Pavement buckles on WI highways a risk to drivers in extreme heat

Local News

LA CROSSE/EAU CLAIRE, Wis. (WLAX/WEUX) – The State Department of Transportation says when the weather is like this it’s not surprising to see pavement buckles on the roads. So far this year the Wisconsin DOT has already reported 115 incidents of pavement buckling on state highways. That compares to 163 last year and just 105 in 2019.

Devin Harings, The Northwest Region Pavement Engineer for Wisconsin DOT says crews expect to deal with this issue every year. As Wisconsin’s climate includes temperatures that are extremely hot and extremely cold.

Harings said, “As the temperature increases concrete wants to expand what ends up happening is it eventually runs out of room to expand, it will run into another section of concrete, find a weak spot and it will start pushing up on the pavement which causes the buckle.”

As this heat continues the DOT is asking drivers to pay extra attention on the roads and give yourself extra space to stop. Drivers should call 911 if they see a pavement buckle out on the roads, so crews can be called in to shut down the lanes.
