Iron Bridge

Built on the Yellow River at the foot of White Pagoda Hill near Lanzhou, this was the first bridge on the Yellow River. During the fourteenth century, there was a floating bridge here, called Zhenyuan Bridge, which served as an important link on the Silk Road. The floating bridge was replaced in 1907 by the present iron bridge, which was reinforced in 1954.
