CTA Route 70 Reroutes Due to Division Flooding

Paragraph 1

Chicago's Route 70 Division bus is taking a detour through several West Side streets after localized flooding blocked the normal path near Division and Kolmar, transit officials said Friday night. The CTA issued the alert at 11:13 PM, warning riders in both directions to expect delays. Officials haven't said when the route will return to normal service.

Paragraph 2

The flooding near the Division/Kolmar intersection forced the transit agency to redirect buses away from their regular path. Route 70 Division typically serves as a key east-west connector through Chicago's West Side neighborhoods. Transit officials classified the disruption as a minor delay and reroute impact, though the duration remains to be determined. The CTA operates dozens of bus routes across the city and regularly adjusts service when weather or infrastructure issues block normal paths.

Paragraph 3

Buses now travel via Division, Pulaski, Augusta, and Cicero before returning to their normal route on Division, according to the alert. The detour affects service in both directions at the flooded intersection. Officials didn't specify how much additional travel time riders should expect, but advised passengers to allow extra time when using the route. The agency hasn't released information about how many daily riders use Route 70 or how many trips the reroute affects.

Paragraph 4

The CTA issued the customer alert late Friday night but hasn't provided a timeline for when normal service will resume. The duration is currently listed as to be determined, with restoration depending on when floodwaters recede and the street becomes passable again. Officials said they'll continue monitoring conditions at the Division/Kolmar intersection.

Paragraph 5

Riders on Route 70 should plan for longer trips until the flooding clears and buses return to their normal path. The CTA advised passengers to allow extra travel time when using the route during the detour.
