US Road Conditions & Interstate Weather

Live road conditions for 278 US interstates and states: a radar map of what is on the carriageway, the closures and road blocks currently in force, DOT traffic cameras and the hour-by-hour forecast along the route. Pick a road below.

East–West Interstates

Even-numbered interstates run east to west. Live conditions, closures and DOT cameras along the whole corridor.

North–South Interstates

Odd-numbered interstates run north to south, and these are the ones winter closes first.

Interstates by State

One state’s stretch of an interstate, for the crossings where the weather on the rest of the route says nothing about the drive. Each state’s page lists its own.

Mountain Passes

The summits that decide a winter drive. Live surface conditions, snow, wind and DOT cameras on the climb and at the top.

Road Conditions by State (511)

Every numbered highway in the state, alongside the state’s own 511 service.

Weather Navigation on CarPlay and Android Auto

The same road conditions, radar and closures on the screen in the car, following the route you are actually driving.
