This list ranks the world's cable-stayed bridges by the length of main span (distance between the suspension towers). The length of the main span is the most common way to rank cable-stayed bridges. If one bridge has a longer span than another it does not mean that the bridge is the longer from shore to shore or from anchorage to anchorage. However, the size of the main span does often correlate with the height of the towers and the engineering complexity involved in designing and constructing the bridge. Cable-stayed bridges with more than three spans are generally more complex, and bridges of this type generally represent a more notable engineering achievement even where their spans are shorter. Cable-stayed bridges have the second-longest spans (after suspended-deck suspension bridges) of the types of bridge. They are practical for spans up to around 1 kilometer (0.6 mi). The Russky Bridge in Vladivostok, Russia with its span has the largest span of any cable-stayed bridge. It is longer by than the 2nd place Sutong Bridge over the Yangtze River in the People's Republic of China which it displaced from the first rank on April 12, 2012. The largest span of the still impressive ''Sutong Bridge'' is . ==Completed cable-stayed bridges== This list of largest cable-stayed bridges includes all bridges with a main span of at least 400 metres. This list only includes bridges that carry automobiles or trains. It does not include suspension bridges, footbridges or pipeline bridges. : ''This list is incomplete, so bridge ranks might not be accurate. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of longest cable-stayed bridge spans」の詳細全文を読む スポンサード リンク
