CTA #77 Belmont Rerouted Near Central

Chicago's #77 Belmont bus is running on a detour route in both directions due to a street blockage near Central Avenue, transit officials said Sunday night. The Chicago Transit Authority issued the alert at 10:14 PM, warning riders to expect extra travel time. The reroute affects service near the Central/Belmont intersection, where buses can't access their normal route.
The detour became necessary when a street blockage made the regular route impassable near Central and Belmont, according to the transit agency. CTA classified the disruption as a minor delay and reroute impact. Officials haven't said what caused the blockage or when crews might clear it. Transit agencies typically implement temporary detours when construction, emergencies, or other obstacles prevent buses from using their standard paths.

Buses traveling in both directions now follow Belmont to Laramie, then turn onto Diversey before reaching Austin, where they rejoin Belmont and resume normal service. The detour adds several turns to what's typically a straight east-west route along Belmont Avenue. Officials didn't specify how much additional time the reroute adds to trips or how many daily riders the route serves. The #77 Belmont normally runs between the Belmont Blue Line station and Cumberland Avenue, serving neighborhoods across Chicago's Northwest Side.
The duration of the reroute remains to be determined, CTA said in its alert. Officials haven't provided an estimated timeline for when buses might return to their regular route. The agency said it'll update riders as conditions change, though it didn't specify how frequently it plans to reassess the situation. Transit officials typically restore normal service once street crews clear obstacles and confirm routes are safe for buses.
