Notice of detours on Highway 80

Special to the Tribune

The California Department of Transportation (Caltrans) is alerting motorists that Interstate 80 will be closed overnight in both directions in south Placer County as crews raise the Horseshoe Bar Road Overcrossing.

Motorists can expect an eight-mile detour during the closure scheduled to start at 11 p.m. Tuesday and end at approximately 5 a.m. Wednesday. The interstate will close again from 11 p.m. Wednesday until approximately 5 a.m. Thursday for the "Raise80" project, which is increasing the vertical clearance of nine freeway overcrossings on Interstate 80 in south Placer County. Motorists are advised to allow extra travel time for the detour.

The Horseshoe Bar Road Overcrossing in Newcastle is the fifth structure to be lifted. The Horseshoe Bar Road Overcrossing over I-80 will close at 4 p.m. Sunday through May 6 for overcrossing work. Weather or other unexpected events may prolong the work or cause construction activities to be rescheduled.

The nine overpass structures being raised on I-80 are between Magra Road and Loomis in Placer County. Six of the structures will have the bridge deck raised approximately 2-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, eliminating the need for most high-profile vehicles to use local roads as detours.
