At the junction of Guizhou and Yunnan stands the U-shaped bottomless Beipan River Grand Canyon, where Beipanjiang Bridge spans the Beipan River at a height of 565.4 meters above the water.

As an important project of the Hangzhou – Ruili Expressway (National Expressway G56), the Beipanjiang Bridge has a total length of 1,341.4 meters and the largest span of 720 meters. It is connected to Duge Town, Shuicheng District of Guizhou Province in the east and Lalong Village, Xuanwei City of Yunnan Province in the west. The vertical distance between the bridge deck and the river surface is 565.4 meters. When it was under construction, it was crowned as the world’s highest bridge and the steel-truss cable-stayed bridge with the world’s largest span.

Unprecedentedly, the construction team applied the 500E high-quality anti-seismic steel bars, and several advanced technologies such as incremental launch and main girder plate-truss composite structure to the construction of the bridge. Both small and large cranes were used for installation within 0.5 millimeters of precision which is equivalent to 1/4 of the thickness of a coin. The entire bridge has used more than ten thousand steel components which weight nearly thirty thousand tons.

The precision, speed and quality of China surprised the world again. In June, 2018, the Beipanjiang Bridge received the Gustav Lindenthal Medal, the highest award of the 35th International Bridge Conference which is known as the “Nobel Prize” in the bridge industry, and became a masterpiece of this era.

This is a bridge of chances and happiness. Since the completion of the Beipanjiang Bridge, the four-hour drive from Xuanwei, Yunnan to Liupanshui, Guizhou has been shortened to one hour. It marks the connection of the last break point of the “Five Vertical Expressways and Seven Horizontal Expressways” expressway network of China, and the rapid integration of the junction of Guizhou, Yunnan and Sichuan in the national expressway network. It also serves as a fast access of export and tourism of Guizhou, making itself the most unique and iconic cultural symbol of Guizhou.
