The Somersville Road/Auto Center Drive segment is the second construction segment along the corridor, between Loveridge Road and Contra Loma Boulevard/L Street. The project will expand the highway from four to eight lanes, including three mixed flow lanes and one High Occupancy Vehicle (HOV) lane, from just west of Somersville Road to just west of Contra Loma Boulevard/L Street. The project includes the reconstruction of the Somersville Road/Auto Center Dr. interchange, freeway auxiliary lanes, and a median wide enough to accommodate mass transit (eBART).
