Zhaozhou Bridge was built on the Jiaohe River about 2.5 kilometers away from south of Zhaoxian county. The bridge was constructed in AD 605-616. The bridge was designed by a well-known Chinese mason, Li Chun, and it's made of stone, 50.82 meters long and 10 meters wide, with an unusual arch that is 7.23 meters high with a span of 37.35 meters. The stone railing and columns on the bridge were carved with beautiful dragon and phoenix designs. One of the earliest Chinese arch bridges with a long open-spandrel arch in the middle and two small arches on each side, this bridge occupies an important place in the history of Chinese bridge building and has been of interest to tourists and engineers alike.
