US 180 will be narrowed to one lane between Flagstaff and Valle (milepost 250 to 265) starting on Monday (Aug. 3) through Thursday (Aug. 6) from 6 a.m. to 6 p.m. The restriction is required to allow Arizona Department of Transportation crews to perform maintenance work on the roadway.

During maintenance operations, heavy delays can be anticipated. A pilot car will allow for alternating travel through the work zone. Please allow for extra time for travel time and exercise caution while moving through the area. Drivers should consider using I-40 and SR 64 as alternate route for travel.
