Interstate 80 in Loomis to close April 14-15

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.

According to Caltrans, motorists can expect an eight-mile detour during the closure.

It said the closure is scheduled to start at 11 p.m. Tuesday, April 14 and end at approximately 5 a.m. Wednesday, April 15.

The interstate will close again from 11 p.m. Wednesday, April 15, until approximately 5 a.m. Thursday April 16.

The closure is part of the “Raise80” project, which involves increasing the vertical clearance of nine freeway overcrossings on Interstate 80 in south Placer County.

To avoid inconvenience, Caltrans is advising motorists to allow extra travel time for the detour.

The Horseshoe Bar Road Overcrossing in Newcastle is the fifth structure to be lifted under the “Raise80” project.

The Horseshoe Bar Road Overcrossing over I-80 will close on Sunday, April 12 through Wednesday, April 29 for overcrossing work.

Weather or other unexpected events may prolong the work or cause construction activities to be rescheduled, according to a public advisory released by Caltrans.

It also stated that the nine overpass structures being raised on I-80 are between Magra Road and Loomis in Placer County.

According to Caltrans, 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.

The public advisory noted that when complete, all structures will meet today’s federal clearance standards for high-profile vehicles and national defense.

Completion of the projects eliminates the need for most high-profile vehicles to use local roads as detours.

April 6-10

Interstate 80 (Sacramento County): Work continues on the $133.3 million multi-phase “Across the Top” project to construct about 10 miles of bus/carpool lanes in both directions, repave the highway from West El Camino Avenue to Watt Avenue, and construct about one mile of new auxiliary lanes from West El Camino Avenue to the 80 and 5 interchange.

Caltrans said the eastbound lane shift is in place.

It added that the eastbound express lanes allow commercial traffic (except permit loads).

The project is scheduled for completion by late 2016, the Caltrans advisory stated.
