U.S. Highway 50 Multimodal Corridor Enhancement and Rehabilitation Project

Project Facts


This comprehensive corridor project will construct High Occupancy Vehicle (HOV) lanes and rehabilitate pavement on US 50 from the US 50/I-5 Interchange (PM L0.6) to the US 50/Watt Avenue Interchange (PM R5.3).

Project Benefits

The purpose of this project is to replace the existing Portland Cement Concrete (PCC) pavement, reduce maintenance crew’s exposure to live traffic, and reduce maintenance expenditures. The project scope also includes the restoration of other roadway elements such as drainage, lighting, and pedestrian facilities. The existing PCC pavement was built between 1967 and 1971 and has reached the end of its service life. It is deteriorated and has a poor ride quality that requires annual maintenance to repair and maintain. A recent pavement condition survey conveyed that there is severe slab cracking and faulting in the no. 3 and 4 lanes in both directions and minor slab cracking in the no.1 and 2 lanes in both directions. This project will also increase the deficient vertical clearance at seven over crossing structures in the project limits as identified in the District 3 Goods and Movement Study. This increased vertical clearance will reduce the frequency of “high load” hits, reduce maintenance worker exposure to traffic, and improve freight mobility in this corridor.

The project also proposes to:
-Allow connectivity and consistency with the planned HOV system in the Sacramento Region.
-Enhance mobility and provide incentives for ride sharing during peak period travel
-Achieve the goals of the current SACOG MTP by promoting ride sharing.
-Improve US 50 to meet the growing travel demand in the Sacramento Region.
-Provide an option for reliable peak period travel time. -Use the highway facilities as efficiently as possible. -Improve general traffic operations by reducing congestion and travel time. -Improve bicycle and pedestrian access. 


• SHOPP Roadway Rehabilitation program. The total project cost for the long life pavement replacement, other highway asset upgrades and improving the vertical clearance at seven overcrossings is estimated at $365.2 million.

• Sacramento Measure A Transportation Sales Tax Program managed by Sacramento Transportation Authority (STA) for $28.4 million for the preliminary engineering, environmental studies (PA&ED), design, right-of-way work and construction.

• Solutions for Congested Corridors Program (SCCP) by State of California’s Senate Bill(SB) 1 - Road Repair and Accountability Act of 2017 for $90 million for construction.
