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 Avenue. The CTA issued an alert for routes 79 and 4, which are bypassing the 79th and Cottage Grove intersection. Officials said the reroutes are currently in effect, though they haven't announced when normal service will resume. Riders should expect minor delays and allow extra travel time.

Police Activity Triggers Service Changes

The temporary reroutes affect service near a major South Side intersection that typically sees heavy bus traffic throughout the day. Transit officials said the changes were necessary to ensure passenger safety while police activity continues in the area. The 79th Street corridor serves as a key east-west route connecting neighborhoods across Chicago's South Side, while the Cottage Grove route provides critical north-south service. Officials didn't specify the nature of the police activity or provide an estimated timeline for when buses will return to normal routing.

Detailed Reroute Information for Affected Lines

Eastbound route 79 buses now travel via 79th Street, King Drive, 76th Street, Greenwood Avenue, and back to 79th Street before resuming normal routing. Westbound route 79 buses operate via 79th Street, Greenwood Avenue, 76th Street, Cottage Grove Avenue, and 79th Street. Northbound route 4 buses are rerouted via Cottage Grove Avenue, 83rd Street, King Drive, 76th Street, and back to Cottage Grove Avenue. Southbound route 4 buses continue operating on their regular route without changes, transit officials said.

Duration Remains Uncertain

The CTA hasn't provided a specific timeline for when the reroutes will end, listing the duration as to be determined. Transit officials said they'll restore normal service once police activity concludes and the area is cleared for regular bus operations. The agency typically updates service alerts as situations develop, but officials didn't say how frequently they'll reassess the reroutes.
