DOUGLAS COUNTY, Colo. — Emergency crews had to make repairs after a stretch of Plum Creek Road near Castle Rock buckled Monday afternoon due to what’s believed to be the heat.

The road buckled between Interstate 25 and the Miller Activity Complex and drivers were asked to avoid the area if at all possible.

Highs at Denver International Airport hit 98 degrees, making it the hottest day of the year and the first in what’s forecasted to be a string of days with highs in the 90s – maybe even the first 100-degree day of 2021.

This forecast prompted the National Weather Service to issue an Excessive Heat Warning for a swath of the Western Slope – the first time this particular advisory has happened in Colorado.

Buckling can happen when concrete slabs of roads start expanding in the heat and press on each other, according to a CDOT engineer. 

This creates stress and if they expand and press too much, the road will buckle at those stress points.
