Bus Bridge Alert: free buses replace trains between Walnut Creek and Concord June 21-22

BART must replace decades old track components between Walnut Creek and Concord stations to ensure reliable service. To allow for the work to happen in the most efficient way possible as well as to provide safe conditions for workers, there will be no train service between Walnut Creek and Concord on Saturday June 21 and Sunday June 22. Instead, riders will get off their train and take a free bus to move between Walnut Creek, Pleasant Hill/Contra Costa Centre, and Concord stations. Riders can expect delays of 20 to 30 minutes in the work area.

The project will also require the cancellation of some late night and early morning trains.

Saturday Morning:

• The first southbound trains departing Concord at 5:35am and 5:55am will be cancelled.
• Instead, the first southbound trains going to San Francisco will depart Walnut Creek at 5:43am, 6:03am, and 6:23am.
• To accommodate southbound passengers, buses will depart Concord at 5:23am, 5:43am, and 6:03am and Pleasant Hill at 5:30am, 5:50am, and 6:10am to connect with these trains.

Saturday and Sunday Night:

• The last southbound train departing Antioch at 11:42pm and Pittsburg/Bay Point at 12:10am will be cancelled.
• Riders must take the earlier southbound train, which departs Antioch at 11:32pm and Pittsburg/Bay Point at 11:44pm.

Sunday Morning:

• The first southbound trains departing Concord at 7:35am and 7:55am will be cancelled.
• Instead, the first southbound trains going to San Francisco will depart Walnut Creek Station at 7:43am, 8:03am, and 8:23am.
• Buses will depart Concord at 7:23am, 7:43am, and 8:03am and Pleasant Hill at 7:30am, 7:50am, and 8:10am to connect with these trains.

This upcoming work is part of BART's overall effort to improve safety and reliability of the 131-mile, 50 station system. There are now more rebuilding projects happening across BART than at any point in its 50-year history.
