*** Press Release ***

The San Francisco Municipal Transportation Agency (SFMTA), which manages transportation in the city, including the Municipal Railway (Muni), today reminds customers, 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 substitution on the N Judah Line and disruption to the J Church Line during the weekend of Nov. 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 will need to start an hour early 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 construction the N Line will be shut down with substitute service provided by bus from Ocean Beach to Church Street at Market Street. No N Line or J Line service will operate in the Metro subway; however, S Shuttles will provide supplemental rail service between West Portal Station and Caltrain Station at 4th and King streets. The J Church Line will operate between the Balboa Park Station and the Church and Market streets. J Line customers will need to transfer between the Church Street Metro Station and the Church Street stop at Market and 15th streets.

Muni Service Impacts

N Judah Bus

  • N Judah bus will operate all weekend between Ocean Beach and Church Street at Market Street.
  • From La Playa to Cole Street the N buses will follow the regular N Line route and stops.
  • The service will run as an express between Cole and Carl streets and Castro Street and Duboce Avenue.

J Church

  • Rail service on the J Church Line will only operate between the Balboa Park Muni Metro/BART Station and Church and Market streets.
  • J Church customers can transfer at Church and Market streets between regular J Line service on the street and Metro subway service provided by the K, L, M and T lines between Church Station and Embarcadero Station.

Traffic Impacts

  • Streets will remain open to cars, bikes and/or pedestrians during the track work on Duboce Avenue
  • Weather permitting, center lane on Church Street between 16th Street and Duboce Avenue will be closed from 12 to 4 a.m., Saturday and Sunday for the paint work
  • Local access will be granted and all local businesses will remain open.

SFMTA Ambassadors will be in the area to provide information and to assist customers at transfer points.

The Nov. 17 weekend work on the Church & Duboce project will include track replacement inside the Muni Metro Tunnel at Duboce Portal. Should weather permits, crews will apply red paint on the center lane of Church Street from 16th Street to Duboce Avenue to make it a transit-only lane. This painting project is part of the Church Street pilot program which aims to reduce delays and improve service reliability for the J Church rail line and 22 Fillmore bus route.

The Church & Duboce Track and Street Improvement Project and the Carl Street Rail Replacement Project are expected to be completed in 2013. No additional weekend shutdown is planned.

These 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
