Ride 4 Free: Tri Delta Transit 20-Ride Pass Offer

We have run out of free passes.

Riding transit helps to reduce traffic congestion and greenhouse gas emissions, and we appreciate your interest in taking the bus.

You can still get a great deal with our Buy One Get One Free pass program. Buy the first 20-Ride Tri Delta Transit pass and get a second, free pass, compliments of 511 Contra Costa.

Ride 4 Free passes made available with funding from Contra Costa Transportation Authority and the Bay Area Air Quality Management District.
