Revolutionary leader Sun Yat-sen once suggested that

an underwater tunnel should be built to connect the railways in Nanjing

, but his dream was not realized for about 100 years. In 1929, Sun’s casket was transpor

ted to Pukou district along the Tientsin-Pukow Railway before being ferried to downtown Nanjing.

In 1930, John Alexander Low Waddell, a 76-year-old Canadian who was a

traffic consultant to the Chinese government, said the Yangtze in Nanjing was too deep and

was flowing too fast to construct a bridge, according to the Academy of Sociology.

The government launched large-scale investigations in 1936 and 1946 before dropping the pla

n. In 1956, the State Council, China’s Cabinet, proposed constructing the Nanjing Yangtze River Bridge.

To test the bridge’s load-bearing capacity, Xu Shiyou, who comma

nded the Nanjing Military Region, ordered an armored regim

ent to drive 118 amphibious tanks on the newly built structure at 8 am on Sept 25, 1969.
