Cromberg Rehabilitation on State Route 70
This project in Plumas County on State Route 70 will rehabilitate nearly 20 miles of roadway near Cromberg from Gill Ranch Road to 0.2 miles west of Big Grizzly Creek Bridge.
The existing pavement will be ground and recycled to create the base, which will elevate and improve vertical and horizontal curves along the roadway. Shoulders will also be widened to current standards providing more room for vehicle recovery.
This project also includes upgrades to guard rail, bridge rail, existing ADA facilities and road connections. Work will also be done to repair, replace or install drainage systems and dikes, overlay the Park & Ride near the State Route 89 intersection, and more. There will be construction of new box culverts, work on rock fencing and electrical work. There will also be additional widening of the road near the Feather River Inn for an intersection improvement project that will be combined with this project.
There are 360 working days for this project which will require traffic control. Construction is scheduled to occur between May 2023 and November 2025.
