8/1/11 – Yesterday’s hot weather led to some road buckling again. Officials say just before noon a sheet of concrete on Highway 151 near Hemlock Road blew forcing authorities to close a portion of the highway while crews repaired it. Dodge County Highway Commissioner Brian Field says the heat causes the cement slabs to expand and push against each other up into the air causing them to fail. Field says the failures are time consuming and costly to fix. Each year the county sees about 15 instances of the road buckling, mostly on the state highway that are built with concrete.
