Explore the wonders of Xiangxi: Aizhai Extra-large Suspension Bridge.

In Jishou City, Xiangxi Prefecture, Hunan Province, there is an amazing architectural wonder - Aizhai Extra-large Suspension Bridge. The Aizhai Bridge, which started construction in 2007 and opened to traffic in March 2012, is a large bridge that crosses the Dehang Grand Canyon on the Baomao Expressway (G65). This steel truss single-span suspension bridge has a main span of 1,176 meters, a considerable bridge width, and an astonishing height from the bridge deck to the bottom of the canyon, reaching 355 meters. During the construction of the bridge, it created "four world firsts": the span between the two cable towers of the bridge is 1,176 meters, the world's first span across the canyon; the first to adopt a completely separate structure design of the tower and beam; the first to adopt a rock anchor cable structure and use carbon fiber as prestressed reinforcement; the first to adopt the "track cable sliding method" to erect steel trusses. It shows the courage and courage of human beings to conquer natural dangers with engineering technology. It is a model of the perfect combination of bridge architecture and natural landscape. The whole bridge uses a total of 470,000 bolts, which is shocking.
