It is a com-posite steel truss bridge with a cable assisted main span. Stay cables help support the load, or weight, on the bridge and are necessary to have 600-foot spans between the river piers. The use of optimization techniques in the design of large and complex structures like extradosed bridges naturally arises as an efficient way to compute the two The first of this type bridge was constructed in Japan in 1994, and Japan has since built at least 29 examples of this bridge type. It is the longest multi-span extradosed bridge in the world, with a main bridge length of 1,920 m (6,300 ft).
