Routing Routing

Rte 91 / U.S. 91From Vermont Avenue at the eastern city limits of Gardena to Route 215 in Riverside via Santa Ana Canyon.

The relinquished former portions of Route 91 in the Cities of Gardena, Torrance, Lawndale, Redondo Beach, Manhattan Beach, and Hermosa Beach are not a state highway and are not eligible for adoption [as a state highway].

Post 1964 Signage History Post 1964 Signage History

In 1963, this route was defined as "Route 1 near Hermosa Beach to Route 395 via Santa Ana Canyon."

In 1969, Chapter 294 changed "Route 395" to "Route 15" (present-day I-215).

In 1977, Chapter 919 changed "Route 15" to "Route 194".

In 1982, Chapter 681 changed "Route 194" to "Route 215".

In 1994, Chapter 1220 clarified the terminus as "Route 215 in Riverside via Santa Ana Canyon."

In 1997, Assembly Bill 1561, Chapter 945 introduced a discontinuity when a portion of the route was turned over to the city of Gardena. Additionally, a provision has been added to the law to allow a portion of Route 91 to be relinquished to the city of Torrance. This made the definition:

In 1999, the state was permitted to relinquish the portion of Route 91 between Route 107 and Route 1 to the Cities of Hermosa Beach, Lawndale, Manhattan Beach, and Redondo Beach if the cities agree to accept it and the California Highway Commission approves (AB 1650, Ch 724, 10/10/99). This relinquishment was started in 1999:

In 2003, the legislative definition was changed once again to make the route continuous from the eastern limits of Gardena. (Assembly Bill 1717, Chapter 525, 9/25/2003).

In 2018, the state legislature passed a bill related to the HOV lanes on Route 91. Specifically, the bill requires the Caltrans to report to the transportation policy committees of the Legislature, on or before January 1, 2020, on the feasibility and appropriateness of limiting the use of high-occupancy vehicle lanes to high-occupancy vehicles and eligible vehicles, as defined, only during the hours of heavy commuter traffic on both Route 91 between I-15 and I-215 in the County of Riverside, and Route 60 in the County of Riverside.

Pre 1964 Signage History Pre 1964 Signage History

US Highway Shield Route 91 was originally US 91. As this 1926 map shows, it looks like US 91 was originally planned to follow what is now US 95 into Las Vegas (and thus, some sections correspond to the 1934 Route 195). The 1928 definition of the signed route ran from the Nevada-California state line S of Jean NV via Baker to Daggett (an exploration of why the original southern terminus of US 91 was in Daggett may be found in the Gribblenation Blog on the subject). This routing followed the current I-15 alignment south from the Nevada state line, diverging from the current I-15 alignment at the Ghost Town Road exit, headed south to Daggett via Yermo-Daggett Road (and ending at US 66 there). In 1931, US 91 was rerouted away from Daggett to follow Yermo Road and the I-15 alignment, then along old US 466 (now Old Highway 58) west to First Avenue south into Barstow (to end at US 66/Main Street). In 1947, US 91 was extended south to Long Beach via US 66/US 395 and Route 18.

US 91 rarely ran as just US 91:

  1. US 91 originally started in Long Beach at the corner of Pacific Coast Highway and Atlantic Blvd (this was the terminus of US 6, and the junction of US 6, Route 15, and US 91). When the Long Beach Freeway was constructed the terminus was move W two blocks to the freeway junction.
  2. US 91 then ran E along Pacific Coast Highway (US 101A) to Lakewood Blvd (Route 19). This was part of LRN 60, defined in 1919.
  3. US 91 then ran N along Lakewood Blvd (cosigned with Route 19) to Carson St, which turned into Lincoln Avenue. This segment was part of LRN 168, defined in 1933.
  4. Until 1953, US 91 then ran E along Lincoln Avenue, cosigned with the 1934-defined Route 18 to Route 55 (LRN 43 / Santa Ana Canyon). US 91 would run cosigned with Route 18 (LRN 43) into San Bernardino; although by the 1964 renumbering, Route 18 had been trucated to start in San Bernardino). This segment was LRN 178, defined in 1933. Note: in the 1964 renumbering, former US 91/Route 18 W of US 101 was renumbered as Route 214, which wasn't signed and was eventually deleted.

    In response to the construction of the US 101 freeway, LRN 178 was truncated on its eastern end to Manchester Blvd in 1953, and then to US 101 in 1957. The intent was to route US 91 along the a-building Riverside Freeway (Route 14, LRN 175). Seemingly dependent on the year and the mood of the Dept. of Highways, US 91 would take an appropriate N/S to the closest end of the Riverside Freeway -- be that Manchester/Bypass US 101, Brookhurst St, or State College. This sometimes involved US 91 signage on city streets. But the goal was to get US 91 on US 101 for the jog between Route 14 and Route 18 on Lincoln Ave. The segment along US 101 was part of LRN 174, defined in 1933.

    After the 1953 truncation of LRN 178, W of the US 101/Orangethorpe Junction, US 91 then ran E along Orangethorpe, and later the Riverside Freeway, to Santa Ana Canyon, along Route 14 (present-day Route 91). This was part of LRN 175, defined in 1933. Present-day Route 91 follows pre-1964 Route 14 W from the junction with US 101 (now I-5). This is because the post-1964 Route 91 terminates in Hermosa Beach, not Long Beach like US 91 did.

    From Santa Ana Canyon, the route ran NE cosigned with Route 18 to Riverside. By 1962, the Route 18 signage was dropped and it was signed as just US 91. This was part of LRN 43, defined in 1931. Riverside is the present-day eastern terminus of Route 91.

  5. From Riverside to San Bernardino, the route ran cosigned with US 395 (and Route 18). This was also part of LRN 43, defined in 1917. The US 395 signage appears to have started around 1935. The start of the US 91 co-signage is undetermined.
  6. From San Bernardino, the route continue N to the vicinity of Hesperia cosigned with US 66 and US 395. This was part of LRN 31, defined in 1915.
  7. From the vicinity of Hesperia to Barstow, the route was cosigned with US 66. This was also part of LRN 31, defined in 1915.
  8. From Barstow to the Nevada state line, the route was cosigned with US 466. This was the remainder of LRN 31, defined in 1925.

    Originally, this segment was routed through Daggett. But by 1931, the route ran from N Barstow to Yermo, as evidence in a 1931 Conoco California-Nevada map by H M Gousha (which shows US 91 going from Yermo to north of Barstow on a road section constructed in 1930). In January 1930, California Highways and Public Works noted that the contractor “is making excellent progress with the grading on their contract between Barstow and Yermo. This contract includes the laying of oil-treated plant-mixed surfacing 20 feet wide.”
    (Source: Email from Frank Aros)

However, the current definition of Route 91 consisted of only two of these LRNs: LRN 175 between Hermosa Beach and Santa Ana Canyon, and LRN 43 from Santa Ana Canyon to Riverside.

Rte 91/Rte 605 ImprovementsThe SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures on or near this route:

In January 2018, it was reported that Metro and Caltrans District 7, in collaboration with the Gateway Cities Council of Governments (GCCOG), are proposing to make improvements along westbound Route 91, between the I-605/Route 91 (091 LA R16.935) Interchange and Shoemaker Avenue (091 LA R19.818), and at the I-605 northbound exit to Alondra Boulevard (605 LA R5.834). Proposed improvements in the Westbound SR-91 Improvement Project include adding auxiliary lanes, one new general purpose lane in the westbound direction, a lane at the I-605/Route 91 interchange off-ramp, enhancing freeway entrance and exit ramps, and additional improvements on the arterial streets in the vicinity. Technical studies for the project are still underway as of January 2018.

The 2018 STIP, approved at the CTC March 2018 meeting, appears to allocate $22,000K in Advance Program Development Element funds for PPNO 5388, Rt 91 WB, Shoemaker Ave-Rt 605 IC, for PS&E in FY18-19.

In April 2018, it was reported that Metro was applying for TCRP (Trade Corridor Relief Program) funds in addition to SB1 funds for Route 605 / Route 91 Interchange Improvement project.
(Source: Metro The Source, 4/19/2018)

In March 2019, the CTC approved for future consideration of funding a project is located on Route 91 from Shoemaker Avenue to I-605, and on I-605 from Alondra Boulevard to the I-605/Route 91 Interchange in the cities of Cerritos and Artesia (07-LA-91, PM 16.9/19.8, 07-LA-605, PM 5.0/5.8). The purpose of the project is to reduce congestion and improve freeway operations, safety and local and system interchange operations. The proposed project includes additional freeway mainline capacity leading to westbound Route 91 connector ramp to northbound and southbound I-605, improvements to freeway entrance and exit ramps in the westbound direction of Route 91 and operational improvements for the northbound I-605 at the Alondra Boulevard off-ramp. This project proposes to address the inadequate capacity of the existing two-lane connector for westbound Route 91 to I-605. This project is fully funded and currently programmed in the 2018 State Transportation Improvement Program (STIP) for approximately $187.8 million. Construction is estimated to begin in 2022. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2018 STIP. The CTC also approved an allocation of $26,000,000 for the multi-funded locally-administered Senate Bill 1 (SB 1) Trade Corridors Enhancement Program (TCEP)/State Transportation Improvement Program (STIP) Route 605/Route 91 Interchange Improvement: Gateway Cities Freight Crossroads Project (PPNO 5388), on the State Highway System, in Los Angeles County.

Orange County — County Line to Route 57

In August 2011, the CTC approved $21,457,000 in SHOPP funding in the cities of La Palma, Buena Park, Anaheim and Fullerton, from the Los Angeles County Line to Lakeview Avenue, that will resurface mainline and ramps on 128 lane miles of pavement to improve safety and ride quality. Project will replace damaged slabs, grind pavement, overlay existing asphalt pavement and ramps, and install concrete termini at ramps.

Route 57 Auxiliary Lanes

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 (~ ORA R3.855L to ORA 6.015) and between Route 55 and the Riverside County border (~ ORA R9.193 to ORA R18.869); adding lanes on I-405 between I-605 and Route 55; a new NB lane on Route 57 between Orangewood Avenue and Lambert Road.

In August 2010, the CTC approved for future consideration of funding a project that will construct an additional westbound lane from Route 5 to Route 57 (~ ORA R3.855L to ORA 6.015) in the cities of Anaheim and Fullerton. The project is programmed in the Trade Corridors Improvement Fund and includes local funds. Construction is estimated to begin in Fiscal Year 2012-13. Total estimated project cost is $73,400,000 for capital and support. The scope as described for the preferred alternative is consistent with the project scope set forth in the proposed project baseline agreement.

In September 2012, the CTC approved $34,950,000 in SHOPP funding on Route 91 for the Route 91 Auxiliary Lane Connection. In Fullerton and Anaheim, westbound from Route 57 to I-5. Construct a lane on existing auxiliary lanes through interchanges to form a continuous fourth lane. (TCIF Project 34) (Future Consideration of Funding – Resolution E-10-75, August 2010.) (Contributions from other sources: $13,050,000.) Outcome/Output: Construct 4.6 miles of new lanes. Hours of congestion are decreased approximately 10 percent on the freeway.

In February 2012, the CTC updated the project. The intent of the project is to connect existing auxiliary lanes through interchange from Route 57 to I-5 project will create a fourth mixed-use lane on westbound Route 91 by connecting existing auxiliary lanes through interchanges. The project is currently programmed with $34,950,000 in TCIF funds and $35,750,000 in local measure funds. The project is scheduled for construction in December 2012. The amendment moved the replacement planting scope to a separate project funded with $2,455,000 in local measure funds. It also updated the funding plan for support and capital components funded with local measure funds. Construction is currently scheduled to end in October 2016.

In April 2016, it was reported that a six-mile stretch of westbound Route 91 had opened, providing new general-purpose and auxiliary lanes and widened bridges and ramps. Located between Route 57 and I-5, the improved area includes four miles of new general-purpose lanes in the westbound direction and auxiliary lanes that allow traffic to more smoothly enter and exit the freeway. The improvements were led by OCTA and Caltrans. The $61 million improvement project was paid for with a combination of state Prop. 1B and local funds from Measure M, Orange County’s half-cent sales tax for transportation improvements.

Orange County — Route 57 to Route 55

Tustin Ave Aux Lane

Rte 91/Rte 55In August 2011, the CTC approved for future consideration of funding a project to extend a westbound lane from the northbound Route 55/westbound Route 91 connector (~ ORA R9.216) through the Tustin Avenue interchange (~ ORA 8.4) and reconstruct the westbound auxilliary lane from east of the northbound Route 55/westbound Route 91 connector to the Tustin Avenue off-ramp. Construction is expected to begin in FY 2014-2015.

In June 2016, it was reported that the Route 91 Auxiliary Lane Project was completed, which extended an auxiliary lane at the freeway’s interchange with the northbound Costa Mesa Freeway (Route 55) and added a bypass lane at Tustin Avenue. The cost of this project was approximately $41.9 million.

Orange County — Route 55 to Route 241

Route 91 Express Lanes (~ ORA R9.252 to ~ ORA R16.004)

Toll Road Has parallel (toll) express lanes from Route 55 (~ ORA R9.252) to the junction with Route 241 in Orange County (~ ORA R16.004), opened in 1996. These toll roads are the subject of contention due to a non-compete agreement, which prevents the public transportation agencies from upgrading their highway or adding lanes without compensating the company. This resulted in a payment of $4M in public funds for the rights to ease a bottleneck along a 1,000 yard stretch of freeway just each of Coal Canyon Road. In order to speed improvements on this congested stretch of highway, the OCTA agreed on 4/19/2002 to purchase the 10 miles of toll lanes for $207.5M. Under the agreement, the Orange County Transportation Authority (OCTA) will assume the toll road's $135M debt, and make a one-time payment of $72.5M (which includes the $4M Coal Canyon Road improvement payment). Although touch and go in the state assembly, a bill authorizing this purchase was approved on 9/18/2002. (Assembly Bill 1010, Chapter 688, 9/18/2002). Note that the tolls on these lanes are adjusted quarterly as part of the Orange County Transportation Authority's congestion management pricing policy. It calls for dropping and raising tolls based on traffic demand. Traffic volumes are monitored daily and adjusted quarterly. An example of this adjustment was in January 2010, when the toll for those traveling in the eastbound direction on Wednesdays from 3 p.m. to 4 p.m. saw the toll drop from $5.45 to $4.95, and those travelling on Fridays from 2 p.m. to 3 p.m. saw the toll drop from $4.10 to $3.60.

[Toll Chart]In December 2007, it was announced that in January 2008, the toll on Fridays on the eastbound 91 Express Lanes will rise to $10; this rise comes nine months after the boost to $9.25. It will be in effect from 3 to 4 p.m. This is an example of congestion pricing — additionally, the eastbound toll during the same 3 to 4 p.m. hour will increase from $4.95 to $5.95 on Wednesdays and from $4.95 to $5.70 on Thursdays. As of 2007, Route 91 was one of the most congested highways in Southern California. More than 320,000 vehicles use the freeway each day to commute between Orange and Riverside counties.

In December 2011, the results of a survey regarding use of the toll lanes was released. Typical users of the toll lanes are fully employed, relatively well-off men who pay the fees to avoid long traffic delays when they drive to visit friends and relatives or for recreational outings. Those least likely to pay are students, the unemployed and those earning less than $25,000 a year. Commuters heading to and from work constitute less than half of those who use the toll lanes. Overall, 90 percent of those who use the toll lanes said they "were generally satisfied with their experiences," and they estimated they shave about half an hour from their travel times by paying the tolls. The average monthly toll bill for those surveyed was $57.55. More details can be found in the Voice of OC article.

In December 2016, it was reported that for the first time in its 21-year history, the entire 91 Express Lanes has been repaved. Working together, agencies, project management partners and the construction contractor finished major repaving in only 8 weekends rather than the 10 weekends originally scheduled. The project paved 20 miles, restriped 110 miles, used 113,000 tons of asphalt and ground and replaced 375,000 square yards of pavement. The project was paid for entirely by the 91 Express Lanes Capital Reserve Fund, the 91 Express Lanes pavement project will extend the pavement’s lifespan for decades while continuing to provide a safe, smooth commute. Periodic nighttime closures will be needed to complete the finishing touches. In addition to the pavement work, the project includes replacing six changeable message signs, replacing channelizers, completing electrical work and replacing pavement markers. The entire project is expected to be completed by January 2017.

In January 2020, it was reported that in 2019, the section administered by OCTA recorded 17.5 million trips, a 4.9 percent increase compared to 2018. Gross potential toll revenue reached $51.9 million, up 4.4 percent since 2018. Additionally, in 2019, OCTA installed new transponders and updated in-lane technology to support them, planned and funded a state-of-the-art back office system to streamline processing for the ever-growing customer base, improved safety by doubling the number of California Highway Patrol (CHP) officers, and continued in its mission to expand and improve Route 91 for all those who travel in the region. In 2020, OCTA is rolling out transponders equipped with 6C, an industry-standard tolling technology mandated by the State of California. These new tickets to ride are about the size and shape of an adhesive bandage and stick on windshields. Because these smaller, lighter transponders are less expensive to produce and distribute than traditional versions, OCTA is passing on the savings to customers via simplified account plans.

In 2007, Rep. Gary Miller, R-Diamond Bar, introduced a $390,000,000 bill in Congress to widen Route 91 and take other measures to try to decongest the heavily clogged route. The bill would allocate $221.3 million for an extra lane in both directions, from Route 55 to the Riverside County border (~ ORA R9.294 to ORA 18.313); $65 million for a special interchange in San Diego County making it easier for northbound truckers on I-5 to go east on Route 56 (thus diverting those who head north, take Route 55 and then going east on Route 91); $56 million to construct an interchange connecting the Route 91 Express Lanes and the Route 241 Toll Road; $40.7 million for an eastbound lane from Route 241 to Route 71; and $7.1 million for added lanes for truck weigh stations. The earliest any of the bill's projects could be completed is by 2011. By 2030, daily usage is projected by transportation officials to swell to 450,000.

Route 55 Connector to Weir Canyon (~ ORA R9.252 to ~ ORA R14.46R)

In November 2010, the CTC approved amending the Corridor Mobility Improvement Account (CMIA) Program and the State Transportation Improvement Program (STIP) for the Route 91 Widening — Route 55 connector to Weir Canyon project (PPNO 4598A) in Orange County (~ ORA R9.252 to ~ ORA R14.46R) to advance the construction schedule from Fiscal Year (FY) 2011-12 to FY 2010-11 and to split out $2,498,000 of STIP Regional Improvement Program (RIP) to later landscaping work required for the project.

In June 2009, the CTC approved for future consideration of funding this project, which will add one general purpose lane on eastbound Route 91 between the Route 91/55 connector and east of Weir Canyon Road interchange, and on westbound Route 91 east of Weir Canyon Road interchange and Imperial Highway interchange. This project will also modify the westbound on-ramps at Lakeview Avenue interchange. The project is programmed in the Corridor Mobility Improvement Account and the 2008 State Transportation Improvement Program. The estimated project cost is $96 million, capital and support. Construction is estimated to begin in Fiscal Year 2010-11. The scope, as described for the preferred alternative, is consistent with the project scope set forth in the approved project baseline agreement.

In May 2010, the CTC approved relinquishment of right of way in the county of Orange, to the Orange County Flood Control District, a political entity governed by the Orange County Board of Supervisors, along Route 91 between Weir Canyon Road and Coal Canyon Road, consisting of collateral facilities.

In July 2011, it was reported that groundbreaking was scheduled for the $84 million project that will add one general-purpose lane for six miles in each direction between Route 55 and the Route 241. Crews will widen the bridge for Imperial Highway and the Weir Canyon Road undercrossing in both directions. Traffic estimates for 2011 are that this section of Route 91 carries an average of up to 174,000 vehicles in the eastbound direction with about 160,000 vehicles that travel the westbound portion of that freeway. By 2014, officials expect that traffic volumes will grow to an average of 158,000 to 190,000 daily. Funds for the widening project come from the State Transportation Improvement Program and Proposition 1B — a bond approved by voters in November 2006. About $400,000 in funds are also provided by the renewed version of Measure M that voters approved in 2006.

In August 2015, it was reported that there are indications that some of the Route 91 improvements are working. Caltrans officials said the completion of a widening project on Route 91 between Route 55 and Route 241 helped to reduce the delay experienced by all motorists from 5,169,147 hours a year in 2010 to 3,657,120 in 2011, or 29%. In 2012, preliminary Caltrans figures show the amount of annual delay dropped an additional 12%. The latest available data from early 2014 shows, however, that the amount of time wasted in traffic per year because of congestion is on the rise. In the least, transportation officials say, the improvements have kept up with the growth in traffic, and commute times have not increased.

Route 241 to Route 91 Connectors 12-ORA-91 (PM 14.7/18.9), and 08-RIV-91 (PM 0.0/1.5)

Rte 241 Rte 91 ConnectorsIn November 2016, it was noted that the Transportation Corridor Agencies (TCA), in coordination with Caltrans, is proposing to add a direct connector linking the northbound Route 241 Toll Road to the eastbound Route 91 Express Lanes and the westbound Route 91 Express Lanes to the southbound Route 241 Toll Road. The direct, median-to-median tolled connector would reduce traffic congestion in both directions, enhance safety by reducing weaving across lanes and improve access to toll lanes in Orange and Riverside Counties. The 60-day public comment period for the Draft Supplemental Environmental Impact Report/Environmental Impact Statement closed on January 9, 2017. The Project Development Team is reviewing and evaluating all comments received. Responses to these comments will be included in the Final Environmental Impact Statement/Record of Decision (FEIS/ROD) in approximately December 2017. (Note that as of March 2019, there were still no updates on this project).
(Source: District 12 Project Page)

According to the Draft SEIR, the Proposed Project, located at the junction of Route 241 and Route 91 in the cities of Anaheim, Yorba Linda, and Corona, and the counties of Orange and Riverside, would provide improved access between Route 241 and Route 91, and is proposed to be a tolled facility. The proposed median-to-median connector project encompasses 12-ORA-241 (PM 36.1/39.1), 12-ORA-91 (PM 14.7/18.9), and 08-RIV-91 (PM 0.0/1.5) for a total length of approximately 8.7 miles (mi). The improvements for the connector include 5.9 mi in the cities of Anaheim and Yorba Linda and unincorporated Orange County, from south of Windy Ridge Wildlife Undercrossing on Route 241 to Coal Canyon Undercrossing on Route 91. The remaining 2.8 mi of the Proposed Project include signage improvements (advance signage) in the cities of Anaheim (1.2 mi), Yorba Linda (0.1 mi), and Corona (1.5 mi) and unincorporated Orange and Riverside counties, with exact placement of the signage pending the Final Design process. The Proposed Project is mostly within existing California Department of Transportation (Caltrans) right-of-way, with one partial acquisition required adjacent to eastbound Route 91. Construction access and staging areas would occur within existing Caltrans right-of-way and the partial acquisition adjacent to eastbound Route 91 as noted above. The objectives of the Proposed Project are to implement the buildout of the Eastern Transportation Corridor (ETC), attain compatibility with the Route 91 mainline and 91 Express Lanes configuration, improve operations and traffic flow between the 91 Express Lanes and the Route 241 general purpose connectors, help achieve the Regional Mobility Plan goals of reducing emissions from transportation sources, and enhance the efficiency of the tolled system, thereby reducing congestion on the non-tolled system on Route 91. The Proposed Project is needed to provide a direct connection between Route 241 and the 91 Express Lanes to accommodate the buildout of the ETC as well as existing and future transportation demand. The proposed median-to-median connector is a later phase of the ETC project, previously approved in 1994. It was originally evaluated as a Route 241/Route 91 highoccupancy vehicle (HOV) direct connector in the 1991 ETC Draft Environmental Impact Report/Environmental Impact Statement (Draft EIR/EIS), 1992 ETC Final EIR, and the 1994 ETC Final EIS (all of which studied a broader Project Area with improvements on Route 133, Route 241, and Route 261. There was only one build alternative and the no-build alternative.
(Source: Draft SEIR for Rte 241/Rte 91 Connectors, Project Alternatives Chapter)

The Build Alternative would construct a two-lane express lane median-to-median connector between Route 241 and Route 91, which would connect lanes from the median of northbound Route 241 to the existing eastbound median 91 Express Lanes and the reverse movement from the westbound median 91 Express Lanes to the median of southbound Route 241. The connector would be tolled. The Build Alternative would merge into the existing Orange County Transportation Authority (OCTA) 91 Express Lanes at Coal Canyon Undercrossing. The Riverside County Transportation Commission’s (RCTC) Route 91 Corridor Improvement Project (CIP) will extend the express lanes on Route 91 east to I-15. The Build Alternative is compatible with the approved Route 91 CIP for both the initial and ultimate configurations, including the number and widths of the express lanes, express auxiliary lanes, and general purpose lanes.

In December 2017, it was reported that OCTA leaders have pushed for a delay on any plans for a $180 million ramp linking the Route 241 toll road and Route 91 Freeway Express Lanes (~ ORA R16.184) over fears the project could increase congestion on both the freeway and the tollway that runs along the middle of it. The 10-3 vote by the Orange County Transportation Authority’s board requests that the Transportation Corridor Agencies – the public agency that runs the Route 241 toll road and is the driving force behind the proposed connector – slow down on plans for an elaborate ramp connecting the paid traffic lanes. Instead, the OCTA board directed its staffers to work with the Riverside County Transportation Commission to come up with big-picture proposals on how to improve the chronically congested traffic lanes on Route 91. The vote follows a recommendation earlier this month by the OCTA’s Executive Committee. It is unclear if the project could proceed without the backing of the OCTA, which owns the 91 Express Lanes. Rush-hour commuters coming from south and central Orange County going to Riverside County who are willing to pay tolls to avoid as much congestion as possible must choose: Take Route 241 and endure the Route 91 freeway, because drivers can’t enter the Route 91 Express Lanes at that point. Or endure traffic before reaching the Route 91 Express Lanes. It takes a long leg in the middle to take both. The ramp would connect the tollways in both directions, although public debate has focused on the eastbound direction. The Transportation Corridor Agencies touts the Route 241/Express Lanes connector as key to decreasing congestion, creating more efficient toll lanes and improving safety for drivers who would no longer have to weave over multiple lanes of traffic to move between Route 241 and 91 Express Lanes at the county border. That is the first place motorists coming from Orange County can exit the Express Lanes; they can enter it there, too. OCTA’s staffers, however, disagree. They say the connector would lure more motorists to the overall corridor, and create more weaving at the Orange County/Riverside County line. Orange County Supervisor Shawn Nelson questioned why if Caltrans thought the current freeway setup was so dangerous its officials didn’t do something about it when Route 241 was first built.

In December 2017, it was reported that Orange County Transportation Authority staffers fearful of increased congestion on the Route 91 freeway and the adjacent 91 Express Lanes want Route 241 toll road leaders to pump the brakes on plans for a $180 million ramp linking Route 241 and the Express Lanes. Further, an executive committee, comprised of seven OCTA board members, backed that opposition, preferring that the Transportation Corridor Agencies, which manages Route 241, to defer any work on the planned connector. Leaders of the Riverside County Transportation Commission have raised similar concerns about the elaborate ramp increasing traffic and congestion. The project would create a clear shot from Route 241, which runs between south and north Orange County along its eastern side, to the 91 Express Lanes that roll along the middle of Route 91 into Riverside County, bypassing typical freeway traffic the entire route for those willing to pay tolls. Caltrans, which serves as owner and operator of state freeways, has approved the draft environmental plan for the connector, said Caltrans spokeswoman Lindsey Hart. The agency is still analyzing traffic data and public comments about the connector to “determine the potential traffic benefits of the project,” she added. The TCA was hoping to complete the final design of the connector in early 2018. If approved, construction could begin in early 2019 and take about two years to complete.

In April 2019, it was noted that concerns about the Route 241/Route 91 transition have prompted Transportation Corridor Agencies (TCA) officials to add increased signage, and double white lines in an attempt to deter drivers from cutting into the NB Route 241 to EB Route 91 transition at the last minute. But even an increased number of law enforcement officers issuing citations doesn't seem to be deterring drivers from illegally cutting across the double white lines. TCA is also considering both short-term and long-term fixes to this problem. One option includes installing pylons, also called delineators or channelizers, between the eastbound and westbound transition lanes. A feasibility study is currently underway, but TCA would not give a time frame on the project. Ultimately, the decision on whether to install channelizers up to Caltrans. Caltrans is in discussions with TCA about the potential use of delineators, centering around various items including who will maintain them, what benefit they will add, and if they are safe to place at this location. They want to ensure that the delineators are set up in a way that those who are maintaining them can do so safely, as well as understanding the impacts that delineators can have on weaving (merging) vehicles, the study of current traffic patterns, and what types of traffic management actions will be needed to maintain the delineators. As noted above, the long-term fix is the dedicated connector. Construction could begin in 2021, with completion in 2023.

In May 2019, it was reported that Caltrans received a 23-page letter from Riverside County transportation officials about all the things they think are wrong with plans for bridges that would let toll road drivers bypass lanes of traffic to get between the Route 241 and Route 91 freeways. The state agency and toll road officials say they’re taking seriously those concerns – also shared by Orange County’s transit agency – as they decide whether to start designing the $180 million ramps, but “as of now we are moving forward with the project,” Caltrans spokesman David Matza said. Riverside and Orange county officials fear solving backups on the Route 241 toll road will make things worse on the Route 91 unless the fixes they’re planning on the Riverside Freeway are done first. They also question traffic study data they say is too old and inconsistent. The four agencies appear set for a turf battle: on one side are Caltrans, which owns the state highway system, and the Transportation Corridor Agencies, which manage Orange County’s toll roads; on the other, the Riverside and Orange county transit agencies, which have typically taken the lead on long-term planning and funding for new local freeway projects. Everyone agrees building a direct path between the Route 241 toll road and Route 91 express lanes ultimately would help clear backups and improve safety. Toll road officials want to solve congestion near the Route 241 Windy Ridge toll plaza, where northbound cars are funneled onto the eastbound Route 91. Using the existing medians, the proposed bridges would provide a direct route into the 91 express lanes; in the other direction, there’s currently no way to get from the westbound Route 91 express lanes to southbound Route 241. Orange and Riverside county transit officials want time to do three other projects intended to loosen choke points between I-15 and the Orange County line: building another westbound lane on Route 91 from Green River Road to Route 241; adding ramps to move cars from the Route 91 express lanes to the I-15; and replacing a hairpin-turn offramp from Route 91 east to Route 71 north with a flyover ramp that wouldn’t slow traffic as much. If TCA’s new ramps are built and opened first, they could dump hundreds more cars into the Route 91 express lanes at peak drive times, forcing some drivers into already crowded general purpose lanes, Orange County Transportation Authority spokesman Joel Zlotnik said. (Drivers would pay an additional toll to use the new bridges.) The timeline for at least one of the projects on Route 91 remains uncertain. The added westbound lane and I-15 connector project could be done in 2022, but officials don’t yet have funding for construction of the Route 71 interchange. Caltrans is nearly done with the environmental analysis, after which design can begin. A two-year construction schedule could wrap up in 2023.

In November 2019, it was reported that OCTA approved an agreement with the Riverside County Transportation Commission, Transportation Corridor Agencies and Caltrans that lays the groundwork for the construction of a tolled connector between the Route 241 Toll Road and the Route 91 Express Lanes. The agreement is a result of several months of discussions and sets the stage for traffic relief, while ensuring the project smoothly integrates with others planned in Orange and Riverside counties, including the Route 91 Express Lanes/I-15 Connector and the Route 91 Corridor Operations Project. The proposed project would connect the Route 241 Toll Road directly with the Route 91 Express Lanes, about 2 miles west of the Orange County border with Riverside County. Construction of the connector is anticipated to begin in 2023.

In May 2020, the CTC approved for future consideration of funding a project for which a Final Supplemental Environmental Impact Report (FSEIR) has been completed: Route 241 and Route 91 in Orange and Riverside Counties. Construct a tolled facility between Route 241 and Route 91 in Orange and Riverside Counties. (EA 0K9700) The project is located in the cities of Anaheim, Yorba Linda, and Corona in Orange and Riverside counties. The project proposes to improve access and reduce congestion at the Route 241/Route 91 interchange by providing a direct connector between Route 241 Toll Road and the
Route 91 Express Lanes. The estimated project cost is $182,298,000. Construction is estimated to begin Fiscal Year 2022-2023. The Department, the Orange County Transportation Authority, the Riverside County Transportation Commission and the Toll Roads Corridor Agency support the project.
(Source: May 2020 CTC Agenda, Agenda Item 2.2c.(8))

According to the FSEIR, the purpose of the Proposed Project is to implement the build out of the Eastern Transportation Corridor (ETC), for which the Final Environmental Impact Report/Environmental Impact Statement was approved in 1994. The overall objective of the ETC project was to accommodate traffic growth associated with planned and approved development in Orange County. In addition to the originally intended objectives of the ETC, changed circumstances at the Route 241/Route 91 interchange have led to the following objectives for the Proposed Project: implement the built out of the ETC, as approved in 1994; attain compatibility with the Route 91 mainline and Route 91 Express Lanes; improve traffic flow and operations by reducing weaving across multiple general purpose lanes between the Route 91 Express Lanes and the Route 241 general lane connectors; and enhance the efficiency of the tolled system, thereby reducing congestion on the non-tolled system on Route 91. The need for the Proposed Project is to address roadway deficiencies including: peak-hour demand exceeding capacity between the Route 241 and Route 91 connectors, lack of connectivity between tolled/managed facilities, and weaving between general purpose connectors and median lanes reducing traffic flow. Caltrans, in cooperation with the Foothill/Eastern Transportation Corridor Agency (F/ETCA), proposes to construct a tolled direct connector between Route 241 and the Route 91 Express Lanes. Currently, there is no direct connection between the Route 241 toll road and the 91 Express Lanes.

Route 241 (Orange County) to Route 71 (Riverside County)

Chino Hills Widening (~ ORA R16.184 to RIV R2.015)

In December 2005, the OCTA and the RCTC approved the addition of an extra eastbound lane, from the Foothill-Eastern tollway (Route 241) in Anaheim to the Corona Expressway (Route 71). Plans call for completion of that lane in two to three years. They also approved the planning phases of a widening project for one or two lanes in both directions between I-15 in Riverside County and Route 55 in Orange County. Board members also asked for more analysis on the possibility of adding four to six lanes elevated over the median or alongside Route 91 from I-15 to the Route 261. The agency eliminated from consideration plans to widen Route 55, into which Route 91 feeds, and to widen Ortega Highway (Route 74) in South County. Some of these items were submitted for funding from the 2007 Corridor Mobility Improvement Account (CMIA) allocations. The projects approved for funding on this route were the EB auxiliary lane, Route 241 to Route 71 ($71.4 million funded out of $73.8 million requested) and the addition of lanes from Route 55 to Gypsum Canyon ($22 million funded out of $48 milllion requested). However, there were two requests that were not recommended for funding: a WB auxiliary lane from Route 55 to Tustin ($47.5 million), and converting the WB auxiliary lanes to through lanes from Route 57 to I-5 ($36 million).

In January 2009, the CTC approved for future consideration of funding roadway improvements including widening of existing lanes and constructing an additional lane on Route 91 between Route 241 near Yorba Linda and Route 71 near Corona. Specifically, the project will construct roadway improvements to a 6.9 mile long section of Route 91 in Riverside and Orange Counties. The improvements will include widening of existing lanes and shoulders and the construction of an additional lane in both directions between Route 241 and Route 71. The project is programmed with corridor mobility improvement account funds, traffic congestion relief funds, local funds, federal demonstration funds, and Regional Measure 2 funds. The total estimated project cost is $81,400,000. The construction is estimated to begin in Fiscal Year 2009-10. The scope, as described for the preferred alternative, is consistent with the project scope set forth in the approved project baseline agreement. The rough routing is as follows:

[241-71]In November 2009, construction began on the $59.5-million project. The roughly 6-mile-long project will run from Route 241 to Route 71, and will add one lane to the four existing eastbound lanes, excluding two express lanes. In January 2010, the CTC adjusted funding so that demonstration construction could start sooner using design-build. The lane was opened to traffic in December 2010.

In June 2012, information was provided on the estimated pricing for the Corona HOT lanes. The peak rush-hour toll for the eastbound Corona stretch would be $5.45; through the Santa Ana Canyon in Orange County, the highest price now is $9.75. The full, 18-mile stretch could top $15 for a one-way trip on a Friday afternoon. Work on the lanes is scheduled to begin in 2013. A firm will be chosen in early 2013 to finalize designs and build the new lanes and other improvements. Once the lanes are complete, transitioning between the toll lanes in Riverside County and Orange County will appear seamless for drivers. The same in-car transponders will track the tolls, and all the charges will be on the same monthly bill. Drivers will be able to choose whether to take the toll lanes in each county. For example, a driver could use them to bypass slow traffic in Riverside County but hop into the general-use lanes in Orange County. Similar to the Orange County setup, electronic message signs will advertise the current price at toll-lane entry points. Unlike Orange County, which raises prices only when traffic flow reaches a threshold of 3,128 cars per hour, Riverside County officials approved a tiered approach that could result in more fluctuations in the hourly price, depending on how busy the freeway is at those times.

In March 2013, the CTC approved $39,173,000 in funding for construct of one mixed flow lane in each direction from Route 241 to Pierce Street (~ RIV 10.853), collector distributor system from Lincoln Avenue to I-15, one new HOT lane/convert existing HOV lane from County Line (Design-Build Project).

In December 2013, Riverside County broke ground on a long-anticipated widening project meant to smooth away a bottleneck that snags traffic at its border with Orange County. The project will widen each side of the freeway from four regular lanes to five and replace the single carpool lanes with dual pay-to-ride express lanes. Construction is scheduled to get underway in earnest by January and last until 2017.

The 2009 Economic Simulus funds were expected to speed up the construction of Route 91 between Route 241 and Route 71. OCTA staff members recommended that about $71 million of the expected stimulus money go toward Route 91 freeway project. An additional $4 million will come from toll revenue and state funding, and $5 million will come from the Riverside County Transportation Commission. Nearly 2,000 jobs would be created by Route 91 widening project. Construction is scheduled to begin in July 2009.

At its meeting on June 11, 2009, the CTC approved the request from the OCTA to delete the Route 91 Eastbound Lane — Route 241 to Route 71 Interchange project (PPNO 4678) in Orange County from the CMIA program. OCTA replaced $71,440,000 of CMIA funds with regional funds from the American Recovery and Reinvestment Act of 2009 (Recovery Act).

In February 2018, it was reported that RCTC officials still feel that fixes are needed in the Route 91 corridor. An additional westbound freeway lane, from Route 71 Freeway to Route 241, was one solution presented in mid-February 2018 to the Riverside County Transportation Commission. Corona Mayor Karen Spiegel and a few other commission members cited that option as one worth exploring to deal with back-ups on Route 91 and nearby city roads that have left some commuters frustrated. Since the toll lanes opened in March 2017, they’ve been used by 1.2 million vehicles — about 40 percent more than the agency projected — a report to the commission states. That’s 37,893 vehicles on an average day. That figure has resulted in $22.1 million in toll revenue — about $15.5 million more than the agency anticipated. The project has reduced congestion during many times of the day on the heavily-traveled corridor. However, there are some “hot spots” at which motorists continue to face congestion, including the entrance to the toll lanes on westbound Route 91, past McKinley Street, and the northbound I-15 Freeway connector to westbound Route 91 entering the toll lanes. One of the worst is westbound Route 91 from Route 71 going past Green River Road and toward the Orange County line. During the morning commute, 1,800 to 2,000 vehicles an hour are entering the westbound Route 91 from Route 71 and Green River. As a result, Green River — which connects to Route 15 through the Foothill Parkway — has seen vehicles backing up for a mile or two on weekday mornings, residents say. The additional lane — which would be added by converting the existing right-hand shoulder pavement — is one of six options for the Green River corridor. Others included adding the lane for a shorter distance, moving the toll lane entrance and exits further east, converting the toll lane exit and entrance into a continuous weaving lane and turning off the metering ramp at the Green River entrance. For northbound I-15, the two proposed solutions were extending the toll lanes further south and adding a second entrance to the toll lanes.

In May 2018, it was reported that the Riverside County Transportation Commission approved in a near-unanimous vote environmental studies and design work for adding a general-purpose westbound lane on Route 91, stretching from Green River Road (~ RIV R1.944) to Route 241 in Orange County. The panel intends to reconvene in the fall to decide whether to move forward with construction of the new lane, expected to cost $30 million to $50 million and take two and a half years to build.
(Source: Press Enterprise, 5/9/2018)

In December 2018, it was reported that the Riverside County Transportation Commission approved adding a new westbound lane on Route 91 stretching from Green River Road in Corona to the Route 241 toll road in Orange County. The $42 million project will increase the number of general-purpose lanes to six on the 2-mile-long westbound section of the freeway. Environmental studies are underway. The panel, governed by representatives from Riverside County and each county city, decided to press forward to complete those studies, design the new lane and build it. Construction could start in summer 2020 and be completed by fall 2021, according to a report given at the meeting. Still to be determined is the source of funding for the construction component — estimated at $36.2 million. The lane will be built at a major choke point on the crucial artery that connects Riverside County commuters with jobs in Orange and Los Angeles counties. According to the commission, 312,000 vehicles travel Route 91 daily at the Riverside-Orange county line. The lane is part of a package of improvements the panel endorsed in May with the goal of improving traffic conditions through Corona. The commission also lengthened by 1 mile a toll lane on northbound I-15 near Route 91 and repainted lines to create a continuous express-lane entrance-exit lane at the county line.

In April 2019, it was reported that the City of Corona hoped to relieve pressure on two city streets that routinely clog in the morning rush hour by making other routes to Route 91 more attractive to regional commuters. The problem is that commuters routinely cut through the city of 165,000 and transform Green River Road and Serfas Club Drive into gridlock. The city wants those commuters to instead consider getting back on the freeway at Main Street or Lincoln Avenue. Corona is working to synchronize traffic signals on Main and Lincoln, and travel speeds have improved on those north-south arteries. The new strategies are being touted in the wake of widespread frustration in Corona about the traffic nightmare that persists despite the 2017 completion of a $1.4 billion makeover of Route 91 between I-15 and the Riverside-Orange county line.
The city also is rolling out other strategies to get cars moving on Green River and Serfas Club, including installation of a new traffic signal along Green River at Montana Ranch Road and plans to add another at the Green River intersection with Tanglewood Drive. On Serfas Club  Drive, the city plans to add a second turn lane in each direction to let commuters merge onto westbound Route 91 faster in the morning. The city also wants the option of turning off ramp meters at the Green River entrance to westbound Route 91 in the wake of a major accident that ties up the freeway and side streets when the freeway recovers quicker and the local streets are falling behind. But Caltrans is not likely to agree to that.

Green River Interchange (~ RIV R1.944)

[TCRP 64]There are currently plans (TCRP #64) to improve the Green River Interchange to NB Route 71, including adding an auxiliary lane and connector ramp. (June 2002 CTC Agenda Item 2.1c.(1)). In August 2007, the CTC approved two actions regarding this project, specifically with Project #64.1 and #64.2. TCRP #64.1 would improve the Green River Interchange and add an auxiliary lane and connector ramp east of the Green River Interchange to northbound Route 71 in Riverside County. Project #64.2 would improve the Green River Interchange and add an auxiliary lane and connector ramp east of the Green River Interchange to northbound Route 71 in Riverside County. The actions that were approved were to transfer $590,000 in TCRP funding from TCRP #64.1 to TCRP #64.2 for Plans, Specifications, and Engineering (PS&E), to program $4,410,000 in new TCRP funds for PS&E on #64.2, and to update schedules. The overall project goal is to relieve congestion and improve local traffic circulation on Route 91 in the area of Green River Road and Route 71. TCRP Project #64.1 relieves congestion on Route 91 in the area of Green River Road and Route 71 and improves local traffic circulation on Green River Road in the vicinity of Route 91 by replacing the current 3-lane Green River Road overcrossing with a 6-lane overcrossing, modification of ramps, and local street improvements at the interchange. Project 64.1 was completed in 2007 with funds remaining in the account due to various transfers. TCRP Project #64.2 relieves congestion on Route 91 in the eastbound direction by adding a lane in the vicinity of the Green River Interchange on eastbound Route 91 between Route 241 and Route 71, near the Riverside/Orange County line, extending to the Route 71/Route 91 interchange near the city of Corona in Riverside County. This project should complete in FY11/12.

In October 2011, the CTC approved for future consideration of funding a project to construct a direct flyover connector from eastbound Route 91 to northbound Route 71 and reconfigure the eastbound Route 91 ramp between Green River Road and the Route 91/Route 71 interchange. The project is not fully funded. The project is programmed in the 2010 State Transportation Improvement Program. The total estimated cost is $113,000,000 for capital and support. Construction is estimated tobegin in Fiscal Year 2015-16. The scope as described for the preferred alternative is consistent with the project scope programmed by the Commission in the 2010 State Transportation Improvement Program. A copy of the MND has been provided to Commission staff. Due to potential impacts to hazardous waste, visual resources, hydrology and water quality, noise, biological resources, and traffic, an Initial Study was completed for the project. Based upon environmental studies and proposed environmental commitments, including minimization and avoidance measures, restoration activities, and incorporation of BMPs, the project will not have a significant effect on the environment. As a result, an MND was completed for this project.

In April 2018, it was reported that the RCTC requested state funds to cover most of the $117 million cost of the long awaited Route 71/Route 91 interchange rework, and the California Transportation Commission could approve the request in May. Riverside County officials proposed putting up $23.4 million, or 20 percent of the price tag. However, there’s one giant qualification: Even if the Riverside County Transportation Commission manages to win a promise to fund the project, the dollars would come from a pot of money generated by California’s controversial raising of the gasoline tax increase last year through SB1 and there is a movement under way to repeal the tax increase. Parsons Transportation Group did an environmental analysis in June 2011, then updated it in November 2014, a commission report states. Because of the time that has elapsed, officials say the analysis needs to be updated again. That effort received a $2 million boost earlier this year from the state transportation agency. As for the project, the centerpiece is a new sweeping, multi-lane flyover ramp that would connect eastbound Route 91 with northbound Route 71. It would also reconfigure the eastbound Route 91 ramp between Green River Road and the Route 71/Route 91, the report states. If the state commission funds the interchange, and if the gas tax survives, construction could start in 2019 and take about two years.

In November 2018, it was reported that a new westbound Route 91 lane at the Riverside-Orange county line that would help relieve severe congestion has been given the green light, but transportation officials are abandoning the idea of turning off Green River Road ramp meters. After sometimes confusing rush-hour experiments in June, September and October, Caltrans has concluded that switching off the Green River signals altogether — or allowing two cars to go with each green signal instead of one — won’t help. Trial results were presented at a Riverside County Transportation Commission subcommittee meeting Monday, 11/26/2018. But the panel set the stage for construction of the westbound general-purpose lane, which would extend from Green River to the Route 241 toll road. David Thomas, the commission’s toll project manager, said the lane could shave as many as 15 minutes on the morning drive from I-15 to the Orange County line. The panel — the Western Riverside County Programs and Projects Committee — recommended moving forward with the westbound lane, and the full commission is expected to approve those plans in December. Construction is estimated to cost $36.2 million. Environmental studies are underway and design is expected to be completed by the end of 2019, a report stated. Construction would begin in 2020 and be completed by fall 2021. With respect to the ramp meters, it was noted that the experiment with two cars per green light was was carried out over three days — Oct. 1-3 — then discontinued. Sheldon Mar, a traffic consultant, said just 32 percent of motorists proceeded on green with another car on the first day of the two-per-green trial. He said that rate increased to 62 percent the second day and to 67 percent on the third. After the meeting, spokeswoman Jocelyn Whitfield said Caltrans did not intend to do any more experiments. The experiment did show that turning off ramp traffic signals slashed delays driving west on Green River in the morning by 5 to 10 minutes; however, delays on the mainline of Route 91 increased 1 to 3 minutes. Further, once commuters realized Green River Road was moving more efficiently, some abandoned the freeway, causing Green River delays to increase. Overall, the change created more delay than it saved; additionally, switching off the signals induced hundreds of commuters to dangerously merge into Route 91 traffic well before the on-ramp meets Route 91.

The agency also agreed to continue studying controversial proposals for elevated lanes down the median of the existing highway, or alongside it, and a tunnel between Orange and Riverside counties through the Santa Ana Mountains (see Orange-Riverside County Connector below for more details).

In March 2020, the CTC approved the 2020 STIP, which continued the programmed funding for PPNO 0071E "B Canyon Wildlife Crossing Corridor (14S-04)". This project is in Western RIV, about 0.4 mi E of the RIV/ORA county line, about 1.8 mi SW of Prado Dam, and 0.7 mi W of Green River Road.

In June 2017, it was reported that a 41-year-old mural in Corona's Prado Dam, near the intersection of Route 71 and Route 91, that residents throughout the area want to see preserved but could be dismantled by the U.S. Army Corps of Engineers does not qualify as a historic landmark. Spokesman Greg Fuderer said that following a months-long analysis, the Corps' Los Angeles District staff determined that the beloved spillway display does not meet the criteria for listing on the National Register of Historic Places. The preliminary finding is slated to be finalized by July 10. The Corps specifically looked at whether the mural could be eligible for recognition as a national treasure using the "exceptional significance" standard, but found no validation, including lack of "distinctive characteristics of a type, period or method of construction" and no "information to contribute to our understanding of human history." The Corps acknowledged "the importance of the mural to the local community," but did not believe that served to justify preserving it, Fuderer said. The cities of Corona, Eastvale and Norco have all passed resolutions urging restoration and preservation of the mural. Riverside County Board of Supervisors Chairman John Tavaglione has also expressed support. The display, situated inside the flood control channel for the Santa Ana River, was painted in May 1976 to celebrate America's 200th birthday. More than 30 Corona High School students spent several weekends voluntarily working on the project.

In January 2014, the CTC authorized relinquishment of right of way in the county of Orange, to the Orange County Flood Control District, a political entity governed by the Orange County Board of Supervisors, along Route 91 between the boundary common to Orange and Riverside Counties, and 0.7 miles westerly thereof, consisting of collateral facilities. The Orange County Flood Control District, by resolution dated February 9, 2010, waived the 90-day notice requirement and agreed to accept title upon relinquishment by the State.

According to the Orange County Register, there are also plans to extend the Route 91 Express Lanes in a 12-mile stretch of Route 91 between Route 241 and Pierce Street in the city of Riverside. The preferred plan calls for the extension of Route 91 toll lanes, creating four toll lanes — two eastbound and two westbound — between the Riverside County line and Pierce, which is about three miles east of I-15. It also would add a general-purpose lane on each side of Route 91 and would create entries to Route 91 toll lanes from I-15 at Hidden Valley Parkway to the north and Cajalco Road to the south. The 12-mile stretch of Route 91 is traveled by an estimated 280,000 to 300,000 motorists each day. By 2030, that number is expected to skyrocket to some 425,000 motorists. Extending the toll lanes along the full 12-mile stretch and adding connectors from I-15 is estimated to cost $1.3 billion. About $300 million would come from Riverside County's Measure A, a half-cent sales tax for transportation projects in that county. The bulk of the remaining cost — some $1 billion — would come from the sale of private bonds, to be repaid by funds collected from motorists using the new toll lanes. Transportation officials hope to follow a design-build model — similar to the concept that allowed for the quicker expansion of Route 22; this would permit much of the improvements to be finished by the end of 2015.

In December 2009, the CTC received information on a proposal to amend the 2008 State Transportation Improvement Program (STIP) to reprogram $2,000,000 Regional Improvement Program (RIP) funds from the Route 91/Route 71 Interchange and Connectors project (PPNO 0077G) to a new Route 91 Corridor Improvement project (PPNO 0077J) in Riverside County. The Corridor Improvement project will reduce congestion and improve mobility within the corridor limits by constructing: one mixed-flow lane, in each direction, from Route 241 to Pierce Street, a collector/distributor system from Lincoln Avenue to I-15, a high occupancy toll (HOT) lane and/or conversion of one existing high occupancy vehicle (HOV) lane, in each direction, from the County Line to I-15, and a HOT median direct connector at the Route 91/I-15 interchange.

In October 2010, AB 2098 was signed, which allows the Riverside County Transportation Commission to utilize the “design-build” process for the 91 Corridor Improvement Project. Design-build permits the lead agency on a publicly funded project to keep procurement and contractor hiring under one roof, in contrast to “design-bid-build,” which requires dividing up the design and construction phases of a project between different entities. Design-build can shave three to five years off the time it takes to complete a project. It was estimated that 18,000 jobs would be created by the $1.3 billion project, which is slated to get under way in early 2012 and reach completion by late 2015. The project calls for an eight-mile extension of the two eastbound toll lanes that currently stop at the Riverside-Orange County line. Improvements will also be made to the I-15/Route 91 interchange in Corona and various roads that parallel Route 91.

The RCTC is preparing to launch construction of the makeover of Route 91 by late 2013 or early 2014. That massive undertaking, besides constructing toll lanes, entails adding two general-purpose lanes, replacing overpasses and building a sweeping connecting ramp that will drop northbound I-15 commuters into the new Route 91 express lanes. There are also plans for HOT lanes on I-15 once the Route 91 construction is complete.

In July 2011, it was reported that the $1.3 billion project to widen Route 91 through Corona and add two toll lanes in each direction must wait to receive a federal grant that transportation officials say is necessary to start the work. Specifically, the project could not proceed without the $446 million federal loan, and said loan was not in the Summer 2011 route of federal loan commitments for road and transit projects. If officials must wait to reapply for the $446 million loan until 2012, it would potentially delay the start of construction of the lanes until 2013, thereby moving the opening from 2017 to 2018.

In December 2011, the US Department of Transportation approved $20 million in TIGER funding for the Route 91 corridor. This payment will support a TIFIA loan that will finance up to one-third of the costs of the $1.3 billion, 8-mile extension of the Route 91 Express Lanes. The project will extend the Route 91 Express Lanes from the current eastern terminus at the border of Orange and Riverside Counties eastward to I-15. Additionally, one general-purpose lane will be added to the facility in each direction along the project route.

In October 2012, the CTC approved for future consideration of funding a project that will widen the Route 91 Corridor, including constructing one mixed-flow lane in each direction, one auxiliary lane in each direction, highoccupancy or tolled express lanes, and direct high-occupancy or tolled express lane connections between Route 91 and I-15. The project is programmed in the 2012 State Transportation Improvement Program. This project is included in the Design-Build pilot program. The total estimated cost for capital and support is $1,300,517,000. 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 in the 2012 State Transportation Improvement Program.

In March 2013, it was reported that the Budget and Implementation Committee for the RCTC approved a multi-million-dollar financing plan that calls for the issuance and sale of up to $475 million in Riverside County Transportation Commission sales tax revenue bonds (limited tax bonds), and up to $275 million in county transportation commission toll revenue bonds. The plan also includes a $435 million Transportation Infrastructure Finance and Innovation Act (TIFIA) loan from the U.S. Department of Transportation. These funds will be used to make improvements along Route 91 from the Orange County line to about Pierce Street in Riverside, including upgrading the interchange with I-15. The work would complement ongoing I-215 construction that includes widening as well as improvements to the Route 60/I-215 interchange

Route 91 Toll Lanes CoronaIn May 2013, it was reported that the Riverside County Transportation Commission on Tuesday, May 8, 2013, approved a $632.6 million contract to widen Route 91, including the toll lanes, through Corona. The contract is a major element of the $1.3 billion Route 91 Corridor Improvement Project. The $1.3 billion figure includes the new contract and other money spent acquiring land, designing the project and doing an environmental study. Construction is scheduled to begin in early 2014. Preliminary work could start this year and the lanes are expected to open by 2017. The project will replace carpool lanes with two toll lanes in each direction that will connect to toll lanes already in Orange County. Also, a fifth convention lane will be added in each direction. Without the toll lanes, 22 regular lanes would be needed to manage rush-hour congestion. Besides adding lanes, the project will rebuild seven interchanges and provide a connector from northbound I-15 to the Route 91 toll lanes. Street improvements in Corona and additional express bus service also are part of the project.

In July 2013, it was reported that the Riverside County Transportation Commission has announced the sale of bonds to pay for the construction, operation, and maintenance of the project. The funding ensures that work on the highway widening and new toll lanes in Corona will begin by the end of the year, even as land acquisition along the highway continues. Completion is set for 2017. The project will add at least two lanes of capacity to Route 91 at its most congested points through Corona. Toll lanes will be connected in a way that will take commuters traveling north on I-15 directly to the toll lanes. In addition, funding will rebuild seven interchanges and improve access from local streets to on- and offramps.

In October 2015, nine construction workers were injured, three critically, after an on-ramp bridge that is being constructed along Route 91 in Corona partially collapsed. The partial collapse occurred about 11 p.m. as workers were lowering the bridge into place at East Grand Boulevard, according to a news release from the Riverside County Transportation Commission. The jacking operation failed, which led to the bridge deck dropping more than a foot before it hit the wooden support beams. Those beams subsequently struck the workers, causing their injuries, the release stated. The construction was part of the 91 Project, which is adding regular and tolled express lanes, as well as auxiliary lanes and direct express lane connectors between Route 91 and I-15. Subsequent to the collapse, the determination was made to demolish and reconstruct the damaged off-ramp amid concerns about the structural integrity of the 750-ton bridge that spans East Grand Boulevard in Corona. It was also noted that engineering reports revealed deficiencies prior to the collapse, such as deficiencies in the bridge’s temporary supports that were noted by an assistant county engineer the day before the collapse. Those issues – among the many elements being investigated by CalOSHA, Caltrans and Washington, D.C.-based KCE Structural Engineers, which was hired by project contractor Atkinson Walsh – were reportedly corrected prior to the faulty lowering, engineering reports show. Water dripping from a light fixture on the underside of the bridge, which was also noted by an assistant engineer the day before the bridge was lowered, was placed on a list “to be addressed later.” The day after the collapse, Atkinson Walsh employees punched through the vent holes of the bridge and released 12 to 25 tons of water from the bridge, engineering reports show. The new bridge, which will be paid for by Atkinson Walsh, will not be built using the lowering process.

In December 2015, it was reported that ramps connecting Grand Boulevard to Route 91 in Corona will be permanently closed in December 2015. Drivers will be diverted to alternate ramps currently undergoing improvements as part of the Route 91 expansion project. The eastbound Grand Boulevard off-ramp is expected to close on Dec. 2, with the westbound on-ramp to follow on Dec. 14.

February 2016 saw Coronagate, a 55-hour closure of Route 91 through Corona. This closure allowed crews to complete three major facets of a $1.4 billion highway expansion at once – instead of doing piecemeal work over the next three months. Crews completed three major projects:tearing down the west side of Maple Street bridge, erecting a frame to support construction of a flyover ramp from Maple to WB Route 91 and paving nearly a mile of three EB Route 91 lanes near I-15. The steel beams installed across Route 91 were the largest portion of the flyover bridge project, but wooden framework is also required to enable concrete pouring.

In September 2016, there was an update on the ongoing $1.4 billion project to widen Route 91 from the Riverside County line in Corona to Pierce Street just past I-15 interchange in Riverside. Headed by the Riverside Transportation Commission, the project will add one regular lane and two express toll lanes in each direction, including the building of 11 new bridges, widening of 21 existing bridges, improving six interchanges, building 95 retaining walls and erecting 287,000 sq. ft. (26,663 sq m) of sound walls. The construction cost for the bridges alone is between $160 million and $175 million. Work began in 2014 and is expected to be complete in 2017. The project includes extensive use of pile driving, the common method of using large hydraulic hammers to construct foundations to support the bridges. Current construction also includes drainage and wet utility installations, retaining wall installation, bridge construction, concrete and asphalt paving, city street improvements and infrastructure installation for toll operations. Workers will apply 210,000 cu. yds. (160,556.5 cu ) of paving, add 90,000 linear ft. (27.4 m) of new drainage and relocate 92 full utility systems. Crews also will use large amounts of steel beams and lumber for the false work and formwork. Concrete and rebar will be used in the bridge structure. Funding for the project is provided by a combination of federal, state and local sources as well as toll revenue bonds. The express lanes will be fully funded by tolls from drivers who choose to use the lanes. Toll revenue will be used to repay the federal loan. The project is divided into 10 segments along Route 91 and south on I-15. The segments make it easier to report what work is currently taking place. The Riverside County Transportation Commission purchased about 200 full or partial properties for project right-of-way needs. The project has about 35 subcontractors including All American Asphalt of San Fernando, Calif., for asphalt paving; Drill Tech Drilling and Shoring of Antioch, Calif., for foundation drilling and shoring; Tipco Engineering of Bellflower, Calif., for driven steel piles; Martinez Steel of Fontana, Calif., for reinforcing steel fabrication and installation; Select Electric of Norwalk, Calif., for electrical, communications and toll infrastructure; SSL LLC of Scotts Valley, Calif., for mechanically-stabilized earth walls; and EECOM of Los Angeles for design and engineering.

In March 2017, it was reported that after three years of closures and construction, commuters on Route 91 in Corona will finally see some relief. The new toll lanes and general lanes are opening Monday, March 20, 2017. The $1.4 billion project on one of the region’s most congested freeways has added two toll lanes and one general-use lane in each direction on an 8-mile stretch from I-15 west to the Orange County line. The milestone represents the culmination of a decade of work on the biggest project the agency has ever handled. Crews also built or widened 32 bridges, improved five interchanges and realigned and repaved local streets.

In June 2018, it was reported that this project was honored in the 11th annual America’s Transportation Awards. Sponsored by AASHTO, Socrata, AAA and the U.S. Chamber of Commerce, the 11th annual America’s Transportation Awards competition recognizes transportation projects in three categories: Quality of Life/Community Development, Best Use of Technology and Innovation and Operations Excellence. California DOT (Caltrans) won in the large category (projects costing more than $200 million) for its Route 91 Corridor Improvement project, and in the Best Use of Technology and Innovation category for Caltrans' Route 1/Pfeiffer Canyon Bridge Replacement. Caltrans also won and award in the medium Operations Excellence category for the Route 191 Realignment Project: Taming the Curves.

In November 2018, it was reported that new toll lanes on Route 91 in Corona took in nearly $48 million — three times as much as expected — in their first full year and are on pace to generate $50 million this fiscal year. The rosier-than-anticipated results, detailed in a report to a regional transportation panel, spurred cries that tolls are too high and calls for spending surplus revenue on improvements to the mainline Route 91 that could ease congestion. Riverside County Supervisor Kevin Jeffries, who sits on the Riverside County Transportation Commission’s panel, said the extra money collected “beyond our wildest dreams” should be put to good use. “To the extent that we can do so, we should reinvest those toll revenues right back into the corridor to make the necessary improvements to make the corridor flow better.” While it is true revenue exceeds expectations, and the Riverside Transportation Commission staff welcomes the idea of spending surplus money on improvements, the agency has significant expenses associated with operating the toll lanes and paying off a federal loan and toll bonds. Those expenses total $40.3 million for the current fiscal year. Costs are expected to reach $47.8 million in fiscal year 2021-22. The commission could use surplus dollars to fund a new flyover connection between Route 71 and Route 91, expanded Metrolink commuter train service in the Route 91 corridor and a new westbound lane between Green River Road and Route 241. But half of surplus money allocated for such projects — except for the 71-91 and another project — must be used to pay down the federal loan.

Riverside County — I-15 to Riverside

High Occupancy Toll Lanes - Corona/I-15 to Route 60/I-215

In July 2019, it was reported that the RCTC is considering an ambitious plan for additional HOT lanes in the county:
(Source: $$ Press Enterprise, 7/6/2019)

In September 2019, it was reported that Riverside County supervisors have formally declared their opposition to a proposal to install express toll lanes on the Riverside (Route 91) Freeway between Corona and the Route 60/Route 91/I-215 interchange, based mainly on lack of justification for the lanes. The 4-0 vote by the Board of Supervisors, with Supervisor Chuck Washington absent, conveys the county's official position to the independent RCTC's action on July 10 to initiate a study of the feasibility of placing toll lanes on both the east- and westbound sides of Route 91 between I-15 and the Route 60/Route 91/I-215. The new toll lanes, stretching 14 miles, would span the entire east- west length of the city of Riverside, whose council members last month declared opposition to the proposal in a 6-1 vote. RCTC officials have stated publicly that the concept is in the nascent development stage and may never move forward, though the feasibility study will continue. Staff have cited the need for congestion relief on Route 91 as a driving factor. Early estimates put the cost of constructing the toll lanes at $1 billion. The County was particularly opposed to the RCTC concept that existing carpool lanes on the east- and westbound sides of Route 91 would be converted to minimum three-occupancy carry, instead of two per vehicle, which would require carpoolers with only two to a car to pay fees. That could push more commuters into standard lanes, adding to congestion, instead of lessening it. An additional lane would be constructed on both sides of the freeway solely for tolled express travel, regardless of the number of individuals in the vehicle. Note that even if RCTC decides to back away from the proposal, Caltrans, which is conducting a study of its own, may opt to pursue it.

Van Buren Blvd Interchange (~ RIV 14.052)

In May 2009, the CTC approved a project to widen the existing Van Buren Boulevard interchange (~ RIV 14.052) from four to six lanes, and construct ramp and roadway improvements in the city of Riverside. The project is programmed in the 2008 State Transportation Improvement Program, and includes local and federal funds. Total estimated project cost is $44,882,000, capital and support. Construction is estimated to begin in Fiscal Year 2008-09. The project was later rejiggered to use $16M in ARRA funds, but that fell through in August 2009 when officials realized the project was not "shovel-ready" enough to qualify for the federal help. Officials said they will look to state and local coffers to cover the needed reconstruction at Van Buren and Route 91. Upgrades to Van Buren and Route 91 -- an approximately $34 million endeavor -- include rebuilding ramps and widening the freeway overpass from four to six lanes. Timing proved to be critical when it came to the federal stimulus money. To comply with the American Recovery and Reinvestment Act's schedule, a highway project had to be ready to start construction by March 2010, said Shirley Medina, the transportation commission's programming and planning manager. A project also had to have regional impact and create jobs. The plans and right-of-way land acquisitions were not ready for the Van Buren upgrades, but they were for a project at Route 74 and I-215 project. Medina and John Standiford, the transportation commission's deputy director, expressed confidence that the $16 million needed to complete the Van Buren project will come from state coffers, most likely Caltrans. About $14 million would come from Measure A funds, $2.3 million from the transportation commission's regional coffers and $1.5 million from the city of Riverside.

In mid-January 2010, the Riverside City Council voted on whether to give a $15.5 million contract to Skanska USA to widen the bridge where Van Buren crosses the freeway, widen westbound freeway ramps, and add an eastbound ramp on Indiana Avenue. Construction of the $34.5 million project is expected to begin in February 2010 and should last 15 months.

In January 2007, the CTC considered relinquishment of right of way in the City of Riverside, consisting of 5 segments (a mix of Route 91 and I-215) along La Cadena Drive from Malta Place to Spruce Street and from Strong Street to Spring Garden Street, and a portion of Kansas Avenue between Roberta Street and Spruce Street, consisting of reconstructed and relocated city streets, frontage roads and culde- sacs.

Route 91 HOV Lanes + Widening - Adams Street to Route 60 (~ RIV 15.647 to RIV 21.528)

Rte 91 Project in RiversideThere is also a TCRP project that is adding HOV lanes between Adams Street and the Route 91/I-215/Route 60 junction. In January 2007, the CTC processed a request to reallocate some funds on this project and to update the completion schedule. The overall project consists of adding one HOV lane in each direction on Route 91 from Adams Street to the Route 60/91/215 Junction in Riverside County. The project also includes modifying the interchange, constructing retaining walls and soundwalls, and widening and reconstructing the existing roadway and bridges. Stage 1 of the project (Project #62.1) consists of widening Route 91 to provide one HOV lane in each direction from University Avenue to the 60/91/215 Junction. This project was selected in May 2001 as one of the pilot projects using Design Sequencing. The project was awarded in February 2004. The transfer of $16,300,000 from Project #62 to Project #62.1 is necessary to cover cost increases due to bid item quantity adjustments, unforeseen utility relocations, and adjustments to environmental and right of way mitigation for related changes. In order to fully fund Project #62, the Department is currently proposing to add $161,490,000 in Corridor Mobility Improvement Account (CMIA) funding. The final phase is now scheduled to finish in FY 2011/2012. In July 2010, the project was amended to increase the costs: specifically, the following changes were made: increase Environmental (PA&ED) from $2,681,000 to $3,193,000; increase Plans, Specifications, and Estimate (PS&E) from $13,070,000 to $20,262,000; increase Right of Way (R/W) from $31,682,000 to $62,157,000; increase Construction Support from $14,598,000 to $20,598,000; and decrease Construction Capital from $177,146,000 to $171,146,000.

In 2007, the CTC recommended that the Corridor Mobility Improvement Account (CMIA) fund construction of HOV lanes between Adams St and the Route 60/Route 91/I-215 interchange ($157,198K). They did not recommend funding the Route 71/Route 91 interchange and connectors ($99,014K).

By December 2007, a mitigated Negative EIR had been received on this project, as the project will involve construction activities in an area that is habitat to the Stephen’s kangaroo rat, a federally listed threatened species. The project will also result in the disturbance of riparian habitat. The total estimated project cost, support and capital, is now $232,777,000, provided by $24,263,000 in Regional Improvement Program funds, $3,700,000 in Traffic Congestion Relief Program funds, $47,616,000 in Congestion Mitigation and Air Quality funds, and $157,198,000 in Corridor Mobility Improvement Account funds. It is now estimated to begin construction in Fiscal Year 2010-11.

In August 2011, the CTC approved $157.2 million in funding from the state's Prop. 1B bond program, which voters approved in 2006, to add a car pool lane to Route 91 from Adams Street to the Route 60/Route 91/I-215 interchange.

In January 2012, it was reported that the project to widen Route 91 in Riverside will cost between $17 million and $21 million more than initially estimated because the job’s low bidder has been disqualified. Officials opened bids on 12/8/2011 for the project to add car pool lanes along six miles of east- and westbound Route 91 from Adams Street to the Route 60/Route 91/I-215 interchange. Since then, contractors and Caltrans officials have traded letters and worked to resolve a host of issues ranging from estimates of how long the job would take to not including enough minority contractors in the process. A Southern California Congresswoman also has weighed in on behalf of companies in her district, according to letters associated with the project. Atkinson Construction was the apparent low bidder, estimating that it could build the lanes for $108.2 million, nearly $18 million lower than any of the competitors for the job. Less than two weeks later, the company was deemed “noncompliant” because it failed to submit certifications for painting standards and because Atkinson used a different way of calculating how many days the job would take, compared to other companies. SEMA Construction, which had the second-lowest bid at $125.9 million, called Atkinson’s claim they could build the project in 212 days “irresponsible” and “unrealistic” in a letter protesting the Atkinson bid to Caltrans officials six days after the bids were opened. Caltrans officials disqualified Atkinson on Dec. 20, and said SEMA was the lowest responsive bidder. Soon after, a fencing subcontractor for Atkinson protested SEMA’s bid, saying the company failed to meet a 7 percent goal of hiring minority contractors. The same complaint to SEMA’s bid was raised by Rep. Judy Chu, D-Monterey Park, and Flatiron Construction, who submitted the third-lowest bid on the car pool lane project. SEMA is moving forward with the bid, saying they acted in good faith to try to partner with minority businesses but fell short of the 7% goal. Caltrans can award a contract to a company that doesn’t meet the minority hiring standard if the company can demonstrate it did enough to solicit job estimates from minority-owned subcontractors.

In March 2012, ground was broken for the Route 91 widening. This will complete the HOV lane from Los Angeles County to the junction with Route 60. Construction of the $232 million project is being overseen by Caltrans. SEMA Construction is the general contractor. About 1,500 jobs will be created by the project, according to estimates. Completion is scheduled for late 2015. According to SEMA’s bid, it has 570 working days — about 2½ years — to finish the job. That doesn’t count utility relocations and land clearing that has already happened. For example, since early 2011, crews have been working relocating water, electrical and gas lines beneath, atop and along the freeway. For example, crews installed new electrical lines and power poles around the Arlington Avenue exit ramp from westbound Route 91, to allow for the ramp’s redesign. The construction will affect downtown Riverside. 14th Street, one of the city’s busiest ingress and egress points to downtown offices, will be cut in half. The entire bridge will be replaced with a new overpass, one portion at a time. Entrance and exit ramps to the new 14th Street bridge also will get a serious update. The new ramps will be braided, like those along I-215 in San Bernardino near Inland Center Drive, so that traffic getting on the freeway and exiting drivers do not conflict. 14th Street will never close entirely for an extended period, but Ivy Street and Cridge Street will close so crews can demolish the bridges and replace them. The railroad bridge between Cridge and Ivy is also coming down and being replaced so that it can span the widened freeway.

In June 2019, the CTC allocated $4,272,000 for the locally-administered Local Partnership Program (LPP) (Formulaic) Pachappa Underpass (Route 91 HOV Remnant Work) project (PPNO 1239) (08-RIV-91 18.4/20.7) (PPNO 08-1239 ProjID 0816000080).

In May 2017, the CTC authorized relinquishment of right of way in the city of Riverside along Route 91 on Mulberry Street and Lime Street (08-Riv-91 PM 19.92/20.37), consisting of collateral facilities. The City, by freeway agreement dated July 13, 2010, agreed to accept title upon relinquishment by the State. The 90-day notice period expires April 30, 2017.

Route 91/I-215/Route 60 Connector (~ RIV 21.497)

There is a significant project to reconstruct the Route 91/I-215/Route 60 interchange. The project includes rebuilding the Spruce Street bridge; relocating the existing eastbound on-ramp to Route 60 from Orange Street to Main Street; and widening the existing highway undercrossing bridges at University Avenue, Mission Inn Avenue and Third Street. There are also plans to replace the existing southbound (to I-215) loop ramp with a direct freeway-to-freeway connector, as well as replacing the northbound to westbound (to Route 91) loop ramp with a direct freeway-to-freeway connector. There are also plans to remove the existing I-215 southbound off-ramp and northbound on-ramp at Spruce Street. These ramps will be relocated to Route 91 as an eastbound off-ramp and a westbound on-ramp at the new Spruce Street overcrossing bridge. The project will also realign East La Cadena Drive between 1st and Spruce Street, and provide a grade separation at the railroad crossing, as well as realigning West La Cadena Drive to accommodate the new interchange connectors. The Route 91 main line will be widened, and auxiliary lanes added between University and the 60/91/215 interchange. Additionally, I-215 (Route 60) will be widened from the 60/91/215 interchange to the 60/215 junction, including extending the existing carpool lanes from University Avenue to the 60/215 junction, and providing auxiliary lanes leading to and departing from the new freeway connectors. The existing I-215 (Route 60) Blaine Street, Iowa Avenue and Linden Street overcrossing bridges will be reconstructed to span the new freeway widening, and the existing I-215 (Route 60) Blaine Street, University Avenue and Central Avenue/Watkins Drive interchanges will be improved, including ramp widening. Sycamore Canyon Boulevard will be realigned at Central Avenue. The project will construct a new interchange at Martin Luther King Boulevard, and remove the existing El Cerrito Drive interchange. The existing railroad overhead bridges at Down Street and Chicago Avenue will be widened. At the 60/215 junction, a truck by-pass connector will be constructed from southbound I-215 to eastbound Route 60 and southbound I-215. On Route 60, the existing Day Street interchange will be modified. On I-215, the Box Springs Road interchange will be rebuilt with an overcrossing bridge. Lastly, there will be a a concrete barrier on northbound I-215 at the junction to westbound Route 60. This project has taken three years, cost over $317-million, and should conclude in Spring 2008. Caltrans officials plan to open two new connector ramps by the end of 2007, including one that soars 72 feet high and measures just over a mile long.

Route 91 General

Freeway from Route 110 to Route 215; planned as freeway, never upgraded, between Route 405 and Route 110. The first segment (as freeway) opened in 1968; the last segment opened in 1975.

Orange-Riverside County Connector

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

The Irvine Company has proposed stacking a freeway on top of railroad tracks through Santa Ana Canyon to relieve traffic on the Riverside Freeway. The 10-mile freeway would be built above a heavily traveled rail line from Interstate 15 in Riverside County to the Foothill tollway in northeast Orange County, running parallel to the Riverside Freeway. The result would be side-by-side freeways passing through the canyon that links Orange and Riverside counties. In 2005, the estimate for construction of a double-deck, elevated road would be $50 million to $80 million per mile. The cost to build a 10-mile, six-lane freeway could be anywhere from $360 million to $4.8 billion.

There have also been proposals to ease traffic by drilling a tunnel or carving a highway through the Cleveland National Forest. The tunnel proposal involves an 11-mile tunnel that would run from Route 133 in Irvine to Cajalco Road at I-15. A different tunnel proposed by the Riverside County Building Industry Assn. would cut through the mountains from Interstate 15 and loop back to the Riverside Freeway, where it would connect to the Foothill tollway along four miles of double-decked lanes. Again, this tunnel would connect to Cajalco Road, which turns into the Ramona Expressway and runs past the former March Air Reserve Base, one of the region's newest cargo airports. According to a 2005 report, two route options (for new relivier routes) currently under study call for building one or more tunnels from the I-15 Freeway through the Cleveland National Forest to Orange County. One starts at Cajalco Road in Corona and the other at Lake Street or Nichols Road in Lake Elsinore. Both tie in near the Route 133/Route 241 interchange in Irvine. Either route could have one continuous tunnel at least 10 miles long or multiple shorter tunnels.

In 2002, motorists made about 250,000 trips a day on the Riverside Freeway. In 2005, Route 91 — which now includes four toll lanes — carries 264,000 cars a day. In 2020, there could be as many as 452,000. As the population grows, the traffic slows — down to 5 mph now during rush hour. The state has even gotten into the act; ACR 81, passed in 2002, calls for a study for such a Riverside to Orange County Transportation Corridor. The North County Times had an article on a commuter meeting on this route that explored five corridors: existing Route 91; the parallel railroad corridor to the north; Lake Street/Nichols Road and I-15 in Lake Elsinore to Route 133 and Route 241 in Orange County; Cajalco Road and I-15 in south Corona to Route 133 and Route 241; and the Ortega Highway (Route 74). Within each corridor, there are multiple options. Freeways, railroad tracks and exclusive bus lanes all are on the table. All told, there are a dozen potential fixes under study, all entailing a different mix of potential improvements. One final preferred fix is expected to be named in December 2005, when a $3.3 million study is completed.

According to the Orange County Register, a November 2005 study suggested that lanes should be added to Route 91 to ease congestion, and commuters should be encouraged to use the Route 241 toll road instead of Route 55. The report also recommended that an elevated roadway parallel to the 91 should be further explored and a detailed geotechnical study should be conducted on the proposed tunnel beneath the Cleveland National Forest to learn if the water table makes such a concept too expensive - and a reason to drop the idea. Specifically, the study suggested adding lanes to Route 91 in segments, up to three lanes in one stretch. Building them and other freeway improvements would cost $670 million. It is also suggested to reduce the tolls on Route 241 to encourage traffic to take that route. In compensation, the Orange and Riverside transportation agencies would build additional lanes for the toll road web. If enough added cars and trucks jump onto Route 241 and related toll roads, enough tolls would be collected to cover the reduced price of the toll. Widening the lanes and other changes could cost $470 million. There is also the possibility of creating a roadway just north of Route 91 for a four-lane, mostly elevated highway that could go over wildlife corridors; this would cost an estimated $2.7 billion. The tunnel approach, as well as widening Route 74, are currently cost prohibitive, and potentially geologically prohibitive.

As more details emerged, the plan proposed a freeway through the forest and a double-decking Route 91. Specifically, the regional transportation panel decided to recommend building those new roads, and add a few lanes to the 91, to accommodate the roughly 450,000 cars forecast to travel daily between the counties by 2030. The panel didn't specify whether the forest freeway, extending from I-15 and Cajalco Road to Irvine, would go either in a long, continuous tunnel under the Santa Ana Mountains or a series of short tunnels interspersed with overland highway sections. It would not be built entirely above ground through the Cleveland National Forest, however. If transportation officials wanted to put all traffic on Route 91, they would need to widen it to 22 lanes. The $10 billion preferred plan does call for some widening on Route 91 in Riverside County, to match the number in Orange County, Rahimian said. With those improvements in place, officials could accommodate the forecast growth either by constructing a six-lane elevated highway over the 91, or punching a six-lane freeway through the forest. Cost projections include $6 billion for the forest-tunnel highway. The Corona elevated highway's price tag is pegged at $2.7 billion. [The] second deck would partially cover Route 91 and would run between I-15 and Route 241 toll road in Orange County. It would empty directly onto Route 241.

[Linkj to Press Enterprise Image]In February 2010, it was reported that an 11.5-mile tunnel between Corona and Irvine through the Santa Ana Mountains is technically feasible and deserves more study, although it is well out of the price range of public agencies. Based on the tests by Irvine-based engineering firm Kleinfelder, there are no "fatal flaws" in building a 52-foot-wide tunnel to carry traffic and another smaller tunnel for passenger rail service and a water line. But obstacles remain, much as they did in 2007 when the feasibility study was started. Engineers have said since 2008 that the tunneling would require larger boring machines than have ever been built, and designers will have to find an answer for how to ventilate the tunnel that isn't damaging to the forest above. The estimated cost to build one of the two 53-foot tunnels and the 27-foot hole for rail and water company use would be nearly $8.6 billion. The route would be roughly from the Route 133/Route 241 junction to Caljaco Road and I-15. Currently, the counties are investigating if they could borrow for construction based on anticipated tolls. The price of a one-way trip through the tunnel is estimated to vary between $4 and $20, depending on the time of day, according to a report presented to the bi-county authority. The tunnel would be used in one direction in the morning, then reverse course in the evening to handle rush-hour traffic. Construction would not start until 2019 and take a decade, according to the current schedule.
(Source: "OC-RivCo tunnel feasible, but pricey", Dug Begley, Riverside Press Enterprise, 2/3/2010)

In July 2010, it was reported that although the tunnel was technically feasible, it was economically infeasible. At a cost of $8.6 billion, it's simply too expensive, especially since officials can't start collecting tolls until after they spend 10 years building it. The proposed 11.2-mile tunnel also faces technical and environmental issues that could slow or stop construction. The notion right now is to make the project low priority until something changes -- technology improves so much that construction costs drastically drop, they receive a large bundle of money, etc. Backers are hopefull that groundwater monitoring at least will continue. To meet rules regarding construction in national forests, 10 years of groundwater monitoring must be compiled. If officials suspend the $30,000-a-month monitoring, they would have to start all over again if the project were revived. The image to the right shows some of the issues.

Commuter Lanes Commuter Lanes

Commuter lanes exist for all of Route 91 in Los Angeles County. The eastbound lanes between Central Avenue and I-605 were opened in 1985; westbound between I-110 and I-605 in 1993, and between I-605 and the Los Angeles county line in 1994.

In Orange County, HOV lanes exist between 0.2 mi E of the Route 57 interchange and the Riverdale Avenue overcrossing. HOVs also may use the Route 91 toll road for free between the Los Angeles/Orange County line and the Orange/Riverside County line. All these lanes opened in December 1995, and are always in operation. Lanes also exists from the Los Angeles County line to 0.3 mi E of Stanton Avenue; and from 0.2 mi E of Gilbert to 0.3 mi W of La Palma. Construction started on these lanes in January 1997.

In Riverside County, HOV lanes exist between the Orange County line and Mary Street. The portion between the Orange County line and Magnolia Avenue opened in September 1992; the remainder (between Magnolia Avenue and Mary Street) opened in July 1995. In May 2001, the CTC considered an Agenda Item (TCR Project #62) to construct HOV lanes from Mary Street to the Route 60/Route 215 junction. In December 2004 and January 2005, a request was made to extend the project limits for the Route 91 High Occupancy Vehicle (HOV) Lanes project (PPNO 0092A) in Riverside County to close the gap of the HOV lane in the eastbound direction, between Adams Street and Mary Street. In September 2005, the extension of the HOV lanes from Mary Street to the Route 60/Route 215 interchange was delayed. The original construction contract was awarded in February 2004 after nearly a year of delay caused by the previous suspension of allocating new TCRP funds. The need to reconcile differences between the bid package and the completed design has resulted in additional schedule delays and additional costs. The project is now scheduled to complete in June 2007.

All HOV lanes require two or more occupants, and operate 24 hours all days.

In November 2012, it was reported that the HOV lanes in Orange County had been restriped to allow entry and exit at any time ("continuous access"), as opposed to only at specific ingress and egress points.

Naming Naming

Before 1991, the 4.7mi segment W of Route 710 had been named the "Redondo Beach Freeway" (~ LA 0.000 to LA R11.545) (named by the State Highway Commission). It was named because it traverses the City of Redondo Beach, CA, which was founded in 1881 and apparently named after the adjoining Ranch Sausal Redondo (round willow grove).

The segment of Route 91 from the western city limits of Gardena to Route 710 (~ LA 6.033 to LA R11.545) is offically named the "Gardena Freeway". It was named by Senate Concurrent Resolution No. 16, Chapter 35, in 1991. Gardena refers to the city of Gardena, which was derived from "garden" and was applied to the subdivision in the 1880s.

Edmond J. RussBridge 53-958 on I-110, the I-110/Route 91 interchange (~ LA 6.322), is named the "Edmond J. Russ Interchange". It was built in 1985, and was named by Assembly Concurrent Resolution 135, Chapter 162. [Note: According to the CalTrans logs, this bridge is actually on Route 110; thus the named interchange is at the Route 110/Route 91 junction.] Ed Russ is a former mayor of Gardena; during his term (which ended in 1982) he was able to push for the extension of the then Redondo Beach Freeway to the Route 110. This extension relieved the traffic that plagued Atresia Blvd from the end of the freeway at Broadway to Route 110. When the extension was completed in 1985, it was given the legislative name in his honor, but it was up to the private sector to produce the funds to make and install the signs for the interchange. It wasn't until 1998-99 that a group of Gardena businesspeole and citizens, led by the Gardena Valley News, began a campaign to raise the money needed. The signs were installed in the latter half of 1999.

Rudolph B. DavilaThe westbound portion of Route 91 between Figueroa Street and Central Avenue (~ LA R6.534 to LA R8.444), in the City of Carson is officially named the "Rudolph B. Davila Memorial Freeway" This segment was named in memory of Rudolph B. Davila, who was born in El Paso, Texas, and was raised in Watts, California. As a young man during the Depression, he worked in vineyards and helped restore the California missions as part of the Civilian Conservation Corps. During World War II, Rudolph B. Davila helped take out several machine gun nests and prevented a 130-man American rifle company from being slaughtered in a German ambush in Italy. According to his Medal of Honor citation, Davila’s machine gunners were caught on an exposed hillside by heavy grazing fire from a well-entrenched Germany force and were reluctant to risk putting their guns into action. Davila crawled 50 yards to the nearest machine gun, set it up alone and opened fire on the enemy. In order to observe the effect of his fire, Davila fired from the kneeling position, ignoring the enemy fire that struck the tripod and passed between his legs. Ordering a gunner to take over, Davila crawled forward to a vantage point and directed the firefight with hand and arm signals until both hostile machine guns were silenced. Bringing his three remaining machine guns into action, Davila drove the enemy to a reserve position 200 yards to the rear. When Davila received a painful wound in a leg, he dashed to a burned tank and despite the crash of bullets on the hull, engaged a second enemy force from the tank’s turret. Dismounting, he advanced 130 yards in short rushes, crawled 20 yards and charged into an enemy-held house to eliminate the defending force of five with a hand grenade and rifle fire. Climbing to the attic, he straddled a large shell hole in the wall and opened fire on the enemy. Although the walls of the house were crumbling, he continued to fire until he had destroyed two more machine guns. Davila’s “intrepid actions brought desperately needed heavy weapons support to a hard-pressed rifle company and silenced four machine gunners, which forced the enemy to abandon their prepared positions,” the citation read. Davila received a battlefield commission to second lieutenant and was initially awarded the Distinguished Service Cross, the Army’s second-highest honor. His wife, Harriet, lobbied Army officials for years to award her husband the Medal of Honor. A captain in the rifle company had said he would recommend Davila for the Medal of Honor. On June 21, 2000, 56 years later, Rudolph B. Davila, who was of Filipino and Spanish descent, along with 20 other Asian American World War II veterans, received a Medal of Honor from President Bill Clinton at a White House ceremony after an army panel reviewed their wartime actions and deemed them worthy of the nation's highest commendation for battlefield bravery. Rudolph B. Davila earned the medal for his extraordinary heroism during the offensive that broke through the German mountain strongholds surrounding the Anzio beachhead in May 1944. When asked what made him rise to his knees with a machine gun while his fellow soldiers hugged the ground, Rudolph B. Davila said, "I knew what I was fighting for, and most of the kids didn't," he said, ascribing his self-assuredness to accounts he had read of Hitler. "I had this fervour about the defense of freedom, even though I couldn't define freedom. I just knew we were going to be enslaved to Hitler if we didn't defeat him." The war ended for Rudolph B. Davila in late 1944 when a tank round exploded in a tree and shrapnel ripped into his right shoulder. Over the next six years, he underwent 13 operations on his arm and met his wife, Harriet, at a military hospital in San Francisco, California. After the war, Rudolph B. Davila earned bachelor's and master's degrees in sociology from the University of Southern California, and spent 30 years as a teacher and counselor in the Los Angeles City School District. Rudolph B. Davila was an excellent cook and gardener. He terraced his hillside yard and built retaining walls. He also built the family's house in Harbor City, California, and his retirement home in Vista, California. Rudolph B. Davila died January 26, 2002, in Vista, California, after a long illness and is survived by his children. Named by Senate Concurrent Resolution (SCR) 107, Resolution Chapter 125, on 9/7/2010.

Fullerton Police Detective Tommy De La Rosa Memorial InterchangeThe interchange of I-5 and Rout 91 (~ ORA R3.548R) in the City of Fullerton is named the “Fullerton Police Detective Tommy De La Rosa Memorial Interchange”. It was named in memory of Fullerton Police Detective Tommy De La Rosa, who at 43 years of age paid the ultimate sacrifice in the line of duty. Detective De La Rosa was born on May 12, 1947, and served his country during the Vietnam War while in the Marine Corps. Detective De La Rosa joined the Fullerton Police Department on September 26, 1980. While off duty, Detective De La Rosa liked to speak with children from neighborhoods heavy with drugs, gangs, and prostitution and urge them to be good and stay in school. On June 21, 1990, Detective De La Rosa was ambushed and shot five times during an undercover reverse sting narcotics operation, but, although gravely injured, was still able to return fire and fatally wound one of the suspects before succumbing to his injuries. Three other suspects were convicted of Detective De La Rosa’s murder and were sentenced to life without parole. Detective De La Rosa provided the public with exemplary service and dedication to his job throughout his nine-year career with the Fullerton Police Department. Named by Senate Concurrent Resolution (SCR) 28, Res. Chapter 128, Statutes of 2015, on July 22, 2015.

  1. Staff Sergeant Salvador J. Lara was born in Riverside, California, in 1920. His brother Alfonzo Lara, accepted the Medal of Honor on behalf of his late brother from President Barack Obama during a White House ceremony held on March 18, 2014. Staff Sergeant Lara died on September 1, 1945, and is buried at the Lorraine American Cemetery and Memorial in Saint-Avold, Moselle, France. Staff Sergeant Lara was one of 24 veterans awarded the Medal of Honor through the National Defense Authorization Act for Fiscal Year 2002 (Public Law 107-107) which called for a review of Jewish American and Hispanic American veterans from World War II, the Korean War, and the Vietnam War to ensure that Jewish American and Hispanic American veterans deserving the Medal of Honor were not subject to prejudice. Then-Private First Class Salvador J. Lara distinguished himself by acts of gallantry and intrepidity for his valorous actions in Aprilia, Italy, May 27-28, 1944. During the fight on May 27, he aggressively led his rifle squad in neutralizing multiple enemy strong points and inflicting large numbers of casualties on the enemy. The next morning, as his company resumed the attack, Private First Class Lara sustained a severe leg wound, but did not stop to receive first aid. Private First Class Lara continued his exemplary performance until he captured his objective. Private First Class Lara’s extraordinary heroism and selflessness above and beyond the call of duty were in keeping with the highest traditions of the United States Army and demonstrated his ability and leadership as the squad leader of a rifle squad with the 2nd Platoon, Company L, 180th Infantry, 45th Infantry Division during combat operations against a determined enemy. Private First Class Lara achieved the rank of Staff Sergeant and was awarded the Distinguished Service Cross (upgraded to the Medal of Honor on March 18, 2014), the Bronze Star, the Purple Heart, the Army Good Conduct Medal, the European-African-Middle Eastern Campaign Medal with two Bronze Service Stars, the World War II Victory Medal, the Presidential Unit Citation, the Combat Infantryman Badge, and the Honorable Service Lapel Button–World War II.
  2. Staff Sergeant Ysmael “Smiley” R. Villegas was a Mexican American who was born in March 1924, and raised in the Casa Blanca neighborhood in the City of Riverside, California. On October 19, 1945, President Harry S. Truman posthumously awarded the Medal of Honor to Staff Sergeant Villegas, presenting the medal to his surviving family. Staff Sergeant Villegas was the first Riverside County resident to ever receive the Medal of Honor and the first veteran to be buried at the Riverside National Cemetery when the cemetery opened in 1978. On March 1, 1945, Staff Sergeant Villegas’ company found itself engaged in combat against Japanese forces at the Villa Verde Trail on the island of Luzon in the Philippines, in what is known today as the Battle of Luzon. His squad was attacked by an enemy machine gun nest. Staff Sergeant Villegas took it upon himself to save his squad by destroying the nest and its occupants. For these actions, Villegas was awarded the Silver Star. On March 20, 1945, Staff Sergeant Villegas was leading his squad at Villa Verde Trail in Luzon in the Philippines, his unit advancing in a forward position, when they suddenly clashed with a strongly entrenched group of Japanese soldiers who commanded the surrounding area and were hiding in caves and foxholes. Staff Sergeant Villegas moved boldly from man to man, in the face of bursting grenades and demolition charges, through heavy machinegun and rifle fire, to bolster the spirit of his comrades. Inspired by his gallantry, his men pressed forward to the crest of the hill. Numerous enemy riflemen, refusing to flee, continued firing from their foxholes. Staff Sergeant Villegas upon his own initiative attacked five enemy foxholes, killing all of the occupants, and was mortally wounded when he attacked the sixth foxhole. Through his heroism and indomitable fighting spirit, Staff Sergeant Villegas inspired his men to a determined attack that swept the enemy from the field. The Veterans of Foreign Wars (VFW) named Post 184 in Riverside, California, the “Ysmael R. Villegas Memorial Casa Blanca Post” in his honor. A statue by sculptor Gary Courter, called Villegas Memorial, was dedicated on May 27, 1995, and is located on Main Street Civic Center Courtyard in the City of Riverside. The Ysmael R. Villegas Middle School in the City of Riverside is named in his honor. In 2014, at a memorial service to commemorate the Mexican American veterans from the historic Casa Blanca community in the City of Riverside, five of Villegas’ sisters and one brother were in attendance: Rafaela, Lottie, Helen, Martha, Pat, and Art. Staff Sergeant Villegas was also awarded the Silver Star, the Purple Heart, the American Campaign Medal, the Asiatic-Pacific Campaign Medal, the World War II Victory Medal, and the Philippine Liberation Medal.
  3. Sergeant Jesus S. Duran was born in July 1948, in Juarez, Mexico, and was the sixth of 12 siblings. He passed away on February 17, 1977, and is survived by his daughter,who accepted the Medal of Honor on his behalf from President Barack Obama on March 18, 2014, in a ceremony at the White House. The following day, she received the Medal of Honor flag from Secretary of Defense Chuck Hagel in a ceremony where Sergeant Duran was inducted into the Pentagon Hall of Heroes. Sergeant Duran, like Staff Sergeant Lara, was one of 24 veterans awarded the Medal of Honor through the National Defense Authorization Act for Fiscal Year 2002. Sergeant Duran joined the United States Army on May 13, 1968, and was assigned to Company E, 2nd Battalion, 5th Cavalry, 1st Cavalry Division (Airmobile) to support Search and Destroy missions. During his service in the Vietnam War, Sergeant Duran distinguished himself during combat operations against an armed enemy in the Republic of Vietnam on April 10, 1969. On that afternoon, upon learning that two seriously wounded troopers lay helplessly pinned down under harassing fire, then-Specialist Four Jesus S. Duran assaulted the suppressive enemy positions, firing deadly bursts on the run. Mounting his weapon on a log, he fired directly into the enemy’s foxholes, eliminating four and cutting down several others as they fled. Specialist Four Duran then continued to pour effective fire on the disorganized and fleeing enemy. His extraordinary heroism and selflessness above and beyond the call of duty, as well as his acts of gallantry and intrepidity, were in keeping with the highest traditions of military service and reflect great credit upon himself, his unit, and the United States Army. Jesus S. Duran achieved the rank of Sergeant and, upon leaving the military, pursued a career as a corrections officer at a juvenile detention center in the City of San Bernardino, California. While working there, he dedicated numerous hours of personal time to mentor youth and lead them on educational trips. Sergeant Duran married twice and had two children. He loved spending time with all of his family. Sergeant Duran also received the Bronze Star Medal, the Air Medal, the Army Good Conduct Medal, the National Defense Service Medal, the Vietnam Service Medal with four Bronze Service Stars, the Combat Infantryman Badge, the Sharpshooter Marksmanship Badge with Auto Rifle and the Browning Automatic Rifle “BAR” Machine Gun, the Marksman Marksmanship Badge with Rifle Bar, the Vietnam Campaign Medal with 1960 Device, and the Republic of Vietnam Gallantry Cross Unit Citations with Palm Device.
