COLFAX (CBS13) — Interstate 80 and Highway 50 in the high country are back open after going through closures Tuesday morning after a significant snowstorm moved in.

Caltrans says I-80 was closed from the junction Highway 174 in Colfax to the Nevada State Line. Downed power lines are the main issue, along with the whiteout conditions that have popped up at times during the storm.
