Road conditions
Closures and crashes from UDOT Traffic, 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. City traffic cameras: Ogden, Provo and St. George.
The UDOT feed lists 2 closure-type alerts, 1 crash and 0 roadwork alerts on numbered highways right now. Closure-type alerts include lane closures, so read each one. Listed:

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.
In October 2026, MileCheck's archive of the UDOT Traffic feed held 105 unique reports, including 7 closure reports and 89 crash reports. The routes with the most reports were I-15, I-80 and US-89. Counts reflect what the feed publishes, so a state whose DOT posts only closures shows only closures. Read the October Highway Report.
The map above shows full closures from the UDOT Traffic feed as red markers, 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. The page checks MileCheck's feed 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.
This page checks MileCheck's feed every five minutes. UDOT Traffic updates individual reports on its own schedule. Source update times are shown when available.
