CTA Reroutes Route 70 Buses Due to Flooding

Chicago's Route 70 Division bus service is temporarily rerouted at Division and Kostner due to flooding, affecting riders traveling through the intersection. The Chicago Transit Authority issued the alert Sunday evening, March 15, at 9:04 PM, with no timeline provided for when normal service will resume. Buses are being redirected through a detour that adds several blocks to the route.

Detour Route Adds Distance to Regular Path

The temporary detour redirects buses via Division, Cicero, Augusta, and Kostner before returning to the regular Division Street route, transit officials said. The reroute is one of several service alerts currently affecting CTA bus routes across the system. Flooding at street intersections typically requires reroutes until water recedes and city crews can assess road conditions for safe bus operations. The agency classified the disruption as causing minor delays, though specific delay times weren't provided.

Service Disruption Continues Without End Date

The reroute remains in effect with no specified end date, according to the transit agency. Officials said they're monitoring the flooding situation but haven't announced when they expect to restore normal routing through the Division/Kostner intersection. The agency didn't provide information about the extent of flooding or what caused the water accumulation at the intersection. Transit officials said they'll update riders when conditions allow buses to resume their regular route, but a timeline for that assessment wasn't available.

Agency Advises Extra Travel Time

Passengers using Route 70 should allow extra travel time due to the extended detour path, CTA officials said. The agency continues to monitor conditions at the affected intersection and will notify riders when normal service resumes. Officials didn't specify how much additional time riders should plan for their trips or which stops along the route might experience the longest delays.

Riders Can Track Service Changes

The reroute affects riders traveling through Chicago's Division Street corridor, particularly those boarding or alighting near the Kostner intersection. Transit officials said passengers can stay informed about service status through CTA communication channels, though the agency didn't provide specific guidance on how riders near the affected intersection should adjust their travel plans.
