption limits, which will improve safety for the traveling public, raise the level of service, and provide a continuous four-lane facility in Inyo County. A final Environmental Impact Report/Environmental Assessment (EIR/EA) prepared pursuant to the California Environmental Quality Act and the National Environmental Policy Act was approved by the Department on March 7, 2017 and by the Federal Highway Administration (FHWA) on May 26, 2017. The Department approved a project report on June 27, 2017 recommending construction of the new US 395 expressway on a new alignment and redesignation of a portion of the superseded segment as Route 190. The remaining portion of the superseded highway will be relinquished to Inyo County after project construction completion.

    Within the proposed adoption limits, US 395 is currently a two-lane undivided conventional highway. It traverses gently sloping terrain at elevations between 3,600 and 3,900 feet as it passes through the communities of Olancha and Cartago. Olancha is sparsely developed with a few businesses, a post office, and one service station. Cartago is located about three miles north of Olancha and is primarily a residential community. There are a few businesses and residences adjacent to the highway, but in general, the highway corridor is rural in nature. This project will connect the four-lane divided expressway segments at both ends of the adoption limits.

    The existing highway generally consists of two 12-foot lanes and 8-foot paved shoulders within 100 feet of right of way. There are no shoulder improvements such as curb, gutter or sidewalk throughout this section of the highway. There is no median and approximately 50 percent of the highway is barrier striped to prevent passing. There are undivided passing lanes for both northbound and southbound traffic north of Cartago. The posted speed limits vary from 65 mph outside of the communities to 55 mph within the communities. In addition to the intersection with Route 190, there are six other public road connections and numerous other private roads and access points to the existing highway within the project limits.

    Due to the numerous access points and limited sight distances along US 395, passing zones are limited. There is also a mixture of slower recreational and commercial vehicles, local residential and business traffic, and faster through traffic. The limited passing opportunities and mixed traffic has led to queuing within the communities, driver frustration, and frequent unsafe passing maneuvers. In 2006, shoulders were widened and the posted speed limit reduced within the communities, but the fatal accident rate remained at 1.29 times the statewide average. This section of highway is currently operating at Level of Service (LOS) D and is projected to fall to LOS E within the 20-year planning period.

    The proposed route adoption will allow the Department to construct the expressway on a new alignment. It will eliminate traffic congestion and significantly increase safety for the traveling public by separating opposing traffic, removing passing restrictions, and controlling access points. Finally, the new expressway will provide route continuity on US 395 and will complete the construction of four-lanes throughout the US 395 corridor in Inyo County.

    A draft project report was approved in September 2010 to evaluate five alternatives. Their environmental impacts were evaluated in an Initial Study/Environmental Assessment circulated end of 2010. Focused studies performed for the preferred alternative determined that mitigation of cultural impacts to insignificant levels may not be possible. As a result, the environmental document was elevated to a Draft Environmental Impact Report/Environmental Assessment (EIR/EA) which allowed the Department to discuss the potential cultural impacts and evaluate the preferred alternative. The Draft EIR/EA was circulated from August to October 2015, after which the preferred alternative was selected.

    The portion of the existing highway between the intersection with Route 190 and the southern intersection with the new expressway is proposed to be redesignated as Route 190. A concurrent Commission’s action to approve the redesignation of this portion of US 395 as Route 190 is on the January 2018 Commission agenda. This action will reestablish the terminus of Route 190 at US 395. The remaining portion of the superseded highway between the intersection with Route 190 and north of the community of Cartago will be relinquished to Inyo County after project completion. The superseded highway will continue to provide a local route that preserves the existing uses and access along the existing corridor. The project will also construct or reconstruct a couple other county roads, all of which will be relinquished to Inyo County.

    This project has been jointly funded by the Inyo County Local Transportation Commission, Mono County Local Transportation Commission, Kern Council of Governments, and the Interregional Improvement Program. Due to shortfalls in the programming available for the 2016 State Transportation Improvement Program (STIP), the Construction Capital and Construction Support components were deprogrammed. Funding for the Construction Capital and Construction Support components have been restored in the proposed 2018 STIP. The estimated total cost of the project, including construction and right of way costs escalated to the year of construction, is $138,819,000. The project is scheduled to start construction in September 2020.The Department and Inyo County have agreed with the public road openings proposed for the new expressway and intend to execute a Controlled Access Highway Agreement following the Commission’s approval of this route adoption. Currently, the Department and Inyo County are negotiating the terms of the relinquishment agreement. Inyo County has agreed in principle to accept the relinquishment of the facilities.
    (Source: CTC Agenda, January 2018, Agenda Item 2.3a(1))

    The 2018 STIP, approved at the CTC March 2018 meeting, appears to restore funding from this, moving the total from $11,420K to $41,487K, including an additional $23,495K in FY21-22, presumably for construction. The project is near Olancha and Cartago, south of the Los Angeles Aqueduct Bridge to south of the Ash Creek Bridge. Widen 2 lane conventional highway to 4 lane expressway. There also appears to be additional funding for this from the Kern and Mono County shares.

    Manzanar Improvements (approx INY 67.69)

    In October 2004, the CTC considered adoption of 2.6 kilometers (1.6 miles) of Controlled Access Highway for Route 395 from 2.9 kilometers (1.8 miles) south of Mazourka Canyon Road to 0.3 kilometers (0.2 mile) south of Mazourka Canyon Road in Inyo County. Currently, this segment of Route 395 is a two-lane conventional highway crossing generally level terrain. Cross-section consists of two standard 3.6 m (12 ft) lanes with predominantly non-standard 1.2 m (4 ft ) shoulders, where 3 m (8 ft) is standard. At the southern limit of the adoption, the route will connect to the recently approved Manzanar four-lane divided section (Resolution HRA-04-02 approved August, 2004). This segment south of Independence was not included in the Manzanar adoption, as it was an integral part of a possible Independence bypass alternative and subject to various alignment considerations. This bypass alternative had less than a 3% approval at public hearings and was ultimately rejected for the recently approved 4-lane improvement project through Independence. Current and twenty year projected Level of Service (LOS) for the existing facility is ‘D’, congested. The current and twenty year LOS for the proposed project is ‘A’, free flowing. The majority of the property through which this segment of the route passes is owned by the Los Angeles Department of Water and Power, with little development adjacent to the existing or proposed right of way south of Independence. The route adoption proposes a controlled access highway on predominantly existing alignment from the northern end of the Manzanar four lane section adopted in August, 2004, to a point 0.3 kilometers (0.2 miles) south of Mazourka Canyon Road, at Independence. Construction is currently scheduled for FY 2007-08, based on programming in a 2004 STIP. ([PDF] ref)

    The four lane project between Lone Pine and/through Independence is nearly completed as of August 2010. The last portion is around Manzanar where a new bridge is being completed for the southbound alignment; the northbound alignment is pretty much intact. The new alignment in Manzinar leaves a stretch of the old alignment as a frontage road, and the only connection from the new US 395 to the frontage road is at Manzanar Reward Rd. This means all of US 395 from Inyokern to Conway Summit is four-lane expressway except for the piece through Olancha which is unlikely to be upgraded anytime soon. The segment was completed in October 2010.

    In January 2011, the CTC vacated right of way in the county of Inyo along Route 395 at the Manzanar National Historic Site, consisting of superseded highway right of way no longer needed for State highway purposes.

    In Independence (roughly INY 73.35), Caltrans is attempting to widen US 395. However, trees are in the way, according to an article in the LA Times. Specifically, Caltrans engineers say 100 trees are standing in the way of plans to widen a stretch of the route in Independence from two to four lanes and line it with about 400 feet of sidewalks. The project, they say, would improve safety and the flow of vehicles on the rural fringe of the community. The issue has its roots in Caltrans' decade-old proposal to widen US 395 to four lanes between Ridgecrest and Mammoth Mountain. The mile-long stretch, edged with dirt shoulders, is among the last to be expanded.

    In August 2003, the CTC considered relinquishment of the county road and frontage road portion of Route 395 between PM 90.9 and PM 99.6 (i.e., between South Fish Springs Road and Big Pine Dump Road) in the County of Inyo. Also considered was vacation of the right of way in the County of Inyo, between North Fish Springs Road and 0.25 mi S of the Town of Big Pine, that is a right of way superseded by construction on a new alignment. In September, the CTC considered relinquishment of right of way in the County of Mono (County), at Utility Road (County Road No. 3203), consisting of reconstructed and relocated county road.

    Bishop Area (approx INY 115.341) Access and Circulation

    [Bishop Bypasses]In 2003 the Inyo County Local Transportation Commission, with the support of the City of Bishop and Inyo County, requested that Caltrans District 9 conduct a Bishop Area Access and Circulation Study. This study was published at The basic goal was to develop a plan and alternatives to (1) Improve circulation and safety for all modes of transportation in the downtown area. (2) Accommodate commercial truck traffic for US 395 and US 6. (3) Plan for downtown improvements (i.e. landscaping, parking, pedestrian facilities, etc.) along with the rerouting of truck traffic. (4) Facilitate ground access improvements to the airport and its associated development improvements. (4) Keep services in Bishop visible for through-traffic on any route and have easy on/off connections. The plan notes that a bypass of the Bishop business district was considered in 1966 (see but traffic didn't justify it; the alternatives from that plan are no longer practical as the land is either privately owned and developed, or tribal lands. The basic recommendations of this study (which has not been adopted yet by the CTC) are:

    1. A two-lane eastern alternative truck route beginning somewhere between Gerkin Road and Schober Lane and connecting back to US 6 and US 395 at the Wye Road location. This new route should be developed as a City/County road to Caltrans standards in order to allow the City and County the option to exchange this route for Main Street/US 395 at sometime in the future.
    2. Improved access between the City and the housing areas to the west (i.e. South Barlow, Manor, McLaren, Highlands/Glenwood, Meadow Creek, Bishop Reservation, etc.). This recommendation includes the development of new local roads to provide options other than Route 168/West Line Street and US 395/North Sierra Highway to get into town.
    3. Improved City street alternatives to Main Street/US 395 that accommodates north/south movements of local traffic on either side of Main Street.

    Some other interim recommendations from the report include: better alignment of the Wye Road/US 6 intersection and the eventual reconfiguration of the US 6/US 395/ Wye Road intersection; the aligning of side streets off of Main Street/US 395 to create at least one more full four way intersection; extending See Vee Lane north of US 395; signalizing the See Vee/US 395 intersection; and defining access along the North Sierra Highway corridor with sidewalks and driveways.

    As of May 2009, Cameron Kaiser reports that most of the pass closure signs have been replaced with automated flashers, including the Caltrans-erected one in the Carson Valley, but there is still an old clapboard sign south of Route 89. There have also been significant widening projects. There seems to have been some widening and four-laning in the Antelope Valley, mostly between Topaz Lake and Coleville. The route is still one-lane-per-direction between Devils Gate and Coleville, and of course a fair bit south of Bridgeport and around Mono Lake. Repaving is taking place on the Sherwin Grade, as well as a big resurfacing project north of the Bishop city limits. The 4-lane project for Inyo is proceeding but in several distinct phases. The first phase from Black Rock to Elna Rd is apparently complete but now they're repaving the original (NB) lanes, so everyone uses the new southbound lanes. The rest area isn't done. There is a second phase from Black Rock to Independence which has some asphalt and grading work on its new NB lanes but is not nearly as complete. Independence's street widening project is in full swing. All of the sidewalks have been torn up and the traffic lanes shifted over while work is done on the original NB side. No paving or concrete yet but the entire new section(s) are fully graded in preparation for moulds. The final phase is from Independence to Lone Pine via Manzanar. This only looks just started; there is only grading existing on the new NB lanes, no asphalt and no bridgework (several of the channels will need culverts or bridges).

    U.S. 395 near Toms PlaceIn October 2018, the CTC approved for for future consideration of funding the following project for which a Mitigated Negative Declaration (MND) has been completed: US 395 in Mono County (09-Mno-395, PM 6.92/9.62). Widen existing shoulders on a portion of US 395 in Mono County. (PPNO 0662) This project is located on US 395 between Bishop and Toms Place in Mono County. The project proposes to widen the existing paved highway shoulders at the project location. The proposed project addresses the need to reduce the number and severity of collisions and enhance safety. Also included in the proposed project will be added rumble strips, replacement of guardrails, upgrading of drainage systems, modification to slopes for improvement in sight distances around curves and additions to bicycle right turn lanes. The proposed project is currently estimated to cost approximately $22.5 million. This project is fully funded and is currently programmed in the 2018 SHOPP for approximately $20.4 million which includes Construction (capital and support) and Right-of-Way (capital and support). Construction is estimated to begin in Fiscal Year 2020-21. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2018 SHOPP.
    (Source: October 2018 CTC Agenda Item 2.2c.(1))

    In May 2019, the CTC approved for future consideration of funding a project located on US 395 between the towns of Mammoth and June Lake (09-Mno-395, PM 30.7 & 36.5), in Mono County. The project proposes to pave three locations to provide off-highway parking to access hiking, bicycle and snowmobile trails along US 395. The project addresses the need to provide winter access parking for recreations users and to avoid parking on highway shoulders creating potential hazard for snow plowing and motorists. The proposed project has been developed and studied in conjunction with the US Forest Service-Inyo National Forest. The estimated total overall cost of the project is $1.6 million. The project is not currently programmed in the SHOPP. The project is estimated to begin in Fiscal Year 2020-21.

    In August 2015, the CTC authorized vacation of right of way in the county of Mono along Route 395 at Material Site Number 190, approximately 0.8 mile north of Route 120 (approx MNO 51.595), consisting of highway right of way (a material site) no longer needed for State highway purposes. The site will revert to the Bureau of Land Management.

    In May 2019, the CTC deleted the long-lead project 09-Mno-395 69.9/71.9. PPNO 2639. Proj ID 0917000014. On US 395 Near Bridgeport, from north of Route 270 Junction to Green Creek Road.

    Fales WideningIn August 2017, the CTC approved for future consideration of funding 09-Mno-395 PM 88.42/91.55 Aspen Fales Shoulder Widening Project: This project in Mono County will widen shoulders on US 395 in the town of Bridgeport. The project will improve safety and operations for the traveling public. The project will be funded from State Highway Operation and Protection Program (SHOPP) funds and is programmed in the 2016 SHOPP for an estimated $14.2 million Construction (capital and support) and Right of Way (capital and support). Construction is estimated to begin in Fiscal Year 2018-19. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2016 SHOPP. A copy of the FEIR has been provided to Commission staff. Resources that may be impacted by the project include visual and aesthetics, cultural resources, noise, and biological resources. Potential impacts associated with the project can all be mitigated to below significance. As a result, an FEIR was prepared for the project.

    In January 2019, the CTC approved the following allocation: $9,555,000 Mono 09-Mno-395 88.4/91.6. US 395 Near Bridgeport, from north of Devils Gate Summit to Burcham Flat Road. Outcome/Output: Widen shoulders and construct rumble strip. This project will reduce the number and severity of collisions. Future consideration of funding approved under Resolution E-17-54; August 2017. Related supplemental funds vote to re-advertise EA 35780/PPNO 09-0615 under Ref. 2.5e.(2), Resolution FA-18-36.

    In July 2019, Caltrans began holding preliminary meetings on the Aspen-Walker Shoulder Widening Project, which will widen the highway shoulders from the existing width of 2-3 feet to 8 feet, as well as construct retaining walls and install rumble strips. The project will run along US 395 from 5 miles south of Sonora Junction at State Route 108 to 2 miles north of the junction (~ MNO 88.765/MNO 95.765).

    In January 2019, the CTC approved a request for an additional $2,985,000 for the State Highway Operation Protection Program (SHOPP) Collision Severity Reduction project (PPNO 0615) on US 395, in Mono County, to re-advertise the construction contract. This project is located on US 395, near the town of Bridgeport, in Mono County (09-Mno-395 93.4/95.7). The project will widen shoulders, install rumble strips, replace and upgrade guardrails, install new concrete barriers, improve roadway cross-slope and stopping sight distance, and install rock-fall protection to reduce the severity and number of collisions. The performance measure goal is to reduce collisions by 28 collisions and improve 2.9 lane miles from “fair” to “good” condition and improve one census station from “poor” to “good” condition. The improvement is consistent with the Commission-adopted goals and objectives of the Transportation Asset Management Plan. As of January 2019, all contract bids have been rejected. The Department will re-advertise the contract upon approval of this supplemental funds request. The updated certified Engineers Estimate and adjusted project cost is expected to attract more bidders when the project is re-advertised in February 2019 if this supplemental fund request is approved. Over the last half year, the Department has seen a trend that shows a significant increase in the cost of materials and significant decrease of available contractors and subcontractors in a busy construction market. Based on the discussion with several non-bidding contractors, the Department believes that readvertising the project is in the best interest of the State, as the Department is combining this project with the Aspen Fales Shoulder Widening Project, for construction. This will help decrease the overall costs and allow the contractor to control the entire operations of both projects, therefore eliminate dueling prime contractors and subcontractors working adjacent to each other. The Department will also perform contractors outreach events during the advertisement period. The Department will also make available a site near the city of Lee Vining for contractors use as the Baseline Material Site. In addition, both projects to the north and south, have since been completed so the project is no longer “land-locked” between ongoing construction or competing contractors. Based on conversations with those non-bidding contractors, this could also provide a more favorable bidding environment upon re-advertising the project.

    Naming Naming

    The portion of this route that was cosigned with US 6 (i.e., from Route 14 to US 6 in Bishop (~ KER 26.958 to INY 114.898) was named the "Grand Army of the Republic Highway" by Assembly Concurrent Resolution 33, Chapter 73, in 1943.

    Historically, the portion of this route from Route 14 to Bridgeport (~ KER 26.958 to MNO 76.758) was part of "El Camino Sierra" (Road to the Mountains).

    The segment of US 395 from Gill Station Coso Road to the junction with Route 190 in the County of Inyo (~ INY R17.857 to INY 34.479) is named the "Paul H. Pino Memorial Highway". This segment was named in memory of California Highway Patrol Officer Paul H. Pino, badge number 9735, who was killed in the line of duty during the morning of December 30, 2003. Paul H. Pino was issuing a citation on US 395 south of Olancha in the County of Inyo when an impaired driver collided into his patrol vehicle killing the officer; he succumbed to his injuries as a result of the collision. Officer Pino was born on August 26, 1955, in The Hague, Holland. He immigrated to the United States in 1960 and subsequently relocated to Carson, California. He attended and graduated from Carson High School in 1973; from Los Angeles Harbor College with a degree in Police Science in 1977; and joined the Los Angeles County Sheriff's Department as a Deputy Sheriff in 1977 and served in that capacity for three years. He joined the California Highway Patrol in August, 1980. After successfully completing his academy training, he reported to the South Los Angeles Area as an officer on January 8, 1981. Paul H. Pino made significant contributions to traffic safety and assisting the motoring public while assigned to the South Los Angeles, Barstow, and Bishop Area offices; in total, he served 23 years as a sworn peace officer for the California Highway Patrol and was known by his fellow officers for his dedication to the department and to the protection of the citizens of our state. Named by Senate Concurrent Resolution (SCR) 55, Resolution Chapter 50, on 5/9/2006.

    The segment of US 395 from its intersection with Warm Springs Road in Inyo County to the southern city limits of Bishop (~ INY 112.873 to INY 114.853) is named the "Police Officer Richard Perkins Memorial Highway". Named in honor of Officer Richard E. Perkins of the Bishop Police Department, who was killed in the line of duty on August 15, 2001, when a truck struck his patrol car as he was making a turn in order to assist another law enforcement agency in pursuit of a possible drunk driver. Officer Perkins was an 11-year veteran of the Bishop Police Department, was highly respected in the community he served, and is survived by his wife Cheryl and three children, Andrew, Pauli, and Kati. He was the first police officer to die in the line of duty in the City of Bishop's 100-year history. He was dedicated to family, friends, church, and the community, and was known for his work with the Bishop Mural Society and as one of the founding members of the Bishop Police Mounted Unit. Named by Senate Concurrent Resolution 46, Chapter 53, May 5, 2004.

    Just off of US 395 is the community of Bodie (exit at Route 270, MNO 0.064) Bodie has been designated the Official State Gold Rush Ghost Town. Bodie was founded by Waterman S. Body in 1859, and rose to prominence due to mining in the nearby Comstock Lode. At its peak in 1879, Bodie boasted a population of 10,000 citizens and had a reputation for its wicked climate as well as its clientele. By 1882, the big strikes were mostly gone and with them the need to stay in Bodie. One hundred twenty years later, in 2002, Bodie is one of the largest and best-preserved ghost towns in the West. Designed by Assembly Bill 1757, Chapter 365, 9/5/2002.

    The portion of US 395 from the South Buckeye Creek Bridge (Bridge 47–33; MNO 79.168) to the junction of Route 182 (MNO 76.3) in the County of Mono is named the "Senator David E. Cogdill, Sr., Memorial Highway". It was named in memory of Senator David E. “Dave” Cogdill, Sr., born in December 1950, in Long Beach, and was raised in San Bernardino until moving with his family, in his senior year of high school, to Bridgeport. After high school, Senator Cogdill enlisted in the United States Air Force and served as a member of the Air National Guard. Senator Cogdill began his professional career in Bridgeport in 1971, as a clerk-typist in the Mono County Assessor’s Office, eventually becoming Chief Appraiser, then, at the end of the decade, moved to Modesto, where, in 1981, he and David R. Giomi cofounded the appraisal firm Cogdill & Giomi, which became one of the oldest, best known, and most respected appraisal firms in the Central Valley. In Bridgeport and Modesto, Senator Cogdill demonstrated a tireless commitment to his church and community, taking on leadership roles in organizations ranging from the Bridgeport Fire Protection District, the Bridgeport Volunteer Fire Department, and the YMCA of Stanislaus County to the Modesto Chamber of Commerce and the Modesto City Council. In 2000, Senator Cogdill was elected to the California State Assembly to represent the 25th Assembly District, which included Calaveras, Mariposa, Mono, and Tuolumne Counties, and portions of Madera and Stanislaus Counties, and, during his six-year tenure, became Assembly Minority Floor Leader. During this time, Senator Cogdill, with Senator Charles S. “Chuck” Poochigian, revived the California State Legislature Rural Caucus to amplify the concerns of rural communities, including by collaborating with local leadership to advocate for access to health care and quality education in those communities. In 2006, Senator Cogdill was elected to the California State Senate to represent the 14th Senate District, which included Mariposa and Tuolumne Counties and portions of Fresno, Madera, San Joaquin, and Stanislaus Counties, and, in 2008 and 2009, was Senate Republican Leader. As Senator, Senator Cogdill was recognized as Senate Small Business Legislator of the Year by the California Small Business Association, and honored by the John F. Kennedy Library Foundation with the prestigious Profile in Courage Award for taking on a challenging leadership role during the first year of the state budget crisis of 2008–12. Senator Cogdill remained active in community and statewide organizations after leaving the Legislature, becoming Stanislaus County Assessor in 2011, and President and Chief Executive Officer of the California Building Industry Association in 2013. Through his untimely death on July 23, 2017, at 66 years of age, Senator Cogdill was a man of faith, stoic and steadfast, who strove to do more than his duty to make the lives around him better. Named by Senate Concurrent Resolution (SCR) 133, Res. Chapter 243, 9/12/2018.

    The portion of this route from Bridgeport to Route 108 (~ MNO 76.758 to MNO 94.461) was named the "Sonora and Big Meadows Wagon Road" by Senate Bill 289 in 1901. It was also named the "Sonora and Mono Wagon Road" by Resolution Chapter 11 in 1901, and extended by Resolution Chapter 510 in 1919.

    There is a memorial marker at SBD 66.0 (San Bernardino County) in memory of CHP Officer Larry J. Jaramillo. California Highway Patrol Officer Larry J. Jaramillo died in the line of duty in a traffic collision on Route 395 at the Kern County San Bernardino County line, while returning from court in Inyo County on June 22, 1993. Officer Jaramillo joined the Department of the California Highway Patrol in 1985, after successfully completing training at the patrol academy where he received the outstanding athlete award for his class, and, upon graduation, he reported to Morongo Basin, as a state traffic safety officer in December 1985. In 1989, Officer Jaramillo tested and qualified with the department to become a fixed wing pilot and was assigned to the Inland Division Air Operations Unit stationed in Daggett, California. On December 8, 1992, Officer Jaramillo received the second highest award that the department may bestow, the Special Act Award, for his rescue of two young men stranded in the snow-covered mountains of Kern County during which Officer Jaramillo continued his search for the young men despite warnings of adverse weather conditions, endangering his life to continue the search until the men were found.

    The portion of this route between Alturas and a point 6 mi W (i.e., between the two US 395/Route 299 junctions) is cosigned as US 395/Route 299, although it is legislatively US 395.

    The segment from the Nevada state line northwest of Reno to Route 36 near Johnstonville (Susanville) was part of LRN 29, and was signed as US 395. It was a 1919 extension of the 1909 LRN 29, which ran as (signed) Route 36 between Red Bluff and Susanville (in 1933, LRN 29 was extended further to run, still as Route 36, between Route 3/Route 36 [LRN 35] to US 99 [LRN 3]).

    The segment from Alturas to the California-Oregon state line near New River was LRN 73, added in 1931. This was also signed as US 395. California Highways and Public Works, April 1931, noted that the justification for the addition what that it established a connection between the Oregon State Highway System and the Redding-Alturas lateral ([LRN 28]) of the California State Highway System. The project was considered a necessary link on an east of the Sierras routing. It was a designated Federal aid route. It had been recommended for inclusion in the State highway system by the Highway Advisory Board in 1925. At the time, Oregon was improving its roads from Klamath Falls, from Bend and from Burns territory (the Yellowstone cut-off) to the state line at New Pine Creek Oregon, with State and Federal funds, and had practically completed a surfaced road from the Columbia River and also from Klamath Falls to New Pine Creek. As of 1931, the unimproved condition of the California extension was withholding from the public the potential value of these routes. Within California the project will coordinate with the Redding-Alturas highway, and through the Alturas-Susanville route, with the Red Bluff - Susanville - Reno lateral [LRN 29]. There was also a contemplated connection from Lake Almanor to the Feather River road that would extend recreational traffic further south. The route qualified as an interstate connection, as the 1931 California Highway system lacked a connection to eastern Oregon.

    The last segment addition occured in 1933, and was the segment between Susanville and Alturas (more formally, between LRN 29 (Route 36/US 395) and LRN 28 (Route 299)).

    Status Status

    Currently built to expressway standards for a stretch of 8 miles between the Nevada Border and Route 70.

    At the end of May 2017, it was reported that Caltrans Dictrict 2 is developing a 20-year plan to make improvements to US 395. This process started by hosting workshops —four are planned—in cities along the road—seeking citizens’ comments. Caltrans even went so far as to bring homemade brownies (something that is above and beyond!). The workshop in Alturas was attended by 15 local residents—including elected and agency officials—was chockfull of happily-relayed comments as the group studied the road, north from near Susanville to New Pine Creek, at the California-Oregon border. In the workshop, three basic questions were asked: What works well? What works not-so-well? How can it be improved? Among improvements needed, according to the locals are:

    • Consistent width to the roadway in parts north of Alturas. The road widens and constricts and widens again, without notice, and this is a hazard for motorists.
    • More web-accessible cameras to show highway conditions—especially at the higher elevation mountain passes like Sugar Hill north of Davis Creek, and Sage Hen Summit, south of Likely.
    • Signs that denote what services are available and where.
    • The old-fashion “cinders” used on icy spots—rather than whatever Caltrans is using nowadays.
    • Rest stops with bathrooms that have water—not the smelly “vault” toilets—and are open year-round. There is only one rest stop in 203 miles—chemical toilets located on a downgrade that’s not very safe, participants said.
    • Warnings for motorists that they are passing through “open range”—where the cows have the right-of-way. “People hit them and have died,” noted one participant.
    • Signs that indicate where people can access the rail trail—the alignment of the NCO Railroad from Susanville to near Likely that has been turned into recreation asset.
    • In Alturas, 25 MPH signs through downtown, as traffic has a tendency forget the speed limit.
    • Red zones at downtown Alturas intersections so it’s easier for cross traffic to see oncoming autos on the highway.
    • More pedestrian-activated crossing signals and well-marked crosswalks. These could even be solar powered as in other parts of the state.

    One little bit of information eeked out—from a participant and was augmented by Caltrans staff: There is a longstanding plan to transform the US 395 alignment from the Arizona-Mexico border to the Washington-Canada border into a super highway akin to I-5. It even has a name: I–11. “Not going to happen in our lifetime,” was the general consensus from the group. Still, the idea of a full-bore interstate knifing through Eastern California creates wild surmise, and the Caltrans representative will include a notation about I–11 that “the proposal is out there” in the new report being created.

    Sierra / Lassen Widening

    In March 2016, the CTC authorized additional funding on US 395 in Sierra and Lassen Counties, from Nevada State line (apx 395 SIE R0.0L) to one mile north of Route 70 (395 LAS R5.215). Rehabilitate pavement. This project is located in a remote location and requires significant lab and materials support. A structures maintenance review identified bridgework that was not originally in the scope, which requires additional lab support and services. In addition, there is increased support needed for the superpaving methodology. This increase is consistent with the required work for a CAPM and adds $412,000 to the cost of the project.

    In August 2016, the CTC approved $11,512,000 in funding for US 395 in Sierra (PM R0.0/R3.1) and Lassen (PM R0.0/5.6) Counties, from Nevada State line to 1 mile north of Route 70; also, on Route 70 from PM 3.5 to 3.9. Outcome/Output: Rehabilitate 34.2 lane miles of pavement to extend pavement service life and improve ride quality. Project will overlay pavement, upgrade nine culverts, install approach slabs at eight locations, rehabilitate four bridges with polyester concrete overlay, install one intelligent transportation system (ITS) monitoring device, and make ADA and drainage improvements at the Agriculture Inspection Station.

    In October 2017, the CTC authorized vacation of right of way in the county of Lassen along Route 395, between Janesville Grade and Lake Crest Road (02-Las-395-PM 52.3/52.6), consisting of stock trail easements no longer needed for State highway purposes.

    In March 2013, the CTC provided advance authorization for $2,995,000 to rehabilitate 12.0 lane miles of roadway to improve the ride quality, prevent further deterioration of the road surface, minimize the costly roadway repairs and extend the pavement service life on the segment in and near Johnstonville, from 0.1 mile north of Sunnyside Road (apx 395 LAS 56.437) to 0.3 mile south of Route 36 (apx 395 LAS R60.693).

    In May 2008, the CTC considered relinquishment of right of way in the city of Alturas, at Court Street (apx 395 MOD 22.884), East Street, East A Street, and East B Street, consisting of reconstructed and relocated city streets.

    Naming Naming

    The portion of US 395 from the South Fork Pit River Bridge to a portion of the Modoc National Wildlife Refuge (~ MOD 16.523 to MOD 20.000) in the County of Modoc is named the "Deputy Sheriff Jack Hopkins Memorial Highway". It was named in memory of Deputy Sheriff Jack Hopkins, who was born in Livermore, California, in August 1985, and was named after his grandfather, Jack L. Hopkins, who was the first mayor of Rolling Hills Estates, California. Hopkins was raised on a cattle ranch in the rural Shasta Valley and baptized in the Shasta River. Jack Hopkins attended Grenada and Big Springs Elementary schools and graduated from Yreka High School in 2004. Hopkins, who learned a great deal of discipline and respect from Mitch Klier, of Klier’s Martial Arts, earned a black belt in karate and won a world championship karate title in 2001. Hopkins went on to pursue multiple associate of arts degrees at Butte College, then returned to Butte College to attend the police academy with his older brother, Officer Sam Hopkins, and graduated in 2013. Hopkins was known for being the type of person whose handshake was his “word,” a happy, good-natured guy with a great personality, and a big smile who laughed often. Jack Hopkins began his law enforcement career with the Alturas Police Department and transferred to the Modoc County Sheriff’s Office. Jack Hopkins was killed in the line of duty on October 19, 2016.

Historical Route Historical Route

As of March 2008, the California Transportation Committee unanimously approved the designation of former US 395 as a historic route from San Diego to the Oregon border. It is still pending approval by the legislature and the governor. However, anticipating approval, San Diego County Supervisor Bill Horn approved $4,000 for the 31 signs that now mark old 395 in his district -- from Vista to the Bonsall Bridge, through downtown Fallbrook, to Rainbow.

On July 8, 2008, Resolution Chapter 79 officially designated specified sections of former US Highway Route 395 as Historic US Highway 395. The resolution noted that former US 395 was a scenic stretch of highway that ran through historic areas of the County of Riverside and provided the only direct route from San Diego to the Lake Tahoe region and northern Nevada, before heading back into California on its way north to Oregon and all the way into Canada. While former US 395 remains largely intact through the Counties of Inyo, Mono, Sierra, Lassen, and Modoc, only sections of former US 395 still exist in portions of the County of San Diego and the high desert area of the County of San Bernardino; most of the former highway route has been replaced by I-15 and I-215 in the Counties of San Diego, Riverside, and San Bernardino. US 395, which remains as I-15 and I-215, was the major and most significant connection between San Diego, the Inland Empire, and the eastern Sierra Nevada region. US 395 was known as the Cabrillo Parkway (and later the Cabrillo Freeway) in San Diego, now Route 163, it was the first freeway to be constructed in San Diego and opened to traffic in 1948. Part of the original routing of former US 395 in northern San Diego County includes the old Bonsall Bridge, one of the earliest automotive crossings over the San Luis Rey River, later becoming part of Route 76. The portion of former US 395 between Temecula and Lake Elsinore was part of the Butterfield Overland Mail route, the first major overland delivery service to southern California, established September 16, 1858. After its realignment eastward, former US 395 became the first major expressway and freeway system in the southern portion of the County of Riverside in the early 1950s, servicing the Cities of Temecula, Murrieta, Menifee, Sun City, and Perris. Today this is I-215. The portion of former US 395 between the Cities of San Bernardino and Hesperia, near modern US 395, traverses the Cajon Pass with old US 66 and old US 91, most famously used by the Mormons in 1851 in their crossing into the valley where they subsequently founded the modern Cities of San Bernardino and Riverside. The heritage in the regions through which former US 395 passed was greatly diminished when the former highway was replaced by suburban streets and I-15 and I-215.The Legislature hereby recognizes the remaining segments of US 395 for their historical significance and importance in the development of California, and designates those segments as Historic State Highway Route 395. Named by Assembly Concurrent Resolution (ACR) 98, Resolution Chapter 79, on 7/3/2008.

In January 2016, it was noted that more cities were signing historic US 395. Moreno Valley will be the latest Inland city, joining others from Riverside to Temecula, to rediscover the US 395 and put up brown signs along the route of the once-vital artery. The city and Moreno Valley Historical Society dedicated the 2-mile section of the 395 between Eucalyptus and Cactus avenues on Memorial Day with a weekend of activities. Though US 66, another U.S. highway, is considered the mother road connecting the nation east to west, the 395 is its lesser-known north-south counterpart. The 1,400-mile road was known as the Three Flag Highway because it went from the Mexican border through several Western states to the Canadian border, said Jeffery Harmon, founder of the Historic Route 395 Association. It was officially designated U.S. Highway 395 in 1939 after passage of federal legislation. However, it had existed as a series of dirt roads from San Diego to the Cajon Pass for decades. During World War II, at the urging of the military, the highway was improved to provide a better link between San Diego’s Navy base, a weapons depot in Fallbrook and March Field in what later became Moreno Valley. The route was nicknamed the Cannonball Highway because of its military importance. The highway faded into obscurity after years of rerouting and the development of other north-south routes, I-15 and I-15E (now I-215), in the 1970s. By the 1980s, US 395 had been decommissioned in Riverside and San Diego counties, though it continues to run from Hesperia in San Bernardino County along the eastern Sierra Nevada and north to Canada. In recent years, several cities have begun efforts to commemorate US 395. In San Diego and other cities in San Diego County, signs were put up along the route. Communities such as Fallbrook, Rainbow, Temecula, Murrieta, Lake Elsinore, Perris and Riverside did the same. In Riverside, city officials put up 36 signs on downtown streets, including Market Street and University Avenue, which still has roadside hotels that are a remnant of when it was part of the highway, said Steve Lech, president of the Riverside Historical Society.

Pre 1964 Signage History Pre 1964 Signage History

Until July 1, 1964, the following route was signed as US 399:

  1. Present-day Route 33 between US 101 [LRN 2] in Ventura and Route 166 (LRN 57) 7 mi N of Ventucopa. This segment was LRN 138, defined in 1933.

  2. Present-day Route 33/Route 166 (previously cosigned as US 399/Route 166) between 7 mi N of Ventucopa and Maricopa. This segment was LRN 57, defined in 1919.

  3. Present-day Route 33 between Maricoa and Taft (previously cosigned as US 399/Route 33). This was LRN 138, defined in 1933.

  4. Present-day Route 119 between Taft and US 99 (present-day Route 99). This was LRN 140, defined in 1933.

Signage of the route as US 399 dates back to around 1935. Note that, as of 1936, US 399 actually continue north cosigned with US 99 to end at US 466. This portion of US 399 was later relegated to Business Loop status in 1962, and became Business Route 99/Route 204 in 1964. However, the portion of former US 399 south of Brundage Lane (current parallel street to Route 58, the replacement for US 466) was removed from the state route in 1978; only the portion of former US 99 on Union Avenue from Golden State Avenue/Sumner Street south to Route 58 remains in the state system as Route 204. All of the route remains part of Business Route 99.

This segment remains as defined in 1963.

The first section of I-405 opened in 1957, signed as Route 7. One of the earliest sections was in West Los Angeles, from Bellagio Rd to Santa Monica Blvd. The part west of I-605 was done before 1965; the newest section, near the southern junction with I-5, opened in 1969.

The following freeway-to-freeway connections were never constructed:

Pre 1964 Signage History Pre 1964 Signage History

This routing was LRN 158. The portion from I-5 in Orange County to Route 710 was defined in 1951; the portion from Route 710 to Route 90 was defined in 1947; and the portion from Route 90 to I-5 in San Fernando was defined in 1933.

Before the freeway was constructed, LRN 158 also applied to pre-1963 Route 7 between Route 107 and the US 99/US 6 junction.

Rte 405 (Rte 7) at Rte 101Sparker on AAroads provided some interesting history on the route: "The initial construction on I-405 actually started shortly before the Interstate era as a freeway upgrade to then Route 7 (LRN 158) between Culver City and the Santa Monica Mountains; that segment opened to traffic at the end of 1957 with Route 7 signage; that was replaced by that summer with I-405 signage. But by that time the only sections of the proposed route in L.A. County that were not already seeing large-scale development were the section over the Santa Monica mountains (a situation remedied by today) and the segment between the Long Beach (current I-710) and Harbor (again, now I-110) freeways, which was in the '50's largely occupied as "tank farms" by several oil companies (Getty Oil owned a large portion of what is now the city of Carson). Otherwise, by 1955 the sections from Gardena north to West L.A. were occupied by housing -- although since that alignment had been adopted by '56, only a few early tracts in Lawndale and Torrance had to be razed to accommodate the freeway; a ROW had been reserved for the remainder. The same applied to North Long Beach, but as an older residential area, more developed property had to be obtained for the freeway. Only in Fountain Valley within O.C., and what is now Irvine southeast of Route 55, was there considerable open/undeveloped land (the latter owned by the Irvine Company, a family business). I-405 was always considered an "alternative" rather than a classic "bypass" by the Division of Highways and later Caltrans, as it served one of the major California cities (Long Beach) as well as several other coastal regional centers (Torrance, Redondo Beach) from which I-5 remained at a distance."
(Source: Sparker on AAroads, "Re: I-405 widening in Orange County has started", 1/24/2019)

The I-405/I-605 interchange was designed by Carol Schumaker.

[Reece at 405-10]The I-405/I-10 interchange was designed by Marilyn Jorgenson Reece, who was the first woman in California to be registered as a civil engineer. She died in May 2004. A South Dakota native who earned a bachelor's degree in civil engineering from the University of Minnesota in 1948, Reece moved to Los Angeles with her parents shortly after graduation. The same year, she went to work for the State Division of Highways, which later became Caltrans, as a junior civil engineer in Los Angeles. In 1954, after six years of required experience to sit for the Professional Engineer's Exam, Reece became the state's first fully licensed female civil engineer. In 1962, she received the Governor's Design Excellence Award from Gov. Pat Brown for the San Diego-Santa Monica freeway interchange. Shortly after, Reece became the Division of Highway's first woman resident engineer for construction projects. The three-level San Diego-Santa Monica freeway interchange, which opened in 1964, was the first interchange designed in California by a woman engineer. Reece told The Los Angeles Times in 1995 that she put her "heart and soul into it" and that she designed the interchange with aesthetics in mind. "It is very airy. It isn't a cluttered, loopy thing," she said, adding that specifications to keep traffic moving at high speeds necessitated the long, sweeping curves. The image to the right, excerpted from One Hundred Years of Progress, shows Reece and Thomas McKinley. However, the book referred to Reece as an Associate Engineer, with McKinley as a Resident Engineer, but did indicate that Reece supervised the I-405/I-10 interchange project. The view in the photo is looking N from what is roughly the National offramp on the I-405; you can see a sign for the Route 26 Olympic Blvd NB offramp that was removed as part of the project (likewise, the SB National offramp was removed). A nice profile of Ms. Reece may be found on the LA Daily Mirror blog. She is also profiled in the Transportation History blog.

In the improvement of the San Diego Freeway through the Veterans Administration Center, it was necessary to acquire property in the name of the County of Los Angeles for the realignment of Wilshire Boulevard and for the widening of Federal Avenue, the reconstruction of which has been carried out by the State Division of Highways. The necessary grants of property from the Federal Government were secured under the provisions of Section 17 of the Federal Highway Act of November 9, 1921, as amended, 42 Statutes 216. The Federal Government transferred a total of 54.2 acres of which 46.6 acres was to the State of California for the San Diego Freeway, and 7.6 acres was to County of Los Angeles for the improvement of Wilshire Boulevard and Federal Avenue. The State and county received from the Federal Government for this project land worth well in excess of $2,000,000. The State, in return, has carried out considerable construction and relocation work for the benefit of the veterans' facility. The grant to the County of Los Angeles provided for the vacation of San Vicente Boulevard by the County of Los Angeles through the Veterans Administration Center whereby 6.6 acres would be added to the usable area of the veterans' facility.

As for Sepulveda Canyon, Sepulveda Blvd, and I-405: For centuries the region’s native Tongva people had hiked a faint footpath through Sepulveda Canyon, and in 1769 the soldiers and clergy of Spain’s Portola expedition followed that ancient trade route on their way to Monterey. Trail became road in 1875, when the two wheat barons of the San Fernando Valley, Isaac Lankershim and Isaac Newton Van Nuys, widened the footpath to allow for the passage of sturdy wagons laden with grain and bound for ships docked at the Santa Monica Pier. But when the Southern Pacific soon lowered its freight rates, the wheat ranchers instead sent their harvest by train to San Pedro. The new, neglected road eroded into the hillsides. Development in the San Fernando Valley during the 1920s persuaded the city and county to rebuild the road for automobiles. Traffic was overwhelming the two established routes between the Valley and the Basin, Cahuenga Pass and San Fernando Road, both of which were out of the way for residents of faraway Van Nuys and Owensmouth. New Sepulveda Boulevard – a 50-mile highway stretching between San Fernando and Long Beach – would provide the Valley with a more direct link to the Basin and harbor beyond at San Pedro Bay. Construction lasted several years and culminated with the opening of a 650-foot tunnel beneath the summit at Mulholland Drive, an event the city celebrated with a grand Spanish-style fiesta. Despite the festivities, by the time traffic started flowing in September 1930, the new Sepulveda Canyon Road was already inadequate. Five years later the state spent $275,000 to pave it, and by the late 1950s traffic engineers developed a new construction project that just might keep traffic flowing freely over Sepulveda Pass: Tear Sepulveda Canyon apart and then rebuild it to allow a superhighway to pass through. Beginning in August 1960, earthmovers carved a gorge 1,800 feet wide and 260 feet deep through the mountains, accomplishing in two years what might take natural erosional forces two million. The bulldozers' total haul: 13 million cubic yards of slate, shale, and dirt. Workers then built massive retaining walls to keep the unnaturally steep slopes from slipping and reconfigured the area's natural drainage through a series of culverts. By 1962, an eight-lane concrete freeway with a maximum grade of 5½% sliced through the mountains.

Construction on I-405 (the "Sepulveda Freeway") in West Los Angeles begin in 1954. CHPW noted in November-December 1953, "Los Angeles County, structures on the route of the Sepulveda Freeway, between Waterford Street and Casiano Road in West Los Angeles, $800,000 (first construction on the Sepulveda Freeway)." Construction started with the original bridges at Sunset Blvd. The name San Diego Freeway started being used in 1955. The first segment of I-405 opened was the two-mile section of the San Diego Freeway from Ohio Street to Casiano Road. The first plan work on the San Diego Freeway was started by the Engineering Bureau Department of Public Works of the City of Los Angeles under City Engineer Lloyd C. Aldrich in 1939 when it was known as the "Sepulveda Parkway."

Mulholland Construction ImagesA November 2010 briefing on the I-405 HOV construction in the Sepulveda Pass included these wonderful photos of the construction of the original Mulholland Bridge. More photos can be found at the LA Times.

A Metro article on the same bridge noted that the bridge was completed on April 4, 1960. The main portion of Mulholland Drive—westward from the Cahuenga Pass in Hollywood past the Sepulveda Pass—opened in 1924 under a different name: the Mulholland Highway. It was built by a consortium of Hollywood Hills landowners. Their goal was to bring development to the Hollywood Hills and make a few dollars for themselves. In May 1958, the State Division of Highways—this preceded the creation of Caltrans—called for bids on a $10-million highway construction project. Besides closing a 4.1-mile gap in US 101 and funding other work on the San Diego Freeway, the 1958 contract required the relocation of 1.1 miles of Mulholland Drive south. Once moved, Mulholland Drive would cross a new 579-foot-long bridge: Mulholland Drive Bridge. When completed, relocating Mulholland Drive and building Mulholland Drive Bridge cost $1,824,000. In June 1960, bids were opened for a $14-million contract to extend the San Diego Freeway 7.4 miles from Brentwood to Valley Vista Bl in the San Fernando Valley. Mulholland Drive Bridge would finally span a freeway. The original bridge was demolished starting in July 2011.

The segment of I-405 between West Los Angeles and the Valley opened to traffic on December 21, 1962. When it happened, San Fernando Valley realtors took out a full page ad in the Santa Monica Evening Outlook heralding the effect in travel savings and increased accessibility between the valley communities and West LA. Public response to the new freeway was instantaneous as 82,000 motor vehicles diverted from parallel mountain roads to the new facility in the first full day of operation. The Average Daily Traffic on Sepulveda Blvd dropped from 42,000 to 3,000! Peak travel time was cut in half, from 14 minutes to 7 minutes (and many people in 2013 would be ecstatic about a travel time of 15 minutes for the pass!).

According to the LA Times, I-405 in the Sepulveda Pass was a bypass for Sepulveda Boulevard (former Route 7), opened in 1935 and was hailed in the Los Angeles Times as a "new and wondrous highway" over the mountains, vastly superior to the overcrowded Cahuenga Pass and Laurel Canyon. The pre-405 Sepulveda Blvd consisted of numerous hairpin curves, which claimed 65 lives during the 1950s alone. More than 40,000 vehicles a day passed through the tunnel under Mulholland Blvd. Northbound traffic routinely backed up to Sunset Boulevard. The Sepulveda Pass project begin in August 1960. Statistics on the project included: Eighteen million cubic yards of earth removed! Ninety thousand cubic yards of concrete poured! Six million pounds of steel holding it together! A 30-story building could be hidden within the depths of the so-called Big Cut. It was opened on December 21, 1962.

Pictures of the construction of I-405 in the San Fernando Valley may be found here. An article on the geology of the Sepulveda Pass may be found here.

In November 2015, Curbed LA reported on a proposal by the Libertarian-leaning Reason Foundation to construct a bypass tunnels from I-10 to US 101. There were three options: From Route 1 to US 101 roughly along Reseda (roughly the unbuilt portion of Route 14, but with a terminus at I-10/Route 1), under I-405, or from the termination of Route 187 (Venice) to Laurel Canyon (roughly the unbuilt southern portion of Route 170). The ideal route Reason offers would travel from Santa Monica, underneath Topanga State Park, to Tarzana. If they have trouble tunneling through a state park land (spoiler alert: they will), there are two alternatives—one tunnels under the 405 (note that a tunnel here is also part of Measure M under consideration in 2016) and the other under Laurel Canyon. If built, a six-lane tunnel would carry an estimated 109,000 cars per day to and from the valley, producing $9.7 billion in revenue over 40 years. CurbedLA noted, regarding this proposal, "They're cute plans, but only a fool would run this bureaucratic marathon for a transit plan that looks backwards to cars instead of forwards to mass transit and fossil-fuel-free options." The estimated cost for all their tunnels would be $700 billion.
(Sources: CurbedLA, 11/17/2015; AARoads Forum, Subject; "What about a tunnel from the end of Glendale Freeway to Interstate 110?")

Both sections in the San Fernando Valley (from Burbank to Nordhoff, and from Nordhoff to I-5) opened to traffic on April 19, 1963.

New Newhall RoutingInteresting historical note: In the May/June 1928 issue of California Highways and Public Works, there is a discussion of the routing of the Newhall Highway from Saugus to San Fernando. The article notes: "From a point on the south roadway near the Cascades it is proposed to extend a new highway south through the San Fernando Valley and the Santa Monica mountains to the west coast; there to connect with the state coast highway extending from Oxnard to San Juan Capestrano"

South Orange County Lane Addition (12-Ora-405, PM 0.2/8.7)

In October 2018, the CTC approved for future consideration of funding the following project for which a Mitigated Negative Declaration (MND) has been completed: I-405 in Orange County (12-Ora-405, PM 0.2/8.7). Construct roadway improvements including the addition of one lane on a portion of I-405 near the cities of Costa Mesa and Irvine. (MPO ORA13104). This project is located on I-405 near the cities of Costa Mesa and Irvine in Orange County. The project proposes to add a single general lane on the mainline freeway and interchanges on I-405 in both directions from I-5 to Route 55. The project proposes to improve the high level of congestion on the existing I-405 corridor and on-off ramps and the current inadequate Intelligent Transportation System (ITS) infrastructure. The proposed project addresses the existing and future traffic demand and provides future mobility while minimizing environmental and economic impacts. The proposed project is currently programmed and funded through the Project Approval and Environmental Document (PA&ED) phase for $8.0 million (Surface Transportation Block Grant funds) in the 2017 Federal Transportation Improvement Program. The estimated schedule for construction is yet to be determined pending additional funding for the proposed project.
(October 2018 CTC Agenda Item 2.2c.(1))

In January 2016, the CTC approved SHOPP funding on I-405 in Irvine, Fountain Valley and Seal Beach at Route 133, Brookhurst Street, Warner Avenue, and Seal Beach Boulevard (~ORA 1.758, ORA 13.784, ORA 14.871, and ORA 22.618). Outcome/Output: Widen ramp, overlay connector and ramps with open graded hot mix asphalt, upgrade guardrail and install lighting to reduce the number and severity of collisions. $1,313,000

Sand Canyon Auxiliary Lanes (~ ORA 1.758 to ORA 3.93)

There are plans to add auxiliary lanes from Sand Canyon Road on-ramp to Jeffrey Road (~ ORA 2.887 to ORA 3.907), and from Route 133 to Sand Canyon Road (~ ORA 1.758 to ORA 2.887). July 2005 CTC Agenda.

In May 2013, the CTC received notice that the OCTA would propose delaying the environmental phase of the Route 405 Southbound Auxiliary Lane – Sand Canyon to University project (~ ORA 2.887 to ORA 3.93) to FY 2014-15 in order to align the project with the schedule of an adjacent Route 405 southbound auxiliary lane project. In June 2013, the CTC approved delaying $224,000 in RIP PA&ED from FY 2013-14 to FY 2014-15 for the Route 405 Southbound Auxiliary Lane – University to Sand Canyon project (PPNO 4956) in Orange County.

In August 2014, the CTC authorized $528K for construction of an auxiliary lane on I-405 from University to Route 133 southbound.

The 2018 STIP, approved at the CTC March 2018 meeting, appears to close out PPNO 4956 Auxiliary lane southbound, University-Rt 133, env/PSE.

The following project was included in the final adopted 2018 SHOPP in March 2018: PPNO 4956A. 12-Orange-405 2.4/3.9. On I-405, In Irvine, from Route 133 to Sand Canyon Avenue; also from Sand Canyon Avenue to University Drive/Jeffery Road. Construct southbound auxiliary lanes. Begin Con: 12/1/2019. Total Project Cost: $8,200K.

In April 2019, Caltrans published a commuter alert on the start of construction for this project. The alert noted that construction was expected to be completed in January 2020.

As originally constructed, there were problems with the new HOV connector ramps between I-405 and Route 55 (~ ORA 8.207). It seemed that the bridge had cracks so severe that the bridge might not be able to handle the weight of daily traffic. The estimated repair costs would be 80% of construction costs for this bridge. The bridge was eventually repaired and reopened.

In August 2016, it was reported that Caltrans plans to close Red Hill Avenue (~ ORA 8.432) to all traffic between Pullman Street in Costa Mesa and Main Street in Irvine starting at Aug. 29. The bridge is part of that stretch. It is being shut down for four months of repairs to stabilize the embankment under one of the approach ramps. The roadway is expected to remain closed until Dec. 30. The closure is necessary because the earth under the approach ramp on the Costa Mesa side is moving, which has caused walls meant to keep the soil in place to bulge slightly and "triggered progressive pavement cracks on the roadway above," according to Caltrans. As part of the $9.5-million project, the underlying soil embankment will be reinforced and new retaining walls will be constructed.

Route 405 Widening - Route 55 to I-605 (Initial Construction) (~ ORA 8.901 to ORA 24.164)

The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures for this route:

In June 2007, the OCTA outlined a 5-year plan for the use of the 2nd Measure M funds that included adding lanes on Route 91 between I-5 and Route 57 and between Route 55 and the Riverside County border; adding lanes on I-405 between Route 55 and I-605 (~ ORA 8.901 to ORA 24.164); a new NB lane on Route 57 between Orangewood Avenue and Lambert Road.

HOT Lanes - Orange County (Rte 73 to I-605, ~ ORA 10.352 to ORA 24.164)

In February 2010, the Daily Pilot reported that the Orange County Transportation Authority approved further environmental and engineering study of a proposal to add high-occupancy toll (H.O.T.) lanes to I-405 in Orange County between Route 73 and I-605. Specifically, the proposal proposes to add one general-purpose lane and one H.O.T. lane in each direction on I-405 between Route 73 and I-605 freeways. There is already one high-occupancy vehicle lane in each direction that would be converted into a H.O.T. lane, so it would create a total of two express H.O.T. lanes in each direction. About $600 million in funding for the expansion is available from Measure M2 – a ½¢ county sales tax that pays for transportation improvements – but that is far less than is needed for even the most modest expansion currently being considered. The cheapest option being explored is to add one general-purpose lane in each direction, which would cost $1.7 billion but would generate no revenue. The most expensive is to add two express lanes in each direction and charge tolls, which would cost $2.2 billion but would generate $197 million annually – enough to support the full cost of the project. The freeway expansion is tentatively slated to begin in 2016.
[Source: "OCTA approves study of 405 widening project", Daily Pilot, 2/10/2010]

In June 2012, there were public hearings on the plans to widen I-405 between Route 73 and I-605. Caltrans and the Orange County Transportation Authority are looking at three alternatives for the San Diego Freeway, between the Corona del Mar (Route 73) and the San Gabriel River (I-605) freeways. The first option is to widen the I-405 by adding a single general-purpose lane in each direction from Euclid Street to I-605. The second option would do the same thing as the first and also add a general-purpose lane in the northbound direction from Brookhurst Street to the Seventh Street exit on Route 22 and a second general-purpose lane southbound from Seal Beach Boulevard to Brookhurst. The third option would add one regular lane in each direction of I-405 from Euclid Street to the I-605 interchange and a tolled express in each direction from Route 73 to I-605. There also is a no-build alternative. The third option has received an icy reception in Costa Mesa and Westminster. Seal Beach doesn't want either the second or third options because both would move a sound wall closer to the College Park East community. And in Fountain Valley, some officials are concerned because of the impact on local businesses. Under the third option, two toll lanes from Route 73 to I-605 would be free to cars with three passengers most of the time, but there would be a charge during peak hours. Cars with just a driver or two people would be charged. A decision is in Summer 2012. Construction is scheduled to begin in 2015 and could last roughly 4½ years. The cost of the project ranges from $1.3 billion to $1.7 billion, depending on which alternative is chosen.
(Source: OC Register, 6/13/12)

405 Orange CountyIn August 2012, the CTC reviewed a draft EIR for this project, and indicated that there were no comments to the Draft EIR, that the Findings were accepted and that consideration of funding should be brought forward to the Commission for approval of Design Build funds. The Draft EIR proposed the following alternatives: (0) No Build Alternative; (1) Alternative 1 would add one general purpose lane; (2) Alternative 2 would add two general purpose lanes; and (3) Alternative 3 would add one general purpose lane and one Express Toll Lane. The Toll Express Lane and the existing High Occupancy Vehicle Lane would be managed jointly as a tolled Express Lanes Facility with two lanes in each direction.

In September (and again in October) 2012, the OCTA voted against HOT lanes for I-405 in Orange County. The OCTA did approve a $1.3 billion plan that adds one lane in each direction from Euclid Avenue to I-605. The project will be fully funded by Measure M, a half-cent sales tax voters approved in 2006. The board could not gather the votes in favor of the toll system because too many questions remained regarding how the anticipated toll revenue – about $1.5 billion generated over 20 years – would be used. Under the vetoed toll option, existing carpool lanes would be used to create toll express lanes between Route 73 and I-605. That alternative also included adding one general-purpose lane in each direction. In early 2013, the California Department of Transportation will look at three options. The first adds one general-purpose lane in each direction. Cost: $1.3 billion. The second adds two general-purpose lanes each way. Cost: $1.4 billion. A third option adds one general-purpose lane in each direction and a toll lane to the existing carpool lane that will be managed together. Cost: $1.7 billion. OCTA is working closely with Caltrans and anticipates they will concur with the board's selection of alternative 1.

In January 2013, it was reported that several cities along the I-405 corridor in south Orange County want more widening than the OCTA approved. They favor a proposal that would add two lanes in each direction, not just one, at a cost of around $1.4 billion. Voters in 2006 approved the idea of adding one lane in each direction as part of a package of transportation projects paid for with a half-percent sales tax, known as Measure M2. Planners later raised two other possibilities. The first would add two lanes in each direction. The other would add one normal lane and create two pay-to-ride toll lanes in each direction, in part by using existing carpool lanes. That last option drew immediate fire from cities along I-405. Six of them – Costa Mesa, Huntington Beach, Westminster, Fountain Valley, Seal Beach and Los Alamitos – launched a $25,000 lobbying effort to derail the toll lanes and push for two new lanes in each direction. They're considering whether to pool another $25,000 to keep the fight going. The $1.4 billion cost to add two lanes in each direction may seem like a short jump from the $1.3 billion estimate for single lanes, but that's a difference of $100 million. Those who support the double-lane solution say the money could be found in other projects. The OCTA board, though, voted 12-4 last fall to support the less-expensive single-lane project.
(Source: Orange County Register, 1/25/13)

In December 2013, the OCTA approved adding a new lane in each direction of I-405 between the LA County Line and Costa Mesa. No toll lanes.

In July 2014, it was reported that Caltrans is moving forward with a controversial plan to add toll lanes to I-405 in Orange County despite strong opposition from nearby cities. The Caltrans plan incorporates some of the OCTA proposal, but generated opposition because it adds the toll component and overtakes an existing carpool lane to create the two HOT lanes in each direction. Caltrans is exploring the possibility of allowing vehicles with two or more occupants to ride free in the toll lanes, but a final decision has not been made. Under the plan, Orange County transit officials would continue with their project adding a free lane on each side of the 405. When that work is done, Caltrans plans to build a second new lane on each side. These new lanes, plus two existing carpool lanes, would then be coverted to HOT lanes for use by solo drivings willing to pay as well as carpoolers with multiple passengers.
(Source: Los Angeles Times, 7/25/14)

In June 2015, it was reported that Caltrans District 12 signed the Record of Decision sealing the selection of an improvement project for the I-405 Freeway through Orange County. Caltrans has chosen an alternative that adds a general purpose lane to I-405 in each direction from Euclid Street in Fountain Valley to the I-605 interchange. It also adds a toll lane in each direction between Route 73 and eastbound Route 22 in Westminster. It also will take the existing carpool lane in each direction and add it to the tolled Express Lane. The Record of Decision identifies five intersections in Long Beach with significant impacts from the expansion. The percentage of cost OCTA is willing to pay for improvements ranges from 8% to 23%.In April 2014, it was reported that Orange County transportation officials caved, indicating couldn't fight the state any longer and had to allow toll lanes as part of a $1.7 billion expansion project of I-405. The board voted 12-4 to move forward with a 14-mile project to widen I-405 between Long Beach and Costa Mesa by adding one regular lane and one toll lane in each direction. It also calls for converting the existing carpool lane into a toll lane. Caltrans will provide $82 million to subsidize the $400 million price tag for the toll lanes. The move mirrors decisions by transportation officials in Los Angeles a few years ago, when they caved in to state officials and added toll lanes to I-110 and then the I-10 the following year. Under the project, cars with at least two people will be allowed to use the toll lanes for free for at least three years. The I-405 construction project will run from Route 73 in Costa Mesa to I-605 near the Long Beach/Los Angeles County border. Construction should begin in 2018; it is expected to take five years to complete. By the year 2040, the expansion is estimated to shrink commute times in the free lanes between the two areas from 57 minutes to 29 minutes.

In May 2015, it was reported that the director of Caltrans District 12 had signed the Record of Decision sealing the selection of an improvement project for the I-405 Freeway through Orange County. Caltrans has chosen an alternative that adds a general purpose lane to I-405 in each direction from Euclid Street in Fountain Valley to the I-605 interchange. It also adds a toll lane in each direction between Route 73 and eastbound Route 22 in Westminster. It also will take the existing carpool lane in each direction and add it to the tolled Express Lane. Long Beach has fought the project because the freeway expansion stops at the city’s border, creating a potential bottleneck. Orange County Transportation Authority officials have argued that the beginning of I-605 at the county line mitigates the larger I-405 feeding into the area. The Record of Decision acknowledges Long Beach’s concerns, but says they have been answered in previous responses. In regards to ongoing negotiations between Long Beach, OCTA and Caltrans regarding mitigation payments for repair and upgrades of Long Beach city streets near the freeway, the document says, “It is anticipated this discussion would conclude prior to the start of project construction with an agreement. Caltrans and OCTA are committed to payment of the fair share identified in the Final EIR/EIS.” That document identifies five intersections in Long Beach with significant impacts from the expansion. However, the percentage of cost OCTA is willing to pay for improvements ranges from 8% to 23% — an amount Long Beach officials have said is inadequate.

In August 2015, the CTC approved for future consideration of funding a project in Orange and Los Angeles Counties that will construct improvements on the mainline freeway and interchanges on I-405 between Route 73 and I-605. The project is fully funded. The total estimated cost is $1,782,050,000 for capital and support. The project is programmed in the 2014 State Highway Operation and Protection Program for $82,050,000. The balance is funded with federal and local dollars. Construction is estimated to begin in Fiscal Year 2016-17. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2014 State Highway Operation and Protection Program. The EIR claims that project effects on the community have been mitigated to the maximum extent predictable but increased urbanization subsequent to the completion of the project and the temporary construction related effects are considered significant and unavoidable. They claim mitigations have been incorporated to address those issues.

In November 2015, it was reported that the OCTA Board approved the short-listing of four design-build teams (OC 405 Partners, Orange County Corridor Constructors, Shimmick/Tutor-Perini, and Skanska-Flatiron) for the design and construction of the I-405 Improvement Project. The development of the short list is the first of a two-part process recommended under Assembly Bill (AB) 401, which grants design-build authority to agencies like OCTA. During the second step, the short-listed teams will provide feedback on the final request for proposal as part of an industry review that will assist OCTA in evaluating project risks and cost drivers. Each team will submit a technical and financial proposal, and OCTA will choose one contractor based on its findings. The I-405 Improvement Project will add one general purpose lane in each direction from Euclid Street to I-605 and add an express lane in each direction. The new express lane, along with the existing high-occupancy vehicle lane, would become dual express toll lanes in each direction on I-405 from Route 73 to I-605.

In March 2016, it was reported that the OCTA Board of Directors voted on March 14, 2016 to enter into cooperative agreements with the cities of Costa Mesa, Fountain Valley, Huntington Beach, and Westminster to provide city services required during the design-build implementation of the Interstate 405 (I-405) Improvement Project. Because the project includes improvements to city-owned and operated streets and will impact some city traffic facilities, a cooperative agreement with each of the I-405 corridor cities is necessary to define the roles and responsibilities of each agency during the project’s implementation.

In April 2016, it was reported that attorneys for the city of Long Beach and the California Department of Transportation have agreed to litigate the case in a neutral county, San Diego. Long Beach sued the state in summer 2015 over plans to add one toll lane and one free lane to I-405 between Route 73 in Costa Mesa and I-605 near the Los Angeles County line. The proposal also calls for converting the existing carpool lane into a toll lane. Seal Beach also filed a lawsuit against the project. Both cities say they are not against the $1.7 billion freeway expansion itself; instead, they want Caltrans and the Orange County Transportation Authority to pay for more traffic congestion solutions on city surface streets. The California Department of Transportation will provide $82 million to subsidize the $400 million construction price tag for the toll lanes.

In April 2016, it was also reported that initial findings of a traffic and revenue study for express lanes on I-405 – which near the Los Angeles County line is the nation’s most heavily traveled freeway – have been released and Orange County transportation officials will soon determine a toll structure. Stantec, a consultant for the transportation agency, presented board members with a traffic and revenue study outlining three toll options for 14 miles of I-405 between Route 73 and I-605. Tolls could range from an average of about $9 in peak hours to $2 in the off-peak, depending on the toll option for the 14-mile stretch, with lower tolls for shorter trips, according to the study. The study indicated that allowing carpools of at least two people to use the proposed express lanes for free during rush hours – which the OCTA wanted – would not assure a free-flowing commute for customers and could result in tolls of up to $15.46 during peak periods. Options were presented ranged from free or a 50% discount for all vehicles with more than three passengers (HOV+3) to a full toll all the time for all vehicles with two passengers or less (HOV+2). OCTA board members are expected to vote on a toll policy and financing plan for the express lanes May 23. The transportation agency plans to secure financing throughout the summer and enter into an operating toll agreement with Caltrans. Construction is slated to begin in 2017 and run about five years.
(Source: OC Register, 4/27/2016)

In June 2016, it was reported that the OCTA board members had approved the initial 405 Express Lanes toll policy. The approved initial toll policy will allow two-person carpools to remain free in the existing carpool lanes until 2023. After the toll lanes open in 2023, two-person carpools will remain free for the first three and a half years during non-peak hours, pending the results of the project traffic and revenue study. In addition, the California Transportation Commission (CTC) voted unanimously to approve OCTA’s application to develop and operate a high-occupancy toll (HOT) facility for the I-405 Improvement Project, pursuant to Assembly Bill (AB) 194. AB 194 allows regional transportation agencies such as OCTA to apply to the CTC to operate HOT lanes, while ensuring local control. This is the first project approved under this authority. The CTC’s approval will allow OCTA to move forward with the development of the 405 Express Lanes’ operating and enforcement agreements with Caltrans.

In October 2016, the CTC approved a $7,771,000 allocation from the Budget Act of 2016, Budget Act Item 2660-304-6056 for the following locally administered Proposition 1B Trade Corridor Improvement Fund Program project: OCTA 12-Ora-405 9.3/24.2 | I-405 Improvement - Route 73 to I-605. Add one general purpose lane, and one tolled express lane, in both the north and southbound direction; construct eight new structures, rebuild 18 bridges and overcrossings, widen/modify six structures and improve local streets and on/off ramps. (TCIF #122) Design-Build delivery method. (Future Consideration of Funding approved under Resolution E-15-50; August 2015.) (R/W Certification on 9/2/2016.) (The TCIF allocation is split as follows: $0 for construction engineering and $7,771,000 for construction capital.) (Contribution from other sources: $1,537,512,000. $846,000,000) Outcome/Output: The project will reduce traffic congestion, commute time, encourage shared rides and public transit, increase safety and economic productivity, and improve the movement of goods and services. ALLOCATION IS CONTINGENT UPON APPROVAL OF A BUDGET REVISION BY THE DEPARTMENT OF FINANCE.

In November 2016, it was reported that the OCTA board awarded a $1.2 billion design-build contract – the largest in the agency’s history – to add one regular lane in each direction and an express lanes toll facility to relieve traffic on I-405. Upon completion of the I-405 Improvement Project, travel time on the highway from Route 73 to I-605, consistently ranked among the busiest in the nation, is expected to take 29 minutes during rush hour and 13 minutes on the 405 Express Lanes, by the year 2040. OCTA board members, by a 14-0 vote, selected OC 405 Partners – a team of firms led by OHL USA Inc. and Astaldi Construction Corporation – which offered the lowest price for the job of three qualified bidders. This makes the I-405 Improvement Project the first in California that will be built following the passage of AB 401, which allows regional transportation agencies and Caltrans to use a design-build method to deliver highway projects in a way that reduces time and cost. Construction is slated to start in early 2017 with the new regular and express lanes at the center of the highway opening in 2023. The I-405 Express Lanes will also be the first project in California to use the tolling authority provided last year under AB 194 that ensures that any excess toll revenue will be used to fund improvements on local streets and public transportation. In addition to building new lanes, the I-405 project includes constructing 18 bridges and improving access to highway and traffic on surrounding streets.

In February 2017, it was reported that on January 31, 2017, OCTA's CEO, Darrell Johnson, signed a $1.2 billion contract with OC 405 Partners for the design and construction of the I-405 Improvement Project. This is the largest contract in OCTA's history. With this signature, OCTA has issued Notice to Proceed No. 1 to the design-build team, which marks the official beginning of the I-405 Improvement Project. The project is the first in the state being built using the design-build authority provided under Assembly Bill 401 by Assemblyman Tom Daly, passed in 2013. AB 401 provides authority for regional transportation agencies and Caltrans to use the design-build method of project delivery on state highway projects, resulting in cost and time savings. The project, set to begin construction this year, includes adding one regular lane in each direction – as promised in Measure M, Orange County’s half-cent sales tax for transportation improvements – and building the 405 Express Lanes in the center of the freeway. In addition to constructing the new lanes, the project will rebuild 18 bridges and improve freeway access and traffic on local streets.

In August 2017, it was reported that a loan secured by OCTA marks a major milestone in funding the I-405 Improvement Project while saving taxpayers millions of dollars. At the end of July 2017, OCTA signed the final documents with the U.S. Department of Transportation for the $627 million loan through the Transportation Infrastructure Finance and Innovation Act (TIFIA). The TIFIA loan will pay for a major portion of the $1.9 billion worth of freeway improvements set to begin construction early in 2018. The loan’s low 2.91 percent interest rate is expected to save Orange County taxpayers about $300 million over the 35-year life of the loan as compared to traditional bond financing. The loan will be repaid solely using revenue collected from drivers who choose to use the 405 Express Lanes being built as part of the project. In addition, the TIFIA loan will save 405 Express Lanes users up to 20 percent in toll charges, finalizing OCTA’s commitment of allowing vehicles with more than one occupant to initially use the facility for free or at a reduced cost. With the loan secured, OCTA has given the contractor, OC 405 Partners, notice to fully proceed with the design and construction of the project. It’s expected the project will begin construction by early 2018 with completion anticipated for 2023.

In January 2018, it was reported that construction was set to begin on the I-405 Improvement Project (including a formal groundbreaking). With it’s $1.9 billion price tag, the undertaking marks the largest project in the Orange County Transportation Authority’s history, as well as the largest active freeway project in California. The result will be a new freeway lane in each direction, for the 16 miles between Euclid Street in Fountain Valley and the I-605 in the Seal Beach area. Once completed, the existing carpool lanes on that stretch become express lanes – requiring drivers using them to carry passengers or to pay. In early February 2018, expect to see concrete barriers sprouting along parts of the I-405, along with construction worksites popping up. Later in spring, re-striping will begin so drivers can be shifted toward the freeway’s middle, allowing grading and the removal of trees to the freeway’s sides. In late summer, the heaviest impacts to commuters will begin to break out – demolition and reconstruction of the bridges so the extra lanes can fit beneath them. At least 18 bridges where city streets cross over the freeway along the way must be re-done. The OCTA will supply the popular cell-phone app Waze with information about official detours – hoping to keep drivers from taking impromptu detours through otherwise quiet communities. The OCTA is also developing its own app for the project, along with a web page. Both will provide information about the I-405 construction and street closures.

Rte 405 OC Bridge Destruction In August 2018, it was noted that construction has begun on the I-405 Improvement project, and there was a staggered schedule for bridge closures. The first of 18 bridges set for reconstruction is the McFadden Avenue bridge edging Westminster and Huntington Beach. It will fully close at 10 p.m. Tuesday, Aug. 7, 2018, remaining off-limits for at least a year. Over the following two weeks, the bridge will undergo a two-part demolition, requiring total freeway closures in both directions from 10 p.m. to 7 a.m.. Drivers will be routed off the freeway at the ramp before McFadden Avenue and back on at the next ramp. If driving northbound, that’s Beach Boulevard and then Bolsa Avenue; vice-versa heading southbound. ther bridges with higher traffic volumes will be handled in two stages rather than demolished all at once, a process that will take about 18 months. In those cases, only half of the bridge will be dismantled and traffic will be moved to the remaining side. Eventually, traffic will shift to the completed side and the second half of the bridge will be bulldozed and rebuilt. Next up on the timeline after McFadden Avenue is the Slater Avenue bridge in Fountain Valley, where construction should get underway by the end of 2018. Unlike McFadden, it will remain in use, one side at a time. In addition to McFadden, bridges scheduled to be wholly out of commission during demolition and construction are Bushard Street and Talbert Avenue in 2019, Newland Street and Ward Street in 2020 and Edinger Avenue in 2021. While several bridges may be worked on simultaneously, no adjacent bridges will be closed at the same time. Of the project’s $1.9 billion total price tag, about $1.1 billion will come from Measure M, the county’s half-cent sales tax for transportation improvements. The federal government will cover $45.6 million, and the state $89.7 million. A low-interest loan for $629 million will be paid off by revenue from pay-to-use lanes. Ultimately, the end product will feature two new lanes in each direction – increasing capacity from five to seven lanes. The existing carpool lane on each side will become one of two “express lanes” – still free for vehicles carrying three or more people. Solo drivers will pay a fee for the lanes, as will cars with two people during rush hour. Express lane users will need a transponder that will automatically deduct fees. The price will range from $10 at rush hour to 50 cents at nighttime.

In January 2019, OCTA provided an update on the project. It noted that major construction began in March 2018, when crews began demolishing the McFadden Avenue, Slater Avenue, Bolsa Chica Road and Magnolia Street bridges. 2019 was project to be a busy year for bridge construction, with work planned on the Fairview Road and Bolsa Avenue bridges followed by additional bridge construction later in the year. The McFadden Avenue and Slater Avenue bridges are anticipated to be completed and open to traffic in late 2019.

In August 2019, it was reported that eleven months after it closed to traffic, the rebuilt Slater Avenue bridge in Fountain Valley was reopening. The overpass will be the first of 18 to reopen during the massive expansion of the I-405. Ultimately, the 16-mile stretch of I-405 between Route 73 in Costa Mesa and I-605 in Seal Beach will gain two lanes in each direction. Mills said the entire project is on schedule for completion in early 2023. When one bridge opens, another bridge closes – or, in this case, two. On the same night that Slater reemerges, the Bushard Street and Talbert Avenue overpasses – also in Fountain Valley – will shut down for demolition and reconstruction. OCTA is staggering the closures as a buffer to congestion and inconvenient detours. With two-thirds of the bridges, Fountain Valley and Westminster are the most impacted of the five Orange County cities bordering I-405. In Summer 2018, McFadden Avenue, spanning Westminster and Huntington Beach, became the first bridge to come down. Slater went second. The busiest bridges are undergoing reconstruction in two phases. That way, they can remain open one side at a time throughout – a slower approach that adds about six months to the process. Slater and McFadden have both been renovated in one stage. Yet Slater beat McFadden to the finish line because it was one of the easier bridges, having no freeway on-ramp. Still, it needed to be longer to accommodate the broadened freeway. Due to simple geometry, it wound up about two feet higher, too. Slater is 15 feet wider now, as well, allowing for more generous bike lanes and sidewalks on each side. Another reason Slater moved along quickly was it did not require water and sewer lines, as other bridges do.

[Susan St.]In April 2007, the CTC considered approval of a Negative Environmental Impact Statement and approval of a public road connection for the Susan Street Ramp (~ ORA 11.524). This project would construct a northbound exit ramp about 0.4 miles N of the Route 73 merge ramp onto I-405. The proposed exit ramp would connect to the southern extension Susan Street at the IKEA driveway intersection. The exit ramp is estimated to cost $1.5 million and is fully funded from local sources. Construction would begin in FY 2007-08. The proposed improvement will mitigate congestion by providing direct access from the northbound I-405 distributor road and diverting traffic from the existing Harbor Boulevard and Fairview Road interchanges to this proposed improvement at Susan Street. The proposed improvement is to construct a northbound I-405 off-ramp to Susan Street. Susan Street, a north-south arterial, is located north of I-405 midway between Harbor Boulevard and Fairview Road. The Susan Street off-ramp will begin 0.4 miles west of northbound Route 73 to northbound I-405 merge. The off-ramp extends 0.2 miles as a single lane and widens to three lanes at the ramp terminus. The Susan Street off-ramp will be braided below the Fairview Road on-ramp to northbound I-405. The proposed improvements will increase the capacity and improve operations of the existing Harbor Boulevard and Fairview Road interchanges.

In August 2015, the CTC authorized $82,000,000 for a project in Orange County on I-405 in Fountain Valley, from Ellis Ave/ Euclid Avenue to Magnolia Street (~ ORA 12.433 to ORA 15.224) that would construct auxiliary lanes in each direction as part of the larger I-405 Widening project EA 0H100. This project is necessary to reduce congestion and improve highway operations and mobility.

The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures for this route:

Route 405/Route 22 Connectors (~ ORA 20.459 to ORA 23.496)

Inst 405/Rte 22 InterchangeAt its meeting on July 9, 2009, the CTC approved a CMIA project baseline agreement amendment to split the Route 22/405/605 HOV Connector with ITS Elements project (PPNO 2868C) into two construction projects: (1) Route 22 to I-405 between Seal Beach Boulevard and Valley View Street (PPNO 2868B); (2) I-405 to Route 605 between Katella Avenue and Seal Beach Boulevard (PPNO 2868C). In October 2009, the funding was rearranged to give some priority to the first of these two. In February 2010, the CTC approved amending the CMIA Program project baseline agreement for the Route 22/405/605 HOV Connector project (PPNO 2868C) to transfer $3,360,000 from CMIA reserve to Construction and reduce Congestion Mitigation and Air Quality Program (CMAQ) funding by $24,100,000.

In September 2012, construction crews will shut down the eastbound Route 22 connector to the northbound I-405 for one year. The transition road, which carries about 3,000 vehicles a day must be rebuilt to make way for the new carpool lane connector between I-405 and I-605. During construction, the eastbound Route 22 transition to the northbound I-605 will remain open. From eastbound Route 22, the Orange County Transportation Authority advises motorists to exit and turn right at Studebaker Road and continue north to access the northbound I-405 on-ramp. All of the construction is part of a project that will connect carpool lanes on I-405, I-605 and Route 22. It's scheduled for completion in 2014.In December 2010, it was reported that construction was beginning, and commuters will be hit hard. The $277-million freeway project requires a series of road closures, including one of the main portals to a veterans' hospital and a major state university. The work will be done in two segments, and lane and street closures are to be sequenced to minimize some of the traffic impacts. When completed in 2014, the so-called West County Connector project built by the Orange County Transportation Authority will create a seamless link between carpool lanes and ease rush-hour bottlenecks on the I-405, Route 22 and I-605 freeways. The project calls for an additional carpool lane in each direction of the I-405 between Route 22 and I-605. Large overpasses will be built to connect the carpool lanes on the I-405 to those on the other freeways. Bridges and connectors throughout the project area are to be rebuilt, including those at 7th Street, Valley View Street and Seal Beach Boulevard. Onramps and offramps related to those structures also will be redone. In addition to 7th Street, two other heavily traveled bridges will be affected by the project: Seal Beach Boulevard over the I-405 and Valley View Street over Route 22. The number of traffic lanes will be reduced on the bridges for 11 months and 20 months, respectively.

Orange County to LAX

I-405 Expansion in Orange County - Long Beach Reaction (LA 0.000 to LA 2.265)

The LA Times reported in 2009 on a dichotomy between Los Angeles and Orange County regarding I-405 widening. Although Orange County has plans to add up to two lanes on each side of the roughly 14-mile stretch of I-405 between Route 73 and I-605. Bridges would also be rebuilt, some homes would be taken under eminent domain and the carpool buffer would shrink. However, Los Angeles county has no plans for widening. One reason is that the L.A. County side has less space for expansion than Orange County does. Los Angeles county has focused more energy and funds towards rail lines. This may create a problem similar to that seen on I-5 at the county line.
(Source: Los Angeles Times, 11/17/2009)

In July 2013, it was reported that Long Beach has protested the expansion plans in the original study. The revised study presents three alternatives, in addition to the required no build alternative:

According to the supplemental study, between two to five intersections (not including ramps) in Long Beach would be impacted if one of the improvements is built. That number rises to four to nine intersections by 2040. The intersections immediately impacted by all three alternatives are at Los Coyotes Diagonal (~ LA 2.265) and Bellflower Boulevard and Willow Street and Bellflower Boulevard. If one of the larger alternatives is chosen, impacts are expected at Willow Street and Woodruff Avenue and Willow Street and Los Coyotes Diagonal. Percentages of intersection improvement costs paid for by Caltrans and OCTA in the draft report range from 30% to 4.45%, with each intersection costing between $240,000 to $810,000.

In August 2013, the CTC received a draft EIR for comment. The project in Los Angeles and Orange Counties proposes to construct roadway improvements on Interstate 405 (I-405) within the project limits, including 15 local street interchanges and three freeway-to-freeway interchanges (12-Ora-405, PM 9.3/24.2, 07-LA-405, PM 0.0/1.2, 12-Ora-22, PM R0.7/R3.8, 12-Ora-22, PM R0.5/R0.7, 12-Ora-73, PM R27.2/R27.8, 12-Ora-605, PM 3.5/R1.6 07-LA-605, PM R0.0/R1.2). The project is not fully funded. Depending on the alternative selected, the total estimated project cost ranges between $1.3 billion and $1.7 billion. The project will seek funding through the State Transportation Improvement Program, federal and local fund sources, and possibly toll revenue. Depending on the availability of funding, construction is estimated to begin in Fiscal Year 2015-16. Alternatives considered for the proposed project include:

  1. No Build Alternative.
  2. Alternative 1 - This alternative would add one general purpose lane in each direction of I-405 from Euclid Street to the I-605 interchange.
  3. Alternative 2 - This alternative would add one general purpose lane in each direction of I-405 from Euclid Street to the I-605 interchange and add a second general purpose lane in the northbound direction from Brookhurst Street to the Route 22/ 7th Street interchange.
  4. Alternative 3 - This alternative would add one general purpose lane in each direction of I-405 from Euclid Street to the I-605 interchange and add a tolled Express Lane in each direction from Route 73 to Route 22 East.

According to the August 2013 revised study, the following measures would be incorporated to minimize impacts of the project:

  1. A payment shall be made by the Orange County Transportation Authority (OCTA) to the City of Long Beach to cover the project’s fair share cost of the improvements at intersections owned by the City of Long Beach.
  2. A payment shall be made by OCTA to the California Department of Transportation based on a Traffic Mitigation Agreement Fair Share Deferment.

In July 2015, it was reported that Long Beach is suing Caltrans and the Orange County Transportation Authority over the $1.7 billion project to expand I-405. The City Council authorized the city attorney in closed session Tuesday to file the lawsuit challenging the environmental documents filed with the plan, which widens I-405 by four lanes through Orange County to just past the Long Beach border. The city is seeking additional measures to reduce the impact of increased traffic on local streets. The environmental impact report for the I-405 expansion lists five intersection that will see improvements in Long Beach related to the widening plans, but assigns about 7-25 percent of the cost for the upgrades to OCTA. The rest is expected to be picked up by the city.
(Source: LB Press Telegraph 7/14/2015)

In April 2017, it was reported that completion of the upgrade of the Wilmington Interchange (~ LA 9.553) was delayed. Expansion of the often-clogged interchange was supposed to finish early in 2016, but now completion isn’t expected until 2018. Not only is the project two years behind schedule, it will cost $8 million more than expected because of delays and unanticipated underground utilities that got in the way. This widening project was conceived in 2005 to open up the intersection and freeway ramps so vehicles could more quickly move through. Work is being done in five stages, with the third stage now nearly complete. A newly built northbound I-405 on-ramp is nearly ready to open, and much of the work on the dam and bridge over the Dominguez Channel is done. Next, the bridge will be repaved. Wilmington Avenue also is being widened between East 223rd Street and East 220th Street, and new pavement and other upgrades are being added to the intersection and southbound ramp. The project’s two-year delay is largely because Southern California Edison was extremely slow to respond to work requests needed before construction stages could begin. The company thought Edison would take months to do work that it took years to do, said officials. Also, numerous underground oil pipelines and utility lines, ducts and vaults were encountered that weren’t anticipated in design plans. The Metropolitan Transportation Authority and Federal Highway Administration financed much of the total $27 million cost. But bond funds were also used from Carson’s Successor Agency, the city’s former redevelopment arm.

Avalon Interchange Improvements (~ LA 11.24)

The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures for this route:

In October 2011, the CTC approved for future consideration of funding a project in Los Angeles County that will improve the Avalon Boulevard/I-405 interchange by constructing a new southbound on-ramp, widening the northbound off-ramp and on-ramp, and widening northbound Avalon Boulevard. The project is fully funded with Local and Federal funds. This project will be requesting a New Public Road Connection from the California Transportation Commission at the October 26-27, 2011 Meeting. The total estimated cost is $19,300,000. Construction is estimated to begin in Fiscal Year 2010-11. A copy of the ND has been provided to Commission staff. Due to potential impacts to visual resources, hydrology and water quality, community impacts, cultural resources, and the local economy, an Initial Study was completed for the project. Based upon environmental studies and proposed environmental commitments, including minimization and avoidance measures, incorporation of BMPs, limited hours of construction, the project will not have a significant effect on the environment. As a result, an ND was completed for this project.

The proposed new route connnection will be at Lenardo Drive. The specific proposal is to modify the Avalon Boulevard/I-405 interchange in the city of Carson to provide access to the approved development of the Carson Marketplace Project in the southwest quadrant of this interchange. The modifications to this interchange include the southerly extension of Lenardo Drive over the Torrance Lateral Channel to connect to Avalon Boulevard and the realignment of the southbound I-405 on and off ramps to begin and end at Lenardo Drive. This break in access control requires the approval of a new connection by the California Transportation Commission. The proposed improvements support the additional access needs of the Carson Marketplace Project and also address growing traffic volumes in the vicinity. The Avalon Boulevard interchange is located in the city of Carson, in Los Angeles County, between the Main Street and the Carson Street interchanges along I-405. I-405 has 12 lanes north of Avalon Boulevard and 10 lanes south of Avalon Boulevard. Traffic in the southbound direction is served by a loop on-ramp and a diagonal off-ramp in the southwest quadrant of the interchange. In the northbound direction the interchange is a half diamond. Avalon Boulevard is a major thoroughfare through the City of Carson with four to six lanes serving primarily residential, commercial, and light industrial traffic demands. The proposed interchange modification would extend the existing Lenardo Drive south from the proposed Carson Marketplace over the Torrance Lateral Channel to Avalon Boulevard. The existing southbound I-405 on- and off-ramps, located between the Torrance Lateral Channel and Avalon Boulevard, will be realigned and widened. A new two-lane southbound on-ramp will be constructed east of Avalon Boulevard and across from Lenardo Drive. The existing northbound off-ramp will be widened from one to three lanes at the terminus to increase storage capacity and to accommodate left turns. The northbound on-ramp will also be widened to increase capacity and accommodate two left-turn lanes from northbound Avalon Boulevard. The existing Avalon Boulevard structure will be widened and repaved.

In March 2016, the CTC approved additional funding for a project on Route 405 in Los Angeles County from LA 12.6 to LA 21.2 (essentially, from I-110 to I-105) that will install concrete barrier and metal beam guardrail along the project limits.

Route 110 / Route 405 Interchnage Improvement (~ LA 12.875 to LA 13.013)

In March 2016, the Los Angeles MTA presented its full proposal for what transit lines could be built -- and when -- if Los Angeles County voters approve a half-cent sales tax increase in November 2016. This proposal included funding for the I-110 Express Lane Ext South to I-405/I-110 Interchange. The new project would extend the existing I-110 Express Lanes southward to the I-405, for a total of 1 mile. This will create a total of 5 Mixed-Flow lanes and 1 Express Lane for that mile. Additionally, the proposal included funding for direct connector ramps between the I-110 and I-405 express lanes. (~ LA 12.875)

Rte 405/110 InterchangeIn May 2018, it was reported that ground was broken for the 405/110 interchange project (~ LA 13.013). The $35-million I-110/I-405 interchange improvement project will widen the northbound San Diego Freeway connector to the southbound Harbor Freeway. A new auxiliary lane will also be constructed from the I-110/I-405 interchange to Del Amo Boulevard. Construction is anticipated to be completed in 2021. Metro provided seed funding for the project’s initial environmental work through its Measure R transportation sales tax that was approved by voters in 2008. The SB1 "gas tax" allowed the improvement project to be fast-tracked. Another $1.2 million of environmental work enabled the SBCCOG and Metro to have the project shovel-ready when the funding became available last fall.

The project will add segments of an Auxiliary Lane in each direction to address existing bottleneck and to improve the weaving movements at on/off ramps, from I-110 to Florence Ave. for a total of 10.4 miles, while maintaining the current existing facility consisting of 4 Mixed-Flow lanes and 1 HOV lanes in each direction.

Crenshaw Interchange (~ LA 15.451)

In June 2015, it was reported that Caltrans was seeking public reaction to an environmental analysis prepared for the pending reconstruction of the chronically congested Crenshaw Boulevard and 182nd Street interchange with I-405 that’s scheduled to start in July 2018. The complex, four-year-long project is expected to cost $60.5 million to $85.2 million for its design and construction depending on which of three alternatives is selected. The entire interchange is persistently overloaded, a situation that worsens considerably during rush hour. Short on- and off-ramps create potentially dangerous lines of vehicles on surface streets and on the freeway itself, hampering the efficiency of I-405. Improvements to be made include: (•) Adding an additional lane to the existing freeway on‐ and off- ramps and constructing a new two-lane on‐ramp to the SB I-405 from Crenshaw Boulevard; (•) Widening Crenshaw Boulevard south of the interchange to make room for a new, exclusive right-turn lane onto the proposed new southbound on-ramp; (•) Widening westbound 182nd Street between the NB I-405 on- and off-ramps and Crenshaw Boulevard; and (•) Building or reconstructing more than more than 12,000 feet of sound walls.
(Source: Daily Breeze, 6/24/2015)

In October 2016, the CTC approved for future consideration of funding a project in Los Angeles County that will widen I-405, including the existing on- and off-ramps on Crenshaw Boulevard, and construct a new southbound on-ramp from Crenshaw Boulevard. The project is not fully funded. The project is fully funded for the environmental phase only with local funds. The total estimated cost is $87,100,000 for capital and support. Depending on the availability of funding, construction is estimated to begin in Fiscal Year 2020.

The 2018 STIP, approved at the CTC March 2018 meeting, appears to allocate $12,000K for PPNO 4410, Crenshaw Blvd Interchange Improvements. This would be construction support in FY22-23, meaning the project is delayed.

The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures for this route:

LAX to West Los Angeles

In August 2015, the CTC authorized $14,130,000 for a project in Los Angeles County, on I-405 in and near the cities of Inglewood, Culver City, and Los Angeles, from 0.2 mile north of El Segundo Boulevard to Venice Boulevard (Route 187) (~ LA 20.413 to LA 27.983) that will rehabilitate 56 lane miles of pavement by replacing cracked slabs, grinding concrete pavement, overlaying ramp and shoulder asphalt pavement, installing new guardrail, and paving miscellaneous areas. This project is necessary to extend pavement service life and improve ride quality.

[Arbor-Vitae Map]There are continual discussions about adding an interchange at Arbor-Vitae (~ LA 22.759). Based on an article in the Daily Breeze, the plan is based on a much earlier plan to construct a new interchange along I-405 at Arbor Vitae Street. The project was original initiated by Los Angeles World Airports (Los Angeles Department of Airports at the time) in 1976 to provide an alternate East-West access route between I-405 and the Los Angeles International Airport. This project was part of a larger project proposed in 1980 and scheduled to be constructed in 1984. However, the Arbor Vitae Interchange had been postponed multiple times due to funding considerations. The current version of the project entailing the south half of the interchange and widening of the Arbor Vitae Bridge was going to be constructed in 2002. However, the delivery of this project was postponed for three reasons: First, opposition from local residents, who live adjacent to the proposed project, and the Inglewood Unified School District Board was prevalent during the public comment periods; second, the Southern California Association of Governments (SCAG) did not support the construction of the full interchange, and led to the current south half version of the interchange. Third, the Federal Highway Administration (FHWA) would only approve an environmental document that includes the full interchange. It lacks support from local elected officials. At this time, this project is programmed through the Project Approval/Environmental Document [PA/ED] phase (the current phase). There is only partial funding currently programmed for the construction of this proposed project; an additional $37 million is needed to construct this project. If approved, the project will be funded from the State Transportation Improvement Program (STIP) and the Regional Transportation Improvement Program (RTIP). The proposal called for a new south-half interchange, including a southbound on-ramp to I-405 from a widened Arbor Vitae overpass, as well as a northbound off-ramp from the freeway to the street. The project’s purpose is to reduce congestion at the Century Boulevard and Manchester Boulevard interchanges by creating along Arbor Vitae Street, from the I-405, a new direct vehicle access to and from the Hollywood Park Casino, the University of West Los Angeles, the Forum, and Centinela Hospital. The project would result in the agency taking nine homes and two businesses - down from roughly 50 homes under an earlier plan, which also encroached on an Inglewood school site, according to planning documents. A later meeting indicated a fair amount of opposition to the plan. In September 2010, it was reported that Caltrans had cancelled plans for this interchange. Specifically, Caltrans chose the "no-build" alternative - which was based on several factors, including the project's anticipated effects on traffic conditions along local streets, community opposition as well as funding. The agency needed roughly another $30 million to fund the estimated $82 million project. Additionally, a Caltrans letter stated that the Federal Highway Administration failed to grant the exception needed to build the proposed half-interchange.

In October 2014, the CTC authorized additional funding for the project in Culver City, from La Tijera Boulevard on-ramp to Jefferson Boulevard off-ramp (~ LA 24.282 to LA 25.752), that will construct an auxiliary lane to improve traffic flow and reduce congestion. The project widens and seismically retrofits the Centinela Avenue Undercrossing (No. 53-1253) and the Sepulveda Boulevard Undercrossing (No. 53-1254 ). The Howard Hughes Parkway on-ramp and the Sepulveda Boulevard off-ramp will also be realigned and widened as part of the project. The project also constructs retaining walls to accommodate the widened roadway. The project relieves congestion by improving traffic operations.

In 2008-2009, Caltrans widened I-405 from ten to twelve lanes from Route 90 to I-10 (~ LA 25.72 to LA 29.429). This project added one HOV lane northbound. It resulted in signficant changes in the Culver Blvd offramp. The the previous NB exit that deposited Culver traffic at Braddock and Sawtelle was removed; it was replaced by a direct offramp at Culver. A similar change was made for southbound traffic. The lanes were opened in November 2009. The $167 million widening project took five years to complete, and added carpool lanes and exit lanes on the freeway. The five main traffic lanes in each direction were widened from 10 feet wide to 12 feet, and the often-uneven asphalt surface next to the center divider was replaced with concrete.

In December 2013, the CTC authorized relinquishment of right of way in the city of Culver City adjacent to Route 405 between Sawtelle Boulevard and Barman Avenue, consisting of a reconstructed city street (~ LA 27.046).

In 1989, the CTC relinquished roadway that predated Route 405 (i.e., former Route 7): Sepulveda Blvd between I-405 and Slauson. (~ LA 26.029)

The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures for this route: (~ LA 29.429 to LA 39.183)

I-10 to Waterford HOV Lanes (~ LA 29.677 to LA 32.126)

In 2008, a project was completed that widened the freeway and added southbound HOV lanes between Waterford St and 0.5 km S of I-10. This section of the freeway was origianlly constructed on a fill segment between 1958 and 1963. It was an eight-lane facility consisting of four 12 ft lanes, with 8-10 ft shoulders and a 22 ft median. Later restriping reduced this to a non-standard 11 ft lanes, with the median being used to add two mixed flow lanes and a 4 ft non-standard half-median. The project widened the existing freeway to add an 11.8 ft HOV lane, and a 2 ft buffer next to the median. The five existing mixed flow lanes were restriped even narrower as four 10.8 ft lanes and one 11.8 ft lane. A 9.8 ft outside shoulder, and a 3.3 ft half median was also provided. To eliminate weaving conditions, two auxiliary lanes were added. One was added upstream of the SB off-ramp to WB Wilshire Blvd, and included widening of the off-ramp. The second was added between the SB I-405 on-ramp from Santa Monica Blvd and the SB I-405 off-ramp at Olympic Blvd. The current auxiliary lane between Santa Monica Blvd and Wilshire Blvd was maintained. Additionally, the Waterford Street on-ramp SB was closed. The total cost for this project is $74.4 million, with an estimated completion of August 2006 (although this date was not met). This is TCRP Project 52. It was completed around 2008.

In June 2017, the CTC was informed that, for TCRP Project 52 - Route 405; HOV and Auxiliary Lanes – Waterford Avenue to Route 10 (PPNO T0520), the authorized amount was $25,000,000, of which $9,648,000 was previously programmed and allocated to the project. Due to the suspension of TCRP funding in 2003, this project was delivered with other State funds, leaving $15,352,000 in unallocated TCRP funds on the project. In June 2016, the Commission approved a TCRP policy for projects programmed in Tier 2 and in January 2017, funding for Tier 2 programmed projects became available. TCRP 52 is currently on the Tier 2 list for $15,352,000. The Department and Metro propose to amend Project 52 to de-program $15,352,000 in TCRP savings and update the project funding plan and transfer the funds to fund TCRP Project 38.2, Los Angeles -San Fernando Valley Transit Extension and TCRP 50, Route 71.

LA Metro Improvements - HOT/Tunnel, West LA to San Fernando Valley

In March 2016, the Los Angeles MTA presented its full proposal for what transit lines could be built -- and when -- if Los Angeles County voters approve a half-cent sales tax increase in November 2016. This proposal included funding for some form of Sepulveda Pass Transit Corridor. The specific approach was not specified: it could be a new high capacity transit mode connecting the Orange Line Van Nuys station underneath the Sepulveda Pass, with a station at UCLA, terminating at Wilshire/Westwood Purple Line station. Approximately 8.8 miles. The project might also include restriping the HOV lanes within the existing Right of Way to add 2 ExpressLanes in each direction (while maintaining the current 4 Mixed-Flow Lanes), from US-101 to I-10 for a total of 10 miles. There have also been rumors of a private vehicle toll tunnel under the Sepulveda Pass.

Sepulveda Pass Improvements / Initial HOV and Widening, Waterford to US 101 (~ LA 32.126 to LA 39.2)

Inst 405 HOV mapNorthbound, there are plans to add an HOV lane between I-10 and US 101. In September 2000, the California Transportation Commission considered a proposal (Traffic Congestion Relief Program Project 39) to add the northbound HOV lane over Sepulveda Pass, from I-10 to US 101. Phase 1 of the proposal was estimated to cost $15 million, with a total cost of $336 million. This is TCRP Project #39, and has an estimated completion date sometime in the year 2016, with construction starting in 2006. The desired goal is 6 mix-flow and 2 HOV lanes in each direction, but initially there will be one HOV lane and five mixed flow lanes. It was requested by the LA County Metropolitan Transportation Authority.

The project will provide a continuous HOV system on Route I-405 by closing a gap in the current system. Estimates to add the HOV lane range from $500 million to $750 million. Work on the environmental phase of the project began in Fiscal Year 2000-01. Severe fiscal crises in the following years resulted in the temporary suspension of various transportation funding sources, including TCRP. Due to the prospective lack of funds to proceed beyond the Environmental phase, the Department delayed work on this project. However, with the appropriation of Proposition 42 funds, and $130,000,000 in new federal earmark funds (SAFETEA-LU), the environmental phase began. During this phase, the Department identifies individual segments for construction. The Federal earmark funds of $130,000,000, along with the remaining un-programmed $75 million of TCRP funds will be used to deliver one or more these segments. The schedule and funding plan are for environmental only. This phase is scheduled to complete in July 2008.

A 2006 bond measure provided additional funding for completion of the northbound HOV route system. This has gone through a lot of funding hurdles, especially in relation to funds from the 2006 Corridor Mobility Improvement Account. Originally, the project was not recommended because it was believed construction would start too late. The decision was later rescinded, and the project was approved for $730 million in funding. The total cost of the project is $950 million. As of March 2007, Caltrans had five proposals for this construction:

  1. Alternative 1: No Build
  2. Alternative 2: The widening of the existing facility to add a northbound HOV lane.
  3. Alternative 3: The widening of the existing facility to add a northbound HOV lane and restore southbound freeway lane and shoulder widths to current design standards.
  4. Alternative 4: The widening of the existing facility to provide for four HOV lanes (two each, both northbound and southbound) on an elevated viaduct, within the freeway median
  5. Alternative 5: Transit Enhancement Alternative. This would involve design features that would facilitate increased transit use in the corridor.

Many of these alternatives are engendering quite a bit of controversy, especially Alternative 3, which would involve the taking of a significant amount of property, including churches, hotels, and multi-family residences in an affulent area. Specifically, Caltrans has noted that the most extensive plan (Alternative 3, about $911 million) takes up to seven Sherman Oaks homes and thirty Brentwood properties. This alternative is present because the narrower SB lanes have a higher accident rate. Alternative 2 (about $649 million) would still take the seven Sherman Oaks homes, and portions of about forty, and leave the southbound side of I-405 unchanged.
(Ref: Los Angeles Times)

In July 2007, Caltrans released a modification to the plan that appeared more acceptable. This modification would add a mixed flow lane SB between Skirball Center and Waterford St., close the SB I-405 on-ramp from EB Sunset Blvd, reconfiguring the intersection to direct traffic to use the SB entrance just N of Sunset Blvd., and realigning portions of Sepulveda Blvd. There would also be realingment of the Skirball Center ramps.There would also be relocation of the Valley Vista ramps SB. The option would also move I-405 east, permitting a simple narrowing of Church Lane, instead of relocation (and thus saving a lot of properties). In August 2007, the CTC approved programming $27,000,000 in new TCRP funds for Plans, Specifications and Estimates (PS&E) for this project, and changed the Phase 2 completion date to FY10/11. Without widening, traffic on I-405, described as one of the worst in the nation, is forecast to increase 46% from 2005 to 2031.

In February 2008, it was announced that Caltrans had decided on a plan that will result in only a few homes being taken, in the vicinity of Valley Vista Blvd. This appears to be the less-severe option (the July 2007 modification), which itself has had a few modifications.
[Source: LA Daily News, 2/25/2008]

In June 2008, the CTC approved the selected alternative for the Route 405 construction. The alternative selected was Alternative 2: which widens the facility solely to add a NB HOV lane. This alternative will still take seven Sherman Oaks homes, and portions of about forty, but it will leave the southbound side of I-405 unchanged. The NB roadway will meet current design standards for lane, median, and shoulder widths except at the I-10/I-405 interchange and between Moraga Dr. and Sunset Blvd interchanges. Standard lanes consist of an 11' half median, a 12' HOV lane, a 1' HOV buffer, 5 12' mixed-flow lanes, and a 10' outside shoulder. The selected alternative would also widen the SB I-405 to meet current design standards for lane, median, and shoulder widths at certain sections. SB standardization would be within the following segments: Olympic Blvd and Waterford St, and between Bel Air Crest to the north end of the project. Local interchanges within the project limits would be reconstructed and improved notably at Wilshire Blvd, Sunset Blvd, and Skirball Center Drive. There is the goal that wall designs be compatible with the surrounding community. There are also plans to improve wildlife crossings.

In early 2009, it looked like the project might be out of luck, due to a $730 million shortfall. The project was supposed to begin in mid-May, largely paid for with bond revenue awarded in 2007. However, that money was temporarily rescinded in December 2008 as the Legislature struggled to close a $42 billion deficit. As of April 2009, the freeway project has about $378 million - including the $200 million in stimulus money - enough to continue the project for 15 months. About $13 million in local money and $48 million from a state traffic relief program are secured for the lane. The federal government has kicked in $117 million, separate from the stimulus money, contingent on construction starting in 2009. The LA MTA eventually decided to start the project, hoping that they could come up with the money later. Although the MTA has just a fraction of the project's $1 billion price tag, construction of the 10-mile northbound car-pool lane should begin in summer 2009. The project, approved by the Los Angeles County Metropolitan Transportation Authority board, is expected to create some 18,000 construction jobs and be completed in 2013. The MTA still needs to raise $614 million — money originally approved by voters in a bond measure but withheld by the state as it grappled with its massive budget deficit — to complete the project. In case the remaining money never materializes, the Metro board agreed to set aside $30 million to cover the costs of suspending or ending construction contracts. In early May 2009, MTA will award a $712 million construction contract to Kiewit Pacific Co. for the widening project. With $372 million in hand, there is enough money to keep the project going for 15 months. That will pay to relocate water, gas and phone lines and work on some freeway ramp widening.
[Source: LA Daily News, April 2009]

In April 2009, the CTC approved funding this project (as a loan against future bonds) from 2009 Stimulus funds.

Construction on this project started in January 2010. The project includes a 10-mile HOV lane on the northbound I-405 between I-10 and US-101; removal and replacement of the Skirball Center, Sunset Blvd. and Mulholland Dr. bridges; realingment of 27 on and off ramps; widening of 13 existing underpasses and structures; and construction of approximately 18 miles of retaining wall and sound wall. The construction work is quite complicated. Every task - from setting up K-rails and street cones to excavating foothills and readjusting freeway lanes - must be managed between 10p and 6a. Crews must minimize the noise and ensure that their lights don't shine into windows or along wildlife corridors. They must also avoid the inordinate number of oil and gas lines under the route and utility poles alongside the route.

In May 2010, work began on the demolition of the Sunset Blvd bridge. Mostly this has been preparation work: relocation of utilities, restriping of lanes, etc. It was estimated the bridge demolition would begin in mid-May, but as of late June no demolition had started. The plan is to keep the bridge open as it is rebuilt. The southern half of the bridge was completed in July 2010.

Inst 405 skirball center bridgeIn October 2010, demolition work began on the Skirball Center bridge. Demolition went fast, and was the northern half was completed in October 2010. There are two options being considered regarding the Skirball Center ramps. The first would keep the ramps where they are. The second would relocate the SB ramps south of the current Skirball bridge. The preferred option, based on traffic analysis, is the relocation of the ramps. This has the additional benefits of adding a lane to Skirball Center Drive E of I-405, adding a sidewalk to the W side of Skirball Center Drive from the new Mulholland Bridge to the Skirball bridge, adding a sidewalk to the N side of the bridge, and having more space for bicyclists on the bridge. There will also be new signage directing visitors to the Skirball Cultural Center, a dedicated northbound right-turn lane between new SB ramps and Skirball Bridge, bicycle lanes on Sepulveda Bl between Skirball Bridge and new southbound ramps, and southbound hook ramps that provide greater ramp storage capacity. There will also be a dedicated right-turn lane from northbound Sepulveda Bl onto new southbound I-405 on-ramp, and a dedicated double left-turn lane from southbound Sepulveda Bl onto southbound I-405.

In September 2010, it was reported that Caltrans and Metro have finally decided to alter the way the impressively high, 1959-era Mulholland Drive bridge is replaced during the I-405 widening project: they will build an all-new bridge before they tear down the old bridge. This actually saves $4 million to $10 million over juggling the two projects. Coming from the west, drivers would enter the new bridge in the same place they do now, then angle slightly south across the freeway before ending up on Skirball Center Drive. Only after the new span was completed would the old one come down, thus reducing traffic-related inconvenience during construction. However, those plans were changed in early 2011 back to the original approach due to complaints from those in the area. There was concern from residents and environmentalists about increased traffic congestion and threats to wildlife; there were also demands that the new bridge be designed by a world-class architect (which was the deal-breaker, cost-wise, for Metro).

In October 2010, an article was published that highlights the problems in this construction. Consider utility relocation. Shell, Chevron, Exxon and Mobil each have oil pipelines through the pass. SCS Energy has a natural gas pipeline to UCLA. There are fiber optics lines. Southern California Gas Company and Southern California Edison bring gas and electricity to their customers through the pass. Verizon and ATT connect residences and business via the Sepulveda Pass, and the Metropolitan Water District has a 96-inch-diameter water line under Sepulveda Boulevard. Some of those utilities run along and through the three bridges to be replaced—Sunset, Skirball and Mulholland—complicating their demolition and reconstruction.

Inst 405 Wilshire RampsIn December 2010, it was reported that the project will involve reconfiguration of the southbound Wilshire Blvd interchange, adding flyover ramps to eliminate the intercrossing of exiting and entering traffic. Currently, vehicles trying to get off the freeway onto Wilshire must jockey with other vehicles entering the freeway. Under the new configuration, the on ramps and off ramps are completely separate.

In May 2012, it was reported that the rampture would begin in June 2012. This is the first 90 day closure of the Wilshire ramps. This closure includes the Westbound Wilshire on-ramp to Northbound I-405, and the Northbound I-405 off-ramp to Westbound Wilshire. The six other Wilshire ramps will be closed consecutively, some two at a time, between 14 and 90 days. The image below provides additional details:

RamptureIn July 2011 (the weekend of July 15-16), "Carmageddon" has been predicted as Caltrans closes the entire I-405 freeway roughly between Sunset Blvd and US 101 in order to demolish half of the Mulholland Bridge. Details here. The following is a description of how the southbound portion of the bridge is being demolished:

The demolition timeline will begin Friday evening, July 15, 2011 when work crews begin closing freeway on- and off-ramps between the I-10 and US 101 as early as 7 p.m. to prevent additional vehicles from entering into the closure area. Crews will then begin closing freeway lanes one by one on both sides of the freeway at 10 p.m. in order to achieve a full freeway closure by midnight. The Mulholland Bridge also will be closed. The area surrounding the Mulholland Bridge will be lit up like the Astrodome utilizing two very large light plants and about 12 regular light plants. Staged in nearby project construction yards and other areas, 15 pieces of heavy construction equipment (with another five on standby) and an army of 100 demolition workers and support staff will be poised to begin their precision operation. Starting at 12 midnight, trucks will begin to haul dirt onto the 405 freeway underneath the Mulholland Bridge to form a cushion four feet high on the freeway roadbed. The dirt will catch falling debris and prevent concrete pieces from damaging the freeway lanes. At approximately 2 a.m. Saturday morning, workers will use a large diamond-bladed saw to cut the bridge top deck and soffit to safely demolish the southern half while keeping the northern half structurally sound. Workers also will cut slots in the southern side of the bridge to quicken the demolition process. During demolition work, workers will perform vibration monitoring and other tests to ensure the structural integrity of the northern side of the bridge is retained at all times. At approximately 5 a.m. Saturday morning, as many as four “hoe rams,” or rolling jack hammers of various sizes will begin to chip away at the south side of the bridge. Approximately 4,000 tons of concrete will be removed in the first phase of demolition work. Two Hoe rams will be stationed on the bridge deck starting in the center working toward each end. Once they have reached the ends of the bridge, two hoe rams will begin to work on the ground also starting in the center and working toward both ends. These giant and powerful demolition machines will deliver between 1,200 and 7,500 foot-pounds of power to break away concrete from the bridge. This compares to 90 foot-pounds delivered by a common hand-held jack hammer. Operators in these machines will be able to deliver between 300 and 600 blows per minute on the concrete decking to break pieces into sizes no bigger than a basketball or microwave oven which can then be easily hauled away from the demolition site. Later, the concrete will be pulverized and recycled. The bridge’s railing will also be taken down by hoe-ram. Front-end loaders will also be used during the demolition to load demolition debris into trucks. While the hoe rams steadily chip away at the concrete, other workers using long-handled oxygen/acetylene torches will cut the steel rebar from the bridge deck amid a crackle of sparks. Workers will be tied to a secure anchor and will be wearing fall protection equipment as they work. Workers will continue to cut the rebar into smaller pieces on the ground so that it can also be recycled. This demolition work is expected to last throughout Sunday, July 17 as crews also demolish the bride’s south columns, leaving the other two columns in-tact to support the north side of the bridge. Once the demolition operation is complete, an army of laborers will thoroughly clean the edge of the bridge to assure that no particles are left to fall on the traffic below. Finally, the remaining portion of the bridge will be inspected by structural engineers from Kiewit and Caltrans. This demo work is expected to last until 2 a.m. Monday morning, July 18, when crews will wrap up demolition and begin their final cleanup to prepare the freeway for reopening by 5 a.m. Between 10 and 20 large trucks and several front end loaders will be used for the cleanup. The freeway surface under the bridge will be cleaned by a parade of street sweepers, inspected, and finally restriped with fresh paint. Ramps and freeway connectors will reopen by 6 a.m.

Debris from the demolished bridges has been used for the construction of the Metro Orange Line in Chatsworth.

The second "carmageddon" occured the weekend of September 29, 2012.

Larry Scholnick provided a good summary of all the work involved in this simple HOV lane addition: The basic goal of the project is to install a northbound HOV (carpool) lane from I-10 (where the NB HOV lane becomes a regular, mixed-flow lane) to US-101 (where the NB HOV lane resumes). No additional regular, mixed-flow lanes will be built; there will continue to be 5/6 NB through lanes (5 South of Skirball Center and 6 North of Skirball Center) and 5/4/5 SB through lanes (5 north of Skirball Center, 4 between Skirball Center and Waterford, and 5 south of Waterford). At first glance it seems like the freeway should only be widened by 12 feet. However, there are currently no center breakdown lanes on either side of the freeway, so this project will add those lanes. At second glance it seems like the freeway will be widened by (12+10+10) 32 feet. However, the existing lanes are about a foot narrower than the current 12-foot standard, so all 10+ existing lanes (5+ NB plus 4+ SB plus one SB-HOV) will we widened by a foot, so the total widening will be over 40 feet. For the section between Olympic and Santa Monica Blvds this is comparatively easy because there is extra right-of-way that was originally intended for the connectors to the (never-built) Beverly Hills (CA-2) Freeway. The interchange with Wilshire Blvd is a full cloverleaf, made up of four onramps and four offramps. Each ramp has a tight turning radius, typical of 1960's construction. In order to eliminate weaving, and to modernize the interchange, all 8 ramps will be torn down and replaced. The ramps will be replaced in pairs; WB-NB & NB-EB will be replaced first. When complete there will be flyover ramps that will eliminate weaving; EB-NB will fly over NB-WB, and SB-EB will fly over WB-SB. The new ramps that include bridges over Sepulveda will leave room for a wider Sepulveda to go under. Every bridge where the freeway crosses OVER a surface street (Exposition, Pico, Olympic, Santa Monica, Ohio, Wilshire, Constitution, Montana, Church, Getty Center, Sepulveda near Getty Center, Bel Air Crest, Sepulveda near Valley Vista and perhaps Ventura) will be widened. All onramps and offramps that are not being replaced will be realigned to the widened freeway. Each bridge where the freeway crosses UNDER a surface street (Sunset, Skirball Center, and Mulholland) will be replaced with a bridge that is wider in both dimensions – room for the wider freeway below and more lanes on the surface street above. In each case the old bridge will be sliced in half (lengthwise), leaving half of the bridge standing while the other half is demolished and replaced. Once the first new half is complete, traffic will be switched to the new half and the other half will be demolished and replaced. The NB Montana offramp will be eliminated, just as its SB counterpart (Waterford) was eliminated several years ago. The convoluted NB ramps at Getty Center will be replaced by regular 'diamond' ramps, similar to the SB ramps at Getty Center. The SB ramps at Skirball Center will be replaced by a new half- interchange along Sepulveda, just north of Mountaingate; the new SB 'Skirball Center' ramps will be about 1/2 mile south of the Skirball Center bridge. In most areas, the centerline of the freeway will not shift significantly; the freeway will be widened by approximately equal amounts on each side; however, since there is no room for widening on the west side of the freeway through the community of Brentwood Glen (where Church Lane, the only north-south road through the area is right next to the west side of the freeway), the entire widening through this area will be on the east side of the freeway. Since Sepulveda is right next to the east side of the freeway, the hillside east of Sepulveda between Montana and Sunset has been torn down; most of the lanes of Sepulveda will be where the hillside was and the freeway widening will cover most of the existing lanes of Sepulveda.

In February 2013, a replacement on-ramp at Skirball Drive to I-405 SB opened. This new ramp is 2,000 feet south of the Skirball Bridge, and is one of the key roadway improvements in this billion dollar freeway widening project. The new ramp provides greater ramp storage capacity for vehicles entering and exiting I-405, as well as providing dedicated turn-lanes on Sepulveda Boulevard for cars entering and exiting the freeway. The construction also provides new bike routes on Sepulveda Boulevard between Skirball Center Drive and the new southbound on- and off-ramps, as well as a simpler design for the Sepulveda Boulevard/Skirball Center Drive intersection, resulting in a safer intersection.

In April 2013, it was reported that the project was behind schedule. Work on the end sections was proceeding according to schedule, and the project team has achieved a substantial amount of work to date, including new Wilshire on and off-ramps, a new and wider Sunset Bridge, I-10 interchange improvements, Sepulveda Boulevard improvements and a new on-ramp at Skirball. By the end of 2013, the project anticipates completing all bridges and utility work will be nearly complete with project ramps, underpasses, soundwalls and retaining walls. However, structural failure of miles of new sound walls that had to be demolished and rebuilt, a legal wrangle over the placement of ramps near the Getty Center and the complex logistics of finding and relocating more than a dozen utility lines under Sepulveda Boulevard have created delays. Tthe project is now slated to take at least a year longer than first anticipated and cost about $100 million more than the originally budgeted $1 billion. Officials now aim to complete the bulk of the project by June 2014, with work on the problematic middle segment between Montana Avenue and Sunset Boulevard lasting perhaps until fall 2014. The delays so frustrated Elon Musk of SpaceX that he donated $50K to an advocacy group (although some reports made it seem as if he donated to speed up construction).

In June 2013, it was reported that the construction project is reportedly $100 million over budget and to cover the cost overrun the Metro board asked staff to look into implementing a congestion pricing program for the 405 HOV lanes.

In August 2013, it was reported that Metro is seriously exploring the idea of a subway/expressway tunnel(s) under I-405 freeway. Theproject has been fast-tracked; in fact,the transit agency could be looking for funding partners within a year. Work could begin within 2 to 3 years. To build a tunnel or two of them under the freeway it could take 4 to 5 years. The funding would be from a private-public partnership which could involve big international construction and financial companies. Without such a Public Private Partnership (P3) this would have taken 20 to 30 years to pull off. The estimated cost of such a project is in the area of $10 Billion. There is Measure R tax money of one billion that could be used. The other 9 would come from private investors (P3) who would get their money back from expressway tolls if such a roadway is part of the project and/or fees for subway service. The present thinking is a train/expressway system that uses two tunnels or one very large one. The first phase would be through the 10 mile Sepulveda Pass, but it would eventually be expanded from Sylmar, in the San Fernando Valley, all the way through to LAX. That would be a 28 mile system. It could be anywhere from 60 to 90 feet below the surface. Given the steep incline and decline in the pass distances would vary from one part to another since trains need to run on a flat surface. The diameter of a tunnel might be 60 to 70 feet depending on whether there is one or two. Unlike the tunneling done for the Red Line the burrowing equipment is much different and considerably improved than when our first subway was built. Burrowing so far underground would also limit disruption to construction weary residents in the pass. There are no fault lines to present quake problems.

In early November 2013, work on the Wilshire ramps was completed and all on- and off-ramps were opened. In late November, the Montana offramp from the NB I-405 was permanently closed (and its removal was started).

In late May 2014, the HOV lanes opened for service, although landscaping, signage, and retaining wall work still remained. Caltrans took the opportunity to provide some statistics on the project. Enough concrete was used on the project to build four Staple Centers, enough dirt was moved to fill 100,000 dump trucks and enough rebar installed to build 15,000 Volkswagen beetles. They also provided the following summary of the improvements:

In November 2016, it was reported that the Metropolitan Transportation Authority has agreed to pay nearly $300 million more to the contractor of the I-405 Freeway widening project, capping a years-long dispute over responsibility for schedule delays, design changes and cost overruns. The settlement will push the cost of the controversial Sepulveda Pass project above $1.6 billion, about 55% higher than the original budget. The $297.8-million agreement follows years of disagreements between Kiewit Corp. and Metro over how the freeway widening was managed. Kiewit has said in legal filings that Metro’s repeated changes to the project’s design and failure to identify and relocate utilities added significantly to delays.

In March 2015, there were reports that the net improvements from the I-405 Sepulveda Pass project were negligible. A traffic study by Seattle-based traffic analytics firm Inrix reported that auto speeds during the afternoon crawl on the NB I-405 post-project are the same or slightly slower as pre-project; in fact, the 35-minute tangle between the 10 and the 101 is actually a minute longer. SB I-405 is so bad, post-improvements, that when Caltrans issues its "worst bottleneck" rankings in August, unofficial data suggest that the 10-mile stretch of I-405 between the Valley and the Westside could be the worst freeway segment in California. The problem is that a number of studies have shown that carpooling is declining even as carpool lanes are added, often to the exclusion of other major transportation projects.
(Source: LA Weekly, 3/4/2015)

In June 2015, the results of another study were reported. This study was commissioned by Metro from Systems Metric Group and was the first to compare traffic flow on I-405 before and after the Sepulveda Pass project that added a northbound carpool lane, rebuilt and widened bridges and on/off ramps and made other key improvements. The study showed that: (•) The number of Freeway Service Patrol reported accidents has dropped, with 15% fewer Freeway Service Patrol reported accidents in February 2015 compared to Feb. 2009; (•) The afternoon weekday rush hour now runs from 3 p.m. to 8 p.m. compared to 2 p.m. to 9 p.m. before the project, showing that traffic is at its most congested for two less hours on weekdays; (•) Vehicle capacity on northbound I-405 has increased from 10,000 vehicles per hour to 11,700 vehicles per hour at peak times, a 15% increase in vehicle capacity and 30+% increase in people traveling on this section of I-405; (•) Total travel times are slightly lower between I-10 and US 101 except during the peak of the afternoon commute (about 4:30 p.m. to 6:30 p.m.) when travel times are slightly higher, due in part to a bottleneck backing up traffic further north at the I-405 and Route 118 interchange; (•) Travel times on the NB 405 vary less, making travel times are more predictable; and (•) Traffic on major streets near I-405 — including Sepulveda, Sunset, Santa Monica, Pico and Ventura — is 20 to 25% lower since the end of construction. However, the study also showed that commute times during rush hours increased by about a minute, due to a well-documented phenomenon called "triple convergence." People who might have otherwise decided to travel by a different mode, a different route or at a different time make the decision to use the newly expanded freeway based on the assumption that it has improved. It's called "induced demand." So even though Northbound lanes of the freeway can now handle 15% more traffic every hour - that many more cars are now clogging it. Unfortunately, it is hard to factor in that "induced demand" when predicting traffic flows in an expansion project like the I-405 improvement. In its report, Metro said congestion would have increased 36% if the project hadn't been completed.

I-405/US 101 Interchange Improvements (~ LA 39.043 to LA 39.757)

In September 2000, the California Transportation Commission considered a proposal (TCRP Project 51) to add an auxiliary lane and widen the ramp through the I-405/US 101 freeway interchange in Sherman Oaks (~ LA 39.043 to LA 39.757). For phases 1 and 2, the request was for $4 million, with a total estimated cost of $34 million. The phase 3 request was $4.2 million. Phase 1 added a northbound auxilliary freeway lane from Mulholland Drive to Greenleaf Avenue, and was completed around January 2003. The third phase was completed in 2004 and widened the eastbound connector to the US 101 to two lanes. The third phase involves permanently closing the ramp that loops motorists from eastbound Ventura Boulevard onto the northbound I-405 near the Sherman Oaks Galleria. The reconstructed approach routes motorists onto southbound Sepulveda Boulevard and onto Greenleaf Avenue, where they will either drive through a tunnel under the freeway and onto the NB I-405, or stay in the right lane and connect to US 101. It was completed in late 2007.

[SB 405/101 IC]There is also work afoot to address another problem at that interchange -- specifically, the connector between southbound I-405 and the northbound US 101. This might involve construction of an elevated two-lane connector. There are five options currently under consideration, some of which could affect nearby homes or take out part of the Sepulveda Basin wildlife refuge. The connection between two freeways is now just one lane and often backs up on I-405. The project would build a two-lane connector across the Sepulveda Dam spillway, and could possibly include changes to southbound I-405 and the southbound US-101 interchange, and the Burbank Boulevard on-and-off-ramps. Built in the 1950s, the freeway connector was designed to handle up to 1,500 vehicles an hour but now has been swamped with 1,790 autos per hour by 2008. By 2015, morning rush hours are expected to draw up to 2,075 vehicles per hour to the freeway connector as the state population increases. One of the three possible alternatives reconstructs the Burbank Boulevard on-ramp to southbound I-405 to pass beneath the new two-lane connector, at an estimated cost of $86.4 million. However, Burbank Boulevard would lose access to both directions of US 101. As a result, the Los Angeles Department of Transportation opposes the plan. Closing that freeway access will send traffic farther down to Van Nuys Boulevard or through the congested intersection of Sepulveda and Burbank boulevards, said Ken Husting, a senior transportation engineer with LADOT. With this alternative, LADOT engineers want to see other roadway improvements to increase mobility, such as building a full interchange at Hayvenhurst Avenue to US 101. The other alternatives stretch into the 225-acre Sepulveda Basin wildlife refuge - home to various species of birds, from burrowing owls to red-tailed hawks and Canada geese - within the Sepulveda Flood Control Basin. A second proposal, estimated at $117 million, maintains access to US 101 from Burbank Boulevard, but it requires a new loop on-ramp that encroaches on 2.64 acres of wildlife refuge sitting north of Burbank Boulevard and west of I-405. The plan also requires reconstruction of the bridge between Burbank Boulevard and I-405. A third alternative, costing about $88.8 million (and supported by Homeowners of Encino) leaves access to US 101 open from Burbank Boulevard but takes 2.92 acres of the wildlife refuge. This plan excludes reconstructing an existing overcrossing between Burbank Boulevard. The Army Corps of Engineer oppose the 2nd and 3rd alternatives, as do environmental groups. The plans will be discussed at the June 2008 CTC meeting.

In September 2008, the CTC considered the above project for future consideration of funding. The cover information noted that the project will replace the existing connector by constructing a new connector/bridge over the Sepulveda Dam. The project is not fully funded. The project is programmed in the 2008 State Transportation Improvement Program with regional improvement program shares for $7,010,000 for environmental. The total estimated project cost is $165 million. Construction is estimated to begin in Fiscal Year 2013-14, depending on the availability of funds.

In April 2012, it was reported that widening and retrofitting of the Sepulveda Overpass was going to begin in May 2012. For about a year, left turns from Fiume Walk and the Southbound Valley Vista off-ramp onto northbound Sepulveda will be restricted, and left turns from northbound Sepulveda onto Fiume Walk will also be restricted. Additionally, the left turn pocket onto the southbound Valley Vista on-ramp will be shortened and Sepulveda will go to two lanes in each direction near the overpass. Meanwhile, two crosswalks will be eliminated—the crosswalk across Sepulveda at Fiume Walk and the crosswalk across Fiume which, along with sidewalk on the west side of Sepulveda, will close three months after the start of construction.

Naming Naming

This route is named the "San Diego" Freeway; the first portion opened in 1957; the last in 1969. It was named by the State Highway Commission on November 18, 1954. San Diego refers to the eventual southern terminus of the route (after all merges). The name refers to Saint Didacus of Alcalá, a Franciscan saint of the 15th century. The bay was named by Vizcaíno in 1602, the mission in 1769, the county in 1850 and the new city in 1856. The name was likely given to encourage people to take the I-405 bypass of downtown to go to San Diego (connecting with I-5 to the S).

The portion of I-405 from just S of San Diego Creek (South Fork), just S of Route 133 and San Diego Creek, North Fork, NW of Harvard Ave) ( ~ ORA 1.525 to ORA 6.459) in the County of Orange is named the "James Mitchell “Mitch” Waller Memorial Highway". It was named in memory of James Mitchell “Mitch” Waller, who was born in September 1959, in Dallas, Texas. In 1965, Waller and his family moved to Huntington Beach, California, where he began his education. Waller joined the Boy Scouts of America as a Cub Scout in his early school years and continued to participate in the organization as a Boy Scout through high school, earning the prestigious rank of Eagle Scout. Waller graduated from Edison High School in 1977. He continued his education at the University of California, San Diego and graduated in 1983 with a bachelor of arts degree in Biochemistry and Cellular Biology and a minor in Economics. Waller attended the Criminal Justice Training Center at Golden West College, after which he began his career in law enforcement with the City of Westminster Police Department in 1984. While continuing his duties with the City of Westminster Police Department, Waller attended Chapman University School of Law in 1995. He completed his juris doctor degree and passed the California Bar in 1999. In 2003, he was selected to attend the Federal Bureau of Investigation National Academy in Quantico, Virginia. As a community leader, Waller rose through the ranks to become Chief of Police for the Westminster Police Department. He served the law enforcement and safety communities for 27 years. Waller remained committed to the Westminster community and worked to develop positive staff relations, communications, and infrastructure. Under his direction, the new Westminster Police Department building was completed in 2011, on time and under budget—an accomplishment of which he was very proud. Waller accepted an appointment to the office of the Westminster City Manager in 2011, and he retired in 2012. In his neighborhood in the community of Mission Viejo, Waller was known for generosity with both his time and talents. He was very active in his daughter softball teams, supporting them with everything from coaching assistance to first aid. For his son, Mitch assisted with his training for the high school cross-country and track teams, always there to offer his encouragement and support. The exemplary life of Mitch Waller ended tragically in an accident on the morning of Friday, June 28, 2013, at 53 years of age, while he was cycling with his good friend in the bike lane on Route 133, heading toward Laguna Beach—a favorite destination. Named by Assembly Concurrent Resolution (ACR) 65, Res. Chapter 169, Statutes of 2015, on September 10, 2015.

The portion of I-405 northbound in the County of Orange between Magnolia Street and Brookhurst Street (~ ORA 15.210 to ORA 13.780), is designated the "Lt. Colonel Nguyen Thi Hanh Nhon’s Disabled Veterans Memorial Highway". It was named in memory of Nguyen Thi Hanh Nhon, who was born in 1927 in Hue, Việt Nam, a daughter of a field marshal of the Nguyen Dynasty. Ms. Nguyen was married to Ly Nhut Huong, a businessman, and was the mother of nine children. In 1950, when the French came to Việt Nam and formed the Corps of Female Assistants, consisting of office secretaries, nurses, and social workers, Ms. Nguyen enlisted and served in the corps. When the American forces arrived in Việt Nam, this corps became the Corps of Female Soldiers and served under the regime of the South Vietnamese Armed Forces until 1975. At the time, Ms. Nguyen served as a Lieutenant (Lt.) Colonel of the Air Force of the Republic of Vietnam at the Air Force Headquarters at Tan Son Nhut Airbase. After the fall of Saigon in 1975, Lt. Colonel Nguyen was imprisoned in a reeducation camp for nearly five years and suffered hard labor in the forest with access to little food and water, and lived in horrific conditions. After her release, she had little options left but to find work in any capacity, from selling ice cream to selling home construction materials to support her family. In 1990, one of her sons sponsored her to come to the United States via the Humanitarian Operation under the Orderly Departure Program and she became a resident of the City of Garden Grove. In 1991, Lt. Colonel Nguyen joined the Mutual Society of Political Prisoners and served as its Vice President to help those in Việt Nam who qualified under the Humanitarian Operation to come to the United States. Once those qualifying under the Humanitarian Operation arrived in the United States, Lt. Colonel Nguyen helped them find work and housing, enrolled children in schools, and more importantly, helped them to adjust to life in America. These community efforts were instrumental in providing new immigrants with the tools to acclimate and become self-sufficient. In 1994, when the Humanitarian Operation ended, Lt. Colonel Nguyen and the group organized a Humanitarian Operation Mutual Society for Việt Nam Wounded Veterans, of which she became president in 2006. Through this organization, Lt. Colonel Nguyen assisted disabled Veterans of the Republic of Vietnam who were still in Việt Nam facing financial difficulties and raised awareness to help the wounded soldiers in Việt Nam. In 2006, as the needs to serve many disabled veterans in Việt Nam increased, Lt. Colonel Nguyen organized the “Cam On Anh” Annual Concert in the City of Garden Grove, California, to raise funds to send money back to Việt Nam for disabled veterans. Over the past 10 years, Lt. Colonel Nguyen has helped serve over 22,000 disabled veterans of the Army of the Republic of Vietnam. In addition to her work in support of veterans, Lt. Colonel Nguyen helped educate students about the impacts of the Vietnam War and contributed her life story to the University of California, Irvine Vietnamese American Heritage Foundation Oral Histories Project. Lt. Colonel Nguyen was an active member of several community-based organizations dedicated to improving the lives of Vietnamese Americans in the County of Orange and throughout the State of California. On April 18, 2017, Lt. Colonel Nguyen passed away at the age of 90, leaving a strong legacy of community service for the residents of California’s 34th Senate District. Named by Senate Concurrent Resolution 60, Resolution Chapter 178, 9/22/2017.

The portion of I-405 between just SE of the Route 22 interchange and Bolsa Chica Road and the San Gabriel River overcrossing, just NW of I-605 interchange (~ ORA 20.4 to ORA 24.178) in the County of Orange is named the "Kevin Woyjeck Memorial Highway". As the son of a captain in the Los Angeles County Fire Department, the grandson of a smokejumper, and the eighth firefighter in the Woyjeck family, Kevin Woyjeck knew from an early age that he wanted to be a firefighter. Kevin grew up in Seal Beach, California, and attended McGaugh Elementary School in Seal Beach and McAuliffe Middle School and Los Alamitos High School, both in Los Alamitos, California. He spent every summer for nine years as a Seal Beach Junior Lifeguard. When he was 15 years old, Kevin joined the Los Angeles County Fire Department Explorer Program. Kevin became an emergency medical technician while in high school and worked on an ambulance crew shortly after graduating. Kevin had extensive training as a firefighter, having taken firefighting classes at Santa Ana College, El Camino College Structure Fire Academy, and the Department of Forestry and Fire Protection Academy in San Luis Obispo. Kevin also spent a season in South Dakota, where he joined the Johnson Valley Volunteer Fire Department and performed indirect wildland firefighting for the South Dakota Wildland Fire Division as part of a Type 2-IA Handcrew. In April 2013, Kevin was honored to join the Granite Mountain Hotshots, an elite crew of 20 young men in top condition, based in Prescott, Arizona, who had direct wildland firefighting responsibilities with the ability to provide service anywhere in the nation. After successfully fighting fires and saving lives and property in New Mexico and Arizona, Kevin and the other members of the crew responded to an out-of-control fire in Yarnell, Arizona, on June 30, 2013. Nineteen of the twenty young men in the Granite Mountain Hotshots tragically lost their lives in the fire, including Kevin. Named by Assembly Concurrent Resolution (ACR) 100, Res. Chapter 116, Statutes of 2016 on August 16, 2016.

The portion of I-405 from Cherry Avenue south to Atlantic Avenue in the County of Los Angeles (~ LA 4.867 to LA 6.071), is named the "Signal Hill Police Officer Anthony “Tony” Giniewicz Memorial Highway". It was named in memory of Officer Anthony “Tony” Giniewicz, who faithfully served the Signal Hill Police Department and the residents of the City of Signal Hill as a police officer assigned to patrol operations. Officer Giniewicz was shot in the line of duty by three gang members while responding to a robbery in progress at a restaurant in the City of Long Beach on February 19, 1985. Officer Giniewicz was paralyzed from the chest down as a result of his wounds and remained in poor health until passing away as a result of complications on December 7, 2011. Named by Senate Concurrent Resolution 84, Resolution Chapter 89, on July 9, 2014.

The portion of I-405 from South Western Avenue to Redondo Beach Boulevard in the County of Los Angeles (~ LA 14.476 to LA 16.889) is named the "Louis Zamperini Memorial Highway". Louis Silvie Zamperini was born in January 1917, in Olean, New York, to Italian immigrants Anthony Zamperini and Louise Dossi. Zamperini’s family moved to Torrance, California, in 1919. Louis Zamperini learned to box before he became a runner. His father taught him how to box so he could defend himself against bullies who taunted him because he could not speak English. Pete Zamperini, his older brother, encouraged him to try out for the track team at Torrance High School. Louis Zamperini set the national high school record in the mile at the Los Angeles Memorial Coliseum in 1934, earning him the nickname of the “Torrance Tornado.” His record time of 4 minutes, 21.2 seconds stood for 20 years. His schoolboy exploits on the track team earned him a scholarship to the University of Southern California. Two years later, in the 5,000-meter Olympic trials at Randalls Island in New York, Louis Zamperini finished in a dead heat with Don Lash, the world-record holder, which qualified him for the 1936 Olympics in Berlin as a teenager, alongside such Olympians as Jesse Owens, Ralph Metcalfe, and Mack Robinson, the older brother of Jackie Robinson. Two years later, in 1938, Louis Zamperini set a national collegiate mile record of 4:08.3, which stood for 15 years. He subsequently graduated from the University of Southern California, and not long after that, when World War II broke out, he enlisted in September 1941 in the United States Army Air Corps and became a bombardier on a Consolidated B-24 bomber in the Pacific theater of operations. During a search and rescue mission to save a downed pilot, Louis Zamperini’s airplane crashed due to mechanical failure, and he and two other airmen were the only survivors of the 11-man crew on board the airplane. One of the men died after 33 days, and Louis Zamperini and the other airman were stranded on a raft for a total of 47 days before washing ashore on a Pacific island and being taken as prisoners of war (POWs) by the Japanese. Louis Zamperini was tortured for the next two years and was only released and returned to the United States after the end of the war in the Pacific in 1945. After the war, he founded a camp for troubled youths called the Victory Boys Camp. Louis Zamperini married in 1946 and remained married until his wife's death in 2001. His marriage became strained because of his nightmares reliving his World War II experiences, and he began drinking heavily, trying to forget his experiences as a POW. In 1949, at the encouragement of his wife, Louis Zamperini reluctantly agreed to attend a Billy Graham crusade. Graham’s preaching reminded him of his prayers during his time on the life raft and his imprisonment, and Zamperini recommitted his life to Christ. Following this, he forgave his Japanese tormentors, and his nightmares ceased. Louis Zamperini was a defiant, resourceful, and determined man. He became an Olympic athlete and survived a plane crash, being lost at sea, and the worst of a Japanese prisoner-of-war camp during World War II. In 1998, he carried the Olympic torch at the Winter Olympics held in Nagano, Japan. He also spent the last 65 years of his life sharing his faith and his philosophy of life with as many audiences as would invite him to speak. In his talks, he included the concepts of forgiveness, hardiness, preparation, and a new life in Christ. Louis Zamperini was also quick-witted, fun-loving, humble, and extremely caring of other people. On July 2, 2014, Louis Silvie Zamperini passed away at his home in Los Angeles, California, at 97 years of age. His dramatic life story (Olympian and World War II POW) has been told in various books, including the 2010 biography “Unbroken: A World War II Story of Survival, Resilience, and Redemption,” by Laura Hillenbrand and the December 2014 film “Unbroken,” directed by Angelina Jolie. Named by Assembly Concurrent Resolution (ACR) 157, Res. Chapter 122, Statutes of 2016 on August 16, 2016.

The portion of I-405 between Rosecrans Avenue and El Segundo Boulevard in the County of Los Angeles (~ LA 19.226 to LA 20.22) is named the "Hawthorne Police Officer Andrew Garton Memorial Highway". It was named in memory of Hawthorne Police Officer Andrew Garton, a seven-year veteran of the Hawthorne Police Department, who died on May 26, 2011 from injuries sustained in a motorcycle crash during the funeral procession of another fallen officer. Officer Garton, 44, was the first Hawthorne officer to die in the line of duty in the department’s 89-year history.

Andrew served as Vice President of the Hawthorne Police Officer’s Association and as Treasurer of the Hawthorne Police Officer’s Association Political Action Committee. Andrew was a long-time member of the Hawthorne SWAT Team, and an accomplished motor vehicle and traffic investigator. He was also active in both scouting and coaching youth baseball. For those who knew him, he was both a mentor and a friend. Named by Assembly Concurrent Resolution 100, Resolution Chapter 109, on September 4, 2012.

Before 1954, this route was named the "Sepulveda Freeway". Sepulveda refers to the boulevard that the route parallels, which was named for the Sepulveda family of early Los Angeles.

The portion of Route 405 from Howard Hughes Parkway to Mulholland Drive in the County of Los Angeles (~ LA 24.704 to LA 37.011) is named the "Nathan Shapell Memorial Highway". This segment was named in honor of Nathan Shapell, a builder of lives who was dedicated to helping others less fortunate. A survivor of the Holocaust, he was determined to not only rebuild his own life, but to help others rebuild theirs. For more than five years after World War II, he built a community for thousands of displaced people and survivors of the camps before emigrating to the United States in the early 1950s. Shapell built a highly successful real estate development company that is recognized as an industry leader and highly respected as a role model for corporate philanthropy. He dedicated a major portion of his life to public service. He was a past President and Executive Board Member of the American Academy of Achievement and served as a Member of President Reagan's Private Sector Survey on Cost Control. He founded and cochaired Building a Better Los Angeles, a one-time project that raised over $1 million for the homeless. In 1987, he accepted the position of President of D.A.R.E. America, a renowned drug abuse resistance education program. In 1992, Governor Pete Wilson appointed him to serve as a member of the California Competitiveness Council and develop recommendations to revitalize California's economy. Nathan Shapell's greatest public contributions were made through his 29 years of service on California's "Little Hoover Commission." As chairman for an unprecedented 18 years of this one-of-a-kind commission, he helped save taxpayers billions of dollars and improve the lives of hundreds of thousands of Californians in areas that include nursing home operations, children's services, property management, transportation, the Medi-Cal program, and public education. Nathan Shapell's commitment to service on behalf of the public was recognized in 1986 when Santa Clara University bestowed upon him an honorary Doctorate of Public Service degree. In 1987, Tel Aviv University awarded Mr. Shapell a Doctor Philosophiae Honoris Causa. He chronicled the early years of his life in his book, "Witness to the Truth". Mr. Shapell lived in Beverly Hills until his death on March 11, 2007. (What is interesting, perhaps because it was a rush job, is that the resolution doesn't mention that Mr. Shapell built loads and loads of homes in areas that were developed due to the freeways, such as the S.F. Bay area and Porter Ranch. Some might say that it would have been more appropriate to designate Route 118 between Balboa Blvd and Topanga Canyon Blvd in his honor. However, also not mentioned in Shapell's Jewish philanthrophy, which is perhaps the basis for having the route on the heavily Jewish westside, ending at Mulholland, where the Skirball Center, American Jewish University, and Stephen S. Wise Temple are located) Named by Assembly Concurrent Resolution (ACR) 73, Resolution Chapter 148, on 10/2/2007.

The portion of Route 405 from Venice Boulevard to National Boulevard in the City of Los Angeles (~ LA 27.991 to LA 29.183) is officially designated the "CHP Officer Philip Dennis Ortiz Memorial Highway" It was named in memory of CHP Officer Philip Dennis Ortiz. Ortiz was born June 27, 1961, in Santa Monica, California. He graduated from Santa Monica High School in 1979 and attended Santa Monica City College. Prior to joining the California Highway Patrol (CHP), Philip worked for a local supermarket; however, he always had a dream of becoming a CHP Officer. On December 23,1982, CHP Officer Philip Dennis Ortiz, badge number 10428, graduated from the CHP Academy and was assigned to the central Los Angeles area office. After more than seven years of service in the central Los Angeles area, Officer Ortiz was transferred to the west Los Angeles area, where he spent the remainder of his career. Officer Ortiz performed several duties over the course of his career, some of which included a motorcycle officer, a motorcycle officer in charge of training the officers who successfully passed motor school, a weapons/range officer, a physical methods of arrest (PMA) instructor, and protective services detail (PSD). On June 22, 2010, CHP Officer Philip Dennis Ortiz pulled a vehicle over for a high occupancy vehicle (HOV) lane violation. While approaching the vehicle, another car was driving along the shoulder and struck Officer Ortiz and his motorcycle. Officer Ortiz was transported to the Ronald Reagan UCLA Medical Center where he remained until his passing almost two weeks later. Officer Ortiz is admired for his professionalism, dedication, honesty, loyalty, respect, courage, and "espirit de corps." He consistently represented the best of the CHP and was an outstanding role model. Named by Assembly Concurrent Resolution 41, Resolution Chapter 52, on July 15, 2011.

The freeway interchange between Route 105 and Route 405 (~ LA R21.11) is officially designated the "Sadao S. Munemori Memorial Freeway Interchange". Sadao S. Munemori, an American of Japanese ancestry, served in the 100th Infantry Battalion of the US Army, a unit composed mainly of Japanese-Americans from Hawaii. This battalion later became part of the 442nd Regimental Combat Team, the most highly decorated unit of World War II for its size and time in combat. In March 1945, Private Munemori and his company were ordered back to Northern Italy to join forces in the final push against the Gustav Line, a fortified German position that had held up the Allied advance for more than four months. On April 5, 1945, the company came under murderous fire, and its commander, Lt. David Novack, and squad leader, Staff Sgt. Kei Yamaguchi, were severely wounded and Private Munemori took command and single handedly, using grenades, knocked out two enemy machine guns, giving his own life to save two of his comrades when he used his own body to shield them from an exploding enemy grenade. Named by Senate Concurrent Resolution No. 41, Chapter 131, in 1994.

The I-405/I-10 Interchange (~ LA 29.484) is named the "Marilyn Jorgenson Reece Memorial Interchange". It was named in honor of Marilyn Jorgenson Reece, who was born and raised in North Dakota and earned a bachelor's degree in civil engineering from the University of Minnesota in 1948. Ms. Reece moved to Los Angeles with her parents shortly after graduation in 1948, and went to work for the State Division of Highways, which later became the Department of Transportation, as a junior civil engineer in Los Angeles. After six years of experience required to sit for the Professional Engineers Exam, Marilyn Jorgenson Reece became the state's first fully licensed female civil engineer in 1954. In 1962, Marilyn Jorgenson Reece received the Governor's Design Excellence Award from Governor Pat Brown for designing the I-10/I-405 interchange. Ms. Reece became the Division of Highway's first woman resident engineer for construction projects shortly after receiving that award. The three-level I-10/I-405 interchange designed by Marilyn Jorgenson Reece opened in 1964 and was the first interchange designed in California by a woman engineer. Urban critic Reyner Banham, author of <I>Los Angeles: The Architecture of Four Ecologies</I>, admired the wide-swinging curved ramps connecting the two freeways, and wrote that the I-10/I-405 interchange "is a work of art, both as a pattern on the map, as a monument against the sky, and as a kinetic experience as one sweeps through it". During her 35-year career, Marilyn Jorgenson Reece's projects included serving as senior engineer for the completion of Route 210 through Sunland in 1975—at the time, the largest construction project the Department of Transportation had ever awarded—at $40 million. After retiring in 1983, Marilyn Jorgenson Reece taught engineering classes at Cal State Long Beach; and during Women's History Month in 1983, the Los Angeles City Council honored Marilyn Jorgenson Reece for making significant contributions to the city. In 1991, Marilyn Jorgenson Reece received life membership in the American Society of Civil Engineers. Named by Senate Concurrent Resolution (SCR) 72, Resolution Chapter 96, on 8/15/2006.
