Abstract:

The three completed cable stayed bridges in the U.S.�Pasco-Kennewick in Washington, Luling-Destrehan in Louisiana and East Huntington in West Virginia�will soon be joined by another half dozen now under construction. Of these, Florida's Sunshine Skyway is the best known. Cable stayed bridges are proving economical in the 700 to 2,000 ft span range, filling the niche between girder and suspension bridges. Designs vary. From one to four plyons and cables arranged in a variety of fan patterns are used to support decks of steel, concrete or hybrids of the two. Because their construction loads differ greatly from their service loads, design engineering and engineering for construction are generally done by two separate firms, the latter working for the contractor.
