Caltrans continues work on the Beckwourth Pavement Preservation project, which will completely restore the roadway with paving, and improve ride quality on State Route (SR) 70 in Plumas County. Work includes overlaying 24 lane miles of highway with Hot Mix Asphalt (Type A), rehabilitating the highway at three locations, installing guardrail, paving three existing unpaved pullout areas, and replacing, upgrading or repairing 19 culverts. In addition, TMS elements will be replaced at three locations, along with signage and broadband internet trenching.
The pavement preservation project is located near Portola from just west of Big Grizzly Creek Bridge to about a mile west of Summit School Drive.
Motorists will encounter two closures Monday – Friday during paving operations through the project limits. Expected delays are anticipated to not exceed 10 minutes at the closures. Motorists may encounter work on Saturdays, to include May 30th and some Saturdays in June/July. These two closures will happen intermittently for striping, signage and shoulder work until project completion in July. 24-hour traffic control will be used on unpaved surfaces.
The $21.7 million project includes 150 working days, with all days requiring traffic control. Night work will be used to alleviate traffic delays when feasible and safe. The entire project is expected to be completed in July of 2026.
Hat Creek Construction & Materials Inc., North Region Construction and Caltrans District 2 thank the traveling public and local communities for their patience during the construction of the project.
