L Taraval Improvement Project | Segment B Update – December 4 – 16, 2023

In the coming weeks, the holiday construction moratorium will be observed in the commercial area between 16th and 33rd avenues between 7 am and 10 pm. The moratorium is an opportunity for local residents and merchants to engage for the holidays without construction activity. Residential areas are not included in the construction moratorium.  

Track work continues with rail installation, and curb ramp work continues with demolition and grading areas in preparation for upgrading 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. Street lights, 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 staged 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.  

Please note the following impacts to travel during track work:  

  • By car: Taraval Street will be open to through traffic traveling east- and westbound, however, vehicles approaching areas with active track installation 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.
