Interstate 70 is closed in both directions between New Castle and Silt.
The Colorado Department of Transportation said on its transportation map COTrip that the closure is due to mudslides.
Heavy rain caused flash flooding and mudslides throughout the lower Roaring Fork Valley and Colorado River Valley Monday evening. Residents from Basalt to Silt posted photos and videos to local Facebook groups of cars moving through standing water and mud on I-70, Highway 6 and Highway 82.
Highway 6 was closed for a few hours Monday evening, according to state and county officials, but was reopened around 11:30 p.m.
Garfield County officials urged drivers in an emergency alert to be cautious and not drive through flooded sections of road.
