Schedule note: The times published in Tri Delta Transit’s timetables in printed schedule and on this website are approximations of normal trips. They do not anticipate service disruptions, traffic, delays of boarding and off-boarding, or other possible disruptions.

Tri Delta Transit is excited to announce our STUDENT COVER ART CONTEST to design our January 11, 2026 printed schedule cover. 2026 is our 50th year of serving eastern Contra Costa County so we wanted to include the people we serve. The contest is open to students from elementary to community college.
