Editing Suspension bridge (section)

===Wire-cable===
[[File:Manhattan_Bridge_2007.jpg|thumb|The [[Manhattan Bridge]], connecting [[Manhattan]] and [[Brooklyn]] in New York City, opened in 1909 and is considered to be the forerunner of modern suspension bridges; its design served as the model for many of the long-span suspension bridges around the world.]] The first wire-cable suspension bridge was the [[Spider Bridge at Falls of Schuylkill]] (1816), a modest and temporary footbridge built following the collapse of James Finley's nearby [[Chain Bridge at Falls of Schuylkill]] (1808). The footbridge's span was 124 m, although its deck was only 0.45 m wide.

Development of wire-cable suspension bridges dates to the temporary simple suspension bridge at [[Annonay]] built by [[Marc Seguin]] and his brothers in 1822. It spanned only 18 m.<ref name="Peters"/> The first permanent wire cable suspension bridge was [[Guillaume Henri Dufour]]'s Saint Antoine Bridge in [[Geneva]] of 1823, with two 40 m spans.<ref name="Peters">{{cite book

In the United States, the first major wire-cable suspension bridge was the [[Spring Garden Street Bridge#2nd bridge: Wire Bridge at Fairmount|Wire Bridge at Fairmount]] in Philadelphia, Pennsylvania. Designed by [[Charles Ellet Jr.]] and completed in 1842, it had a span of 109 m. Ellet's Niagara Falls suspension bridge (1847–48) was abandoned before completion. It was used as [[scaffolding]] for [[John A. Roebling]]'s [[Bridge#Double-decker bridge|double decker]] railroad and carriage bridge (1855).

The [[Otto Beit Bridge]] (1938–1939) was the first modern suspension bridge outside the United States built with parallel wire cables.<ref>[http://www.clevelandbridge.com/Gallery%20Historic.htm Cleveland Bridge Company (UK)] {{webarchive|url=https://web.archive.org/web/20080720172523/http://www.clevelandbridge.com/Gallery%20Historic.htm |date=20 July 2008 }} Web site Retrieved 21 February 2007, includes image of the bridge.</ref>
