846 feet high / 258 meters high
4,101 foot span / 1,250 meter span
Dahe Bridge is the third longest span high level bridge in the world with a tower to tower distance of 1,250 meters. The giant crossing is also the second longest span bridge ever built in Guizhou Province, a region of China with several other colossal suspension bridges that include Huajiang, Qingshuihe, Balinghe, Beipanjiang Hukun, Chishuihe Chajiaotan, Malinghe Three and Dimuhe Bridges. Even more amazing the east tower of Dahe Bridge will stand 314 meters in height making it the third tallest suspension bridge tower ever built surpassing Japan's Akashi Kaikyo Bridge but just behind the 328 meter towers of Turkey's Çanakkale Bridge over the Dardanelles Strait and the Zhanggao Yangtze River Bridge.
Several types of bridge were studied including a giant Millau-like cable stayed viaduct and a multi-span beam bridge. Those who are familiar with China's high suspension bridges may also notice that Dahe Bridge is the country's first high level span to have suspended back spans that will give it a more visually balanced look. The main cable will have a span to rise ratio of 9.5:1 with a cable rise of 130.5 meters.
