This project was funded with a Joint Power Authority (JPA) between Metropolitan Transportation Commission (MTC) & Bay Area Toll Authority (BATA). The project segment along Interstate 880 (I-880) is approximately 25 miles long, from north of Route 237 to north of Hegenberger Road, in Santa Clara and Alameda Counties. Improvements included conversion of the existing High Occupancy Vehicle (HOV) lanes into express lanes for both north and southbound directions of I-880. The existing freeway was widened in areas with proposed ingress and/or egress weave lanes. Overhead signs and gantries were installed in the median for required power and telecommunications. Median concrete barriers were modified at overhead sign locations and existing California Highway Patrol observation areas. PARIKH provided Geotechnical Reports for all project elements, including roadway widening and the 61 overhead sign structures. All work was completed on schedule, within budget, and in accordance with Caltrans standards.
