Interstate 40 has ground to a halt in both directions at milepost 151 near Ash Fork after a brush fire flared up late Friday, and the Arizona Department of Transportation says there is still no timeline for when traffic will start moving again. With this key stretch of northern Arizona’s main east–west artery shut down, drivers are facing long waits and serious overnight delays.
According to the Arizona Department of Transportation, crews are working a brush fire at milepost 151 and motorists are being pushed to real‑time traffic tools for any hint of movement. In its post, ADOT said there is "no estimated reopening time." For current road conditions, travelers are urged to check AZ511 or call 511 before heading out.
Where The Shutdown Is Hitting Drivers
Ash Fork sits on I-40 in northern Yavapai County and acts as a small gateway between Flagstaff and Kingman, according to Ash Fork, Arizona. That corridor carries a steady mix of long‑haul freight traffic and regional travelers, and when something goes wrong on this highway, it tends to snarl the region. Past crashes on I-40 have led to hours‑long closures and ripple effects across side roads; AZFamily reported one such lengthy shutdown near Kingman earlier this year.
How To Get Updates And Stay Safe
Transportation officials and traveler information systems are urging drivers to steer clear of closed segments, avoid blocking shoulders so emergency vehicles can get through, and lean on the state’s traffic portal for live maps and camera feeds. The Arizona Department of Transportation has also circulated tips on cutting wildfire risk from vehicles, such as not parking on dry grass and clearing off debris that could spark, as highlighted in a recent advisory from the Emergency Information Network.
This story will be updated as authorities release more details and the interstate reopens. Until then, anyone headed across northern Arizona should plan for serious delays and check AZ511 before committing to a long stretch of I-40.
