Caltrans will start the final season of work on the Cromberg Combined Rehabilitation project, which will completely restore the roadway, and improve ride quality on State Route (SR) 70 in Plumas County. The project also includes shoulder widening, new guard railing, bridge rail, upgrades to existing ADA facilities, drainage improvements and the addition of numerous safety features.
(Location 1): Tentatively starting April 6th, there will be traffic control on SR 70 near Cromberg while drainage work begins. Motorists can anticipate traffic control Monday – Friday, from 7 a.m. to 5 p.m. at this location. Expected delays may extend up to 10 minutes.
(Location 2): Tentatively starting April 6th, there will be traffic control on SR 70 east of Portola while roadway widening work begins. Motorists can anticipate traffic control Monday – Friday, from 7 a.m. to 5 p.m. at this location. Expected delays may extend up to 15 minutes.
Total delay time through the project limits at both work locations may extend up to 25 minutes.
The $101 million project includes 360 working days, with all days requiring traffic control. Night work will be used when feasible and safe. The entire project is expected to be completed by winter of 2026.
Contractor Mercer-Fraser Company, North Region Construction and Caltrans District 2 thank the traveling public and local communities for their patience during the construction of the project.
