TERMINAL ROAD BRIDGES FOR SAN FRANCISCO INTERNATIONAL AIRPORT

THE PLANNING, DESIGN, AND CONSTRUCTION OF TWO PARALLEL ELEVATED ROAD BRIDGES FOR THE SAN FRANCISCO INTERNATIONAL AIRPORT EXPANSION IS DESCRIBED. IT UTILIZES PRECAST, PRESTRESSED INVERTED DOUBLE-T PANELS, CANTILEVERING 22 FT EACH SIDE FROM A CENTRAL SPINAL BEAM WHICH CONTAINS POST-TENSIONED CABLE TO TIE TOGETHER THE PRECAST SEGMENTS. LIMITATIONS IMPOSED BY TRAFFIC AND UNDERGROUND UTILITIES TOGETHER WITH HIGH STANDARDS FOR AESTHETIC AND SEISMIC REQUIREMENTS DICTATED THE PLANNING AND DESIGN OF THE SUPERSTRUCTURE AND THE PIER. OPTIMUM USE OF BOTH PRETENSIONING AND POST-TENSIONING, COMBINATION OF PRECASTING AND CAST-IN-PLACE CONCRETE, TOGETHER WITH INTENSIVE COOPERATION BETWEEN ENGINEERS AND ARCHITECTS HAVE MADE THIS UNIQUE DESIGN A SUCCESS.
