L Taraval Improvement Project

Segment B Update – January 1 - 13, 2024


In 2023 we reached a major milestone with the halfway mark of construction. We’re grateful to the community and to our partners at SF Public Utilities Commission and Public Works as we work to replace the critical infrastructure that will serve and support the community for years to come. We acknowledge that this phase of construction has been most impactful to the community. Throughout the project we have been partnering with merchants and residents to lessen the impacts of construction on their daily lives and we will continue to directly respond to and work with the community to address concerns.

Now we look to the new year and all we plan to accomplish. Below is an overview of the work we completed through 2023 and our planned construction for 2024.

    2023 we havReplace water and sewer linese completed:
    Sewer Line Work: 95%
    Water Line Work: 97%
    OCS Work (Foundation and Pole Installation): 95%
    OCS Wiring: 25%
    Track Work (Includes Foundation and Street Base): 65%
   2024 Replacing tracks and building new boarding islandswe will complete: 
   Remaining water work
   Remaining sewer work/culverts
   Track installation with street base
   Boarding islands
   Overhead contact System (OCS) work
   Traffic signals
   Curb ramps
   Street paving
   Train and traffic signals

In 2024 we will continue with track work rail installation, and constructing and upgrading boarding islands, curb ramps, and boarding ramps. Underground conduit work is being performed to power the streetlights and OCS poles. Water and sewer line work continues, adding conduits and connections. Streetlights, boarding ramps, ADA compliant curb ramps, and boarding islands and OCS work continues along this busy corridor. Construction teams will be excavating and jackhammering pavement, which may cause vibrations. Materials are also being temporarily stored nearby. Dust control and housekeeping measures are in place at active construction and staging locations.

Overnight work

Overhead contact system (OCS) pole, overhead wiring and permanent pole placement will be performed along the L Taraval line from Ulloa and Funston to Taraval and Sunset between 10 p.m. and 5 a.m. and expected to be complete June 2024. Work on any given block will vary and is expected to take a few hours to a few days per location.  

General construction hours are Monday to Friday between 8:00 a.m. and 4:00 p.m. Construction schedules are subject to change. “No Parking” signs will be posted in construction and staging areas, and intersections may be closed to through traffic on Taraval Street

*Please be advised that the construction schedule may be impacted by material availability and coordination between agencies.

Multiple agencies are performing infrastructure work in the area. This includes work by Public Works on 19th Avenue, Public Utilities Commission at Vicente and Wawona streets and PG&E along Taraval Street.

Please allow extra travel time.
