According to the San Francisco Municipal Transportation Agency, work on the Church and Duboce Track and Street Improvement Project and the Carl Street Rail Replacement Project will result in the multi-day shutdown of the N-Judah between 7 p.m. on May 25 and 5 a.m. on June 4.
The work, which will provide new track for smoother and more reliable Muni service, will also affect the J-Church, 22-Fillmore, 37-Corbett, 43-Masonic and N Owl routes.
SFMTA Director of Transportation Ed Reiskin said the work is critically important and the two projects were coordinated to pose a minimal inconvenience to residents, businesses, transit users, motorists and bicyclists.
"There will be disruption, but we are endeavoring to make it as painless as possible," Reiskin said. "We ask that everyone allow extra travel time and plan ahead."
Buses will run in place of trains on the N-Judah line between Ocean Beach and Van Ness Avenue, although Nx express bus service will be unaffected.
The J-Church line will operate only between Balboa Park and Market and Church streets.
Street and bike lane closures and detours will occur during the construction, when parking restrictions will also be in effect.
