The significance of Zhongshan Bridge:
As a modern steel frame girder bridge built on the Yellow River and preserved to this day, Zhongshan Bridge integrates use, history and cultural relics. In order to show the vicissitudes of the century-old bridge and highlight the important influence of Zhongshan Bridge on the urban architecture in Lanzhou, in 2004, the Zhongshan Bridge was renovated again, new lights were added, and two squares, south and north, were built at both ends of the bridge. Zhongshan Bridge finally ended its nearly 100-year history of opening to traffic, gloriously withdrew from the mission of transportation hub and officially became a pedestrian bridge.
With the passage of time, more than 10 railway bridges with beautiful appearance, novel structure, advanced technology and extraordinary momentum have been built in Lanzhou city. This ancient railway bridge over the Yellow River is no longer a channel to connect the north and south of the Yellow River. Nevertheless, people still admire and appreciate it, because it is like an epic, which engraves the historical changes of Lanzhou from ancient times to modern times and shows the splendid artistic picture of Lanzhou people.
