Road conditions
Closures and crashes from WYDOT, on one map with the route and mile marker. Below it: the I-90 and I-80 corridor pages, and what the season does to Wyoming's highways. For the whole country, see the US closures map. City traffic cameras: Cheyenne.

ReportWhat the WYDOT feed carried over the holiday weekend.
I-80 crosses about 400 miles of southern Wyoming, from Evanston through Rock Springs, Rawlins and Laramie to Cheyenne. I-25 runs north from Cheyenne through Casper toward Buffalo. I-90 cuts the northeast corner through Sheridan and Gillette. US-287 and US-26 carry travelers toward the Wind River country, Jackson and the Yellowstone gates.
Wyoming closures come in flavors. Wind restrictions for light trailers and high-profile vehicles, full closures when a ground blizzard takes the visibility, and rolling closures behind crashes, all described by mile range. The Elk Mountain stretch of I-80 between Laramie and Rawlins, around milepost 255, is the one truckers talk about. When the road shuts, traffic waits at Laramie and Rawlins until WYDOT reopens it.
In October 2026, MileCheck's archive of the WYDOT feed held 33 unique reports, including 2 closure reports and 8 crash reports. The routes with the most reports were I-80, I-25 and US-16. 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 WYDOT 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 WYDOT.
WYDOT is the official source, and dialing 511 in most states reaches the same information by phone. This page reads the same WYDOT feed and adds the corridor and pass pages, and your own mile marker if you carry the app.
