The length is 1341.4m (0.8 mile) with a main span of 720m (0.45 mile). "The height of the bridge tower on the Guizhou side and the Yunnan side is 269 meters [883'] and 247 meters [820'], the vertical distance from the bridge surface to the river surface is 565.4 meters [1,855'], and the vertical distance from the top of the bridge tower to the river surface is 740 meters [2,248']. There are 112 pairs of 224 cable stays in the bridge." In addition to World's Highest, as of 2018, it "was the world's largest cable-stayed bridge with steel truss beams." (I've noticed that most cable-stayed bridges use box girder decks.) It shortened the travel time between Xuanwei and Shuicheng from more than four hours to less than one hour. Highway Engineering Discoveries posted World Highest Bridge The Duge Bridge , also called the Beipanjiang Bridge, is a four-lane cable-stayed bridge on the border between the provinces of Guizhou and Yunnan in China.As of 2021, the bridge is the highest in the world, with the road deck sitting over 565 metres (1,854 ft) above the Beipan River. The bridge is part of the G56 Hangzhou–Ruili Expressway between Qujing and Liupanshui. The eastern tower measures 269 m (883 ft), making it one of the tallest in the world.

[This web page has many photos, including a sequnce that shows how a travelling gantry built the deck from truss segments.] |

| Diagram via HighestBridges "Today the Province of Guizhou is home to more high bridges then every other country on earth combined. By 2030 Guizhou will have more then 1,000 bridges over 100 meters high as measured from the road or rail deck to the water. Compare that with Italy which has the world’s second greatest number of high bridges with only 60 spans exceeding 100 meters in height. Of the world’s 50 super-high spans that exceed 300 meters from deck to water, all are in China except for 3." |

It is so high because "the designers kept having to move the final location of the bridge higher and higher to avoid caves and cracking in the karst mountains at either side of the valley." (One of the sources said that the river carved the canyon in a limestone mountian. I learned while studying Hales Bar Lock & Dam that limestone mountians do not make good foundations.) |
