CTA Reroutes Route 103 Buses Around Blockage

Chicago's Route 103 West 103rd buses are running on a detour due to a street blockage at 103rd and Sacramento, transit officials said. The reroute affects service in both directions, with buses traveling via 103rd Street, Western Avenue, 99th Street, Kedzie Avenue, and back to 103rd Street. The CTA published the high-severity alert November 30, though officials haven't said what caused the blockage or how many stops are affected.

Routine Operational Adjustment

The detour represents standard operating procedure for urban transit systems when street conditions prevent normal routing, according to the transit agency. CTA regularly issues service alerts for temporary reroutes due to street conditions, construction, special events, and emergencies. The agency operates 129 bus routes across Chicago and 40 surrounding suburbs, providing approximately 1.6 million rides on an average weekday. Officials didn't specify whether the blockage stems from construction, an emergency, or infrastructure issues.

Detour Path Details

The reroute takes buses off their normal path near the 103rd and Sacramento intersection, redirecting them through a loop that adds Western Avenue and Kedzie Avenue to the route. Passengers should expect different stop locations along the detour path, officials said. The CTA hasn't released information about how many riders use Route 103 daily or how many stops are impacted by the temporary routing. Officials said riders should allow extra travel time while the detour remains in effect.

Duration Remains Unclear

The CTA hasn't announced when normal service will resume on Route 103. Officials said the blockage resolution may depend on external factors, though they didn't provide specifics. The agency typically updates service alerts as conditions change, but a timeline for the reroute's end wasn't available by publication time.

Rider Information

Passengers using Route 103 should plan for potential delays and different boarding locations along the detour path. The CTA advises riders to check for updates before traveling, as the situation may change.
