The Nevada Department of Transportation (NDOT) is launching a two-year project to repave and enhance two mountain highways in the Lake Tahoe area. As part of the projects, commercial truck restrictions and roadway shoulder closures will begin on Mt. Rose Highway (State Route 431) May 3 . Beginning May 3 through fall, commercial truck through traffic of 26,000 pounds or greater will be prohibited from traveling westbound over Mt. Rose Highway further than the Mt. Rose ski area. Trucks will be allowed traveling eastbound from Incline Village to Reno. The truck closure is a safety precaution to prevent trucks traveling down the mountain potentially encountering brake issues in the road work zone.
