Bus Bridge and Red Line Cancellation Alert: Free buses replace trains between Rockridge, MacArthur, and 19th Street stations on six weekends this year (first work weekend 6/22-6/23)
On the weekend of June 22-23, BART crews will begin the process of replacing a series of interlockings between the Rockridge, MacArthur, and 19th Street stations. Interlockings are a vital part of the BART system. They are segments of the railway that allow trains to safely move from line to line. To ensure a safe workspace for the project team, free buses will replace trains between the three stations. Riders can expect delays of up to 40 minutes on work weekends. Work will take place through the heart of the District on select, non-consecutive weekends into 2026
Free buses will replace trains between Rockridge, MacArthur, and 19th Street stations on the following weekends: June 22-23; July 20-21; August 17-18; September 21-22; October 19-20; and November 2-3. In addition to the track shutdown there will be no Red Line service on these weekends.
Key service impacts on all work weekends for this project include:
*Red Line service cancelled (service to/from Millbrae will be via the Yellow line).
*MacArthur Station will be open for southbound Orange Line stops from Richmond. No Yellow Line service to MacArthur.
*Orange Line bus bridge will operate between MacArthur and 19th St.
*Yellow Line bus bridge will include buses that go directly between Rockridge and 19th St as well as buses that also stop at MacArthur. Extra BART personnel will guide riders to the free buses.
*Lower level platforms at both 12th and 19th Street stations will be out of service.
*Yellow Line 20-minute service
*Orange/Blue/Green Lines 30-minute service
*All buses used for the bus bridge will be outfitted with racks for bicycles. Please avoid bringing motorized bikes or eBikes to the bus bridge as they may not be allowed on the buses.
*All train schedules will be different from the normal weekend timetables. Please check the Trip Planner to see the new train departure times.
*Due to the new schedule, the last train departures of the night may be earlier than the regularly scheduled departures.
BART crews will make the most of their time in the system by taking on as many trackway improvement projects as possible on the weekends when this portion of the system is closed to trains. In addition to replacing interlockings, the team will also replace traction power cables, install new train control equipment, install new digital display signs at underground stations up to Berkeley and 12th Street/Oakland City Center, manage vegetation that could impact service, and do deep station cleaning.
This will be one of the most challenging rebuilding projects that BART has ever undertaken because of the location of the project. With limited workspace, crews will be unable to use a crane or other heavy equipment to lift track components into place. Instead, workers will transport all materials on rail and assemble larger components by hand. The equipment being replaced is decades old and has outlived its design life. Riders will enjoy a smoother, safer, more reliable, and quieter ride once this project is complete.
This project is part of BART’s overall effort to improve the 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.
