*** Press Release ***

The San Francisco Municipal Transportation Agency (SFMTA), which manages transportation in the city, including the Municipal Railway (Muni), encourages its customers and San Francisco residents and visitors to consider bicycling to get to work, shopping and entertainment destinations along the N Judah and J Church lines during the upcoming Muni Rail Shutdown.

Starting at 7 p.m. on Friday, May 25, and ending at 5 a.m. on Monday, June 4, the N Judah Line will be shutdown, the J Church Line will be partially shutdown and the 22 Fillmore, 37 Corbett, 43 Masonic and N Owl routes will be subject to rerouting. This work is essential to keeping Muni in a state of good repair and will provide pedestrian and street improvements. The construction dates have been coordinated between both the Church & Duboce and Carl Street projects to minimize inconvenience to residents, businesses, and will only impact four working weekdays.

“Bicycling is a great way to get around and is a superb alternative as we do this critically important work that will help Muni run better and make for safer travel for people on bikes and on foot,” said Edward D. Reiskin, SFMTA Director of Transportation. “There will be disruption, but we are endeavoring to make it as painless as possible. We’re asking everyone who can to bike, walk or even work from home to ensure space on the Muni shuttles for those who cannot.”

“More and more people are discovering how easy, fun and efficient it is to get around San Francisco by bicycle, and the Muni shutdown is a perfect time to start bicycle commuting,” said Leah Shahum, Executive Director of the 12,000-member San Francisco Bicycle Coalition. “With the miles of new bike lanes and better bicycle parking, it’s easier than ever to get around San Francisco by bicycle. We welcome you to join a bike train and discover just how great it is to commute by bicycle.”

Bike Trains and Bike Routes

The San Francisco Bicycle Coalition will be leading commuter convoys along the N and J lines for each workday morning of the shutdown (May 29-June 1). Each “bike train” will leave at 8 am, from Java Beach for the N Line and the main entrance of the Glen Park BART Station for the J-Church Line, picking up people along the way. Each convoy will bring commuters to downtown Market Street by 9 am, traveling at a safe pace, friendly to those new to bicycle commuting. See full bike train schedule at

The San Francisco Bicycle Coalition is also providing a map that shows the bike route equivalents of the N and J lines, as well as some other options for residents who live, work or shop along these transit corridors. More details on the commuter convoys and the N/J-Church bike alternative map can be found at:

Bicycle Route Detours

Bicyclists are advised that there will also be detours along the Steiner/Sanchez route and the connector route from the Wiggle to eastbound and westbound Market Street from Duboce Avenue to allow for track work. Electronic messaging boards will be used in affected areas to alert motorists and cyclists of detours.

All of the dates and details are subject to change and adjustments due to weather, operational or other unexpected conditions.

Once complete, the “shutdown” projects will provide:

  • New track for a smoother, faster ride on Muni
  • Bulbouts to enhance safety and boarding at N Judah Line stops
  • Curb and ramp upgrades
  • Water and sewer improvements
  • Overhead wire pole and streetlight pole replacement
  • Streetscape improvements
