What is the tallest bridge in the world?

The highest bridge in the world is the Beipanjiang Bridge in Hangrui expressway.

Hangrui expressway Beipanjiang Bridge

The total length of the bridge is1341.4m. The main bridge is a steel truss girder cable-stayed bridge with a span of 720m, ranking second in the world among similar bridges. The height difference between the bridge deck and the valley bottom is 565 meters, which is equivalent to 200 stories high. At present (as of February, 20021year), it is "the first Gao Qiao in the world".

Hangrui expressway Beipanjiang Bridge

20 18, certified by Guinness World Records Co., Ltd., a world record certification institution, the vertical height of Beipanjiang Bridge in Bidu section of Hangrui expressway from the river surface reached 565.4m, and it won the title of "the highest bridge in the world" and was recorded in Guinness World Records. In the same year, the bridge won the Gustav Gold Award at the 35th International Bridge Conference.

The bridge is located at the junction of Du Ge Town, Shuicheng County, Liupanshui City, Guizhou Province, China and Puli Township, Xuanwei City, Yunnan Province. It is a expressway cable-stayed bridge spanning Beipanjiang Grand Canyon, and it is one of the control projects of Bijie-Du Ge section of Hangrui expressway (G56) (Bidu expressway). The bridge is divided into two sections, of which CCCC Second Navigation Engineering Bureau Co., Ltd. is responsible for the construction of BD-T 17 section (Guizhou coast) and Guizhou Highway Engineering Group Co., Ltd. is responsible for the construction of BD-T 18 section (Yunnan coast). The project started construction on 20 12, and was completed and opened to traffic on February 29th, 20 16.

The completion of this bridge is another miracle in the history of bridges in the world. Because the bridge is located in the deep mountain valley of Yunnan-Guizhou Plateau, the valley bottom is 600 meters deep, with frequent geological disasters, changeable weather, strong wind, many clouds, steep terrain and complicated geological conditions, which brings great challenges to the bridge construction. The bridge construction team overcame the difficulties of complex geological environment, serious shortage of hydropower resources and extremely poor traffic conditions. Taking new technologies, new equipment, new processes and new materials as the foothold and focus of technological innovation, they have successively overcome five technical problems, carried out four technological innovations, and adopted high and new technologies such as "smart" concrete and cloud computing for the first time. It is worth mentioning that the bridge construction team pioneered the construction of walking steel truss beam in the world, which not only solved the problem of limited working space in the deep mountain valley area, but also reduced the actual consumption of temporary steel structure design of the bridge by more than 30%, greatly reducing the construction safety risk. This technology won the17th China Patent Award.

The opening of Beipanjiang Bridge on Hangrui Expressway marks the smooth opening of the most difficult-to-control project from Hangzhou, China's east-west artery, to expressway, Ruili. The driving distance from Xuanwei, Yunnan to Liupanshui, Guizhou has been shortened from the past five hours to 1 hour, which has effectively promoted the rapid integration of the border areas of Guizhou, Sichuan and Yunnan into the national expressway network and accelerated the economic and social development in southwest China.

Beipanjiang Bridge on Hangrui Expressway, as a representative of Chinese bridges, said that Beipanjiang Bridge must be mentioned in Chinese bridges. The bridge has become a business card of Guizhou Province and is known as the "Bridge Museum", attracting the attention of the world.
