Around 10:20 p.m. the State Patrol tweeted that eastbound lanes were open. The westbound lanes opened shortly after.
The Colorado Department of Transportation enacted the traction law between Silverthorn and the Eisenhower Tunnel, which means all passenger vehicles are required to have snow tires or chains.
Snow is moving through the mountains and into the Denver area. More traffic impacts are possible.
