Route Master: Sutong Rises High

Sutong Bridge, considered to be the world's longest cable-stayed bridge at 1,088m, is the subject of this article. At a cost of US$1 billion, the bridge spans China’s Yangtze River and is expected to reduce travel time across it from the current one hour to just five minutes once it opens to traffic in 2008. The author notes that once Sutong is completed, China will be able to claim eight of the 10 longest cable-stayed bridges in the world. Outside of China, the other two longest cable-stayed bridges are the Tatara Bridge (Japan) and Normandy Bridge (France), respectively occupying third and fourth place. The article offers a detailed report on elements of the construction process, particularly focusing on the main bridge towers, which at slightly more than 300m high are considered to be the second tallest in the world after the Millau Viaduct (France). The article discusses step-by-step the various construction phases to date. Moreover, to ensure more accurate prediction and control during the project, the builders have employed a tool -- ongoing analysis-prediction-verification-correction – that takes advantage of both the as-built history of the bridge and the changing history of the bridge project.
