What We Do


The Contra Costa Transportation Authority (CCTA) is a public agency formed by Contra Costa voters in 1988 to manage the county's transportation sales tax program and to do countywide transportation planning.

CCTA is responsible for maintaining and improving the county’s transportation system by planning, funding, and delivering critical transportation infrastructure projects and programs that connect our communities, foster a strong economy, increase sustainability, and safely and efficiently get people where they need to go. CCTA is also the county's designated Congestion Management Agency (CMA), responsible for putting programs in place to keep traffic levels manageable.

We work to improve our quality of life and help make our community great – now and in the future.


Mission Statement

CCTA's mission is to deliver a comprehensive transportation system that enhances mobility and accessibility, while promoting a healthy environment and strong economy by:

  • Leading a collaborative decision-making process with local, regional and state agencies;
  • Establishing partnerships to effectively deliver transportation projects and programs;
  • Facilitating a countywide dialog on growth and congestion that discloses and seeks to mitigate the impacts of development while respecting the responsibilities of local jurisdictions;
  • Taking into account the diverse character of Contra Costa communities.
