What is the worlds first steel wired suspension bridge?

Answer 1

The Ironbridge at Coalbrookdale in Shropshire, England, completed in 1779, was the first major structure to be constructed entirely of iron.

The first major structure built entirely of steel was the cantilevered Forth Bridge in Scotland, completed in 1890.

Answer 2

Steel Bridge [that was its name] was built in 1888, the first railway span to cross the Willamette River in Portland, Oregon. At the time most rail bridges were made of wrought iron, so its name reflects its then-unusual construction material. The newer bridge, which still stands, built on the same site in 1912, was also named Steel Bridge.

Answer 3

The first major bridge utilizing true steel was the Eads Bridge (1874), the most graceful of the Mississippi River crossings in the USA, built by the Keystone Bridge Company, which subcontracted fabrication of the steel parts to the Butcher Steel Works and the iron parts to Carnegie-Kloman, both of Pittsburgh. Its ribbed, tubular steel arch spans of 502ft, 520ft, and 502 ft (153m, 159m, and 153m) and double-decked design shattered all engineering precedents for the time: the centre span was by far the longest arch. Mathematical formulae for the design were developed by Charles Pfeiffer. The cantilever method of erection, devised by Colonel Henry Flad and used for the first time in the USA, eliminated the centring that would have been impossible in the wide, deep, and fast-flowing Mississippi.
