The Illinois Department of Transportation is warning motorists to be wary of roads buckling in the extreme heat.
"Pavement failures or blowouts occur when prolonged high temperatures cause the road to expand and buckle up or blow out, resulting in uneven driving surfaces," the Department said in a press release on their website.
The likelihood for buckling is increased even more by rain and humidity.
Buckled roads have already been seen in Kansas. The Hays Police Department posted a photo of a heat-buckled road on Tuesday.
