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 reroutes affect service near a major South Side intersection where multiple bus routes typically converge. Transit officials said police activity in the area necessitated the temporary service adjustments. The CTA classified the disruption as causing minor delays and reroutes, though specific details about the police activity weren't disclosed. Bus reroutes due to police incidents are relatively common in urban transit systems, typically lasting several hours to a full day depending on the situation.

Detailed Reroute Paths for Affected Lines

Eastbound route 79 buses now operate via 79th Street, King Drive, 76th Street, Greenwood Avenue, and back to 79th before returning to the normal route. Westbound route 79 buses travel via 79th, Greenwood, 76th, Cottage Grove, and 79th before resuming regular service. Northbound route 4 Cottage Grove buses are rerouted via Cottage Grove, 83rd Street, King Drive, 76th, and back to Cottage Grove. Southbound route 4 buses continue operating normally without any detours.

Timeline Remains Uncertain

The CTA hasn't provided a specific timeline for when buses will return to their regular routes. Officials said the end date for the reroutes is to be determined, likely depending on when police activity concludes in the area. Transit agencies typically restore normal service as quickly as possible once public safety concerns are resolved, though officials didn't estimate how long that might take in this case.
