New TDT Network launches Sunday, August 10, 2025 – Major Service Change

July 8, 2025

Tri Delta Transit is excited to launch the New TDT Network that was created based on feedback from the public and ridership data as part of the year-long project Revitalize Tri Delta Transit.
Routes will be changed to be more efficient, come faster and get you where you want to go. Tri MyRide zone has expanded in Antioch/Oakley, is still a large zone in Pittsburg/Bay Point and will now be provided as a service in Brentwood. Route numbers will also change. New TDT Network information can be found at www.revitalizetridelta.com.

We can’t wait to bring you a better, brighter system.
