Extreme heat causes Iowa road to buckle upward
The extreme heat now baking many parts of Iowa can be hard on roadways.
A stretch of Highland Road west of Atlantic, Iowa buckled on Saturday, a condition known as a pavement “blow-up.”
“This happens to concrete roads sometimes in the summer,” says Cass County Engineer Charles Marker.
“The concrete expands in the heat and can sometimes rise up as high as a foot to a foot-and-a-half.”
The air temperature in the area Saturday was 93 °F with a heat index of 101 °F
