This list ranks the world's cable-stayed bridges by the length of main span, i.e. the 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 suspension bridges, of bridge types. They are practical for spans up to around . The Russky Bridge over the Eastern Bosphorus in Vladivostok, Russia, with its span, has the longest span of any cable-stayed bridge, displacing the former record holder, the Sutong Bridge over the Yangtze River in the People's Republic of China on 12 April 2012. Completed cable-stayed bridges This list of largest cable-stayed bridges includes all bridges with a main span of at least in length. This list only includes bridges that carry vehicular traffic, such as automobiles or trains. It does not include suspension bridges, footbridges or pipeline bridges. Cable-stayed bridges under construction Planned and proposed bridges Longest cable-stayed bridge decks The definition of cable-stayed bridge deck length used here is: A continuous part of the bridge deck that is supported only by stay-cables and pylons, or are free spans. This means that columns supporting the side span as for example found in Pont de Normandie, excludes most of the side span decks from the cable-stayed deck length. There are some bridges with long bridge decks whose span lengths have not been published, and therefore are missing. Extradosed bridges are not included. The thirty longest decks are: Timeline of world record lengths Many early suspension bridges included cable-stayed construction, including the 1817 footbridge Dryburgh Abbey Bridge, James Dredge's patented Victoria Bridge, Bath (1836), and the later Albert Bridge, London (1872), and Brooklyn Bridge (1883). Their designers found that the combination of technologies created a stiffer bridge. Albert Caquot's 1952 concrete-decked cable-stayed bridge over the Donzère-Mondragon canal at Pierrelatte is one of the first of the modern type, but had little influence
