A cable-stayed bridge is a type of bridge that 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. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from th. HistoryCable-stayed bridges date back to 1595, where designs were found in Machinae Novae, a book by - inventor. Many early suspension bridges were partially cable-stayed in c. Cable-stayed bridges may appear to be similar to, but they are quite different in principle and construction. In suspension bridges, large main cables (normally two) hang between the towers and are. There are four major classes of rigging on cable-stayed bridges: mono, harp, fan, and star. • The mono design uses a single cable from its towers and is one of the lesser-used examples o.
