MADISON, Wis. (WSAU) – State Department of Transportation officials are calling on residents to stay safe and avoid heat damaged roads this weekend.

Since most of the state continues to be under an excessive heat warning over through today, the DOT's Rory Rhinesmith says the danger of heat buckling is the highest today. “We're getting reports of road surfaces over 130 degrees and that's where that damage can really start.”

Rhinesmith says most of that damage is to the state's concrete interstates and high volume roads. “Concrete is more rigid and less flexible than asphalt and it can buckle and relieve itself.” That's where you get cracks, bulges and other damage to the road surface.

Officials are recommending you take basic safety precautions out on the roads. “If you do see distressed road, slow down, move over and call 911.” Rhinesmith says most of the damage to roads can be repaired in 2 to 3 hours, once the state or local authorities are notified. As well, he says drivers should remember that most of these areas occur semi-randomly, so that they should be observant while driving this weekend.
