*** 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 this month. 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 several bus routes and traffic detours over multiple days, Friday, May 25 until Monday, June 4. This work is essential to keeping Muni in a state of good repair and will provide pedestrian and street improvements.

As part of the Church and Duboce Track and Street Improvement Project and the Carl Street Rail Replacement Project, the multi-day shutdown is slated to begin at 7 p.m. on Friday, May 25, and end at 5 a.m. on Monday, June 4. It will require a shutdown of the N Judah Line, a partial shutdown of the J Church and reroutes on the 22 Fillmore, 37 Corbett, 43 Masonic and N Owl routes.

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. The projects will revitalize the Muni system by upgrading Muni tracks and essential systems and provide numerous streetscape and infrastructure improvements to the surrounding neighborhoods.

“This shutdown will enable critically important work that will help Muni run better and make for safer travel for people on bicycles and on foot.There will be disruption, but we are endeavoring to make it as painless as possible,” said Edward D. Reiskin, Director of Transportation. “We ask that everyone allow extra travel time and plan ahead, especially when commuting or going to events. Those who can walk, bike, take an alternative Muni route, grab a taxi, or even work from home will help ensure space for those who cannot.”

Construction crews and equipment will be on site working around the clock during construction, beginning at 8 p.m., Friday, May 25.

  • The N Judah will be shutdown with substitute bus service provided from Ocean Beach to Van Ness Avenue.
