Plumas County — Caltrans will begin the Plumas 70 Permanent Restoration project on July 11th, which will provide for the permanent restoration of roadway slope scour in response to the 2017 qualifying storm event that resulted in storm damage along the Route 70 Feather River corridor. A combination of grouted Rock Slope Protection (RSP) clusters at seven locations and a soldier pile "Tie-Back Retaining Wall" at one location will be installed. In addition, eight culverts will be replaced along the route as the roadway embankment undergoes stabilization.
Motorists can normally expect 7 minute daytime delays as work begins in July, but can expect occasional 35 minute delays. The soldier pile wall location near Rich Bar will be reduced to one lane for a half mile length with a temporary traffic signal. Work on this project will happen during daytime hours, Monday through Saturday, from the Plumas County line to the Greenville Wye.
The $20 million project includes 175 working days. The entire project is expected to be completed in 2024.
