SOUTH LAKE TAHOE (CBS13) — While the major Sierra highways are back open as of Wednesday morning, officials are urging people to stay home to keep traffic to a minimum.

Both eastbound and westbound Interstate 80 were reopened on Tuesday after being closed since the holiday weekend. Chain controls are in effect from Colfax to the Nevada State Line.

Heavy snow coated the roadway – and downed trees also proved to be a major issue as well for Caltrans crews.

Highway 50 was reopened first, but people trying to go around the I-80 closure meant a massive backup along the corridor. As of Wednesday, Highway 50 remains open up to the Nevada State Line – but Nevada Gov. Steve Sisolak issued an emergency order to close US-50 at the state line Tuesday night, meaning only Nevada residents will be let through for the time being. All other recreational traffic is being turned at the state line.
