Interstate 680 HOV Completion and Express Lanes

The I-680 HOV Completion and Express Lanes project will construct a high occupancy vehicle (HOV) lane on southbound I-680 between North Main Street in Walnut Creek and Rudgear Road in Alamo and convert the HOV lane to an express lane on southbound I-680 from just south of Marina Vista Avenue in Martinez to Rudgear Road in Walnut Creek.
