*** Press Release ***

The San Francisco Municipal Transportation Agency (SFMTA), which manages transportation in the city, including the Municipal Railway (Muni), today reminds customers and San Francisco residents and visitors of the continuation of track improvement work on the Muni Metro system, starting Friday. Construction for the Church & Duboce Track and Street Improvement Project and the Carl Street Rail Replacement Project will require bus shuttle substitution on the N Judah Line, disruption to the J Church Line, reroutes of the 22 Fillmore and N Owl and traffic detours the weekend of August 17. These projects are essential to keeping Muni in a state of good repair and will provide pedestrian and street improvements.

The construction hours will be from 8 p.m., Friday to 5 a.m., Monday. Muni service adjustments and traffic detours will need to start an hour earlier at 7 p.m. on Friday and will continue through construction hours. As with the previous construction weekends for these projects, which began in February, the construction dates have been coordinated between both the Church & Duboce and Carl Street projects to minimize inconvenience to residents, businesses, Muni customers, motorists and bicyclists.

During the construction weekend, the N Line will be shut down with substitute service provided by bus shuttles from Ocean Beach to Church Street. No N Line service will be operated in the Metro subway; however, supplemental rail service will be in place between Castro Station and the Caltrain Station at 4th and King streets. The J Church Line will operate between the Balboa Park Station and Market Street. J Line customers will need to transfer between the Church Street Metro Station and the Church Street stop between Market and 15th streets.

  • N Judah bus shuttles will operate all weekend between Ocean Beach and Church Street.

Crews will also install bulb-outs or sidewalk extensions on Carl Street just east and west of Cole Street.
