SF's OB 1 Adapts Route to Keep Riders Moving

San Francisco's OB 1 bus line detours through Powell, California, Leavenworth streets

OB 1 Route Rerouted in San Francisco

San Francisco's OB 1 bus line is running on a detour through downtown streets after barricades blocked the regular route, transit officials said. The reroute sends buses via Powell, California, Leavenworth, and Sacramento streets, affecting stop locations and travel times for riders along the corridor. Officials classified the disruption as high severity, though they didn't specify when normal service will resume.

Barricade Forces Service Modification

The detour became necessary when barricades appeared along the OB 1's usual path, forcing transit planners to implement an alternate route through the downtown area. Transit agencies typically reroute buses when construction, special events, or street closures block regular paths. Officials didn't provide details about what caused the barricades or how long they'll remain in place. The agency announced the change February 7, alerting riders to expect modified service until the obstruction is cleared.

Detour Affects Multiple Downtown Streets

The temporary route takes OB 1 buses through four downtown streets instead of the regular path. Riders will find buses traveling along Powell Street before turning onto California, then Leavenworth, and finally Sacramento streets. Officials didn't release information about which specific stops are temporarily relocated or how many stops are affected by the detour. The reroute adds travel time to trips, though transit officials haven't quantified the expected delays.

Service Change Timeline Unclear

Transit officials announced the reroute February 7 but didn't provide a timeline for when the OB 1 will return to its regular route. The duration depends on how long the barricades remain in place, though officials haven't said what's causing the obstruction or when it might be removed. Riders should expect the detour to continue until further notice.

Riders Should Plan for Delays

Passengers who regularly use the OB 1 line should allow extra travel time and watch for temporary stop relocations along the detour route. Officials said riders can expect delays while the reroute remains in effect.
