A cable-stayed bridge has one or more towers (or pylons), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines.
Cable-stayed bridge, bridge form in which the weight of the deck is supported by a number of nearly straight, diagonal cables in tension running directly to one or more vertical towers. The towers transfer the cable forces to the foundations through vertical compression.
Cable-stayed bridges are a subcategory of suspended structures. A cable-stayed bridge is similar to a suspension bridge in having towers and a deck-girder supported by cables; however, its diagonal cables transfer the vertical loads from the deck directly to the towers.
The Russky Bridge over the Eastern Bosphorus in Vladivostok, Russia, with its 1,104 metres (3,622 ft) 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 1,088 metres (3,570 ft) on 12 April 2012.

Today, cable-stayed bridges are a popular choice as they offer all the advantages of a suspension bridge but at a lesser cost for spans of 500 to 2,800 feet (152 to 853 meters). They require less steel cable, are faster to build and incorporate more precast concrete sections.
There are several advantages and disadvantages of a cable-stayed bridge to consider, so these are the key points that you will want to review. List of the Advantages of Cable Stayed Bridges. 1. Cable-stayed bridges take less time to complete than other options.
Cable stayed bridges (Figure 18.5) were introduced immediately following World War II to replace many of the bridges lost during the war. Unlike the suspension bridge, the cables extend from the towers directly connecting to the deck.
The cable-stayed bridge debuted in its full form in the U.S. in the 1970s, decades after engineers in Europe honed the design. Today, because of improvements in structural modeling, this method...
Cable-stayed bridge is a bridge similar to suspended bridge in that it has towers and a deck that is held by cables, but its cables hold the deck by connecting it directly to the towers instead via suspender cables. It usually carries pedestrians, bicycles, automobiles, trucks, and light rail.
A cable stayed bridge has only one set of cables. This results in a bridge that is relatively lightweight in construction, is far less costly than a metal cantilever brides, and uses far less cable than a suspension bridge.
