Contract awarded for Twin Peaks Tunnel, construction expected to start summer 2018
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.
