L Taraval Improvement Project

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 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 is expected to be completed 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.
