I-70 from Kansas City to Denver: road conditions right now
Kansas City, MO to Denver, CO
The 600 miles of I-70 across Kansas and eastern Colorado are flat, fast, and exposed. Upslope storms on the Colorado side close I-70 between Limon and Denver with blowing snow, and Kansas ice storms glaze the Hays–Salina stretch.
Checking the forecast, NWS alerts, and DOT feeds for I-70 right now…
Why this stretch is hard in winter
- CDOT closes I-70 east of Denver (Airpark to Limon, sometimes to Burlington) with safety closures when visibility drops.
- Eastern Colorado has almost no services between Limon and Burlington; do not start the last leg into a warning.
- Kansas freezing-rain events are frequent from December to February and are underestimated by drivers used to snow.

Questions drivers ask about I-70
- Why does CDOT close I-70 east of Denver?
- Because blowing snow on the open plains drops visibility to zero and there is no safe place to stop for 60 miles. Closures are announced on COtrip and usually last until the wind drops. This page shows active NWS warnings and hourly gusts along the route.
