Several overlapping construction jobs and a large downtown convention will change how people move through San Francisco from Thursday, Nov. 12, through Wednesday, Nov. 18, according to the SFMTA's weekly transit and traffic advisory. The biggest transit change is a weekend BART shutdown in the Mission and on the Daly City line. Drivers heading to Moscone Center face a multi-day street closure on Howard Street.

BART: no trains from 24th Street Mission to Daly City this weekend

On Saturday, Nov. 14, and Sunday, Nov. 15, there will be no BART train service between 24th Street Mission and Daly City while crews install equipment for a new communications-based train-control system, BART said. The entire Green Line will not run. Glen Park and Balboa Park will have no trains; free buses will replace service in the closed segment.

SamTrans will run express buses between 24th Street Mission and Daly City with no intermediate stops. Muni will run a local "hopper" bus between those stations with stops at Glen Park and Balboa Park. The buses will have front-mounted exterior bicycle racks, BART said. The Red Line will run only as far as 24th Street Mission from Richmond, and the Blue Line will run from Dublin to 24th Street Mission. Train service between Daly City and Millbrae will run every 15 minutes. Other lines are scheduled for 20-minute service, though departure times may shift by up to three minutes because trains will turn around at 24th Street Mission. An extra Orange Line train will leave Berryessa at 5:40 a.m. Saturday and 7:40 a.m. Sunday to replace a canceled Green Line trip, BART said. Allow extra time, especially for SFO and Peninsula connections that normally use the closed segment. A Bay Area Brief guide published earlier has the full bus-bridge plan.

Downtown streets: Microsoft Ignite closes Howard Street

Howard Street between 3rd and 4th streets will be closed from 6 a.m. Thursday, Nov. 12, through 6 p.m. Sunday, Nov. 22, for Microsoft Ignite 2026, the SFMTA said. Additional lane closures are planned around Moscone Center. From Thursday through Nov. 22, Howard Street traffic will be detoured via southbound 2nd Street to Harrison Street, or via New Montgomery Street to Hawthorne Street to Harrison Street. People on bikes will have a signed detour south at 2nd Street to Folsom Street. From Saturday, Nov. 14, through Friday, Nov. 20, sidewalks in the area will also be affected; the advisory says congestion is expected on 4th Street from Market and on Mission Street between 3rd and 4th from early morning through evening, Tuesday, Nov. 17, through Friday, Nov. 20. The SFMTA encourages taking transit or using alternate routes.

Other work to plan around

Replacement of sewer and water lines continues on Geary Boulevard between 32nd Avenue and Stanyan Street through 2027, and some stops on the 38 Geary and 38R Geary Rapid have been moved because of the work. Over the weekend of Friday, Nov. 13, to Sunday, Nov. 15, a Caltrans contractor is scheduled to pave northbound lanes in a project area between U.S. 101 and 20th Street, with overnight and weekend closures; at least one lane is to remain open, and lane-closure hours are listed as 10 p.m. Friday to 10 a.m. Saturday, the SFMTA said, citing the Fab 4 Rehabilitation project.
