Interstate 40: Devil Dog to Williams Paving

Project Overview

The Arizona Department of Transportation (ADOT) and the Federal Highway Administration (FHWA) are replacing the existing pavement on Interstate 40 (I-40) between milepost 156 and 161, approximately two miles west of the town of Williams in Coconino County. The project also includes installing new guardrail, and rehabilitating the bridge deck at the Devil Dog Wash overpass.

The project includes completely removing the existing eastbound roadway and replacing the surface with new concrete pavement, and overlaying the westbound roadway with new concrete pavement.  The project will be completed in two phases. The first phase will occur on eastbound travel lanes from August to fall 2017. Construction of westbound lanes will begin in spring 2018 with anticipated completion that fall.

To accommodate travel during construction, temporary crossovers will be built in the median to shift traffic between eastbound and westbound lanes.  A single lane of travel for both directions will be provided at all times, however there will be lane restrictions and reduced speed limits in the area. Drivers should proceed through the work zone with caution, slow down and watch for construction equipment and personnel.

  • Most construction will occur during daylight hours, Monday through Fridays.
  • One lane of traffic for eastbound and westbound travel will be accommodated at all times during construction.
  • Nighttime construction can be anticipated.
