Chicago Bus 73 Reroutes for Bridge Work
CTA's #73 Armitage bus detours via alternate North Side streets during Cortland Bridge work
CTA Reroutes Bus 73 for Bridge Work
Chicago's #73 Armitage bus will detour around the Cortland Bridge while construction crews work on the span over the Chicago River, transit officials said. The temporary reroute affects both eastbound and westbound service, with buses taking alternate paths through the North Side. Officials didn't specify when the bridge work will be completed or when normal service will resume.
Bridge Construction Prompts Service Change
The reroute is necessary to accommodate construction work on the Cortland Bridge, according to the transit agency. CTA classified the change as a planned reroute, indicating the agency coordinated with city officials before implementation. Bridge maintenance and reconstruction projects typically require temporary transit adjustments when work affects roadways used by bus routes. Officials said the detour will remain in effect throughout the construction period, though a specific timeline for the project wasn't provided.
Buses Take Different Paths East and West
Eastbound buses will operate via Cortland, Elston, North Avenue, Kingsbury, Clifton, and Clybourn before resuming the normal route on Racine. Westbound buses will take a different path, traveling via Racine, Clybourn, Sheffield, North Avenue, and Elston before returning to the regular route on Cortland. The detours add several turns and additional street segments to the route in both directions. Officials advised passengers to allow extra travel time during the reroute period, though they didn't estimate how much additional time trips might require.
No End Date Announced for Detour
Transit officials haven't announced when the reroute will end or provided an estimated completion date for the bridge construction. The agency typically updates service alerts as project timelines become clearer, but specific information about the construction schedule wasn't available. CTA said passengers should expect the detour to remain in place until bridge work is finished.
Riders Can Track Detoured Buses
The reroute affects regular riders who use the #73 Armitage to travel between the city's North Side neighborhoods and downtown connections. Passengers unfamiliar with the detour streets may need to identify new boarding locations along the temporary route.
