With so many bridges crossing the Yangtze and Jialing rivers in the urban area, Chongqing is sometimes known as the 'Bridge Capital of China'. The first important bridge in urban Chongqing was the Niujiaotuo Jialing River Bridge, built in 1958. The first bridge over the Yangtze river was the Shibanpo Yangtze River Bridge (or Chongqing Yangtze River Bridge) built in 1977.
