CTA Reroutes Two South Side Bus Routes

Two Chicago Transit Authority bus routes on 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 79th and #4 Cottage Grove, with changes currently in effect. Officials haven't said when normal service will resume, and riders should expect minor delays.
The reroutes affect a major transit corridor on Chicago's South Side, where the 79th Street and Cottage Grove intersection serves as a key transfer point for riders traveling between neighborhoods. Transit officials said the changes are necessary to ensure passenger safety while police activity continues in the area. The CTA typically implements temporary reroutes when public safety incidents require buses to avoid specific locations, though officials didn't provide details about the nature of the police activity.
