PreScience provided Structure Representative Services. The Santa Ana Freeway (I-5) high occupancy vehicle (HOV) / Rosecrans and Bloomfield Avenue Bridges Project extends from Shoemaker Avenue to Silverbow Avenue in the City of Norwalk. The project will widen one mile of I-5 to add one High Occupancy Vehicle Lane (also known as HOV or car pool lane) and one general purpose lane in each direction. Three bridges will be reconstructed to accommodate the widened freeway, including Shoemaker, Rosecrans and Bloomfield avenues, as well as a pedestrian overcrossing at Silverbow Avenue. The Rosecrans and Bloomfield Avenue Project includes shoulder widening, concrete median barriers, new ramp designs and realignment to Firestone Boulevard.
