Project Fact Sheet

Project Description:
The State Route 132 (SR-132) West Freeway/Expressway Project (SR-132 West) proposes to construct a four-lane freeway/expressway on a new alignment in Stanislaus County and in the City of Modesto from SR-99 just south of Kansas Avenue west to near Dakota Avenue.  This project is approximately four miles in length and would be planned for an ultimate multi-lane freeway.  The project would replace the existing segment of SR-132 along Maze Boulevard from near SR-99 to near Dakota Avenue.  SR-132 West improvements include providing freeway to freeway branch connections from and to SR-99 and a portion of the ultimate freeway corridor west of SR-99, as well as proposed direct connection from SR-132 to Needham Avenue overhead connecting to downtown Modesto.  The connection requires a new public road connection approval by the California Transportation Commission.  Furthermore, connections from and to 5th Street and 6th Street, one-way roadways, are proposed as part of the SR-132 West Project.

Purpose and Need:
The primary intent of the SR-132 West Project is to improve regional and interregional circulation, provide congestion relief, enhance safety and improve operations.

SR-132 serves as a major access route for an increasing number of central valley commuters traveling to work in and around Modesto as well as a major truck route.  Motorists are experiencing a high level of congestion due to the limitations of the existing facilities, as well as an increase in interregional commuter and truck traffic.  Also, the connectivity of SR-99 and SR-132 requires travel through residential and commercial areas of Modesto.  Additionally, uncontrolled access to schools, churches, businesses, and residences along this roadway add to the slow moving traffic and increase the potential for conflicts between bikes, pedestrians, and vehicles.  SR-132 within the project limits exhibits accident rates higher than the statewide average for similar highways.

Since the 1950’s the State recognized the need to relocate SR-132 to a new corridor that would allow the construction of a freeway facility.  In 1956, the proposed freeway corridor for SR-132 was adopted by the State with resolutions of support from the County of Stanislaus and the City of Modesto.  In 1958, the State allocated funds for right of way and proceeded with the acquisition of all but a few parcels.  Repeated efforts since 1958 were stalled due to a lack of available funds.  Caltrans in conjunction with Local agencies prepared three Project Study Reports (PSR) (in 1991, 1993, and 1997) to determine alternatives for consideration of evaluation.  From 1998 to 2003 efforts were made to achieve consensus on a buildable alternative and progressed to a Value Analysis  Study.  Later in 2003, the project was placed on hold after it was determined that there was a need to complete additional system traffic planning studies to resolve the SR-132 West and SR-132 East connectivity concerns.  In 2008, Stanislaus Council of Governments (StanCOG) completed the Feasibility Study for the SR-132 East / West Connectivity Project in which various SR-132 improvements are identified to improve east-west connectivity in Modesto, which included several components of prior studies and evaluations.  Thus, the SR-132 West Project is the evaluation for the segment of roadway from near the SR-99/SR-132 connection to west of the City of Modesto limits.  In 2009, StanCOG completed a local Project Initiation Document which established the project scope for use in planning the next formal studies for the Project Approval and Environmental Document (PA&ED) Phase.

Funding Source:
StanCOG is the lead agency implementing this project.  Caltrans is CEQA lead agency.  The anticipated cost of the project ($140-$170 million) requires project funding to come from a combination of federal, state, and local, funds.  Due to funding constraints the project construction is expected to be completed in phases, which have yet to be determined.  At this time approximately $31.4 million has been programmed for the project.
