The outbound bus can't use Jones Street between Geary and O'Farrell due to San Francisco Fire Department activity, forcing riders to experience delays. Officials didn't say how long the detour will remain in effect or what specific fire department operation is blocking the street.

Detour Route Details

The Route 27 is using Hyde Street instead of Jones Street between Geary and O'Farrell while the fire department operation continues, according to the transit agency. The detour affects only outbound service on the route. Officials said the temporary routing allows the bus to maintain service while avoiding the blocked section of Jones Street. The agency didn't provide details about how many riders typically use this segment or how much additional travel time the detour adds.

Fire Department Activity Blocks Street

San Francisco Fire Department activity on Jones Street prompted the routing change, transit officials said. The agency didn't specify what type of fire department operation is underway or whether it involves an active emergency, training exercise, or other activity. Transit agencies typically implement detours when emergency services need to close streets for operations. Officials haven't said when the street will reopen to bus traffic or how long the fire department expects to occupy the area.

Service Resumes When Street Reopens

The Route 27 will return to its regular routing once the fire department clears Jones Street, officials said. The agency didn't provide a timeline for when normal service will resume. Transit officials said the situation depends on when the fire department operation concludes. Riders should expect the detour to remain in effect until further notice.

Riders Face Downtown Delays

Passengers on the Route 27 should expect delays while the detour is in place, transit officials said. The agency advised riders to allow extra travel time and check for updates before heading to their stops.
