L Taraval Improvement  Segment B Update  December 18 - 31, 2023

As we wrap up this year, we would like to take some time to share the progress on the project.

First, we want to thank the community for your patience as we have removed and replaced critical infrastructure. We acknowledge that this phase of construction has been most impactful to the community.

The holiday construction moratorium will be observed in the commercial area between 16th and 33rd avenues between 7 am and 10 pm until December 31. Residential areas are not included in the construction moratorium. The moratorium is an opportunity for local residents and merchants to engage for the holidays without construction activity.

“Holidays on Taraval” was hosted by People of Parkside (POPS), Sunset Chinese Merchant Association, and Sunset Mercantile. We kicked off the holidays with a Christmas tree lighting, block party and pop-ups for the community to attend and enjoy on Taraval between 21st and 23rd avenues. The community came to enjoy holiday pleasures and activities. BINGO! was activated with the merchants and played by the community with an assortment of prizes given away.  

We would like to take the time to provide an end of year overview of the work we completed through 2023 and our planned construction for 2024.

2023 we have 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 we will complete: 

  • Remaining water work
  • Remaining sewer work/culverts
  • Track installation with street base
  • Overhead contact System (OCS) work
  • Traffic signals
  • Curb ramps
  • Boarding islands
  • Landscaping
  • Street paving
  • Train and traffic signals
  • Connections to new water and sewer lines

Throughout the project we have been partnering with merchants and residents to lessen the impacts of construction on their daily lives. We have directly responded to and worked with the community on concerns. At times construction schedules were altered or execution reimagined during a construction phase to support those immediately impacted.   

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. 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.  No work is scheduled between December 26, 2023 – January 1, 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.

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

Saturday work anticipated December 16

15th and Ulloa intersection: curved track area - track work, thermite welding and installation

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 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.
  • 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 18th Avenue via a pedestrian access during non-construction hours and weekends.
