The U.S. 421 corridor was not designed for speeds higher than 55 miles per hour, said N.C. Department of Transportation division engineer Joseph Chance.
“Federal guidelines have to be met for pavement, shoulder and median widths before the speed limit can be raised or lowered. The cost of making changes would outweigh the benefits if the road was retrofitted to meet the standards for higher speeds,” Chance said.
Chance added that it’s also important to note that U.S. 421 “is a partially controlled access road with several at-grade intersections along the corridor.”
