Happy new year to those who celebrate: Be it the new Jewish New Year, or the new US Government Fiscal New Year. We have a continuing resolution; we don’t have a shutdown—this is good news. And so: Happy New Year.
September has been muchly getting ready for the new season of the California Highways: Route by Route podcast. I’ve been busily writing episodes. This season, we’re covering Route 1 and Route 2, and I’ve written six episodes covering Route 1 from Orange County through and including San Francisco. Next to write is the episode on the Golden Gate Bridge. A side effect of this is that I’ve discovered a number of interesting historical articles and sources. Some will be in the entries for the episodes themselves, but I’ve also saved some to the headlines list so that I’ll go through them again to update the pages. These articles will be marked in the headlines list with the Historical (Ħ) flag. I’ll soon be coordinating with Tom to start recording episodes. If you think you might know a good interview subject for the following segments of Route 1, please let me know ASAP: 2.01 Orange County; 2.02 Los Angeles County; 2.03 Ventura and Santa Barbara County; 2.05 Monterey and Santa Cruz; 2.06 Pacifica and San Francisco.
I also expect to get back to working on highway page updates, now that I have a headline post to go through. First will be catching the legislative updates, as the session has concluded and bills sent to the governor for signature. My goal is to have the next update round cover September and October.
No roadtrips on the horizon, although there will be a So Cal Games Day in October.
Well, you should now be up to date. Here are the headlines that I found about California’s highways for September:
[Ħ Historical information | ＄ Paywalls, ＄＄ really obnoxious paywalls, and ∅ other annoying restrictions. I’m no longer going to list the paper names, as I’m including them in the headlines now.

- Stretch of highway in California named after slain Indian-origin police officer (The Hindu). To honour a fallen national hero, a stretch of a highway in the US state of California has been named after 33-year-old Indian-origin police officer Ronil Singh who was shot and killed by an illegal immigrant in 2018. The stretch of Highway 33 in Newman was dedicated on Saturday to Mr. Singh from the Newman Police Department, the Modesto Bee newspaper reported. Signage proclaiming the “Corporal Ronil Singh Memorial Highway” stands at Highway 33 and Stuhr Road.
- State allocates more than $39 million to highway projects in Mendocino County (Fort Bragg Advocate-News). The California Transportation Commission allocated more than $3.1 billion for projects described as “improving the state’s transportation infrastructure, making it safer, more sustainable and more reliable,” the California Department of Transportation announced this week. According to a Caltrans press release, “the allocation includes nearly $1.8 billion in funding from the federal Infrastructure Investment and Jobs Act of 2021and almost $200 million in funding from Senate Bill (SB) 1, the Road Repair and Accountability Act of 2017.” […] The projects funded in Mendocino County were listed as:
- ＄ Napa has bridge replacements planned – drivers beware (Napa Valley Register). Here is a tale of five bridges to be replaced in coming years — one smack in the city of Napa, the others farther afield — and the traffic impacts that might result. Don’t take these bridges for granted even though they cross small creeks instead of mighty rivers. You can’t get here from there without them, not without a detour. That leaves the challenge of how to handle traffic while replacement work is underway. Caltrans and Napa County are already making plans for bridge replacements that are to start in 2024 and 2025, giving plenty of advanced warning. Here’s a preview of what’s to come:
- Roundabout coming to State Route 121 and Eighth Street East intersection in Sonoma (Sonoma Index Tribune). Elected officials met at the intersection of State Route 121 and Eighth Street East on Thursday to celebrate $1.5 million in new federal funding for a roundabout to replace the current T-intersection. Leaders of the proposed roundabout project — and an accompanying bike lane — say its introduction will help increase vehicle safety, but it will require drivers to operate outside of the box — and into a circle. “During the recession years ago, (the roundabout) fell off in the shop plan,” First District Supervisor Susan Gorin said. “Sonoma County Transportation Authority) were working on the roundabout at the four corners down there. And so it just made sense for them to continue their work with Caltrans on the design.”
- September 4: This Date in Los Angeles Transportation History (Metro’s Primary Resources). 1948: Lankershim Boulevard opens to traffic under a newly completed Hollywood Freeway overpass as part of the “Barham-to-Vineland” segment of US-101. Much of the construction involved overpass accommodation for both the Pacific Electric rail lines and six lanes of freeway.
- Caltrans completes $8.7 million SB 1-funded project to repair State Route 14 in the Mojave Desert (The Ridgecrest Daily Independent). Caltrans today announced the completion of the Freeman III Project, an $8.7 million State Route 14 project that repaired 15 lane miles of pavement, stretching from one mile north of Red Rock Canyon Road to three-and-a-half miles south of the Freeman Gulch Bridge. The project was fully funded by Senate Bill (SB) 1, the Road Repair and Accountability Act of 2017. The contractor Griffith Company used a sustainable partial depth recycling (PDR) technique, which supports Caltrans goal of leading climate action by recycling existing pavement. During the PDR process, crews dug out current road material in localized sections and recycled it, combining the material with Hot Mix Asphalt (HMA). The HMA was then reapplied to the excavated areas. Crews then laid a two-and-a-half-inch layer of Rubberized Hot Mix Asphalt on top of the PDR to restore the high-quality ride and serviceability of the existing roadway.
- OHLA Converting Expressway Into Freeway in California (Construction Equipment Guide). OHLA USA Inc. began work on Phase 1 of the California Department of Transportation’s (Caltrans) SR-71 Expressway to Freeway Conversion Project in spring 2021 and crews are hard at work to deliver it by summer 2025. The $174.544 million project, taking place in the city of Pomona, covers 2.7 mi. between SR 71/I-10 interchange (Mission Boulevard) and the Los Angeles/San Bernardino County Line. Phase 2 of the project, the North Segment, covers the area from the SR 71/I-10 interchange to Mission Boulevard. Construction is expected to begin next spring, with a completion in spring 2027. Thus far, OHLA USA has completed Stage 1 of the roadway jointed plain concrete pavement (JPCP) roadway project, which included demolition of existing AC/JPCP, excavation and backfill of base, placement/revisions to existing drainage systems and placement of new JPCP.
- Memorial sign in Tehama County honors fallen Caltrans workers (Corning Observer). In honor of the 15 Caltrans District 2 workers who have died in the line of duty, memorial signs have been installed at the Interstate 5 J.C. Helmick rest area in Tehama County and the Collier rest area in Siskiyou County. Statewide, memorial signs are being designed, manufactured, and installed by Caltrans workers to recognize the 191 highway workers who have been killed on the job since 1921. Every year, Caltrans employees, family members of fallen workers, and community members throughout California gather to honor these workers and to promote safe driving campaigns. “Safety is Caltrans’ top priority,” said Caltrans Director Tony Tavares. “Lives are literally at stake every day. We hold a sacred duty to remember all the people who have lost their lives working with us, and I implore all Californians to please slow down and move over in every work zone, every time. A life may depend on it.”
- Golden Gate Bridge nears last phase of quake upgrades (Marin I-J). Golden Gate Bridge officials are preparing to launch the final and largest phase of a decadeslong project to make the 85-year-old structure withstand stronger earthquakes. The Golden Gate Bridge, Highway and Transportation District plans to select a construction contractor later this year to begin preliminary work on the estimated $880 million final phase. The project will upgrade the main span and the towers and allow the bridge to withstand a magnitude 8.3 quake, which would be comparable to the destructive 1906 San Francisco earthquake. “For us, we really are going through one of the most important undertakings on this bridge,” said district engineer Ewa Bauer-Furbush. “That’s the project for us.”
- September 6: This Date in Los Angeles Transportation History (Metro’s Primary Resources). 1957: The first unit of the Golden State Freeway opens between the northeast corner of Griffith Park through Glendale to Ash Street in Burbank.
- Tenth anniversary of East Span; Bay Bridge factoids and trolls (The Bay Link Blog). September marks the 10th anniversary of the opening of the San Francisco-Oakland Bay Bridge’s East Span. To celebrate, here are 10 facts about the bridge(link is external). On Sept 2, 2013 — Labor Day — the new East Span was opened to traffic starting about 10 p.m. after a day of ceremonies where then Lt. Gov. Gavin Newsom reenacted the chain cutting that marked the opening of the original Bay Bridge in 1936. The famous Bay Bridge Troll(link is external), rescued from the old East Span made an appearance at the ceremony. The hand-crafted, 18-inch metal troll lived on the old Bay Bridge ever since the span was restored to service after the 1989 Loma Prieta earthquake and was intended to protect the span.
- SR 210 Lane Addition/Base Line Interchange (SBCTA). The SR 210 Lane Addition/Base Line Interchange project, designed to provide increased traffic flow throughout this corridor, will be built as one project. To eliminate the existing bottleneck and provide lane continuity, the SR 210 will be widened from Sterling Avenue to San Bernardino Avenue in the cities of San Bernardino, Highland, and Redlands, as well as an unincorporated portion of San Bernardino County. Base Line Interchange will also be widened from Buckeye Street to Seine Avenue in the City of Highland. The SR 210 Lane Addition and Base Line Interchange Project is entering its final months of construction. Crews have striped the SR 210 lanes to their final configuration between Del Rosa Avenue and the I-10 freeway, adding one mixed-flow lane in each direction between Highland Avenue and San Bernardino Avenue, auxiliary lanes (merge lanes) between Base Line and 5th Street/Greenspot Road, and an acceleration lane at the 5th Street/Greenspot Road eastbound ramp.
- Full Closure of Hwy 20 Scheduled for Omega Curves Project (YubaNet.com). Caltrans is alerting motorists about an upcoming 12-day closure of State Route 20 (SR-20) east of Nevada City for major roadwork on the Omega Curves Project. The full closure will be in effect at two locations starting Sunday, September 24 at 7 p.m. and ending at Noon on Friday, October 6. The first closure will take place in the Lowell Hill segment between the Omega Overlook and Bear Valley. Work is anticipated to finish Sunday, October 1 at 7 p.m. Crews then will move the closure location west to the White Cloud segment between the White Cloud U.S. Forest Service and Campground and Washington Road.
- US: California Highway named after slain Indian-origin cop Ronil Singh (Republic World). A stretch of a highway in the US state of California now bears the name of Ronil Singh, a 33-year-old Indian-origin police officer who lost his life when an illegal immigrant shot him in 2018. The Newman Police Department named the stretch of Highway 33 in Newman ‘Corporal Ronil Singh Memorial Highway’ during a ceremony held last Saturday. A signage was installed near the intersection of Highway 33 and Stuhr Road during the commemoration ceremony, which was held following the community’s Tunnel to Towers 5K walk and run. The martyred officer’s wife, Anamika, their son Arnav, who was just 5 months old when his father was killed, and other family members were at the event.
- 710 Stub Project Management Proposal Goes Before the Council Monday (Pasadena Now). The City Council on Monday will vote on a contract with pointC, LLC for strategic planning and project management services related to the 710 relinquishment area. After years of opposition, and at one support, of a freeway extension through West Pasadena, Pasadena reclaimed 50 acres of the 710 stub in 2022 when Caltrans formally relinquished the stub to the City of Pasadena. In August 2022 the title of the property was transferred to the City. PointC has a proven track record of helping the City achieve successful outcomes related to the 710 relinquishment, according a city report.
- New Grants Given to Humboldt and Mendocino Fish Culvert Projects (Redheaded Blackbelt). Today, U.S. Representative Jared Huffman (CA-02) announced new grants for his district from the FY22 National Culvert Removal, Replacement, and Restoration Grant Program (Culvert AOP Program). Last Wednesday, Huffman visited the site of one of these projects to examine how the award will be utilized and the local impacts. “Undersized and poorly placed culverts are a major impediment to salmon and steelhead trying to reach important spawning grounds,” said Rep. Huffman. “This funding will open miles of habitat for federally protected fish while improving the safety and function of roadway structures – which is increasingly important as we face more frequent flooding due to climate change. It’s a major win-win that will help improve our region for travelers and our iconic species alike.” The grants have been awarded as follows:
- Route 1 Paul’s Slide Update (X/District 5). Crews continue with repairs to #Hwy1 at Paul’s Slide which remains closed between Limekiln State Park and the town of Lucia. An updated design will bring the roadway slightly inland to enhance safety. No estimate at this time for a full reopening of #Hwy1 at Paul’s Slide.
- Sonoma County roundabout project receives $1.5M to improve 121/12/8th Street junction (Local News Matters). Sonoma County’s efforts to make infrastructure improvements in the area has received a boost with $1.5 million in additional federal funding, the office of Rep. Mike Thompson, D-St. Helena, announced. Sonoma County Transportation Authority officials last week received the $1.5 million check from Thompson, to be used on the State Route 121/12/8th Street East Intersection Improvements project. The lawmaker’s office said it secured this funding in the Fiscal Year 2023 government funding package. “The improvements planned for 8th Street and 121 will improve safety and support local and tourist travel,” Sonoma County Transportation Authority Executive Director Suzanne Smith said in a statement.
- ＄ Napa looks at creating safer wine country roads (Napa Valley Register). Soscol Avenue is a bustling Napa city roadway lined with homes, auto showrooms, shopping centers, hotels, noontime taco trucks and businesses. It also is a potential candidate for a traffic safety makeover. Vehicle lanes could be narrowed to make room for better bicycle lanes. High-visibility crosswalks and crossing beacons could be installed. And the Silverado Trail intersection could be “squared up” as near to a 90-degree angle as possible. Welcome to a possible Vision Zero world that prioritizes safety over vehicle speeds. The goal is to eliminate the worst traffic accidents throughout Napa County by 2030. From 2015 to 2021, Soscol Avenue had 174 injury collisions, according to a draft Vision Zero study released by the Napa Valley Transportation Authority. The focus is on the 15 crashes that resulted in death or serious injury.
- ＄Construction on Highway 29 in St. Helena starts Monday (Napa Valley Register). Expect evening traffic delays in downtown St. Helena into early October as Caltrans performs emergency drainage replacement on Main Street, which is also Highway 29/128. The southbound lanes of Main Street between Adams Street and Madrona Avenue will be subject to one-way traffic control between 8 p.m. and 6 a.m. weekdays. Work began Monday and will continue into Oct. 9. Caltrans announced the schedule in a news release issued Friday. The agency stated the work is weather-dependent and “may be extended or rescheduled due to inclement weather.” “Every effort will be made to minimize inconvenience, but construction noise cannot be entirely avoided,” the agency stated. “Caltrans thanks residents for your patience.”

- Sonoma County and Caltrans work to improve traffic jams on Highway 12, Arnold Drive after numerous complaints (Sonoma Index-Tribune). Since Caltrans closed a stretch of Highway 12 on Sept. 5 to replace the Hooker Creek Bridge, drivers have been stuck in traffic jams. The problem compounded on Sept. 6, when tree work reduced traffic to one lane on Arnold Drive just as Caltrans was diverting drivers off Highway 12 toward the Valley’s other major north-south thoroughfare. One driver reported it took 56 minutes to traverse roughly 5 miles from Glen Ellen to Boyes Hot Springs. PG&E was conducting the tree work as part of its routine fire risk remediation, but the county was not privy to the schedule. In an email, Karina Garcia, field representative for First District Supervisor Susan Gorin, said once they were “made aware” of the tree work on Sept. 6, they coordinated with PG&E and the county’s Public Infrastructure department to ensure no more work would occur on Arnold while Highway 12 is closed.
- Transportation For America New survey: 82 percent of voters don’t believe highway expansions are the best solution for reducing congestion (Transportation For America). A new nationwide survey of American voters’ attitudes reveals a significant divide between voters’ attitudes about the best short-and long-term solutions for reducing traffic, versus the actual priorities of their state and local transportation agencies. In 2021 The Washington Post estimated that highway widening and expansion consumed more than a third of states’ capital spending on roads (over $19 billion). These projects were backed by promises to reduce congestion. The public isn’t buying it. The results of a national survey of 2,001 registered U.S. voters—90 percent of whom own a car they drive regularly—underscores a widely shared belief that highway expansion doesn’t work as a short- or long-term strategy for reducing traffic and that we should invest more in other options.
- Newark, Alameda County Get $40M For Infrastructure Projects (Newark, CA Patch). Alameda County has landed $40 million in state funds to support multiple key infrastructure projects including along Interstate Highway 880 in the Tri-City area. The money is part of billions being allocated by the California Transportation Commission for Caltrans projects that are designed to improve safety, reliability, and sustainability along essential travel corridors. […] The CTC funding includes nearly $1.8 billion in federal infrastructure funds and $200 million in funds from the state Road Repair and Accountability Act, passed in 2017. Here is where the money is headed in Alameda County and the rest of the Bay Area:
- ＄ Highway 70 five-lane construction wraps up with ceremony (Chico Enterprise-Record). Since 2010, 55 people have died driving the Highway 70 corridor between Oroville and Marysville. The heavily traveled roadway, up until recently, mostly consisted of two lanes north and south, funneling thousands of vehicles per day into often cramped road conditions leading to a high rate of crashes, many fatal. Going back as far as 2018, Caltrans and local agencies have pushed to secure enough funding to redo the section of Highway 70, expanding its capacity and ideally making it safer for travelers. After years of construction, Caltrans and its partners finally wrapped up the project and held a ceremony Thursday morning acknowledging those who played a part in its completion.
- ＄＄ Caltrans will begin repairs to preserve two historic bridges near Hemet and Lake Elsinore (Valley News). The California Department of Transportation announced in mid-September they will begin working on a $17.9 million bridge retrofit and upgrade project on the Morrill Canyon Bridge near Elsinore and the Strawberry Creek Bridge near Mountain Center in the San Jacinto mountains. The project is an attempt to preserve the two bridges that have been a part of the regions’ history for many years. The Morrill Canyon Bridge is on state Route 74 near the Tenaja Truck Trail. The Strawberry Creek Bridge flows under Highway 74 near Idyllwild and sometimes is a fishing spot for locals. The project to help preserve the bridges was awarded to Beador Construction Company of Costa Mesa. The projects will upgrade the bridges with slab overlays and new guardrail systems and bring lane and shoulder widths…
- Ħ It’s History: Pacific Coast Freeway? | (Dana Point Times). This column has always focused on what was, but now is gone. As my mentor, Doris Walker said and imparted on me, “If things do not change, what would I write about?” Change in Dana Point has always been long in coming. And when it does, it is met with resistance, and sometimes it is stopped. A case in point is the “Pacific Coast Freeway.” In 1956, President Eisenhower signed the Federal-Aid Highway Act. It was then boasted as a $1.1 billion fund and called “the greatest public-works program in the history of the world.” And every state wanted a piece of that pie. Orange County was no different. In June 1957, members of the California State Highway Commission studied a proposal for the construction of the Orange Coast Freeway, an inland route to replace Pacific Coast Highway. It was to connect Long Beach to the San Diego Freeway, under construction at the time, at Capistrano Beach. It was scheduled to cut through Newport Beach at 16th street and go through Laguna Beach.
- Ħ Newport Beach in the Rearview Mirror – “The Freeway That Almost Destroyed Newport” (Stu News Newport). Bill Lobdell looks at people and events – famous and forgotten – that shaped Newport Beach in his podcast, “Newport Beach in the Rearview Mirror.” In his most recent podcast, Lobdell shares, “The Freeway That Almost Destroyed Newport” Here’s a preview of his latest episode. In 1970, the Newport Beach City Council and California Department of Highways signed an agreement to build a coastal freeway – 12 lanes wide in places – that would have run through the heart of Newport and include five-level interchanges at Newport Boulevard and West Coast Highway and MacArthur Boulevard and East Coast Highway. To this day, the Coastal Freeway is the biggest “what-if” moment in Newport Beach history. If built, the freeway would have bifurcated the town, separating the harbor and beaches from the rest of the town. It would have brought an estimated 187,000 cars through the city each day. In short, the freeway would have destroyed Newport Beach, as we know it, today.

- Ħ＄ Pacific Coast Highway improvements coming to Huntington Beach (Los Angeles Times/Daily Pilot). Huntington Beach draws about 11 million visitors each year. It only seems like they’re all at Pacific Coast Highway and Main Street at any given moment. Caltrans is planning upcoming improvements on PCH in Surf City, one of several projects approved in Orange County after the California Transportation Commission allocated $700 million in May to repair and improve transportation infrastructure throughout the state. More than a third of the funding comes from Senate Bill 1, the Road Repair and Accountability Act of 2017.
- Ħ Pacific Coast Highway Corridor Study Executive Summary (OCTA). Pacific Coast Highway (PCH) is one of Orange County’s most iconic highways. Directly adjacent to the Pacific Ocean, it traverses beautiful downtowns, open space, as well as, urban centers. PCH is also the corridor that links Orange County’s six coastal cities—Seal Beach, Huntington Beach, Newport Beach, Laguna Beach, Dana Point, and San Clemente. Corridor residents and visitors frequently use multiple modes (vehicles, transit, walking, and bicycling) to travel to and from their activities in and around the corridor. Non-motorized modes such as walking and bicycling serve greater numbers of travelers in this corridor than in most other areas of Orange County. However, all of these diverse travel interactions occurring in an extremely tight right-of-way (ROW), put daily strain on this aging 37-mile long corridor. As a result, the six Orange County coastal cities, requested that the Orange County Transportation Authority (OCTA) and the California Department of Transportation (Caltrans) conduct a PCH Corridor Study extending from the Los Angeles County line (in Seal Beach) to Avenida Pico

- Ħ Rancho Malibu 1931 Marblehead Land Co. map – RMb-50.1 (Malibu Adamson House Foundation). 1931/1924 map of Rancho Malibu, commissioned by the Marblehead Land Co (MBL), a Rindge land holding company formed by May Rindge in 1921, mostly to oversee the numerous and complex land holdings created by Frederick Rindge before his death. The original reason for commissioning this map in 1924 is unclear, but was probably simply for documentation of the Rindge Malibu land holdings. It shows the original, short-lived 1923 County dirt road, the first road to open the Rancho to the public, and the State paved highway (Roosevelt Highway), completed between 1926-1929. It aso shows the pathway of the Rindge railway under the name Hueneme, Malibu and Southern Rwy. Finally, it shows the homesteader land grants surrounding the Rancho. This very valuable map shows the Rancho as it was transitioning from a private ranch to the City of Malibu of today. The map segments shown are overlapping segments proceeding from the western (Yerba Buena Canyon) to the eastern (Las Flores Canyon) boundaries of the Rancho.

The wind was blowing through Malibu’s Decker Canyon on the day Millie Decker stepped out onto her back porch and heard the distant clatter of helicopters. Moments later, several wide-bellied prop planes roared overhead. Millie could not yet smell the smoke or see the flames, because the wind was at her back, but she knew that a fire was coming, and she was determined to fight it. She moved quickly across her property, checking the shovels and gunnysacks and barrels of water with which she would save her ranch, just as her extended family has been doing it since the 1880s. An article on Millie Decker, the last remaining Decker for whom Decker Canyon was named. Marion Decker was the landowner just next to the Malibu Rancho.
- Ħ The Lost U.S. Highways of Southern California History (KCET). US-101 still traces the spine of Spanish California. US-395 continues to parallel the eastern escarpment of the Sierra Nevada. And US-66 charts a direct course to a gauzy, nostalgic past. But these are mere vestiges of our first interstate highway system, one that linked Southern California to the nation with concrete pavement and black-and-white shields. Soon after a joint board of state highway officials adopted the 50,100-mile United States Numbered Highway System in 1926, you could have cranked up your Model T on the Lake Michigan shore, followed signs for US-66, and in 2,451 miles your tires would be kicking up Santa Monica sand. Or, starting at the Peace Arch that straddles the U.S.-Canada border, you might have followed signs for US-99, and within a couple days you’d be cruising past the downtown department stores and movie palaces on Broadway.
- Ħ Alameda Corridor Selects Contractor To Design Pacific Coast Highway Grade Separation Project (Alameda Corridor Transportation Authority). Moving quickly to relieve traffic congestion at a busy intersection, the public agency building the Alameda Corridor rail cargo expressway selected a firm Thursday to design the Pacific Coast Highway (PCH) Grade Separation. One month after agreeing to take on the project, the Governing Board of the Alameda Corridor Transportation Authority (ACTA) authorized staff to enter into a contract with the engineering firm of HDR, Inc. The firm was one of six to respond to ACTA’s request for a statement of qualifications. Two firms were selected to submit formal proposals and be interviewed by a panel of officials from ACTA, the Port of Los Angeles and the California Department of Transportation (Caltrans). The panel unanimously recommended HDR, and the Governing Board agreed, authorizing staff to negotiate a contract. ACTA officials said their goal is to have the agreement executed and a notice to proceed issued in September. ACTA will immediately begin the process of selecting a construction management firm. An accelerated schedule calls for the project to be completed in 18-24 months, with construction commencing in fall 2002.
- Monte Rio undergoes reconstruction (Sonoma County Gazette). Summer is going by so fast with kids already back in school and Labor Day here. It’s been an active summer in the River with many tourists and fun events. Fall is a great time to get camping reservations, without the campgrounds being packed. Hopefully the fire and smoke season doesn’t kick in, but with the hot weather in August, we can only hope for the best. Good government requires investing in infrastructure. It should be evident to all that a lack of investing in infrastructure has proven to be a downfall for Monte Rio. From our roads to our bridges and even to our gateway Welcome to Monte Rio sign, there is a lot of work ahead of us.
- SR 37 Will Be Raised By 30 Ft. to Combat Future Floods (Construction Equipment Guide). California’s efforts to ensure the long-term resiliency of State Route 37 (SR 37) and San Pablo Bay received a significant boost with the infusion of $155 million in federal funding. The California Transportation Commission formally allocated the funds to elevate a key section of State Route 37 to guard against future flooding on a vital regional corridor that connects Marin, Sonoma, Napa and Solano counties and enhance habitat connectivity for San Pablo Bay. The $180 million project will raise the roadway by 30 ft. over Novato Creek by 2029, well above the projected year 2130 sea-level rise.

- ＄ This L.A. freeway is the butt of many jokes. Can it have new life as parks and housing? – Los Angeles Times (Source). The Marina Freeway has long been a peculiarity on the map of Southern California. Envisioned initially as a major route from the Pacific Ocean to northern Orange County, it stands as a testament to the fading era of freeways. Caltrans built a three-mile stretch from the 405 Freeway to the edge of Marina del Rey. But community opposition in the 1960s scuttled the full freeway. Over the years, it went by many names: the Slauson Freeway, the Richard M. Nixon Freeway and, as Johnny Carson once mocked it, the Slauson Cutoff.
- Improvements planned for 91 Freeway in Long Beach (Long Beach Post News).

The Metro board’s Construction Committee this week recommended spending $65.1 million to hire Arcadis U.S. to manage construction of the projects. The full board is expected to vote on the contract on Sept. 28. Funding will come from sales tax revenue from the county’s Measures R and M, according to a staff report. Construction will be paid for with Measure R and state grant dollars.
- Ħ Coast Highway Corridor Management Plan 2004 (Caltrans). The Big Sur Coast Highway Management Plan is the result of collaboration that was made possible through grant funds from the Federal Highway Administration with support from Congressman Sam Farr and the management of the California Department of Transportation. At the outset, Deputy Director for Planning Allan Hendrix (now retired) provided an early vision and resources to begin the collaboration. Deputy District Director of Planning Jerry Laumer (also retired) and Deputy District Director of Maintenance and Operations Steve Price were both instrumental in setting the stage for the work to proceed in District 5.

- Caltrans Explains Why VMT – Vehicle Miles Traveled – Is Such a Concern (Streetsblog California). Check out this cute video from the Caltrans S.B. 743 team, otherwise known as the VMT Reduction Branch. S.B. 743 was that bill passed ten years ago that said to planners: stop pretending that traffic congestion by itself is an environmental problem, and find a different way to measure the real environmental impacts from traffic. The agreed-upon replacement measure was “vehicle miles traveled,” or VMT, a more intuitive way to think about how traffic from development affects the existing environment. Unlike the previous (still extant) measure, which said congestion was the problem, VMT measures whether a project would cause people to drive more.

- Ħ A History of Big Sur Landslides and Highway 1 Closures (KQED). A long the Big Sur coast, residents coexist with certain facts of life: a landscape of unparalleled beauty, tourist traffic, spotty cellphone and internet service — and slides that will shut down Highway 1. “The only question we ever have is where it’s going to close, when and for how long,” says Kathleen Woods Novoa — known as Big Sur Kate to readers of her indispensably newsy blog. “We never question that it’s going to close somewhere every single winter. And it does, just about.” Caltrans records bear that out. A 2001 Caltrans report — “A History of Road Closures Along Highway 1, Big Sur” — has gotten a lot of attention in the last few weeks as one landslide after another has turned Big Sur into an isolated, lonely island. The linked Caltrans report is no longer on the Caltrans website, but I’ve obtained a copy and it will be added to my Caltrans resource page in the next round of updates.

- Western Terminus of US 66 (Southern California Regional Rocks and Roads). The west end of US 66, at least in popular culture, has always been at the Pacific Ocean, or at least close to it. Santa Monica Pier, at times, touts itself as the western end. The intersection of Ocean Blvd and Santa Monica Blvd also does the same. While both are scenic and somewhat obvious ends, they simply are not correct.
- Old State 136 near Keeler, CA (Southern California Regional Rocks and Roads). The Owens Valley in Inyo County, California is home to many fascinating highway relics. One road in particular toward the southern end of the Owens Valley southeast of Lone Pine, State Highway 136, had a very unique and rare feature – old railroad grade crossing markings. Until 1964, it was known as State Highway 190 and was realigned quite a bit between the Owens River and Keeler in the late 1940’s and early 1950’s as travel to Death Valley became more popular. Most of the old alignments are still traversable today, complete with original paving. The longest intact section is known as Dolomite Loop Road and runs between the Owens River bridge to just north of Swansea.

- Caltrans details plans for elevated Highway 37 causeway near Novato (Marin I-J). The first phase of a massive plan to elevate Highway 37 to prevent regular inundation from sea-level rise is set to begin with an estimated $1.6 billion project in Marin. Caltrans officials held a presentation recently on the agency’s plan to rebuild a 2.5-mile section of the 21-mile North Bay commuter route as an elevated causeway from the Highway 101 interchange in Novato to the Atherton Avenue exit. The project would be the first in the agency’s plan to elevate the entire highway onto a causeway before the road connecting Marin and Solano counties becomes regularly inundated by rising sea levels, which Caltrans projects will begin in 2040. At a public hearing on the proposal in Novato this month, Caltrans project manager Javier Mendivil said the project is needed “to incorporate resiliency on the corridor to the effect of sea level rise to 2130 and flooding from stormwater.”
