Nanjing Yangtze River Bridge by karen75
This is a very important bridge in Nanjing. The bridge was constructed from 1961 - 1968 and consists of a highway on the top level and a railway bridge on the bottom level. It spans a length of 6,772 metres (22,212 feet) which is approximately four miles long. There is a lookout tower located on the bridge and inside is a tall statue of Mao Zedong.
