Construction of two multi-span concrete bridges elevated Seaside Ave. to allow future unit train services to Piers 300 and 400 on Terminal Island. 7,500 panels of 40 ft.-high MSE walls were erected, resulting in increased cost-efficiencies over traditional cast-in-place retaining walls. During construction, 24-hour access to shipping terminals was maintained.
