Interstate 580 WB HOV Lane Widening

Biggs Cardosa is providing structural engineering services for the widening of approximately 13 miles of westbound Interstate 580 to provide a westbound High Occupancy Vehicle (HOV) lane beginning west of Greenville Road Undercrossing and ending west of the San Ramon/Foothill Road Overcrossing in eastern Alameda County. The project is divided into two construction contracts. As part of the project, several bridge structures will be widened. Widened structures include both street crossings and crossings over creeks. Also included in the project are numerous retaining walls.
