SPRINGFIELD — With thousands of motorists expected to hit the road over the 4th of July holiday weekend, the Illinois Department of Transportation (IDOT) announces road work will be suspended where possible for the weekend to reduce potential congestion and improve traffic flow.

The advance notice of lane closures for the holiday weekend is designed to aid motorists’ travel plans and improve safety.

Starting at 3 p.m. today, IDOT will suspend all non-emergency road work and open up all lanes where possible until midnight Monday, July 4. Some construction zones throughout the state will continue to have lane closures in effect, due to the nature of some projects.
