UPDATE: Twin Peaks Tunnel Improvements Weekend Early Closures AND 2 Month Total Closure
Present to June 24 Pre-Construction/Weekend Closures: Starting late night Friday and Saturday, and continuing for up to 15 weekends, preparatory work inside Twin Peaks Tunnel will be completed in the early morning weekend hours. To accommodate this work, some stations will be closed early over the weekend:
- Forest Hill and West Portal stations will be closed at 11 p.m. on Fridays and at 11 p.m. on Saturday nights. Stations will reopen the following morning for regular train service. Signage will be posted at the temporary bus stop to denote the K, L and M shuttle stop.
- Castro Station will remain open to trains and become the terminal for S Shuttle and T Third trains that are running. Regular service will return the following mornings.
Buses will operate for K Ingleside, L Taraval and M Ocean View lines, running between Embarcadero Station and each line’s outbound terminal. Buses will run every 20 minutes. Owl service will begin at its regular time. There will be no changes to N Judah, J Church or T Third service.
This preparatory work is being done ahead of the Twin Peaks Tunnel summer closure. In the summer, 100-year-old Twin Peaks Tunnel will be closed for up to 60 consecutive days in order to replace aging tracks and complete major tunnel improvements.
June 25 Full Construction/Total Tunnel Closure: Full construction will require a continuous closure of the tunnel up to 60 days, starting June 25, 2018.
Special Notes: Shuttle service will start the same time as Metro service starts in AM. Frequency will be more often as there will be more buses to cover larger capacity trains. FREE passes on BART for Muni passengers who go to Balboa Park. Free passes will be handed out only between hours of 6 AM and 10 AM.
