Pont de Brotonne, first modern cable-stayed bridge of that type, opened to traffic in 1977. [citation needed] Rande Bridge in Spain near Vigo is the highway cable-stayed bridge with the longest and slenderest span in the world at the time of construction (1973–1977). Three long spans of 148 metres (486 ft) + 400 metres (1,300 ft) + 148 metres ...
In an underspanned suspension bridge, also called under-deck cable-stayed bridge, [21] the main cables hang entirely below the bridge deck, but are still anchored into the ground in a similar way to the conventional type. Very few bridges of this nature have been built, as the deck is inherently less stable than when suspended below the cables.

The suspension bridge's architecture is better at handling the load in the middle of the bridge, while the cable stayed bridge is better suited to handle the load closest to the tower. Combining these two architectural engineering ideas into a hybrid has been done in Istanbul with the Yavuz Sultan Selim Bridge , and in New York City with the ...
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. [1] [2]: 85 [3] The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons ...
Unlike other types of bridge, suspension bridges can usually be built without use of falsework or even any access from below the bridge. In many cases, the main cables are constructed first, often with a pilot cable. Construction then proceeds by hanging components and equipment from the main cables.
The longest suspension bridge in the world is the 4,608 m (15,118 ft) 1915 Çanakkale Bridge in Turkey. Cable-stayed bridge: Cable-stayed bridges, like suspension bridges, are held up by cables. However, in a cable-stayed bridge, less cable is required and the towers holding the cables are proportionately higher. [38]
The bridge's construction cost up to €394 million, [2] with a toll plaza 6 kilometres (3.7 mi) north of the viaduct, costing an additional €20 million. The builders, Eiffage , financed the construction in return for a concession to collect the tolls for 75 years, [ 2 ] [ 3 ] until 2080.
