a 1,708-foot-long (521 m) steel cantilever span. Overall length, including the concrete approach spans is 5,305 feet (1,617 m). The approach spans are concrete arches more typical of McCullough's designs. The main roadway is 27 feet (8.2 m) wide with 3.5-foot (1.1 m) wide sidewalks on either side. The main towers rise 280 feet (85 m) above the water surface, with curved sway bracing in a Gothic arch style. The open-spandrel concrete approach arches vary in span from 265 feet (81 m) to 151 feet (46 m). The ends of the bridge are marked by pedestrian plazas meant to provide a viewing point for the bridge and to provide access to the shoreline. These plazas are detailed with

Work on the cantilever arms moved out in both directions from the tower, with the shoreward arm keeping slightly ahead of the center arm so that it would rest on a temporary support structure to stabilize the bridge.
