UPDATE: 16th Street Improvement Project

As part of the Muni Forward Program and to improve reliability, speed and increase overall system effectiveness for the key 22 Fillmore route, the 16th Street Improvement Project is part of a larger network of proposed or planned improvements to the Muni system.

There is no active construction scheduled for this weekend.

For more project details and the latest construction updates, visit


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.

Due to ongoing construction on Taraval there will be significant reroutes for a key phase of construction. The bus will reroute off Taraval between 35th and 30th Avenue, and between 26th and 15th Avenue due to multiple segments in various stages of track and transit stop work. There are temporary bus stop changes beginning September 18 to November 22:

  • Inbound stops between 35th and 30th Avenues will be temporarily located on Santiago Street; the outbound stops will be temporarily located on Ulloa Street.
  • Inbound and outbound stops on Taraval between 30th and 27th avenues will remain on Taraval.
  • Inbound and outbound stops between 26th and 15th Avenues will be temporarily located on Ulloa Street.
  • The inbound and outbound bus stops at Taraval and 19th Avenue will be temporarily relocated to 19th Avenue off of Taraval, at the 28 19th Avenue bus stops from September 18 to November 23.
  • The inbound bus stop at Taraval and 17th Avenue will be temporarily discontinued from September 18 to November 23.


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 turns will be allowed when traffic is 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
