511 Contra Costa
511 Contra Costa is a county-wide program that strives to reduce traffic congestion and improve air quality by providing the public with information, resources, and tools that promote mobility options beyond driving alone.
Explore New Ways to Commute
511 Contra Costa can help you plan a bike route, find the best public transit service to get you where you need to go, explore rideshare options, and more.
We help employers make worksites bike and carpool friendly and can assist with commuter benefit programs. We also support work from home, micromobility, the switch to electric vehicles, and other emerging mobility trends that reduce CO2 emissions.
Our Commuter and Employer Newsletters keep residents and workers up to date on the latest transportation news and incentive offers.
Funding, Sponsorship, and Oversight
Funding for 511 Contra Costa programs is provided primarily by the Bay Area Air Quality Management District’s Transportation Fund for Clean Air and the local half-cent sales tax, known as Measure J, approved by voters in in 2004 and administered by the Contra Costa Transportation Authority (CCTA).
511 Contra Costa serves all 20 jurisdictions of the county. Sponsorship and program oversight is provided by the four regional transportation planning committees: SWAT, TRANSPAC, TRANSPLAN, and WCCTAC; and CCTA.
