在重庆武隆大洞河大峡谷，有一座高达300余米的悬空铁索桥横跨于峡谷上方，令人震撼不已！而更让人惊奇的是，这座铁索桥并没有桥墩，也没有一根斜拉绳，仅靠4组绳索提供水平拉力，竟然能承受起40多吨的货车通行，设计独特、惊险震撼。
China is famous for its impressive infrastructure (基础设施), from suspended “river highways” to surprising overpasses.
中国以其令人印象深刻的基础设施而闻名，从悬空的“内河高速公路”到令人惊讶的立交桥。
For the past couple of years, videos of heavy construction vehicles crossing a narrow bridge suspended about 300 meters above the Dadong River Gorge in Chongqing have constantly been popular on social media, leaving people wondering about its safety. Although it spans 240 meters, this suspension bridge (吊桥) has no towers or base for support, relying only on four steel cables to support vehicles up to 45 tonnes in weight. It’s only wide enough for one vehicle to cross, and despite featuring safety nets on each side, one wrong move can spell disaster. It’s tricky enough to drive the vehicle in normal conditions, but imagine having to do so on a particularly windy day.
在过去的几年里，重型施工车辆通过重庆大洞河峡谷上方约300米的狭窄桥梁的视频在社交媒体上不断流行，让人们怀疑它的安全性。尽管这座悬索桥跨度240米，但它没有塔或基座作为支撑，仅依靠四根钢索来支撑重达45吨的车辆。它的宽度只够一辆车通过，尽管两边都有安全网，但一个错误的举动可能会带来灾难。在正常情况下驾驶这辆车已经够棘手的了，但想象一下，在一个特别有风的日子里驾驶车辆通行。
Luckily, the Dadong River Gorge suspension bridge in Chongqing’s Wulong District is a temporary project designed to facilitate the construction of an even more impressive piece of infrastructure, Shuangbao Bridge. When completed, it will be the world’s largest double-arch bridge, stretching over both the Dadonghe and Xiaohegou Rivers. But in order to build this structure, workers needed a way to reach the small mountain that would end up supporting its center arch abutments (拱桥台). And that’s when they came up with the idea of a temporary suspension bridge.
幸运的是，重庆武隆区的大洞河峡谷悬索桥是一个临时项目，旨在促进建设一个更令人印象深刻的基础设施——双堡特大桥。建成后，它将成为世界上最大的双拱桥，横跨大洞河和小河沟。但为了建造这个结构，工人们需要一种方法来到达这座小山，最终支撑它的中心拱台。就在那时，他们想到了修建一个临时吊桥的主意。
Stretching 240 meters across the west side of a massive gorge, the so-called “world’s scariest suspension bridge” is 12 meters wide, but only has a track wide enough for one vehicle to pass at a time. Technically, that is not a problem, as it is only used by trucks and construction machinery working on Shuangbao Bridge, but that doesn’t mean crossing it is easy.
这座被称为“世界上最恐怖的悬索桥”横跨一个巨大峡谷的西侧，全长240米，宽12米，但其轨道宽度只够一辆车通过。从技术上讲，这不是问题，因为只有在双堡特大桥上工作的卡车和建筑机械才会使用它，但这并不意味着通过它很容易。
