The Illinois Department of Transportation announced Tuesday that nonemergency roadwork will be suspended, where possible, to reduce congestion and improve traffic flow.

Starting at 3 p.m. today all lanes will be open where possible through midnight Sunday. Some construction zones will have lane closures in effect, depending on the projects, according to the news release.

IDOT is urging motorists to slow down, obey posted speed limits and drive with caution through work zones. Holiday travelers are reminded that work zone speed limits are still in effect wherever they are posted, even where no construction workers are present.
