CTA Reroutes #79, #4 Buses for Police Activity

Chicago's #79 79th and #4 Cottage Grove buses are running detours near 79th Street and Cottage Grove due to police activity, the Chicago Transit Authority said Monday night. The reroutes began at 11:29 PM and affect multiple directions on both routes. Officials haven't said when normal service will resume.

Police Activity Prompts Service Changes

The temporary reroutes stem from ongoing police activity at the 79th Street and Cottage Grove intersection, according to the transit agency. CTA classified the disruption as causing minor delays and reroutes. The agency typically implements detours when public safety incidents block normal bus paths or create hazardous conditions for passengers and operators. Officials didn't provide details about the nature of the police activity or how long the area might remain restricted.

Multiple Routes Affected by Detours

Eastbound #79 79th buses now operate via 79th, King Drive, 76th, Greenwood, and 79th before returning to their normal route. Westbound #79 buses travel via 79th, Greenwood, 76th, Cottage Grove, and 79th. Northbound #4 Cottage Grove buses are rerouted via Cottage Grove, 83rd, King Drive, 76th, and Cottage Grove before resuming normal service. Southbound #4 buses aren't affected by the changes, officials said.

No Timeline for Service Restoration

The transit agency hasn't announced when buses will return to their regular routes. CTA typically restores normal service once police clear an area and determine it's safe for buses to resume standard operations. Officials advised passengers to allow extra travel time while the detours remain in effect.

Riders Should Plan for Delays

Passengers using the affected routes should expect minor delays and plan accordingly, transit officials said. The detours add several blocks to normal travel paths, particularly for riders boarding or alighting near the 79th and Cottage Grove intersection.
