Part of the sluggish the Twin Peaks Tunnel Replacement Project—a $40 million effort that will refresh the 100-year-old, two-mile metro path underneath Twin Peaks—the Muni tunnel between Castro Street Station and West Portal will close for 60 solid days this summer.
Shuttle service will run between the stations during the tunnel closure.
“Starting in June, buses will substitute for the underground portions of Muni metro trains that use the tunnel, on the K-Ingleside, L-Taraval, and M-Ocean View routes,” reports SF Examiner. ‘A rider guide providing the full schedule and locations of the shuttle bus replacements will be available before the tunnel closures.”
The entire project is slated for completion in winter 2019.
