Traffic control devices and directional signage, including dynamic message boards, have been deployed to guide motorists safely around major closures. Travelers are advised to consider alternate routes or allow additional time to travel known flood prone areas. Regardless, all motorists are urged to be patient, reduce speed and exercise added caution throughout the Metro East region – as traffic patterns and travel times will likely be affected.

Since this is a very dynamic situation, please see the Department’s website,, for the latest information on roadway closures throughout Illinois.
