Muni lines will be rerouted and roads will be closed to automobile traffic this weekend in the Castro district due to rail replacement work at Church and Market streets.
The work will begin at 7 p.m. on Friday and last until 5 a.m. on Monday, shutting down Church Street in both directions for through traffic. The westbound side of Market Street will also be shut down, according to the San Francisco Municipal Transportation Agency, which is overseeing the two-year rail replacement project.
Several Muni lines will be affected by the construction work. J-Church trains will only operate between Balboa Park Station and Market and Church streets. Passengers can board an underground shuttle train at Church Street Station to travel between the Castro and downtown. The F-Market historic streetcar lines will not travel further west than Ninth and Market streets, although service will be replaced by Muni shuttle buses. The 22-Fillmore, the 37-Corbett and the N-Owl will also be rerouted to avoid the construction work at Church and Market streets.
