About Tri Delta Transit

Serving the cities of Antioch, Pittsburg, Brentwood, Oakley, Bay Point, Discovery Bay and Concord, we operate local bus routes, an express bus route to BART, and luxury motorcoach service to all 49er home games. Every day we help East Contra Costa residents get to BART, work, school, the doctor, the library, parks, the movies, shopping centers, the grocery store, recreation activities, or just across town to visit family & friends. We also connect with County Connection bus service, WestCAT bus service, Delta Breeze bus service and Amtrak at shared bus stops.
