Muni Subway Maintenance Project

Project Introduction

The SFMTA maintenance crews work hard every night after Muni Metro subway service hours to maintain the tracks and equipment underground. On most nights, this gives them only about two hours to get work done. In order to complete critical maintenance tasks that cannot be completed during normal windows, we are planning a week of early subway closures, so crews have more hours each night to do this vital work. This is our ongoing effort to maintain the subway infrastructure to ensure safety and reliability. The last early subway closures for maintenance took place in July 2023.  

DETAILS:

We are planning early subway closures from Friday, March 8, 2024, through Friday, March 15, 2024. The subway between Embarcadero and West Portal will close early at 9:30 p.m. Buses will connect all stops on Market Street, beginning at 9:30 p.m. through the normal end of train service at 12 a.m. while the subway is closed for maintenance. T Third train will provide regular service from Sunnydale to Chinatown until 12 a.m. Owl service will remain unchanged. Trains will start regular morning service each day.

Passengers needing a ramp at Church/Duboce will use the accessible J Line stop at Market/Church.
For service on Market Street, Muni customers can board bus shuttles at bus stops marked with "JKLMN Metro Bus Sub."
Muni customers are encouraged to leave extra travel time during subway closures.
Regular bus fares will apply on bus shuttles and valid transfers will be accepted.
The extended window will give us an opportunity to do complex work aimed at making subway operations more reliable and preventing future breakdowns.

Thank you for your patience and understanding while we improve the safety, reliability and on-time performance of the Muni Metro system.
