Dahe Bridge is the second longest span high level bridge in the world with a tower to tower distance of 1,250 meters. The giant crossing is also the longest span bridge ever built in Guizhou Province, a region of China with several other colossal suspension bridges that include 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 tallest suspension bridge tower ever built surpassing both Japan's Akashi Kaikyo Bridge and Turkey's Çanakkale Bridge over the Dardanelles Strait.

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.
