Paragraph 2

The street blockage near the Western and 57th intersection has forced the temporary service modification, according to the transit agency. Officials classified the disruption as causing minor delays but advised passengers to allow extra travel time. The CTA regularly issues customer alerts to keep riders informed about service changes and disruptions affecting their commutes. The agency didn't specify what's causing the blockage or how long repairs might take.

Paragraph 3

The detour affects buses traveling in both directions on one of Chicago's longest north-south routes. Buses continue on Western Avenue to 59th Street, turn east to Damen Avenue, head south to 55th Street, then return west to Western Avenue to resume normal routing. The CTA listed the end date for the reroute as TBD, meaning to be determined. Officials haven't said whether the blockage involves construction, infrastructure damage, or another issue requiring street closure.
