The second high bridge in the world of Guizhou has been opened to traffic    

The railway construction here is vigorous, and the water activities are not idle. Recently, the world's second high bridge Qingshui River bridge has also been built to drive traffic.

See the Qingshui River bridge site, the Twin Towers of the suspension bridge across the Qingshui River River Canyon, although only a few tens of meters wide, but the steep canyon deep wide, the Qingshui River bridge to reach a total length of 2171 meters, is currently the world's largest single span truss plate with stiffening girder suspension bridge.

The project cost a total cost of 1 billion 540 million yuan, and the bridge floor to the valley bottom is 406 meters and the main span is 1130 meters. In the world's built bridge, its height is only inferior to the four crossing river bridge in Hubei province (560 meters).

The bridge is welded by the plate truss combination technology, and the upper deck steel plate and the lower support truss beam are welded together, and a piece of whole bridge is spliced up again and again. This is the first case in the world similar suspension bridge. In addition, subject to the Karst mountainous terrain, large material vertical lifting, the whole process only like building blocks to break up the whole into parts.

The Qingshui River bridge has been built since August 2013, and it is scheduled to be opened to traffic at the end of 2017. The 35 year old Qingshui River bridge project chief engineer Zhang Mingshan said, two years ahead of schedule due to traffic, he led the "80", "90" team who dares to rush, creatively in the mountainous area using kilometer level large tonnage cable crane bridge and other new technologies, and strictly control mode.

The Guizhou Province, where the Qingshui River bridge is located, is the most concentrated place in the high bridge of China. According to incomplete statistics, seven of the top ten bridges in China are in Guizhou. Guo Junli thinks that Guizhou plateau is the transition from the first step to the third step in China's terrain. There are many mountains and canyons. The increasingly dense highway has made the height of Guizhou bridge high.
