I-80 snow, icy roads and closures by state
Interstate 80 crosses mountains, high desert, plains and urban areas. A snowstorm in the Sierra Nevada can affect a completely different part of I-80 than blowing snow in Nebraska or Iowa. When planning a trip, check the section of the highway you will actually drive, not only the national forecast. Open the truck-driver snow and wind radar for a wider weather overview.
Nevada — I-80 corridor
Look for road incidents and available camera snapshots along Reno, Winnemucca and the interstate corridor.

Review UDOT winter and pavement reports and official camera information where available.
I-80 Utah road information →Nebraska — blowing snow and wind
See NDOT camera locations on I-80. Camera data does not independently confirm whether the road is open.
I-80 Nebraska cameras →Iowa — road-surface reports
Use Iowa 511 road conditions, temperatures, cameras and any reported travel restrictions.
I-80 Iowa winter conditions →Illinois — Chicago and I-80
Check Illinois cameras and Travel Midwest incidents before approaching interchanges and congestion.

An interstate closure is a real-time legal traffic restriction and cannot be inferred from a weather radar image alone. Check the route-level DOT/511 alerts above, official signs and the state 511 service. A missing alert on this website does not mean the highway is open; coverage and update delays depend on each official source.
For commercial drivers, watch for low visibility, icy pavement, traction or chain requirements, closures, and crosswinds affecting high-profile trailers. Truck driver weather radar helps assess precipitation and forecast wind, while road cameras help show visible conditions at a camera location, when images are available.
