This project is part of Caltrans’s initiative to provide long life pavement rehabilitation through the Interstate 710 corridor. As part of this initiative, Shimmick and its JV partner replaced 34 lane miles of existing pavement with new pavement. The new pavement includes three different types: Jointed Plain Concrete Pavement; Jointed Plain Concrete Pavement (Rapid Setting Concrete); and Precast Prestressed Concrete Pavement.
This was the largest Precast Prestressed Concrete Pavement project in the nation at the time of construction. Along with this long life pavement rehabilitation, Shimmick widened the 710 corridor to improve the safety shoulders throughout the limits of the projects. As part of this improvement, seven existing bridges were also widened and one new bridge was constructed. Shimmick also made improvements to the existing concrete median barrier and the metal beam guard rail.
