    This segment is as defined in 1963.

    Pre 1964 Signage History Pre 1964 Signage History

    This route was proposed, but unconstructed before 1964. It was LRN 273. This route was defined in 1959.

    Status Status

    Route 1 to Route 405

    Unconstructed This segment is unconstructed between Route 1 and I-405. There is no traversable highway identified.

    Route 405 to I-5

    Toll Road Unconstructed Between I-405 and I-5, this segment was at one time planned for pilot toll road project. It would have been a 4-lane, 11.2 mile extension located within the Santa Ana Flood Control Channel right-of-way. Recently, the Orange County Transportation Authority voted its support for the toll road portion of Route 57. However, on 1/3/2001, a Caltrans spokesman announced that it is "very unlikely" that the department would extend a 10-year-old toll franchise agreement for the proposed SR-57 Extension project. However, the OCTA revisited the idea in early 2003. Supervisor Chris Norby, who sits on the OCTA board of directors, wants to fast-track a $1.1-million study to determine whether the 57 Extension is practical from engineering and political standpoints.

    Rte 57 Toll Road ProposalAccording to the Los Angeles Times in November 2005, Orange County transportation officials recently voted to extend Route 57 southwest along the Santa Ana River to I-405. With this vote, the OCTA board voted to hire a consultant to prepare a three-month feasibility study for a double-deck freeway above the river. The proposal still faces likely opposition from the Army Corps of Engineers, neighborhoods and proponents of a park along the river. Extending the freeway down the Santa Ana River would take commuters 6.5 miles through Santa Ana and Fountain Valley. An extension has been discussed for years. But past proposals focused on routing a six-lane freeway through neighborhoods and shopping centers in Santa Ana. Plans to build an extension above the river, instead, materialized about the same time, in 1986. One proposal called for building piers thrust into the Santa Ana River to serve as pillars for the freeway. There also has been talk about building the extension as a tollway, connecting it to the San Joaquin Hills tollway in Costa Mesa. Any proposal involving a route above the river will involve the Army Corps of Engineers, which has major flood-control jurisdiction over the river. According to a corps spokesman in Los Angeles, any plan for a freeway above a flood control channel has an uphill battle, due to impacts on the flood channel. In October 2007, the study reported its result. The study showed that the proposed eight-mile route above the Santa Ana River connecting to the San Diego Freeway would cost about $2 billion. The study identified no funding for the route, and the extension was not included among projects under Measure M, a half-cent local sales tax for transportation improvements. It also found that using a route for the extension down the river is possible but there are other challenges, such as the impacts to the environment and the neighboring communities. Santa Ana officials feel that the transportation benefits would be outweighed by the negative environmental impacts effects and reduced the quality of life for city residents.

    According to the Caltrans Page on the Route 57 Toll Road, "As proposed, this $950 million project is a 4-lane, 11.2 mile extension of Route 57 from Route 5 to Route 405 located within the Santa Ana River Flood Control Channel right-of-way. The four lanes would consist of 2 two-lane viaducts running longitudinally down the river channel. The franchisee is American Transportation Development (ATD), a partnership of Interwest Company, Inc. and Washington Group, International, Inc. ATD has requested that the required date for commencement of construction be extended from January 11, 2001 to January 11, 2007. This request was denied and the franchise was terminated in January, 2001. ATD contested the termination and it had been in litigation until it was resolved on November 14, 2003."

    Naming Naming

    This segment is named the "Orange Freeway". It was named by Assembly Concurrent Resolution No. 17, Chapter 157, in 1969. It was named because it traverses the community of Orange, CA, which was founded in 1873 (the county was created in 1889). The city was probably named to advertise one of the principal products of the district, although it may also have been named after one of the fifty-odd other Oranges in the U.S.

    The South Street overcrossing is named the "Jim Dowling Memorial Bridge". This is an unofficial name, as Caltrans signed it before the Assembly Bill passed, and the bill was then dropped. It was named in memory of Jim Downing, a victim of a drunk limousine driver around 1984 at the age of 26. It is unclear where this is on the proposed routing.


  2. Rte 57 Seg 2From Route 5 near Santa Ana to Route 210 near San Dimas.

    As of November 24, 2002, the portion from I-10 to I-210/Route 210 was signed as Route 57. Previously, this segment had been signed as part of I-210.

    Post 1964 Signage History Post 1964 Signage History

    In 1963, this segment was defined as the segment "Route 5 near Santa Ana to Route 210 near Route 10 and Pomona, passing near Industry." Note that the Route 210 referred to in this segment is the former I-10/I-210 junction in Pomona, not the current I-210/Route 57 junction in San Dimas.

    In 1965, Section 1371 split this into two segments: "(b) Route 5 near Santa Ana to Route 60 near Industry. (c) Route 60 near Industry to Route 210 near Route 10 and Pomona."

    In 1998, AB 2388 (Chapter 221) recombined these segments, and renumbered former Route 210 between the I-10 (near Pomona) to the I-210/Former Route 30 jct (near San Dimas) portion as Route 57, creating the current definition. However, in terms of postmiles, the portion of the route that runs along Route 60 is not part of Route 57.

    Pre 1964 Signage History Pre 1964 Signage History

    In 1931, the first portion of future Route 57 was defined. This portion, as LRN 19, ran from LRN 2 near Fullerton to Pomona. LRN 2 at the time was along Whittier Blvd and Spadra (later renamed Harbor Blvd). This portion of Route 57 ran along Brea Blvd/Brea Canyon Road from Harbor Blvd to the eventual US 60. (LRN 19 then continued along the US 60 routing to Pomona).

    In 1959, other portions of Route 57 were defined. The portion between Route 60 and I-10 was part of LRN 272 with an indeterminate routing. The portion between I-10 and I-210 was originally part of Route 71, and was LRN 240. This portion later became part of I-210, and was renumbered as part of Route 57 in 1998.

    The remainder of the route -- that is, the portion between former LRN 2 and present-day I-5, was not part of the pre-1964 state highway system. The specific freeway routing also appears to be post-1964. The portion of this route between Route 5 and Route 91 (LRN 43) is similar to what was LRN 180; however, LRN 180 is the same routing as 1964-1981 Route 250. LRN 180 was defined in 1933. However, a 1959 Renie Atles from the Division of Highways shows an approximate routing for what would become Route 75, penciled in for some reason as LRN 2, running between Placentia (State College) and Rio Vista from I-5 to LRN 19 near Deodara (now Lambert) at about where State College is today. At that point, it met the penciled in routing for LRN 19 and continued up to Brea Canyon.

    Route 57 was not part of the initial set of state signed routes in 1934. It is unclear when Route 57 was first signed.

    Status Status

    SR-57 Improvement Project (ORA 11.5/12.5)

    Rte 57 Improvement LogoInJune 2017, it was reported that OCTA, in partnership with Caltrans, is in the initial phase of evaluating the potential benefits and effects of extending the fifth general-purpose lane of northbound Route 57 from Orangewood Ave to Katella Avenue (~ ORA 11.779 to ORA 12.532). The project area is about a mile long and is located between Orangewood Avenue in Orange and Katella Avenue in Anaheim. The project is part of Measure M, the half-cent sales tax approved by voters for transportation improvements in Orange County. This initial stage of the project will study the benefits and potential environmental impacts of increasing capacity on the Route 57 by extending the fifth general-purpose lane to this portion of the freeway. The project’s draft environmental document is anticipated to circulate for public review and comment in mid-2018, and the environmental study phase is expected to be completed in late 2018.
    (Source: OCTA Blog, 6/20/2017)

    Rte 57 NB Orangewood to KatellaIn October 2018, the Draft EIR for the project was made available for review. The project (a joint project of Caltrans and the Orange County Transportation Authority (OCTA)), proposes to widen the northbound side of Route 57 from 0.3 mile south of the Orangewood Avenue undercrossing (ORA 11.5) north to the Katella Avenue undercrossing (ORA 12.5), a distance of approximately one mile. The project includes the construction of a 550-foot section of the fifth general purpose (GP) lane in the northbound direction of Route 57 through the Katella Avenue interchange, upgrades to the non-standard median and sight distances, and reconfiguration of the existing on- and off-ramps to improve operation between the Orangewood Avenue interchange and the Katella Avenue interchange. Caltrans is the lead agency under the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA).
    (Source for this, and the details below: OCTA Blog, 10/17/2018; District 12 Project DEA Page; State Route 57 Northbound Improvement Project: Orange County, California - District 12 – ORA-57 (PM 11.5 – 12.5) - 1213000099/EA 0M9700 - Initial Study [with Proposed] Mitigated Negative Declaration/Environmental Assessment, October 2018, Chapter 1: Proposed Project)

    The 0.75-mile segment from the Orangewood Avenue interchange to the Katella Avenue off-ramp currently has an inside HOV lane, four to five GP lanes, and one auxiliary lane. The auxiliary lane merges with the fifth GP lane located between the Orangewood Avenue loop on-ramp and the Katella Avenue off-ramp. The merge results in a gap of 0.75 mile on the mainline with only four GP lanes between where the fifth GP lane merges with the auxiliary lane north of the Orangewood Avenue loop on-ramp and where the fifth GP lane resumes north of the Katella Avenue off-ramp. The loss of both the auxiliary lane and the fifth GP lane within the 0.75-mile mainline segment results in excessive lane changes and congestion. The proposed Project addresses this existing gap in the fifth lane, as well as several nonstandard design issues representing the most critical features adversely affecting mainline operations in this segment of the freeway (Orangewood Avenue to Katella Avenue). Route 57 is currently congested during peak periods, and the future northbound Route 57 mainline between the Orangewood Avenue and Katella Avenue interchanges is forecast to lack sufficient capacity, which will result in poor mobility. Further, several existing nonstandard design features, including weaving and merging issues, adversely affect freeway operations.

    A total of four alternatives are evaluated in detail for the proposed Project. Three Build Alternatives and the No Build Alternative. The three Build Alternatives include Alternative 2, Alternative 2A, and Alternative 2B. The latter two Build Alternatives originated as options to Alternative 2, but are sufficiently different that they are evaluated as full alternatives. Alternative 1 is the No Build Alternative. The three build alternatives include the following features (although with other factors not relevant for the site):

    • Construct the missing section of the fifth GP lane between the Katella Avenue northbound off-ramp and the bridge structure over Katella Avenue (Katella Avenue UC Bridge);
    • Widen and implement seismic retrofit by strengthening two Route 57 bridge structures: Orangewood Avenue UC Bridge (No. 55 0481) and the Santa Ana River Bridge (No. 55 0400);
    • Restripe the northbound HOV lane and the mainline GP lanes from about 640 feet south
    • of the Orangewood Avenue eastbound loop on-ramp to 600 feet south of the Katella
    • Avenue UC Bridge;
    • Modify the two existing eastbound Orangewood Avenue loop on-ramp turn lanes from free right turns to a newly configured 90-degree traffic controlled intersection located slightly east of the current location;
    • Construct a full intersection at Orangewood Avenue and the NB Route 57 ramps;
    • Increase the weave length between the Orangewood Avenue on-ramp(s) and the Katella Avenue off-ramp;
    • Utilities within the project area will remain protected in place. Coordination with utility companies during final design as well as construction would be required to accommodate existing utilities and avoid conflicts.
    • Add a second lane to the Katella Avenue off-ramp;
    • Provide replacement landscaping and permanent irrigation with a three-year plant establishment period (PEP);
    • Improve bridge deck surfaces and spot locations through pavement rehabilitation; and
    • Coordinate metered on-ramps and the traffic signals on Orangewood Avenue to control congestion.
    • Construct a continuous Auxiliary Lane between Orangewood Avenue and Katella Avenue.
    • Include considerations for OC Park / OCFCD trail and bike path users, and reconstruct sidewalks, curbs, and gutters to meet current ADA Standards (28 CFR 35.151)

    The build alternative unique features are:

    • Alternative 2: Modify Orangewood Avenue On-Ramp, Widen Katella Avenue Off-Ramp (Widen 3 Bridges). Major construction under Alternative 2 would widen three bridges; the Orangewood Avenue UC Bridge (No. 55 0481), the Santa Ana River Bridge (No. 55 0400), and the Stadium OH Bridge (No. 55 0399). Widening the Orangewood Avenue UC would allow the on-ramp merge point with the through traffic to be extended several hundred feet to the north. Extending the merge point would allow merging traffic to have a longer distance to gain speed to match the speed of mainline traffic. Widening the Santa Ana River Bridge allows for an adjustment of the overall mainline alignment to address the nonstandard design features (i.e. median width and stopping sight distance on horizontal curves). Widening the Stadium OH Bridge would accommodate the fifth GP lane.
    • Alternative 2A: Eliminate Orangewood Avenue On-Ramp, Construct Katella Avenue Off Ramp (Widen 2 Bridges, Construct New Stadium OH Bridge). Similar to Alternative 2, major construction under Alternative 2A would widen the Orangewood Avenue UC Bridge (No. 55 0481) and the Santa Ana River Bridge (No. 55 0400), but also would construct a new bridge. The freeway HOV and GP lanes would be restriped to establish a continuous fifth GP lane and to address nonstandard design features (i.e. median width and sight distance on horizontal curves). The alternative would maintain the auxiliary lane configuration from the Orangewood Avenue interchange north to the Katella Avenue off-ramp.
    • Alternative 2B: Eliminate Orangewood Avenue On-Ramp, Widen Katella Avenue Off-Ramp (Widen 3 Bridges). Like Alternative 2, major construction under Alternative 2B would widen three bridges; the Orangewood Avenue UC Bridge (No. 55 0481), the Santa Ana River Bridge (No. 55 0400), and the Stadium OH Bridge (No. 55 0399). All other features noted under Alternative 2 related to the widening and restriping of the freeway to address nonstandard design issues would be the same under Alternative 2B

    Project costs (includes construction and capital R/W costs only) for the Build Alternatives have been estimated ranging from approximately $38 to $43 million for current cost and $49 to $55 million for escalated cost. Construction is anticipated to last 24 months; beginning in July 2023 and concluding in June 2025. After public circulation of the draft environmental document, all comments will be considered, and a preferred alternative will be selected and a final determination of the Project’s effect on the environment will be made. Alternatives considered but discarded included:

    • Alternative 2C - New Katella Avenue Off-Ramp, Retains Orangewood Avenue On-Ramp
    • Alternative 3 – New Stadium Bridge, Modified Auxiliary to Eastbound Orangewood Avenue On-ramp
    • Alternative 4 – New Stadium Bridge, Modified Auxiliary to Westbound Orangewood On-ramp
    • Project Transportation System Management (TSM) and Transportation Demand Management (TDM) Alternatives
    • Reversible Lanes

    In June 2019, the CTC approved for future consideration of funding a project located on Route 57 from Orangewood Avenue to Katella Avenue in Orange County (12-Ora-57, PM 11.5/12.5). The project proposes to construct a fifth general purpose lane in the northbound direction of Route 57 through the Katella Avenue interchange. Also proposed are upgrades to non-standard median and sight distances, and reconfiguration of existing on and off ramps which will relieve existing northbound Route 57 congestion and improve mobility by adding capacity. The project is currently funded through the Project Approval/Environmental Document phase from Surface Transportation Block Grant funds. Additional funding may potentially come from Federal, State and local sources. Construction is projected to begin in fiscal year 2022-23.

    Katella to Lincoln Avenue (~ ORA 12.532 to ORA 14.805)

    [Project Map]Improvements to this segment are planned through the 2007 Corridor Improvement Mobility Account allocations. Specifically, $70 million was approved to widen the route NB from Route 91 to Lambert Rd., and just over $20 million to widen the route NB from Katella Ave to Lincoln Ave. However, $36 million to add a NB lane from Lambert Rd. to L.A. Cty. line was not recommended.

    In July 2009, the CTC approved the transfer of deleted CMIA funding for Route 91 to Route 57 projects: specificially, they transferred $14,606,000 CMIA to the widen northbound Route 57 from 0.3 mile south of Katella Avenue to 0.3 mile north of Lincoln Avenue project (PPNO 3829), resulting in a total of $34,692,000 CMIA programmed on this project. The additional funds from CMIA will replace local Measure M funds programmed for construction.

    In February 2010, the CTC approved for future consideration of funding a project to construct additional northbound lanes and roadway improvements on a section of Route 57 in the city of Anaheim. (PPNO 3829) This project in Orange County will widen the northbound section of Route 57 between Katella Avenue and Lincoln Avenue in the city of Anaheim. The project is programmed in the Corridor Mobility Improvement Account and includes local measure funds. The total estimated project cost is $41,086,000 for 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. The Negative Environmental Impact Declaration (ND) indicates that the project will involve construction activities that may disturb potential cultural resource sites in the area or areas of contaminated soil.

    The construction contract was awarded for the Route 57 Northbound Widening – South of Katella Avenue to North of Lincoln Avenue project (PPNO 3829) in Orange County on October 26, 2011 with a cost savings of 10,565,000 (reflecting construction contract award savings), reducing the CMIA construction costs from $29,400,000 to $18,835,000.

    On December 22, 2014, the OCTA officially opened a new 3-mile northbound general-purpose lane between Katella and Lincoln Avenues in Anaheim. The $41 million project is the final segment of the Route 57 Northbound Widening Project, and improves a vital north-south link in Orange County.Additional capital and operational improvements include the reconstruction of eight freeway ramps, widening of two bridges, construction of six retaining walls, and the conversation from buffer-separated carpool lanes to continuous access carpool lanes, which studies have shown reduce accidents and air pollution.The northern segment of the SR-57 Northbound Widening Project opened to traffic earlier this year, adding a 5-mile northbound lane between Orangethorpe Avenue in Placentia and Lambert Road in Brea.

    Route 91 through Brea (~ORA 16.406 to ORA 20.87)

    [Brea Widening]In January 2009, the CTC approved for future consideration of funding a project to construct roadway improvements that include the construction of an additional northbound lane from Orangethorpe Avenue to Lambert Road (~ORA 16.406 to ORA 20.87) passing through the cities of Placentia, Fullerton and Brea. Specifically, the project will construct roadway improvements to a 5.0 mile long section of Route 57 in Orange County. The improvements will include the construction of an additional northbound lane. The project is programmed with corridor mobility improvement account (CMIA) funds and Orange County Measure “M” funds. The total estimated project cost is $140,000,000. It is estimated to begin construction in Fiscal Year 2009-10. The scope as described for the preferred alternative is consistent with the project scope set forth in the approved CMIA project baseline agreement.

    In July 2009, the CTC approved the transfer of deleted CMIA funding for Route 91 to Route 57 projects, specifically adding 54,548,000 CMIA to widen northbound Route 57 from 0.4 mile north of Route 91 to 0.1 mile north of Lambert Road project (PPNO 3788), resulting in a total of $124,548,000 CMIA programmed on this project. The additional CMIA funds will replace local Measure M funds programmed for construction. OCTA is also adding $2,751,000 in local funds for right of way support and capital cost increases due to the addition of 22 parcels needed for temporary construction easements. The additional right of way need was based on the preferred alternative selected during the environmental process.

    In August 2010, it was reported that a $102 million widening project was set to begin in late summer 2010. The project will add a five-mile northbound lane from Orangethorpe Avenue in Placentia to Lambert Road in Brea. It is expected to be completed in the summer of 2014. The project is funded by the extension of the countywide half-cent sales tax as well as by the Proposition 1B bond measure, both approved by voters in 2006. Another $41 million will be used to fund construction to add a three-mile northbound lane between Katella Avenue and Lincoln Avenue in Anaheim. That project will begin in summer 2011.

    In October 2012, it was reported that ramp closures and lane reductions are occuring as part of the widening northbound Route 57 as part of the addition of a northbound lane for three miles from Katella Avenue to Lincoln Avenue through Anaheim and a five-mile portion from Orangethorpe Avenue in Placentia to Lambert Road in Brea. Both projects, costing $147 million and funded by the state and county Measure M2 were halfway done as of October 2012, and are scheduled for completion in 2014. As of October, crews were paving the new northbound lane from Yorba Linda Boulevard to Lambert Road and continuing work to widen the overhead bridge at Placentia Avenue. Construction to widen the Nutwood Bridge is also under way. Fourteen bridges need widening along the freeway to accommodate the new northbound lane. The project also includes adding merging lanes and reconfiguring several on- and off-ramps.

    In January 2013, it was reported that work has begun on the Imperial Highway interchange with Route 57 (~ ORA R5.459) in conjunction with the above project. Work crews are excavating the area around the northbound Imperial Highway on-ramp to prepare for a temporary ramp that will be built. The temporary ramp will be used by motorists while crews reconstruct the permanent ramp. The on-ramps funnel traffic from the Brea Mall.

    Route 57 / Lambert Road Interchange Improvements (~ ORA 19.8/21.2)

    In May 2016, the CTC approved for future consideration of funding a project in Orange County that will construct roadway improvements on a portion of Route 57 (Lambert Road interchange, from roughly S of Birch Street to Tonner Canyon Road) in the city of Brea. The project is programmed in the 2014 State Transportation Improvement Program. The total estimated cost is $59,300,000 for capital and support. Construction is estimated to begin in Fiscal Year 2019-20. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2014 State Transportation Improvement Program. A copy of the MND has been provided to Commission staff. The project will result in less than significant impacts to the environment after mitigation. The following resource areas may be impacted by the project: biological resources, community impacts, visual/aesthetics, and paleontology. Avoidance and minimization measures will reduce any potential effects on the environment. These measures include, but are not limited to, transparent soundwalls will be installed to maintain view sheds, a Paleontological Monitoring Plan will be prepared prior to final design, and 1.5 acres of habitat replacement will be provided. As a result, an MND was completed for this project.

    In December 2017, the CTC received a STIP amendment proposal regarding the Route 57 / Lambert Road Interchange Improvements. The Route 57/Lambert Road Interchange Improvements project was originally planned for delivery in FY 2018-19. However, due to the lack of funding capacity available in the 2016 STIP, the project funding was significantly reduced. The City would now like to move forward with the Right of Way phase of this important regional project consistent with the original schedule. The Commission approved this project for future consideration of funding in November 2011 (Resolution E-16-25). The City plans to fund Construction in FY 2019-20 with potential sources such as local measure, Federal, State and Senate Bill 1 funding.

    The 2018 STIP, approved at the CTC March 2018 meeting, appears to move $9M in funding for this from FY19-20 to FY18-19, and rename the project PPNO 3834, Truck Climbing Lane Ph1, Lambert Rd IC imprvments. The project is described as in the City of Brea at the Route 57 & Lambert Road Interchange. Reconfiguration of northbound ramps including construction of a loop on-ramp at the south-east quadrant; realign southbound ramps and add fourth approach lane along the southbound off-ramp; widen south side of Lambert Road to provide dual exclusive eastbound right-turn lanes into the southbound on-ramp.

    The 2018 STIP also included an Advance Program Development Element (ADPE) allocation of 4.05M for Phase 2 of the project (PPNO 3847A), from Lambert Road to the County Line. This funding is for environmental and planning in FY20-21.

    In October 2018, the CTC approved an allocation of $74,705,000 for the State-Administered multi-funded Senate Bill 1 (SB 1) Trade Corridor Enhancement Program (TCEP)/State Transportation Improvement Program (STIP) Route 57 Lambert Road Interchange Improvements project (PPNO 3834), in Orange County, on the State Highway System.
    (Source: October 2018 CTC Agenda Item 2.5s.(7))

    At the end of December 2018, it was reported that one of the projects planned in Orange County in 2019 was on Route 57 at Lambert Road in Brea, where the ramps will be reconfigured and modified. About a half mile of auxiliary lanes will be added to southbound Route 57, and the northbound Lambert Road bridge will be widened. Period: July 2019 – July 2021. Cost: $107.4 million.
    (Source: OC Register, 12/31/2018)

    In March 2020, the CTC approved the 2020 STIP, which appeared to continue the previously programmed funding for PPNO 3834 "Truck Climbing Lane Ph1, Lambert Rd IC imprvments(TCEP)". However, the STIP did appear to delete the programmed funding for PPNO 3847A "Truck Climbing Lane Ph2, Lambert Rd-Co. Line (APDE)".
    (Source: March 2020 CTC Agenda, Item 4.7, 2020 STIP Adopted 3/25/2020)

    In August 2019, the CTC approved the following allocation: $94,003,000. 07-LA-57 R0.0/R4.5. Route 57 In and near Diamond Bar, from the Orange County line to Route 60. Outcome/Output: Rehabilitate roadway by replacing the full structural section on the inner lanes, replacing individual slabs on the outer lanes and the High Occupancy Vehicle (HOV) lanes, upgrading the concrete median barrier, and grinding and placing pavement on ramps.

    Route 57/Route 60 Interchange

    In November 2010, it was reported that there is a project to improve the Route 57/Route 60 interchange (~ LA R4.462L to LA R4.603). The "57/60 Confluence Project" has the goal of solving the problem of 16 lanes of traffic being squeezed into 12. The improvements include creating a bypass lane to reduce the need for motorists to cross several traffic lanes as they exit or enter the freeway at Grand Avenue. The project also calls for construction of an eastbound bypass ramp, which would run under Route 57 and take traffic exiting Route 60 directly to Grand. A new eastbound loop on-ramp would connect Grand to Route 60 and eliminate the need for left turn lanes. The existing westbound off-ramp at Grand would be widened and relocated about 100 feet north. Plans also include construction of a new 2,500-foot auxiliary lane on southbound Route 57 as it merges with Route 60. The third lane would eliminate the bottleneck that is currently created when the southbound Route 57 drops from three lanes to two. The Grand overpass would be raised and widened to accommodate four lanes in each direction. It also would feature a new westbound on-ramp. The project would create 5,148 jobs, with targeted completion in less than 10 years. The interchange has been designated as the No. 1 highway congestion segment in Caltrans' District 7, and the No. 3 congestion segment in the state, according to the Caltrans Highway Congestion Monitoring Program. It is also in the Metropolitan Transportation Authority's Long Range Transportation Plan, but the funds will not be available until 2029. The current goal is to complete the project by 2016. More than half of the project's $258 million price tag is eligible for federal funding, while the remainder would be funded with local sales tax and state gas tax revenues. Currently, the city of Industry has committed $35 million in local redevelopment funding to the project. MTA's contribution would be an additional $8.75 million for the construction of the westbound off-ramp at Grand. Together with MTA and Diamond Bar, the city of Industry also is seeking project funding and potential listing on the next federal reauthorization of the Transportation Act.

    In May 2013, the CTC received notice of the preparation of an EIR concerning the Route 57/Route 60 interchange. The project is proposed to be funded with federal and local dollars. Depending on the alternative selected, the total estimated project cost is between $220,000,000 and $239,000,000. Construction is estimated to begin in Fiscal Year 2015-16. The alternatives under consideration are: (1) No Build Alternative; (2) maintains the existing compact-diamond configuration with added capacity at on and off-ramps, adding a new bypass single ramp lane would connect from northbound Route 57 to the Grand Avenue off-ramp, and a bypass lane on-ramp would be constructed to connect Grand Avenue to eastbound Route 60. In the westbound direction of Route 60, the existing dropped lane would be extended all the way to Grand Avenue. The Grand Avenue overcrossing would be widened to four lanes in each direction. (3) This builds on the previous alternative, except an additional eastbound loop on-ramp from Grand Avenue is proposed as a component of the project.

    In March 2014, the CTC approved for future consideration of funding a project in Los Angeles County that will reconfigure the conflux of Route 60 and Route 57 at Grand Avenue, including widening the Grand Avenue overcrossing, adding auxiliary lanes, and reconfiguring the on- and off-ramps. The project is not fully funded. The project is fully funded for environmental only with federal and local dollars. The total estimated cost is $231,000,000 for capital and support. Depending on the availability of funding, construction is estimated to begin in Fiscal Year 2014-15.

    In September 2014, it was reported that Federal officials approved a $10-million grant for a series of fixes to the congested interchange between Route 60 and Route 57 in eastern Los Angeles County. The $10-million grant from the U.S. Department of Transportation will partially fund on- and off-ramps to eastbound Route 60. The first stage of construction is expected to cost about $53 million and will probably start in summer 2015. For two perilous miles in Diamond Bar, Route 60 and Route 57 combine, reducing 17 lanes to 14, while more traffic merges on and off from a local intersection. Cars and trucks frequently veer across up to five lanes to reach the correct exit. Intersecting freeways are typically built at 90-degree angles. But in the early 1970s, engineers built Route 57 alongside Rolute 60 because the curve of the hillside was too steep to accomodate another configuration. The goal of the construction is to separate the movements.

    In November 2015, it was noted that the 2014 TIGER grant is going toward the $260 million total cost of the Route 57/Route 60 interchange project, expected in three phases. November 2015 marked the kickoff of construction of phases one and two. The complete project includes ramp and interchange reconfigurations and the addition of mainline and bypass lanes to reduce weaving. The $10 million TIGER grant will be used specifically for construction of a westbound freeway off-ramp at Grand Avenue in the project’s second phase. But, while phases one and two are moving forward, funding for the third and largest phase of the 57/60 Confluence Project has yet to be identified. Considered the bulk of the project —with the mainline improvements and bypass roads on Route 57 and Route 60 to eliminate the weaving— it currently has secured zero funding and is an unfortunate reminder of the great need for funding throughout the country where projects are not moving forward.

    In March 2016, the Los Angeles MTA presented its full proposal for what transit lines could be built -- and when -- if Los Angeles County voters approve a half-cent sales tax increase in November 2016. This proposal included funding for Route 57/Route 60 Interchange Improvements that include adding a new westbound on-ramp to Route 60 at Grand Ave., street widening improvements in the vicinity of Grand Ave. and Golden Springs Dr., a new westbound off-ramp to Route 60 and auxiliary lane to Grand Ave., freeway mainline improvements and by-pass connectors, for a total of 2 miles.

    Commuter Lanes Commuter Lanes

    Commuter lanes exist between Route 5 and the junction with Route 60 in Los Angeles County. These lanes in Orange County opened in June 1992; the lanes in Los Angeles County opened in November 1997. There is also a HOV interchange with Route 91 that is primary commute directions only: SB Route 57 to WB Route 91, and EB Route 91 to NB Route 57. In February 2007, the HOV transition from NB Route 57 to EB Route 60, and WB Route 60 to SB Route 57 opened after three years of disruptive construction.

    Naming Naming

    This segment is named the "Orange Freeway". It was named by Assembly Concurrent Resolution No. 17, Chapter 157, in 1969. The first segment opened in 1969; the last segment in 1976.

    Officer Donald J BurtThe segment between Orangethorpe Avenue and Yorba Linda Boulevard in Orange County (~ ORA 16.403 to ORA 18.369) is named the "CHP Officer Don J. Burt Memorial Highway.". California Highway Patrol Officer Don J. Burt, a dedicated officer, was killed while in the line of duty on the evening of July 13, 1996, when he was fatally shot by a suspect during a traffic stop on State Highway Route 57. Officer Burt is remembered as a dedicated officer with an infectious sense of humor that endeared him to friends, colleagues, and his supervisors. He was only 25 years old at the time of his death, and left behind a wife, son, and his parents. He came from a line of law enforcement officers, including his father, father-in-law, and brother-in-law. An estimated 4,500 police officers and other mourners, including officers from Maryland and New Jersey, attended his funeral, including then Governor Pete Wilson. The highway was named to remind us of the sacrifices California Highway Patrol and other peace officers make on a daily basis. Named by Assembly Concurrent Resolution 7, Chaptered 7/2/2003, Chapter 80.

    The portion of Route 57 from the Orange County Line to the Pathfinder Road exit in the City of Diamond Bar (LA 0.000 to LA R2.986) is named the “Mayor Bob Zirbes Memorial Freeway”. This segment was named in memory of Robert "Bob" Zirbes, an immensely respected member of the Diamond Bar City Council. Bob served as Chairman of the Diamond Bar Planning Commission for a year prior to being elected to the Diamond Bar City Council in 2001, and was reelected to a second term in 2005 and distinguished himself as Mayor from 2003 to 2004. Throughout his years on the city council, Bob worked diligently to address the concerns and needs of the residents of the area and improve the quality of life for future generations. Through his dedication and perseverance, the City of Diamond Bar redefined its Code Enforcement Program and created a proactive approach to property regulations enforcement, known as the Neighborhood Improvement Program. Bob was the driving force behind the creation of the Home Improvement Program to financially assist homeowners with home repairs. He also worked tirelessly behind the scenes to promote economic growth for the City of Diamond Bar, which includes the newly completed Village Center, highlighted by the recent opening of a Target store and the new Brookfield residential community. Prior to his election to the city council, Bob served as President of the Diamond Bar Improvement Association, a nonprofit community betterment organization, where he spearheaded several community service-based efforts, including the annual Paint the Town project. Bob was also a member of several boards and committees, including the City's Sports Park Task Force, Library Task Force, Tres Hermanos Conservation Authority, Walnut Valley Rotary Club, and Miss Diamond Bar Pageant, and was also very involved in the American Youth Soccer Organization program, where he was a referee even when his own children had long outgrown the program. Named by Assembly Concurrent Resolution (ACR) 82, Resolution Chapter 78, on 7/8/2008.

    Officer Louie PompeiThe interchange with I-210 (i.e., the former Route 30/Route 210 interchange) (~ LA R11.602R) is named the "Police Officer Louie Pompei Memorial Interchange". Louis ("Louie") A. Pompei was born August 4, 1964, in Shenandoah, Pennsylvania. He was a physical fitness buff, and body builder, who earned a silver medal in the bodybuilding competition of the 1994 California Police Olympics, and who was a runner on the Glendora-Monrovia-Arcadia Police relay team, which annually competes in the Baker to Vegas 120-mile Challenge Cup relay race. He graduated from Mansfield University, Pennsylvania, in 1986 with a BA degree in Criminal Justice Administration; and was hired as a Police Officer trainee by the Glendora Police Department on October 12, 1987. He graduated from the Los Angeles County Sheriff's Academy on March 4, 1988, and worked in the Patrol Division of the Glendora Police Department from 1988 to 1992 where he developed an enthusiasm for working narcotics cases, working as a narcotics investigator in the Detective Division of the Glendora Police Department from 1992 to 1995. During this time, he was assigned to a position with L.A. IMPACT, a major crimes multijurisdictional task force, composed of officers from agencies throughout the county, primarily dedicated to investigating major drug suppliers through southern California. On June 9, 2002, while off duty in a Vons Market in Via Verde, Officer Pompei attempted to stop an armed robbery takeover in which a box boy was being pistol whipped, and was killed in a fire fight. His colleagues remember him for his love of life, contagious enthusiasm, positive and outgoing attitude, and generous, helpful, and dependable personality. Named by Senate Concurrent Resolution 64, Chapter 105, on August 8, 2002. Surprisingly, the resolution refers to the Route 30/Route 210 interchange, even thought at the time of passage, Route 30 no longer existed. I guess the legislative analyst missed finding that error.

Statistics Statistics

Overall statistics for Route 57:

Pre-1964 Legislative Route Pre-1964 Legislative Route

The route that eventually became LRN 57 was first defined in 1915 by Chapter 748, which authorized survey, location, and estimate of cost of a state highway "from a point on the present located state highway in Kern County S of Bakersfield to the town of Nordhoff, Ventura County" (Nordhoff appears to have been a former name for Ojai). The 1919 Third Bond Act authorized a route from Santa Maria to Freemans via Bakersfield. In 1935, the route was codified as:

"[LRN 2] near Santa Maria to [LRN 23] near Freeman via Bakersfield and Walker Pass"

This routing remained unchanged until the 1963 renumbering. It was signed as follows:

  1. Between US 101 (LRN 2) and 7 mi NW of Ventucopa, it was signed as Route 166.
  2. Between 7 mi NW of Ventucopa and Maricopa, it was cosigned as Route 33/Route 166.
  3. Between Maricopa and 6 mi N of Wheeler Ridge, the route was originally cosigned as Route 33/Route 166, and is present-day Route 166 (the Route 33 designation having been removed when US 399 was decommissioned)
  4. The route appears to have been discontiguous between 6 mi N of Wheeler Ridge and Bakersfield.
  5. Between Bakersfield and US 6 (LRN 23), the route was signed as Route 178 (no change post-1964).
