Road conditions
Every closure and crash AZ511 is publishing, on one map with the route and mile marker. Below it: the live cameras, the I-10, I-15 and I-40 corridor pages, and what the season does to Arizona's highways. For the whole country, see the US closures map.

ReportWhat the AZ511 feed carried over the holiday weekend.
I-10 crosses the state for about 391 miles, California line, Phoenix, Tucson, then out to New Mexico. I-40 runs the old Route 66 corridor through Kingman, Williams and Flagstaff, about 359 miles. I-17 climbs from Phoenix at 1,100 feet to Flagstaff at 7,000, mileposts 194 to 341. I-8 heads for San Diego out of Casa Grande through Yuma, US-93 is the Las Vegas run northwest of Wickenburg, and the Loop 101, 202 and 303 freeways ring Phoenix.
Arizona's closures come in two seasons. From mid-June through September, monsoon storms push walls of dust across I-10 and I-8, and flash floods can take out desert highways in minutes. The stretch of I-10 around Picacho Peak, roughly mileposts 211 to 219, is a known dust-storm corridor; ADOT's guidance when a wall of dust hits is to pull completely off, lights out, foot off the brake. In winter the high country gets real snow. I-40, I-17 and SR-87 see closures and icy-grade restrictions the valley never hears about.
Over 25 daily snapshots from September 1 to 25, 2026, MileCheck's archive of the AZ511 feed held 486 unique reports, including 177 closure reports and 136 crash reports. The routes with the most reports were I-10, SR-202 and SR-101. Counts reflect what the feed publishes, so a state whose DOT posts only closures shows only closures. Read the September Highway Report.
The map above shows every full closure AZ511 is publishing as a red marker, crashes in orange, and weather and hazard alerts in blue and purple. Closures the DOT has posted for a future date are listed as scheduled, and ramp and lane closures sit under the toggle so the list stays readable. It reloads every five minutes. If the feed cannot be reached the page says so instead of showing an empty map. For the official list, open AZ511.
AZ511 is the official source, and dialing 511 in most states reaches the same information by phone. This page reads the same AZ511 feed and adds the Arizona cameras, the corridor and pass pages, and your own mile marker if you carry the app.
Every five minutes. MileCheck's server fetches the AZ511 feed, converts it to one format shared by all 50 states, and caches it for five minutes. Each alert also carries the time the DOT last updated it, shown in the list.
Yes. The app shows the same AZ511 alerts on your route, ahead of your position, with the mile marker you are passing. The mile marker works offline in all 50 states. Live alerts are part of MileCheck Premium, $49.99 a year or $9.99 a month after a 7-day free trial.
Your mile marker shows even offline. AZ511 alerts on your route and the nearest camera are part of MileCheck Premium and need a connection to update. Runs on CarPlay and Android Auto.
