Route 70 Yuba Bridge Widenings

State Route 70 Yuba Bridge Widenings

This project is located on State Route 70 in Yuba County near Linda and Marysville from 2.4 miles South of Feather River Blvd undercrossing to the Yuba River Bridge and overhead. This project consists of two bridge widenings that span approximately 60 feet in length that required engineering jacking support to lower new structure in place using hydraulic jacking systems. This temporary structure kept the same vertical clearance throughout the construction phase to avoid impacts to traveling public. The widening required partial demolition of existing abutments, footings, and bridge curbs. Other items of work included to upgrade bridge railing with decorative concrete barrier, construct concrete median barrier, polyester overlay and new pavement roadway.
