State Route 132 West
The purpose of the project is to improve regional and interregional circulation, relieve traffic congestion along existing State Route132 (SR-132)/Maze Boulevard, and improve operations by creating a four-lane freeway/expressway on a new alignment connecting SR-132 with the City of Modesto.
The project would be built in two phases. It would begin at the intersection of existing SR-132/Maze Boulevard and North Dakota Avenue, and extend north along North Dakota Avenue for roughly a half mile. South of Kansas Avenue, at the proposed intersection with North Dakota Avenue, the new alignment would extend east to State Route 99 (SR-99) at the proposed Needham Street overcrossing. The project would also make improvements to the 5th Street and 6th Street connections to SR-99 including restriping and the reduction of conflict points between SR-99 and 5th and 6th Streets.
The existing route is a flat, rural two-lane undivided conventional highway with shoulders and isolated left turn and right turn lanes. It passes through residential, commercial and agricultural areas with posted speeds ranging between 25 mph and 50 mph. The proximity to schools, churches, businesses, and residences along Maze Boulevard make for slow-moving traffic, congestion during peak hours, potential conflicts with pedestrians and bikes, and a non-compatible truck route. The upgraded route will result in more efficient travel in the area.
Project funding comes from local, state and federal sources. The construction cost estimate for Phase 1 is approximately $82 million. The construction cost estimate for Phase 2 is approximately $132 million. The total project cost is estimated at up to $214 million. Escalated capital outlay support costs are estimated at approximately $43 million. This would be in addition to the construction cost of $214 million.

This is a collaborative effort managed by the Stanislaus Council of Governments (StanCOG). Because this is a State highway, Caltrans serves as the lead agency under the California Environmental Quality Act and National Environmental Policy Act. Caltrans and StanCOG are working in cooperation with the City of Modesto, Stanislaus County and the California Department of Toxic Substances Control.
