AUBURN — Caltrans will begin construction Monday, June 17 on a $40.5 million project along State Route 49 in Auburn with funding provided by Senate Bill 1 (SB 1), the Road Repair and Accountability Act of 2017.

The project, which stretches 4.4 miles from the I-80/SR-49 interchange to Dry Creek Road, will rehabilitate existing pavement and drainage, improve operational features and upgrade pedestrian and bicycle facilities. Class II bicycle lanes will be installed northbound and southbound on SR-49 between Elm Avenue and Dry Creek Road, with bike timing loops at each signal to assist bicyclists traveling the four-mile stretch.

“Our rural state highways deserve as much attention as some of California’s large interstates,” said Caltrans Director Laurie Berman. “This SB 1 project will provide upgrades to ease traffic congestion and deliver a smooth ride and accessible facilities for persons with all abilities and varying means of transportation.”

More than 42,500 vehicles and approximately 2,450 trucks travel this stretch of SR-49 daily between Grass Valley and Interstate 80 in Auburn. Primary construction work has been scheduled overnight to reduce impacts to motorists.

“This segment of State Route 49 is a popular commute route for motorists traveling to and from work,” said Caltrans District 3 Director Amarjeet S. Benipal. “Rehabilitation projects like the one beginning in Auburn are part of the Caltrans commitment to multimodal methods of transportation, which improve traffic flow and ease congestion.”

The project has been awarded to Flatiron West, Inc. In addition to improving the highway’s durability and ride quality with 21 lane miles of a Hot-Mix Asphalt (HMA) overlay, construction crews will install new traffic signals at Locksley Lane and Shale Ridge Road. Highway shoulders and pedestrian facilities will also be upgraded to comply with the Americans with Disabilities Act (ADA).

Work is scheduled to begin June 17 and motorists will encounter intermittent single lane closures Sunday afternoon through Friday morning on SR-49. Motorists are encouraged to plan ahead, use alternate routes, and “Be Work Zone Alert.” Construction is anticipated to be completed in summer 2020.
