The extremely high temperatures experienced last week in the area did not cause any road damages caused by heat buckling, according to Door County Highway Commissioner Thad Ash.  The Wisconsin Department of Transportation reported last week that 68 roadways around the state had experienced partial or full road closures due to crumbling pavement brought on by the heat.  Ash believes that area roads have been spared any buckling because of the relatively dry weather conditions.

Ash adds the first sign of a road buckling is when the “tenting” effect causes pavement to heave up due to moisture from under the concrete and subsequent high temperatures.  The DOT reported 163 cases of pavement buckling in 2020.
