In partnership with other public agencies, transit operators, and local jurisdictions, we plan, fund, and deliver the transportation projects and programs that keep Contra Costa moving. Our work touches every corner of the county and every resident – whether through investment in new roadways or planning safe routs to school. We encourage you to explore the results of your investment in transportation in Contra Costa County through this site.
