CTA Route 66 Reroutes for Viaduct Work
Chicago's Route 66 bus will take detours in both directions as construction crews work on the Chicago Avenue viaduct, transit officials said. The Chicago Transit Authority announced the temporary reroute affects eastbound and westbound service, with buses using alternate streets to bypass the construction zone. Passengers should allow extra travel time during the reroute period, though officials didn't specify how long the construction work will last.

Construction Background
The Chicago Department of Transportation is conducting construction work on the Chicago Avenue viaduct, requiring the bus route modification. Transit officials said the reroute was planned in coordination with CDOT to minimize disruptions while allowing necessary infrastructure work to proceed. The viaduct serves as a key crossing point for the route, making the detour necessary for the duration of construction. Officials haven't released details about the scope of the viaduct work or estimated completion timeline.
Detour Routes
Eastbound Route 66 buses will operate via Chicago, Milwaukee, Grand, and Orleans before resuming their normal route on Chicago, according to the transit agency. Westbound buses will travel via Chicago, Wells, and Grand before returning to their regular route on Milwaukee. The detours route buses around the construction zone while maintaining service to nearby areas. Officials classified the change as a planned reroute, though they didn't specify how many trips per day will be affected or whether any stops will be temporarily relocated.

Implementation Timeline
The reroute is currently in effect, transit officials said, though a specific start date wasn't provided in the announcement. The agency didn't release an estimated end date for the detour, noting it will remain in place for the duration of the viaduct construction work. CTA typically updates service alerts as construction timelines become clearer, but additional schedule information wasn't immediately available.
Rider Information
Passengers using Route 66 should plan for longer travel times while the detour remains in effect. The reroute affects service in both directions through the construction area, potentially adding several minutes to trips depending on traffic conditions. Moovit provides real-time bus tracking and updated route information for CTA services, helping riders navigate temporary service changes and plan trips around construction-related detours.
