Interstate 680 HOV Completion and Express Lanes

The project provides a continuous High Occupancy Vehicle lane on I-680 in the southbound direction between the Martinez-Benicia Bridge and the Contra Costa/Alameda County line. In the northbound direction, the project shortens the existing gap between Livorna Road and State Route 242. Both directions are necessary to encourage carpooling and provide the necessary infrastructure for Express Buses in the corridor.
