BISMARCK, N.D. - The record-high temperatures aren't only making Bismarck residents sweat, it's causing havoc on the road.
A spokesman for the I-94 Bis-Man Project says heat fluctuations caused the concrete to buckle on the interstate near the Bismarck Expressway exit on Friday.
Traffic had to be rerouted on the shoulder and slowed to 25 miles-per-hour.
Workers already on scene for regularly scheduled repairs patched up the area in about an hour.
Officials say this kind of incident is exactly why the renovations are needed.
"The efforts that are happening on I-94 are happening now in order to improve the lifespan of the road, to repair potential weakspots and not get the road into such a state of disrepair that the whole thing has to be totally dug up," said Amanda Godfread, I-94 Bis-Man Project.
Officials expect construction work on the interstate to be completed by late fall.
