The California Highway Patrol at Truckee reports the closure of westbound Interstate 80 at the Highway 20 exit, due to excavation work on a mudslide area.
All traffic is being detoured down Highway 20 through Nevada City, Grass Valley and Auburn before returning to the interstate.
The CHP expects western Nevada County to see a substantial increase in traffic.
