The suspension span is 500 ft (150 m), while the total deck length is 760 ft (230 m); the width is 14 ft (4.3 m). The bridge uses 860,000 pounds (390,000 kg) of structural steel and 350,000 lb (160,000 kg) of reinforcing steel, along with 1,600 cubic yards (1,200 m 3) of concrete. The bridge's deck passes through the main tower's keyhole. [1]
In a plate girder bridge, the plate girders are typically I-beams made up from separate structural steel plates (rather than rolled as a single cross-section), which are welded or, in older bridges, bolted or riveted together to form the vertical web and horizontal flanges of the beam. In some cases, the plate girders may be formed in a Z-shape ...

The mast was constructed of cone-shaped steel plate sections welded together to form a 3-foot (1 m) base, 7-foot (2 m) midsection and 1.5-foot (.5 m) tip diameter. Glass-enclosed elevator towers on both ends of the footbridge accommodate pedestrians who have difficulty climbing the stairs leading up to either end of the bridge from street level.
