Culvert work begins in the Feather River Canyon on Sept. 19; expect delays

Caltrans will begin work Sept. 19 on a project to improve water drainage along Highway 70 in the Feather River Canyon. The $426,000 project includes $311,000 in funding from Senate Bill (SB) 1, the Road Repair and Accountability Act of 2017.

“Continued upkeep of drainage systems along State Route 70 in the Feather River Canyon is a necessity,” said Dave Moore, District 2 Director. “Funding assistance from Senate Bill 1 allows these vital repairs to be made quickly to keep culverts in good operating shape prior to the onset of inclement weather.”

Crews will be replacing four culverts on Highway 70 from just west of Grizzly Creek Bridge to just west of Twain Road.  Once work begins, motorists should allow extra travel time as they may encounter one-way traffic control with the possibility of up to 10-minute delays, Monday – Friday during daytime hours.

Motorists are reminded that the law requires them to slow down, obey temporary speed limit reductions, and drive carefully in and around construction areas.  The project is anticipated to be completed by the end of October.  Lamb Unlimited General Engineering is the lead contractor on the project.

SB 1 provides $5 billion in transportation funding annually shared equally between the state and local agencies. Road projects progress through construction phases more quickly thanks to the availability of SB 1 funds, including projects that are partially funded by SB 1.  For more information about other transportation projects funded by SB 1, visit
