The CTA operates 129 bus routes across Chicago and 35 surrounding suburbs, providing approximately 1.6 million rides on an average weekday.

The CTA hasn't released information about how long the reroute will remain in effect.

Severity Classification Signals Major Impact

The high severity classification indicates significant disruption to Route 91 service, according to the transit agency's alert system. Officials didn't provide specific details about which intersections or neighborhoods along the route are affected. The number of daily riders impacted by the reroute wasn't available.
