Transportation Plan


Final 2017 Countywide Transportation Plan (CTP) Adopted by CCTA on September 20, 2017. 

The CTP provides the overall direction for achieving and maintaining a balanced and functional transportation system within Contra Costa County while strengthening links between land use decisions and transportation. It outlines the Contra Costa Transportation Authority’s vision for Contra Costa and establishes goals, strategies, projects, and actions for achieving that vision.

On September 20, 2017 the Authority adopted the Final 2017 CTP Update. The 2017 CTP comprises two volumes:

  • Volume 1 provides the Vision, Goals, and Strategies; a review of issues facing our transportation system; an overview of the cooperative planning process in Contra Costa; and an implementation plan for meeting our transportation goals.
  • Volume 2 contains a summary of the Action Plans, along with a performance and equity evaluation of major projects, those costing more than $25 million. 

These documents, along with the Draft Environmental Impact Report can be downloaded below and more information on both items can be found at and CTP EIR page.
