Local Service

Welcome to Tri Delta Transit!

Serving the cities of Antioch, Pittsburg, Brentwood, Oakley and Bay Point (with limited service in Concord and Martinez), we operate 15 local bus routes Monday-Friday (including route 300) and five on weekends & holidays. 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.
