TRUCKEE — Road improvements on Interstate 80 from the Troy undercrossing to Donner Pass Road in Truckee will begin today, causing intermittent shoulder and lane closures for several weeks.

The project will repair 14 miles of roadway damaged during winter storms by heavy trucks with chains. A polyester concrete inlay will be applied to the roads with lines repainted in affected areas, Caltrans said.

According to a release, daily traffic movement over Donner Summit includes 30,000 passenger vehicles and 6,200 commercial vehicles, wearing down the road over time.

Lane and shoulder closures will take place primarily at night until the work is done. September is the best time for the work, though completion isn’t expected until November. Officials say inclement weather could extend the work into next summer, if this winter’s snow starts early.

In the westbound lanes, closures will take place from 9 p.m. Sunday to 9 a.m. Monday; 3 p.m. to 9 a.m. Monday, Tuesday and Wednesday; 3 p.m. Wednesday to 10 a.m. Thursday; and 5 p.m. Thursday to 9 a.m. Friday.

In the eastbound lanes, closures will take place from 9 p.m. Sunday to noon Monday; from 6 p.m. to noon Monday, Tuesday and Wednesday; 6 p.m. Wednesday to 11 a.m. Thursday; and 7 p.m. Thursday to 9 a.m. Friday.

Full ramp closures may also take place 9 p.m. to 7 a.m. Sunday through Thursday nights.

The $7.5 million project will be supported through $5 million in funding from Senate Bill 1, the Road Repair and Accountability Act of 2017.
