44-468: The bridge stood without the use of metal nails. This was achieved by the careful fitting of the wooden parts and by the construction of the thick girders by clamping and binding them together with metal belts. The main wooden parts of the bridge were covered by sheets of copper for additional durability. The shape and weight of the bridge made it extremely strong at the top, but incredibly weak from underneath. To address concern that flood waters rushing along

55-500: The demand for suitable water transportation channels for industrial use. It was completed in 1965 and assumed a primary role in flood control and irrigation operations. The whole project accounted for the use of 328 ha of land, the relocation of 163 homes and the submersion of the village of Sugano, from which the dam takes its name. As of 2008 its role in flood control has been largely replaced by another dam built in Iwakuni and

66-406: The first time in 50 years. The bridge is composed of five sequential wooden arch bridges on four stone piers as well as two wooden piers on the dry riverbed where the bridge begins and ends. Each of the three middle spans is 35.1 meters long, while the two end spans are 34.8 meters, for a total length of about 175 meters with a width of 5 meters. For nearly three hundred years, the many versions of

77-462: The footbridge remained intact for 276 years, until washed away again in a flood from typhoon Kijia in 1950. It was in a weakened state at the time, as the Japanese had stopped maintaining the bridge during World War II . In 1953, the bridge was reconstructed similar to the original. In 1922, the bridge was declared a national treasure. Between 2001 and 2004, all five bridge girders were restored for

88-406: The old wooden ones. Though thought to be flood-proof, the bridge was destroyed by a flood the next year. As a result, the stone piers were redesigned for greater strength, and a special tax was created to maintain the bridge. This maintenance involved periodically rebuilding the bridge: every 20 years for three spans in the middle, every 40 years for two spans that connect to the banks. Consequently,

99-492: The river would destroy the bridge in its entirety, the bridge was designed so that the wooden pathway merely "floats" on top of its frame using mortise and tenon joints. This allowed rising flood waters to lift out the wooden pathway and carry it off down stream while sparing the main structure. 34°10′03″N 132°10′42″E  /  34.167603°N 132.178367°E  / 34.167603; 132.178367 Nishiki River The Nishiki River ( 錦川 , Nishiki-gawa )
