Southbound traffic routed off Highway 395 in Washoe Valley

Southbound traffic on Highway 395 through Washoe Valley has been routed onto Highway 429 at Bowers Mansion due to dense freezing fog.

"Dense freezing fog has made driving conditions extremely challenging," according to Nevada Highway Patrol spokesman Trooper Chuck Allen.

Fog is also reducing visibility along Highway 395 in Carson Valley.

This morning's fog is the topper on what has been a busy weekend for highway patrol troopers.

More than 100 reported accidents occurred on Reno-Sparks highways thanks to a snow storm that hit Western Nevada late Saturday night.

Allen reported that between 5 a.m. and midnight on Sunday, the Nevada Highway Patrol responded to 108 accidents and completed 65 crash reports.

Allen said troopers were busiest between 5-8 p.m. when falling temperatures turned roadways icy.

"Because of the falling temperatures, every roadway that had any amount of moisture had frozen resulting in numerous spin outs and several accidents primarily on Interstate 80 between the California state line and the Keystone interchange," Allen said. "Troopers were so busy that some motorists were asked to complete an office report for any events resulting in minor damage. There were several accidents involving injuries but none had any serious injuries reported."
