Columbia, IL – Motorists traveling through Monroe and St. Clair counties should expect delays this week as the Illinois Department of Transportation begins intermittent lane closures on Interstate 255.
According to IDOT, daytime lane restrictions will take place between Illinois 3 in Dupo and Illinois 3 in Columbia starting Tuesday, Oct. 21, and continuing through Thursday, Oct. 23, weather permitting. Crews will be conducting pavement evaluations as part of ongoing maintenance in the area.
The closures are expected to impact both directions of travel at varying times during the day. Drivers are urged to slow down, remain alert for workers and equipment, and follow all posted construction signage. IDOT also reminded motorists to avoid mobile device use while passing through the work zone.
The project is part of a statewide effort to assess roadway conditions and plan future repairs. Traffic is expected to return to normal by late Thursday evening, pending weather and progress.
