Interstate 17 northbound has been closed at the junction of State Route 179, the Sedona turnoff, due to snowfall in Northern Arizona as part of the flurry of winter weather.
Traffic is redirected to southbound I-17 because State Route 89A, the only alternative, remains closed.
*Interstate 40 stretching through Kingman, Flagstaff and Holbrook (milepost 71 to 250) has been closed in both directions due to winter driving conditions.
*I-17 northbound remains closed north of State Route 179. Traffic at this time is being diverted to southbound I-17. Drivers are advised to detour in advance or delay travels to avoid congestion at the turnaround.
*I-17 southbound is closed at Airport Road, about two miles south of Flagstaff. Traffic is being rerouted back to the north. Travel south from Flagstaff at this time is not recommended; no reopen time has been established.
*State Route 89A remains closed from Pumphouse Wash at milepost 386 to Forest Highlands Road at milepost 397 due to winter conditions and resource allocation.
*US 180 between mileposts 236 (Kendrick Park) and 248 (Cedar Ranch)
