Route 905 Construction

Skanska USA Civil’s Riverside office was awarded this $63 million Design Sequencing contract from Caltrans (California Department of Transportation) for construction of a new section of Route 905 in San Diego.

The contract called for new construction of 2.5 miles of six lane freeway. This project was Phase I of a planned link between the greater San Diego area and the Mexican border.  The new roadway connects with other interstate routes such as I-805, I-5 and the future South Bay Expressway, eases the increased truck traffic through the area and greatly improves the overall flow of all vehicular traffic through the border crossing.

For grading purposes, the project team imported approximately 1.2 million cubic yards of dirt from a CalTrans designated source. The contract also called for construction of five bridges, four culverts, storm drains, landscaping, signal and safety systems and water and sewer lines.

Construction required major grading operations along with placement of 365,000 tons of sub base and base, 103,000 tons of asphalt and asphalt concrete base, and 32,000 cubic yards of concrete pavement. The contract also required 1.7 million cubic yards of roadway excavation. Landscaping, irrigation, electrical, fiber optic and striping completed the project.
