And if Do you known who developed thoses inventions.
The modern development of the suspension bridge dates from as recently as 1800, when an American judge called James Finlay used towers to elevate the cables and trusses to stiffen the deck. The significance of the towers was that they made it possible for the deck itself to remain perfectly flat for horses and carriages to cross; the significance of the trusses was that they prevented the deck from swaying. This was the first rigid suspension bridge.
Nowadays, we use steel cables, rather than the iron links used by Finlay, but the design remains the same.
The basics of the design
In all modern suspension bridges, the roadway hangs from massive steel cables, which are draped over two towers and secured into solid concrete blocks, called ‘anchorages’, at both ends of the bridge.
