This article describes the San Mateo-Hayward Bridge Widening Project, a 4.9 mile (7.9 km) twinning of an existing 30 year old bridge in an active seismic area and over the environmentally sensitive San Francisco Bay. The authors describe the planning work of the California Department of Transportation (CALTRANS) that resulted in the use of the precast concrete substructure and superstructure, consisting of driven cylinder piles, bent cap shells, bulb-tee girders, and stay-in-place deck panels. The bridge was finished with the epoxy-coated reinforcement and an extensive polyurea coating to ensure a good service life (estimated at 125 years). The authors focus on the design, production, and erection challenges, as well as the decisive advantages of using precast concrete construction in environmentally sensitive and earthquake-prone regions. Specific topics include the work platform, barge transport, pile driving, pile cap and girder erection, and the lessons learned regarding superstructure and substructure elements. The article is illustrated with full-color photographs of the bridge under construction.
