L Taraval Improvement Forecast and Project Segment B Update  July 31 - August 12, 2023

In the coming weeks, track work continues with rail installation, and curb ramp work continues with demolition and grading areas in preparation for construction of the new boarding ramps and to upgrade existing boarding ramps. Underground conduit work is being performed to power the new and existing streetlights and OCS poles. Water line and sewer line work continues adding conduits and connections. 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.

Please note the following temporary bus stop changes:

  • The inbound bus stop at Taraval and 15th has been relocated across the intersection until fall 2024.
  • The 66 Quintara is being rerouted from 30th Avenue to 28th Avenue around construction until August 18. Please use alternate stops at 28th Avenue/Santiago and 28th Avenue/Taraval.
  • The 30th Avenue inbound and outbound L Bus stops will be temporarily discontinued until August 18. Please use alternate stops at 28th and 32nd avenues.

  • The 17th Avenue inbound L Bus stop will be temporarily discontinued until September 15. Please use alternate stops at 15th and 19th.

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.

The track area along Taraval Street has been prepped for foundation pours and installation of new rails. Concrete slabs will be poured one block at a time starting at 28th to 29th avenues, 29th to 30th avenues, and 30th to 31st avenues beginning the week of July 17. Each block is expected to take about one week to complete. Expect no parking along the construction area. One side of the road may be briefly closed to traffic while cement trucks pour the concrete. After the curing is complete in the track area work will start on key stops, boarding islands and traffic signals.

Potholing is complete and preparations have begun for track work between 16th and 19th avenues. The middle of Taraval Street will be closed off and excavation will begin the week of July 31. Track work for 22nd to 25th expected to begin August 14.

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

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 from 16th, 17th, 18th, 19th, 29th, 30th, and 31st 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.
