The temperatures may be sky-high, but right now the Minnesota Department of Transportation's focus is low, as conditions are perfect for pavement buckling.
"It is that time of year," said MnDOT Spokesperson Kirsten Klein, who added that crews have already seen eight instances of pavement-buckling so far this summer just in the metro.
With cabin traffic picking-up, MnDOT is urging caution.
"When there is a buckle, it's a priority for us," Klein said.
So how exactly does pavement buckle? First, air temperatures must be above 90 degrees. Because of the heat, the pavement expands and eventually buckles.
"We can't predict where they're going to happen," Klein explained. "We know anecdotally they happen usually on kind of older concrete pavements but they can happen anywhere anytime when the temperatures get this hot."
Motorists who come across a pavement buckle are asked to slow down safely and then call 911 to report it.
"We want to make sure that people are off their phones and doing what they can to do to be safe and paying attention when they're driving," she said.
A pavement buckle was spotted on Interstate 35W on Friday afternoon. Crews could be seen working on the buckle from a Minnesota Department of Transportation traffic management camera.
