County Transportation Agencies

County Transportation Agencies, or CTAs, are county-level organizations responsible for preparing and implementing congestion management programs.

Eight Bay Area counties are among the 20 counties statewide whose voters have approved dedicated transportation sales tax measures.

They are home to more than 80 percent of all Californians. Your voter-approved measures finance local street and road, highway, transit, freight, bicycle and pedestrian projects.

CTAs administer the One Bay Area Grant Program launched by MTC to link the region’s federal transportation money with California’s greenhouse gas emission reduction requirements.
