Repairs to Lassen, Plumas, Tehama county bridges ensure access for commuters, freight

Caltrans today announced it will begin work on Monday, July 24 on a bridge maintenance project to provide needed repairs on 17 bridges in Lassen, Plumas, and Tehama counties, improving travel and facilitating goods movement. Operations on the project will include polyester concrete overlays and joint seal and abutment work. The $5.2 million project is fully funded by Senate Bill 1, the Road Repair and Accountability Act of 2017.

“These bridge repairs are vital for keeping the structures in good shape for the movement of people and goods throughout Northern California and beyond,” said Caltrans Director Tony Tavares. “Thanks to accelerated funding from SB 1, this important project is set to begin soon and will conduct the needed rehabilitation efforts to keep traffic moving safely on these structures for years to come.”

Motorists should anticipate one-way traffic control at most locations, with up to 5-minute delays Mondays to Fridays during daytime hours. Night work is planned for the Susan River Bridge and lane/shoulder closures are planned for the Evans Canyon Undercrossing.
