L Taraval Improvement Project
Segment B Update – June 17 - 29, 2024

The most disruptive work, including sewer, water, rail lines, new streetbase and repaving the entire corridor has been completed. Construction continues with installing boarding islands with accessible curb ramps, handrails and pavers and landscaping. Curve track replacement work at 46th Avenue was completed June 4, 2024, ahead of schedule. The next phase of the project includes: energizing and testing the OCS lines, testing trains, completing installation of boarding islands, landscaping, artwork and safety features. 

Work to replace the Overhead Contact System (OCS) that powers the trains is complete. Workers are preparing the area for re-energizing overhead lines, ground conduits and infrastructure to accommodate testing of the trains. If you are driving or working in the area, please stay alert as we prepare and initiate preliminary train testing. 

To ensure the safety of the public, a permit is required for any contractors that are planning to work within 10 feet of the overhead wires. Please reach out to the project team with any questions: LTaravalProject@SFMTA.com or 415.646.2379

General construction hours are Monday to Friday between 8 a.m. and 4 p.m. Construction schedules are subject to change. “No Parking” signs will be posted in construction and staging areas. Construction teams may be excavating and jackhammering pavement, which may cause vibrations. Dust control and housekeeping measures are in place at active construction and staging locations.
