Starting Sunday, August 1, N.C. Department of Transportation crews will narrow lanes on an Interstate 77 North ramp for one month.

The I-77 North ramp to Interstate 40 East will be narrowed to 15 feet to allow the construction of a new ramp.

A detour will be posted for vehicles with oversized loads from I-77 to U.S. Highway 21 (Exit 54) to I-40 East. The detour will allow loads of up to 20 feet wide and 16.5 feet high.

Message boards and overhead boards will be set to alert drivers in advance.

Motorists should observe signs and use caution while driving through the area.
