L Taraval Improvement Forecast and Project Segment B Update  April 24 - May 6, 2023

Route(s) Affected

In the coming weeks, work continues on water lines and sewer lines. Underground conduit work is being performed to power the new and existing streetlights and OCS poles. Curb ramp work continues 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 starting with the rail assembly. The tracks along Taraval Street are being prepared for the initial removal and installation of new rails. 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.

The inbound bus stop at Taraval and 15th has been relocated across the intersection until fall 2024.

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.

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.
