Contra Loma Boulevard / L Street

ContraLoma_0040The Contra Loma Boulevard/L Street segment is the third construction segment along the corridor, between Somersville Road/Auto Center Dr. and Lone Tree Way/A 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 Contra Loma Boulevard//L Street to just west of Lone Tree Way/A Street. The project includes providing a full diamond interchange at Contra Loma Boulevard/L Street, a median wide enough to accommodate mass transit (BART) and eliminating the G Street on- and off-ramps.
