From February 26 to March 14, the Central Subway (4th & Brannan to Chinatown) will be closed for repairs at Chinatown-Rose Pak Station. Since its opening, the station has had issues with groundwater seeping in. The repair will involve injecting grout behind the platform cavern.

As there are no other crossover tracks except at Chinatown Station, the entire subway will be closed for the repair. During this period, Muni will resume operation of the KT line, as it was before the Central Subway opened. Trains from Bay View and Mission Bay will continue on the N line along the waterfront and then interline with the K line at Embarcadero Station.

The T line shuttle bus will operate between Chinatown and 4th & King Station, running on 3rd Street (to Chinatown) and 4th Street (to 4th & King). This will provide additional service alongside the 30-Stockton and 45-Union/Stockton bus routes on 3rd and 4th Streets. However, the T shuttle will stop adjacent to the T Line platform at 4th Street, while the 30 and 45 stop on Townsend Street, a block away from the Muni Metro platform.
