The [[Inca]] used [[Inca rope bridge|rope bridges]], documented as early as 1615. It is not known when they were first made. [[Queshuachaca]] is considered the last remaining Inca rope bridge and is rebuilt annually.

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

Line 145:
The principles of suspension used on a large scale also appear in contexts less dramatic than road or rail bridges. Light cable suspension may prove less expensive and seem more elegant for a cycle or footbridge than strong girder supports. An example of this is the [[Nescio Bridge]] in the Netherlands, and the Roebling designed 1904 Riegelsville suspension pedestrian bridge across the Delaware River in Pennsylvania.<ref>As exists with signage re the history.</ref> The longest pedestrian suspension bridge, which spans the River Paiva, [[Arouca, Portugal|Arouca]] [[Geopark]], Portugal, opened in April 2021.

[[Broughton Suspension Bridge]] (England) was an iron chain bridge built in 1826. One of Europe's first suspension bridges, it collapsed in 1831 due to mechanical resonance induced by troops marching in step. As a result of the incident, the British Army issued an order that troops should "break step" when crossing a bridge.
Line 225 ⟶ 227:
[[Peace River Suspension Bridge]] (Canada), which was completed in 1943, collapsed when the north anchor's soil support for the suspension bridge failed in October 1957. The entire bridge subsequently collapsed.
On 30 October 2022, [[2022_Morbi_bridge_collapse|Jhulto Pul]], a pedestrian suspension bridge over the [[Machchhu River]] in the city of Morbi, Gujarat, India collapsed, leading to the deaths of at least 141 people.
