Recently, a construction bridge at the construction site of the Shuangbao Super Bridge on the Chongqing Wulong section of the Yuxiang Expressway has become popular on the Internet. The suspended chain bridge spans a 300-meter-high canyon with a span of 245.52 meters. Trucks driving on the 4.3-meter-wide bridge are like walking on a tightrope.

According to reports, this kind of suspension bridge construction is not common in road bridge construction, but under the local terrain conditions, it is necessary to build this bridge.

The Yuxiang Expressway has long double-track lines, many long tunnels, and many high-pier and long-span bridges, with a bridge-to-tunnel ratio of over 80%. Among them, the Shuangbao Bridge has a total length of 810 meters and is currently the largest double arch bridge under construction in the world.Editor/Ma Xue
