CTA Reroutes 5 Bus Routes Near Michigan/Superior

Five Chicago Transit Authority bus routes are operating on detours near Michigan Avenue and Superior Street due to construction work, officials said.

Construction Forces Downtown Detours

The temporary reroutes stem from construction activity at the Michigan and Superior intersection in downtown Chicago, according to the transit agency. The affected routes serve key corridors connecting the city's North Side and lakefront areas to downtown. Officials said the detours are necessary to maintain safe operations while construction work continues. The agency didn't provide details about the specific construction project or its expected duration.

Detailed Reroute Information

Northbound buses will travel via Michigan Avenue, Ontario Street, State Street, Chicago Avenue, and back to Michigan Avenue before resuming normal routes. Southbound buses will operate via Michigan Avenue, Chicago Avenue, State Street, Ohio Street, and Michigan Avenue before returning to regular paths. The detours affect route 3 King Drive, route 4 Cottage Grove, route 146 Inner Lake Shore/Michigan Express, route 147 Outer DuSable Lake Shore Express, and route 151 Sheridan. Officials said the changes are expected to cause minor delays.

Timeline Remains Uncertain

The reroutes took effect Friday, April 10 at 11:20 p.m., but the agency hasn't set an end date for the temporary service changes. Officials listed the duration as to be determined, with restoration of normal service dependent on completion of construction work. Transit officials said they'll announce schedule updates as more information becomes available about the project timeline.

Riders Advised to Plan Extra Time

Passengers using the affected routes should allow additional travel time for their trips, transit officials said. The detours add several blocks to normal routing in the downtown area, particularly for riders traveling between Michigan Avenue stops.
