On Tuesday, February 6, the SFMTA Board of Directors approved the resolution to award the Twin Peaks Tunnel Improvements construction contract to Shimmick/ConQuest Joint Venture. The contract bid price accepted was $40.9 million.
Construction is expected to begin later this summer, over a continuous closure of the tunnel up to 60 days. During the closure, Forest Hill and West Portal stations will be closed and buses will run in place of the L Taraval and M Ocean View lines. K Ingleside trains will run a shorter route between Sloat/St. Francis and Balboa Park. More information about what we're doing inside the tunnel and how to get around is available on the Twin Peaks Tunnel project website.
