Jiujiang Yangtze River Bridge is completely designed and built by China, and the materials are all domestically produced (there is doubt here), creating more than a dozen firsts in the history of Chinese bridges. After the completion of the Nanjing Yangtze River Bridge in 1993, it became the longest road and railway dual-use bridge in China, of which the main river trough of the bridge is 216 meters wide, ranking first in China. Most of these records have been surpassed by later generations, but one record may never be broken the bridge took 20 years to be fully built (the railway bridge opened to traffic) and 23 years to be completed.
