After more than 100 years of service, the Twin Peaks Tunnel, which carries Muni's K-Ingleside, L-Taraval and M-Ocean View light rail lines between Castro and West Portal Stations, is in need of major maintenance.

Starting Monday, June 25^th and continuing for approximately two months, the tunnel will be closed 24/7. During this time, the Forest Hill and West Portal stations will be closed, and bus service will run for the L-Taraval and M-Ocean View lines.

K-Ingleside light rail will run between West Portal and Balboa Park Stations, where riders can transfer to BART to head downtown. The M-Ocean View bus will also continue serving Balboa Park Station. During weekday morning rush hour (6:00 to 10:00 AM), Muni customers transferring from M buses or K trains to BART at Balboa Park can receive a free BART single-ride ticket good for travel downtown as far as Embarcadero Station.

Please refer to the diagram below for details on substitute service:

And as always, if you have any questions or need assistance with a state agency, please do not hesitate to contact my District Office at 415-557-2312.

Sincerely,

Phil Ting
Assemblymember, 19th District
