NDOT says the traffic restrictions are necessary for milling, profiling, and paving operations. The schedule is subject to change due to weather and other factors.

Motorists should use caution while traveling through work zones, and take alternate detour routes, if possible. NDOT works with Waze to inform the public about planned highway restrictions.
