A section of Highway 421 south will be closed all day Sunday so crews can conduct bridge work.
The closure will start at 11:30 p.m. Saturday, weather permitting, at Dinkins Bottoms Road at exit 249. The road will reopen around 6 a.m. Monday.
The roughly four-mile detour route is Dinkins Bottoms Road and Shallowford Road back to Hwy. 421 south.
The closure is needed so crews can install an epoxy overlay on the bridge crossing the Yadkin River, according to an official with the N.C. Department of Transportation.
