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.

该桥于2017年7月29日开放，重新连接两座城镇，称为欧洲大桥，两座城镇于2010年受到岩石雪崩侵袭，滚滚的巨石摧毁了原有的桥梁，这座两个月前才开放的桥梁测量长度为250米，位于地面以上25米处。

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.

因此，重建桥梁需要更高更长的基础设施，这样才能避免将来发生类似的事件。因此，新桥梁由Swissrope建造，人行步道由两根直径53毫米的绳索承载，两根绳索牢固地固定在山谷两端。

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.

网格扶手成角度地放置，以免挡住阿尔卑斯山的壮观景色。只要没有恐高症，步行者都可以轻松地穿越山谷。

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.

比起其他类型的桥梁，悬索桥的跨度最大，设计师使用张拉索来支撑下方的步道，并采取了多种不同的形式和尺寸。

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.

悬索桥的典型案例包括纽约的布鲁克林大桥和旧金山的金门大桥。世界上最长的悬索桥是位于日本神户的明石开桥，长度约两公里。

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.
