Bay Area voters approved a bridge toll increase for regional transportation improvements in 1988 and 2004. Solano County has constructed the following projects with the funds from these bridge tolls:


  • Carquinez Bridge (2003) and Benicia-Martinez Bridge Replacement (2007)


$184 Million funded:

  • 2 Rail Projects
  • 4 Capital Road and Freight projects
  • 5 Intermodal Transit Stations
  • SolanoExpress Operating Funds (27% from RM 2)
  • SF Bay Ferry Operating Funds for Vallejo service


A majority of voters in Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano and Sonoma counties approved RM3 on June 5, 2018. The toll revenues will be used to finance a $4.45 billion slate of highway and transit improvements in the toll bridge corridors and their approach routes. RM3 raises tolls on the region's state-owned toll bridges by $1 beginning Jan. 1, 2019. Tolls will rise by another $1 in January 2022, with another $1 increase in January 2025. This marks the first toll increase on the seven state-owned bridges since 2010. Two of the seven Bay Area bridges are located in Solano County.

More information on RM 3 can be found on the Metropolitan Transportation Commission website:
