CTA Reroutes Two South Side Bus Routes

Two Chicago Transit Authority bus routes serving the South Side are temporarily rerouted due to police activity near 79th Street and Cottage Grove, transit officials said. The #79 79th and #4 Cottage Grove routes are affected by the changes, which are currently in effect. Riders should expect minor delays and allow extra travel time while the reroutes remain active.
The reroutes affect service near a major South Side transit hub where the two routes typically intersect. The 79th Street corridor is a key east-west connection for Chicago's South Side neighborhoods, while the Cottage Grove route provides north-south service through the area. Transit officials said the changes are necessary due to ongoing police activity in the vicinity, though specific details about the incident weren't provided. The CTA classified the alert as causing minor delays and reroutes.

Eastbound #79 79th buses will operate via 79th, King Drive, 76th, Greenwood, and 79th before returning to their normal route, according to the transit agency. Westbound #79 79th buses will travel via 79th, Greenwood, 76th, Cottage Grove, and 79th before resuming regular service. Northbound #4 Cottage Grove buses are temporarily rerouted via Cottage Grove, 83rd, King Drive, 76th, and Cottage Grove before returning to normal routing. Southbound #4 Cottage Grove buses aren't affected by the reroute and will continue operating on their regular route.
The reroutes are currently in effect, though officials haven't announced when normal service will resume. The CTA said the end date for these temporary changes is to be determined and depends on when police activity in the area concludes. Transit officials said they'll restore regular routing once the situation is resolved and it's safe to return buses to their normal paths through the 79th and Cottage Grove intersection.
