The John James Audubon cable stayed bridge will incorporate many advanced features that represent the state of the art in cable stayed bridge construction. These features include the galvanized strands for the cables, the high density polyethylene stay pipes with an external helix for wind stability, the anchorage system of the cables inside the towers with steel anchorage boxes, the single inspection traveler running along the bottom of the whole deck, the provision of elevators inside the towers, the simplicity of design of the towers and of the deck, and the efficient semi-fan arrangement of the cables. All of these features are combined with the most advanced design provisions for withstanding extreme events like vessel collision, hurricane force winds, sudden loss of one cable or the scouring action of the river.
