UPDATE: Muni’s Service Network

For details on Muni’s current routes and service, visit individual route webpages or the Muni Routes and Stops webpage.

Since Saturday, Aug. 19, the SFMTA added Muni service to ease crowding and help students get to school. This includes bringing back the 28R 19th Avenue Rapid and bus stop changes to the 29 Sunset to improve travel times.

  • As part of the 29 Sunset Improvement Project, 11 stops have been removed in each direction on the 29 Sunset to improve reliability and make the 29 quicker. The 29 Sunset’s northern terminal have been changed from Baker Beach to 25th Avenue and California Street after 10 p.m. Though some customers may need to start using a different stop, the route is faster, more reliable and less crowded. The new night-time terminal implements the following stops: Bowley Street at Lincoln Boulevard, Bowley Street at Gibson Road, Lincoln Boulevard at Bowley Street and 25th Avenue at El Camino Del Mar. Riders boarding at these stops and traveling south will need to wait for the operator’s layover at California Street.
  • With the return of the 28R 19th Avenue Rapid, the 28 19th Avenue will see a decrease in weekday frequency from every 10 minutes during morning and evening peaks to 12 minutes all day. However, combined weekday frequency with the 28R 19th Avenue Rapid is every six minutes on shared stops along the corridor.
  • To address crowding on the 14R Mission Rapid during the early morning and afternoon school hours, more frequent morning service starts at 6 a.m. and service for students departing schools ramps up around 2 p.m.
  • The 31 Balboa has been extended to Townsend and 4th (Caltrain) serving eight (8) new stops on weekdays only.
  • The 38 Geary service to Geary and 32nd Avenue has been increased from 9 to 11 p.m. on weekends to address evening crowding. The frequency 6 to 8 a.m. on weekends will decrease from 10 minutes to 20 minutes.
  • The southern terminal for the 19 Polk in the Hunters Point Shipyard has been changed to Donahue & Innes, from Galvez Avenue at Hill Drive. All current stops on the line will continue to be served. The terminal has been moved to a location with better lighting to prioritize operator and passenger safety.
  • The 30 Stockton has been terminated at Sports Basement (Crissy Field) until 8 p.m. The northern terminal after 8 p.m. is on Divisadero at Chestnut.
  • Inbound (16448) and outbound (16449) Inbound stops on Sloat at 43rd Avenue served by the 18 46th Avenue and 23 Monterey has been discontinued as part of the Sloat Quick Build Project.
  • The 6 Parnassus and 43 Masonic inbound stop at Parnassus at Hillway (15892) is temparorily out of service due to long-term construction.
  • The 28 19th Avenue, 30 Stockton and 91 3rd Street-19th Avenue Owl eastbound stop at North Point and Larkin (15465) are removed due to long-term construction.
  • The 48 Quintara-24th Street pilot reroute and eastern terminal change to 22nd at Iowa is permanent and will also apply to the 48 Owl. One weekday bus being added to the 48 Quintara-24th Street to address crowding.
  • To improve reliability without sacrificing frequency on the 57 Parkmerced, we are adding a bus on weekdays from 11 a.m. to 7 p.m. This will allow the line to continue providing service every 20 minutes while contending with severe traffic congestion along the route. Weekend frequencies has been changed to 25 minutes from 20 minutes to account for more running time due to congestion.
  • The 55 Dogpatch has been decreased in frequency from 15 minutes to 20 minutes to account for additional running time due to congestion and construction on 16th Street.

UPDATE: 16th Street Improvement Project

UPDATE: L Taraval Improvement Project—Segment B

The L Taraval Improvement project continues construction along Segment B replacing and repairing the infrastructure along the L Taraval line between Sunset Boulevard and 15th Avenue, and on Ulloa Street near West Portal.

The project is a comprehensive infrastructure rehabilitation of sewer and water lines and streetscape project. The project will address safety concerns for customers boarding Muni, address the much-needed rehabilitation of aging sewer and water lines while bringing streetscape improvements to the Taraval corridor for added vibrancy.

Work continues on water lines, as well as on the overhead contact system (OCS) that powers the trains. OCS work has transitioned to underground conduit work to support power to the trains and the new and existing streetlights. Curb ramp work has started with demolition and grading areas in preparation for construction of the new boarding ramps and to upgrade existing boarding ramps. Track work is expected to begin over the next few weeks.

The rail tracks west of the intersection of Ulloa and Madrone streets have been taken offline to facilitate the reconstruction of the water and sewer mains as well as replace the tracks and overhead lines. The upgraded sewer and water lines, permanent boarding islands and increased accessibility will make riding safer and more reliable.

The L Bus now runs between West Portal and the SF Zoo. Customers can transfer to a train at West Portal Station to travel downtown.

To facilitate the project during track in each section (except at 15th Avenue), there are temporary bus stop changes:

  • The inbound bus stop at Taraval Street and 15th Avenue has been relocated across the intersection until fall 2024.
  • The 19th Avenue outbound L Bus stop will be temporarily relocated from the northeast corner to the northwest corner until Friday, Sept. 15.
  • The 17th Avenue inbound L Bus stop will be temporarily discontinued until Friday, Sept. 15. Customers can use alternate stops at 15th and 19th avenues on Taraval Street

Crews are performing track replacement on the L Taraval line, starting with pulling and now placing and setting rails.

The tracks along Taraval Street have been prepped for foundation pours and installation of new rail. Since last month, crews have been working on pouring concrete slabs, block by block from 28th to 29th avenues, then from 29th to 30th avenues, and then from 30th to 31st avenues. Concrete pours will continue from track work between 16th and 19 avenues.

During track work, east and west bound lanes will remain open. Only right turn will be allowed when traffic approaching Taraval Street in areas with rail work.

During construction, the following impacts to travel in the track areas are in effect:

  • No parking along the construction areas will be allowed.
  • By car: Taraval Street will be open to through traffic traveling east- and westbound, however, vehicles approaching from 16th, 17th, 18th, 23rd, 24th and 25th avenues will only be able to access Taraval Street by making right turns. At times, traffic may be stopped briefly to allow large machinery to perform work. Please allow extra travel time.
  • By bus: The L Bus may be rerouted around the construction area when heavy equipment is present.
  • On foot: Pedestrians will be able to cross Taraval Street in the construction area at 30th Avenue via a pedestrian access during non-construction hours and weekends.

Construction is scheduled to take place from 8 a.m. to 5 p.m., Monday through Friday. Extreme weather conditions may impact the construction schedule.

ONGOING: 19th Avenue (CA Route 1) Combined City Project

San Francisco Public Works is leading a multi-agency project to replace aging infrastructure and improve safety along 19th Avenue between Holloway Avenue and Lincoln Way.

Construction work for the first and second segment of this project along 19th Avenue between Lincoln Way and Taraval streets was completed. Construction work for bulbouts in the third and fourth segment along 19th Avenue between Taraval Street and Holloway Avenue is ongoing.

As part of the 19th Avenue Combined City Project, the SFMTA will implement transit priority and safety improvements for people walking along 19th Avenue. The improvements will make it safer to walk, remove stops to make transit service more reliable, and enhance customers’ experiences—on and off the bus.

To improve safety along 19th Avenue, the SFMTA will: 1) install pedestrian bulbs at 19 intersections and transit bulbs at 13 intersections; 2) modify traffic and pedestrian signals to give people who walk more time to cross the street; and 3) extend the bus zone at one intersection. Installing transit bulbs allow Muni vehicles to stop for passengers without having to pull out of traffic, and pedestrian bulbs increase the visibility at intersections of people who walk.

As part of the project, seven Muni stops were removed on 19th Avenue between Irving Street and Ocean Avenue last October. The following Muni routes have been affected with the stop removal:

  • 28 19th Avenue
  • 91 3rd Street/19th Avenue Owl
