A morning collision involving Muni vehicles at Market and Sansome snarled F Market service today, forcing outbound streetcars to turn back and producing delays along lower Market Street. Riders were asked to use the Market Street subway between Castro and Embarcadero in both directions while crews worked at the scene. The disruption created longer waits and scrambled transfer options for commuters and visitors during the morning rush.

SFMTA alert and immediate impact

According to a service alert posted by SFMTA, the F Market line experienced a delay at Market/Sansome, and outbound streetcars were operating via a switchback at the Ferry Building. The notice told riders to use the Market Street subway between Castro and Embarcadero stations in both directions while crews cleared the scene. The agency advised customers to expect delays and to allow extra time for travel.

How Muni typically responds

When the F line is blocked, Muni often operates partial service on The Embarcadero and runs bus substitutions or asks riders to transfer via the Market Street subway; the system used similar measures during recent equipment outages, according to ABC7 Bay Area. Those tactics are intended to keep passengers moving downtown while crews repair the track or equipment. Expect staggered arrivals and extra crowding at transfer points when reroutes are in effect.

What riders can do

Riders traveling between The Castro and downtown should take the Market Street subway and transfer at Embarcadero or Montgomery for F-line connections; the F Market & Wharves route page has live status and stop information. If streetcars are operating only along The Embarcadero, transfer points near the Ferry Building and Don Chee Way provide connections north toward Fisherman’s Wharf. If your trip is time-sensitive, consider alternate Muni routes or rideshare until full F service resumes.
