CTA Route 66 Adjusts for Viaduct Repairs
CTA Route 66 detours eastbound and westbound for Chicago Avenue viaduct repairs
CTA Route 66 Reroutes for Viaduct Work
Chicago's Route 66 bus will take detours in both directions while crews repair the Chicago Avenue viaduct, transit officials said. The Chicago Transit Authority announced the temporary reroute affects eastbound and westbound service due to Chicago Department of Transportation construction work. Riders should expect longer travel times during the construction period.

Construction Prompts Service Changes
The reroute stems from CDOT infrastructure work on the Chicago Avenue viaduct, a key crossing in the city's transit network. Route 66 typically runs along Chicago Avenue through this area, connecting neighborhoods on the city's North Side. Officials said the construction requires buses to use alternate streets to maintain service while work proceeds. The CTA didn't specify how long the viaduct repairs will take or when normal routing will resume.
Detour Routes Outlined for Riders
Eastbound Route 66 buses will travel via Chicago Avenue, then Milwaukee Avenue, Grand Avenue, and Orleans Street before returning to the regular route on Chicago Avenue. Westbound buses will operate via Chicago Avenue, Wells Street, and Grand Avenue before resuming normal service on Milwaukee Avenue. The detours add several turns to the route compared to the direct path along Chicago Avenue. Officials classified the change as a planned reroute, though they haven't said whether any stops will be temporarily relocated or skipped during construction.
Timeline Details Remain Unclear
The CTA announced the reroute but didn't provide a start date or expected duration for the service change. Transit officials said riders should allow extra travel time while the detours are in effect. The agency typically posts construction-related service changes several days in advance, but specific timing for this reroute wasn't available. Officials said the work schedule depends on CDOT's construction timeline for the viaduct project.
Riders Can Track Service Changes
Passengers affected by the reroute should plan for longer trips and possible schedule adjustments during the construction period. The CTA said riders needing assistance can call 1-888-YOUR-CTA for information about the service change. Moovit provides real-time bus tracking and updated routing information for Route 66 and other CTA services throughout the construction period.
