Weekend Overnight Closures in November

During this weekend and next, there will be temporary overnight closures to the Twin Peaks Tunnel including West Portal and Forest Hill stations. These closures are similar to those on previous weekends and only in effect when ridership is low late at night and early in the morning. Bus shuttles will be provided for the KLM lines and will run while additional work is done. Neighbors should expect minimal disruptions as most activity will be inside the tunnel.

Crews plan to use this time to replace and upgrade 33 fire suppression valves, repair superficial cracks and finish replacing the fiber optic cables that aid citywide emergency communications.

The closures and bus substitutions will be on Friday and Saturday nights during the weekends of November 9-11 and November 16-18. There are also multiple weekend closures planned for December -- stay tuned for more information.
