In the Qing Dynasty, the first railway bridge of the Yellow River was built by German businessman Keyus under the technical guidance of American Man Baoben and Dro. Formerly known as "Lanzhou Yellow River Railway Bridge", 1942 was changed to "Zhongshan Bridge". 1954, Lanzhou Municipal People's Government renovated and strengthened the iron bridge, adding five curved steel arch beams, which made the iron bridge look durable and magnificent.

1937 after the outbreak of War of Resistance against Japanese Aggression, the Japanese invaders occupied North China, East China and South China, blocked most of China's seaports, and the northwest and southwest became the strategic rear areas related to the overall situation of the Anti-Japanese War. As a transportation hub in northwest China, most of the aid materials imported by the Soviet Union from Xinjiang arrived in Lanzhou through Gan Xin Highway, and then were transported to the anti-Japanese front through Xilan Highway.
Zhongshan Bridge is the only bridge that crosses the Yellow River and connects two roads on the east-west passages of Ganxin and Xilan. The unprecedented military and economic status has become a key bridge to provide logistical supplies for War of Resistance against Japanese Aggression.
During his stay in War of Resistance against Japanese Aggression, Zhongshan Bridge was not only an important position for China soldiers and civilians to fight against Japanese invaders, but also a symbol of the indomitable spirit of Lanzhou people. On this bridge, an endless stream of camel teams and cars continuously transported countless rations, weapons and ammunition to the front line of the Anti-Japanese War. This iron bridge, originally designed for the passage of horses and chariots, has made an indelible contribution to War of Resistance against Japanese Aggression.
