I-80 East CSMP is now available

Connecting the Bay Area with the Sacramento Region

The Interstate 80 East Corridor operates as an east/west route starting at the Contra Costa/ Solano County line (Carquinez Strait) and ends at SR-113 North. The corridor is approximately 43 miles in length and crosses SR-29, SR-37, SR-12, SR-113, I-505, I-680, and I-780.

Interstate 80 East is part of the Interregional Route System (IRRS) and is classified as a High Emphasis Route connecting the Bay Area with the Sacramento region. The District 4 segment of the Interstate 80 East Corridor is classified as freeway, including the segment that spans the Carquinez Strait. The Carquinez Strait is considered a regional gateway contributing to the national significance of the corridor. 

This Interstate, as one of the two such facilities that extend east of the Bay Area, is vital to interregional and regional commuting, freight movement and recreational travel.

Corridor Specific Issues

  • I-80 East provides seamless access to major interregional and regional goods movement corridors including I-5, SR-99, US-101 and I-880.
  • I-80 East is a major commuter link between SF/East Bay employment centers and Solano County housing. 

Corridor Mobility Improvement Account (CMIA) Project

The CSMP requirement is noted in the Baseline Agreements of all projects receiving CMIA funding. CMIA funds have been allocated for the following improvement project on the I-80 East Corridor:

  • HOV Lanes, Red Top Road to Air Base Parkway
