Paving continues on Interstate 40 in northern Arizona

Drivers on Interstate 40 in northern Arizona are advised to plan for travel delays because of traffic realignment and ramp closures at Garland Prairie and Pittman Valley roads. Crews are repairing 17 miles of pavement on I-40 between Parks and Williams. The project also includes making bridge deck repairs at Garland Prairie and Pittman Valley roads.

Beginning in August, as crews complete work to rebuild 5 westbound miles between mileposts 167 and 172, all traffic will be moved to the westbound lanes using a temporary crossover in that section. Crews will begin work on the eastbound section of the freeway and will close the eastbound on- and off-ramps at Garland Prairie and Pittman Valley roads for the next few months. Traffic will be detoured onto the Parks and East Williams traffic interchanges.

On July 30, the following ramp closures are scheduled to be in place:

The westbound on- and off-ramps at A-1 Mountain Road will be closed from 7 a.m. to noon. Traffic will be detoured to Bellemont, exit 185, to re-enter eastbound I-40 towards A-1 Mountain Road.
The eastbound on- and off-ramps at A-1 Mountain Road will be closed from noon to 5 p.m. Traffic will be detoured to Business Loop, exit 191, to re-enter westbound I-40 towards A-1 Mountain Road.


On August 3, the eastbound on-ramp and westbound off-ramp at Parks are scheduled to re-open after being closed for a few weeks while crews rebuilt a 1-mile section of I-40 in both directions near the interchange.

Work on this 5-mile section of I-40 is anticipated to wrap up by the fall.

Meanwhile, crews continue to repave other portions of the highway between mileposts 162 and 179 from Cataract Lake to Parks.

Construction will pause for the winter season and is scheduled to resume in spring 2019 for additional paving, bridge and intersection work. The project is scheduled for completion in late 2019.

What to expect:

  • Crews are scheduled to work Mondays through Fridays from 5 a.m. to 6 p.m.
  • Lane closures, ramp closures and restrictions will be required
