On Wednesday, September 20, 2017, the Authority Board voted to adopt the Final Countywide Transportation Plan.

Countywide Transportation Plan 2017 Update


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

Achieving the Plan’s Goals

CCTA Planning Transportation funds infographicThe 2017 Countywide Transportation Plan will play an important role in shaping our transportation policy and investment decisions. Currently about $3.7 billion in project funding has been identified, which is not enough to meet Countywide transportation needs over the next 23 years. The Plan outlines the strategies that will be essential for a smooth transition from vision to reality.

The Authority will need to work with many public and private sector partners to leverage the funds needed to achieve the CTP goals to:
