ADOT catching up with pavement repair in Flagstaff area

Crews working east of Williams, in Oak Creek Canyon

Paving on I-40PHOENIX – Arizona Department of Transportation maintenance crews remain busy with pavement repairs along northern Arizona highways following an active winter storm season.

During the week of April 3-7, crews are scheduled to add a new layer of asphalt to smooth rough sections I-40 in the Parks area between Flagstaff and Williams.

Asphalt overlays also will continue on State Route 89A in Oak Creek Canyon.

Potholes in the pavement can pop up quickly when moisture seeps into and below asphalt. In northern Arizona, the situation is often exasperated by the combination of freezing overnight temperatures and daytime thawing. The Flagstaff area usually experiences more than 200 daily freeze-thaw cycles each year. Under the pounding of heavy traffic, the stressed pavement can break away.

ADOT also has two projects scheduled later this year along I-40 between Flagstaff and Williams to add a new layer of pavement in both directions.
