On Thursday, SF Muni is closing down the Twin Peaks Tunnel for eight days to perform required maintenance, and it is expected to have a significant impact on light-rail service, officials say.
The K, L, M and S lines will be affected by the closure. The N, J and T lines will not be affected, as those run through the Sunset Tunnel, officials say.
The work also will close the West Portal and Forest Hill stations, Muni says.
A bus bridge will link light-rail riders between those stations and the Castro or Church street stations.
For more information on the closure, visit the SFMTA website.
