The main span is supported by 272 stay cables with lengths of up to 578m. More than 32.2km of cables built from 200,000t of steel were used for the bridge construction. China Harbour Engineering Company and Second Navigation Engineering Bureau (SNEB) were the main contractors for the project.
Where is the longest cable stayed bridge in the world?
The Sutong Bridge arcs across a 6-kilometer-wide stretch of the mighty Yangtze River 50 miles upstream from Shanghai. Measuring 8.2 km overall, its main span is the current world record-holder for a cable-stayed bridge.
Who built the first cable stayed bridge?
Two German designers, Dischinger and F. Leonhardt, working independently, built the first cable stayed bridges at Stromsund, Sweden (1955) with a 183 metre span and Dusseldorf, Germany (1957) with a 260 metre span. This type of bridge is seen as aesthetically attractive, economic and easier to construct.
What is the maximum length of a cable stayed bridge?
Image of the cable-stayed bridge. Cable-stayed bridges have the second-longest spanning capacity (after suspension bridges), and they are practically suitable for spans up to around 1000 m. The top 10 largest cable-stayed bridges are listed in Table 1.3. The Russky Bridge in Russia has the largest span of 1104 m.
What is the longest single span bridge in the world?
The world’s longest single span is the 1.2-mile main suspension section that’s part of a three-span bridge crossing the Akashi Strait in Japan. The Akashi-Kaikyo Bridge, which opened in 1998, requires 190,000 miles of wire cabling—enough to circle the globe seven times.
What keeps an arch bridge from falling down?
The more weight that was put onto the bridge, the stronger its structure became. Masonry arch bridges use a quantity of fill material (typically compacted rubble) above the arch in order to increase this dead-weight on the bridge and prevent tension from occurring in the arch ring as loads move across the bridge.

What are the strengths of a cable-stayed bridge?
The following are key advantages of the cable-stayed form: much greater stiffness than the suspension bridge, so that deformations of the deck under live loads are reduced. can be constructed by cantilevering out from the tower – the cables act both as temporary and permanent supports to the bridge deck.
What are the benefits of a cable-stayed bridge?
Cable-stayed bridges are far less costly for road-deck lengths of 500 to 3,000 feet (the Bridge Project has a 2,000-foot main span); and they can be built in far less time. They require much less steel cable and use more precast concrete sections, which accelerates construction.
