A 2017 Jeep Grand Cherokee driven by Dennis L. Hewett, age 69, of Frontenac, Kan., was traveling westbound on I-44 inside the Rolla city limits at 1:49 p.m. Wednesday, when he failed to negotiate a curve in the roadway. His vehicle travelled off the left side of the road into the median where it struck the cable barrier, crossing into the eastbound lane of traffic. It then travelled off the left side of the roadway, striking the separator, before crossing the eastbound exit ramp and finally overturning, before coming to rest off the roadway. He was transported by Phelps County Ambulance to Phelps County Regional Medical Center and then transported to University Hospital in Columbia in serious condition.
