Interstate 80 Subject to Detour Tuesday and Wednesday Nights in South Placer County

COLFAX - The California Department of Transportation (Caltrans) will begin the first structure lift of the “Raise80” project Tuesday, September 23 and Wednesday, September 24 from 10:30 p.m. to 5 a.m. The overpass structure at Magra Road in west Placer County is the first structure to be lifted. During the overnight lift process, all I-80 traffic in both directions will be detoured around the project to the Highway 20/49 corridor, which is a 56-mile route. Motorists are advised to plan their route and time accordingly.

This project will increase the vertical clearance of nine overpass structures on Interstate 80 between Magra and Loomis in Placer County. Six of the structures will have the bridge deck raised approximately two feet, and three of the structures will have the roadway below lowered to achieve the necessary clearance. When complete, all structures will meet today’s federal clearance standards for high profile vehicles and national defense.

Please be advised that all westbound commercial vehicles will be subject to California Highway Patrol (CHP) inspection and escort during the detour. There will be strict speed enforcement on the detour.  Motorists are advised to allow an additional 45 to 60 minutes of travel time.
