Road conditions
Every closure and crash UDOT Traffic is publishing, on one map with the route and mile marker. Below it: the live cameras, Parleys Summit and Little Cottonwood Canyon, the I-80, I-15 and I-70 corridor pages, and what the season does to Utah's highways. For the whole country, see the US closures map.

ReportWhat the UDOT Traffic feed carried over the holiday weekend.
I-15 is Utah's spine, St. George, Cedar City, Provo, Salt Lake, Ogden, about 400 miles border to border. I-80 comes in from Nevada across the salt flats, through Salt Lake, up Parley's Canyon past Park City, and out to Wyoming. I-70 starts at Cove Fort and crosses the San Rafael Swell to Colorado, including about 106 miles between Salina and Green River with no services. US-89 threads the towns the interstates skip, and US-191 drops to Moab and the parks.
Utah winters are canyon stories. Parley's Canyon on I-80 sees chain laws and closures all season. Sardine Canyon on US-89 and US-91 and the Cottonwood canyons above Salt Lake close for storms and avalanche control, and UDOT's restrictions come and go by the hour. Lake-effect snow off the Great Salt Lake can bury one stretch of I-15 while ten miles away is dry. UDOT publishes where its plows are, and a truck on the map is a position, not proof the road is plowed.
Over 25 daily snapshots from September 1 to 25, 2026, MileCheck's archive of the UDOT Traffic feed held 125 unique reports, including 1 closure report and 94 crash reports. The routes with the most reports were I-15, I-80 and I-215. 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 UDOT Traffic 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 UDOT Traffic.
UDOT Traffic is the official source, and dialing 511 in most states reaches the same information by phone. This page reads the same UDOT Traffic feed and adds the Utah cameras, the corridor and pass pages, and your own mile marker if you carry the app.
Chain and traction rules are set by UDOT Traffic per road and per direction, and they change with the storm. Restrictions the DOT publishes as alerts appear on the map above and on the Parleys Summit and Little Cottonwood Canyon pages. Always follow the posted signs. What "chains required" means explains the levels.
Every five minutes. MileCheck's server fetches the UDOT Traffic 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 UDOT Traffic 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. UDOT Traffic 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.
