SB 1-Funded I-80 Donner Summit Pavement Project Beginning

PLACER/NEVADA COUNTIES August 12, 2019 – Caltrans is set to begin pavement work on Interstate 80 from the Troy Undercrossing to Donner Pass Road in Truckee to address rutting caused by heavy trucks traveling in the Sierra during winter months when chains are required.

Work on the $7.5 million project is scheduled to begin Wednesday, August 14. $5 million in funding support is provided by Senate Bill 1 (SB 1), the Road Repair and Accountability Act of 2017.

“This segment of Interstate 80 in the Sierra experiences all weather conditions including frequent chain usage during winter storms,” said Caltrans District 3 Director Amarjeet S. Benipal. “With SB 1 funding, Caltrans is able to address the wear and tear caused by chains and heavy commercial truck traffic as goods are transported throughout the state and beyond.”

Interstate 80 is a federally designated primary highway freight system with $4.7 million-plus in commercial goods transported every hour over the Summit. Daily traffic movement over Donner Summit includes 30,000 passenger vehicles and 6,200 commercial vehicles.

Approximately 14 miles of asphalt concrete rutting will be rehabilitated eastbound and westbound with a polyester concrete inlay, a durable material that has been proven to withstand heavy vehicle traffic in all weather conditions. Additionally, 6-inch recessed striping will be replaced in areas affected by rutting to increase motorist awareness during poor weather conditions.
