CTA Route 73 Reroutes for Cortland Bridge Work
Paragraph 1
Chicago's Route 73 Armitage bus will detour around the Cortland Bridge over the Chicago River while construction work takes place, the Chicago Transit Authority announced. Eastbound and westbound buses will follow alternate paths through the North Side, with riders advised to allow extra travel time. Officials didn't specify when the reroute began or how long the bridge work will last.
Paragraph 2
The reroute accommodates planned construction on the Cortland Bridge, a key crossing over the Chicago River that connects neighborhoods on the city's North Side. Bridge maintenance projects typically require temporary traffic restrictions to ensure worker safety and allow equipment access. The CTA classified the change as a planned reroute, indicating the agency coordinated with city officials before implementation. Transit agencies generally provide advance notice for construction-related service changes, though specific details about rider notification weren't available.
Paragraph 3
Eastbound Route 73 buses will travel via Cortland, Elston, North Avenue, Kingsbury, Clifton, and Clybourn before resuming the normal route on Racine, according to the transit agency. Westbound buses will operate via Racine, Clybourn, Sheffield, North Avenue, and Elston, then return to the regular route on Cortland. The detours add several turns and additional street segments to both directions of service. Officials haven't said how much extra travel time riders should expect or whether the reroute affects service frequency.
Paragraph 4
The CTA hasn't announced when the Cortland Bridge work will be completed or when Route 73 will return to its normal path. Transit officials said passengers should allow extra travel time during the construction period. The agency typically updates service alerts as project timelines become clearer, though a schedule for additional information wasn't provided.
Paragraph 5
Route 73 riders can expect the detour to remain in effect until bridge construction wraps up, with the alternate route affecting access to some regular stops along Cortland. Officials said the reroute is necessary to accommodate the construction work safely. Moovit provides real-time bus locations and updated route information for CTA services, helping riders navigate temporary service changes throughout Chicago's transit network.
