世界上最长的行人悬索桥穿过瑞士山谷
World's longest pedestrian suspension bridge traverses a Swiss valley

瑞士阿尔卑斯山的勇敢徒步旅行者现在可以步行近半公里,穿过这条薄金属悬索桥,到达山谷的两侧。
Brave hikers in the Swiss Alps can now walk almost half a kilometre across this thin metal suspension bridge to reach trails on either side of a huge valley.
Charles Kuonen Hängebrücke也被称为欧洲大桥,横跨在瑞士最深的山谷上方,这个山谷的两侧是Zermatt和Grächen滑雪胜地。
The Charles Kuonen Hängebrücke, also known as the Europe Bridge, gently swoops across Switzerland's deepest valley, which stretches between the popular ski resorts of Zermatt and Grächen.
它的长度为494米,是世界上最长的行人悬索桥,悬挂在谷底84米处。金属甲板的宽度只有64厘米。
It measures 494 metres long, making it the longest pedestrian suspension bridge in the world, and hangs 84 metres above the valley floor. The metal deck is just 64 centimetres wide.
The bridge opened on 29 July 2017 to relink a hiking trail called Europaweg between the two towns, which was blocked by a rock avalanche in 2010. The tumbling boulders destroyed the existing bridge that measured 250-metres-long and sat 25 metres above ground, and opened just two months before.
Therefore, reconstruction required the new infrastructure to be much taller and longer to avoid similar events in the future. Constructed by Swissrope, the walkway is carried by two ropes with 53-millimetre diameters that are firmly anchored at either end.

Mesh covers the tall angled sides, so as not to obstruct the striking views of the Alpine scenery. Walkers can now cross the valley with ease – as long as they have a head for heights.
Suspension bridges can span further than any other type of bridge. They use tensile cables to support walkways or roadways below, and take many forms and sizes.
Famous examples include the Brooklyn Bridge in New York and the Golden Gate Bridge in San Francisco. The longest in the world is the Akashi Kaikyō Bridge in Kobe, Japan, which carries cars almost two kilometres across the Akashi Strait.
