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 allow extra travel time for trips through the area.

Police Activity Prompts Service Changes

The reroutes affect a major South Side intersection that serves as a key transfer point for riders traveling through the Greater Grand Crossing and Chatham neighborhoods. Transit officials said the changes are necessary to ensure passenger safety while police operations continue in the area. The CTA classified the alert as causing minor delays and reroutes, though specific details about the police activity weren't disclosed. Transit agencies typically implement temporary reroutes when public safety incidents block normal bus paths or create hazardous conditions for vehicles and passengers.

Duration Remains Uncertain

The CTA hasn't provided a timeline for when buses will return to normal routes. Transit officials said the reroutes will remain in effect until police activity concludes and the intersection is cleared for regular bus operations. The agency typically updates service alerts as situations develop, but specific timing depends on when authorities complete their work in the area.

What Riders Need to Know

Passengers traveling through the 79th and Cottage Grove area should plan for longer trip times and possible schedule changes. Riders waiting at stops directly on the affected intersection won't see buses until normal service resumes.
