WILLIAMS, Ariz. — Northern Arizona drivers on Interstate 40 west of Flagstaff should plan for possible delays while the Arizona Department of Transportation continues improving the roadway surface between Parks and Williams. Several closures of on and off ramps near Williams have beenï rescheduled and will occur through midday June 21.
Drivers are advised to use caution while paving is underway on I-40 and Grand Canyon Boulevard. Both roadways will remain open, but travel lanes will be restricted and the speed limit will be reduced.
ADOT advises motorists to allow extra time in accordance with the following updated schedule:

The eastbound Pittman Valley Road off-ramp will be closed. Detour: Eastbound I-40 drivers accessing Pittman Valley Road will continue to Parks (Exit 178) and re-enter westbound I-40 to Pittman Valley Road.
