Local Service

Welcome to Tri Delta Transit!

Serving the cities of Antioch, Pittsburg, Brentwood, Oakley, Bay Point, Discovery Bay and Concord, we operate 14 local bus routes Monday-Friday (including express route 300) and three 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.

Getting Started

Getting started is easy. To figure out which route you need, scroll through the attached system map. Routes are color coded to help you locate individual routes serving your location. Once you know which route(s) you need, click the above link called “Schedules and Maps” to see your selected route(s) including bus arrival times.

If you need assistance reading the schedule, click here to read our “How to Ride the Bus” page. Or, give us a call at 925-754-4040 and we’ll be happy to assist you.

Local Bus Stops

There are over 650 bus stops served by Tri Delta Transit local buses. Every bus stop served by each route is listed along with maps and schedules on this web site. To see a list of bus stops served by any route, simply select that route from the “Schedules & Maps” pull down menu above. For example: click here to view Route 380 Eastbound and you will see the Bus Stop List button to all bus stops served by the 380 Eastbound bus. Bus stop locations are identified by city, street, cross street and a landmark if available. To help make sure you arrive at the correct bus stop, each bus stop sign lists the route, and direction of travel.
