Zhao Zhouqiao is located in Zhao County, Shijiazhuang City, Hebei Province, China. Zhao Zhouqiao was built in the Sui Dynasty, designed and built by Li Chun, and later named Anji Bridge by Song Zhezong. It is the largest span and the most intact single-hole open-shouldered stone arch bridge in the world, with unique construction technology and high scientific research value, which occupies an important position in the history of bridge construction in China.

Where is Zhao Zhouqiao?

There is a very important reason why Zhao Zhouqiao has been enduring for thousands of years. Li Chun, a craftsman, chose the site of Zhao Zhouqiao in the Weihe River coarse sand ground, because using coarse sand as the foundation can improve the bearing capacity of the bridge and ensure the stability of the bridge. Modern investigation proves that the stratum distribution in the bridge site area of Zhao Zhouqiao is stable, and it is an ideal place to build a long-span single-span bridge, even natural disasters such as earthquakes and floods will not be destroyed.

Zhao Zhouqiao is a single-hole secant circular stone arch bridge with open shoulders. Because there are two small holes in the shoulders at both ends of the bridge, it is also called "open-shouldered bridge". The bridge is about 5 meters long, 9.5 meters wide, 2 to 2.5 meters deep in foundation, and the abutment thickness is 1.549 meters, so the structure is extremely stable.

The origin of Zhao Zhouqiao's name

Zhao Zhouqiao has had many names since its establishment. Zhaozhou Dashiqiao is a common name of local people, because Yongtong Bridge was built on Qingshui River outside the west gate of Zhaozhou City, which is later than Zhaojun River Stone Bridge, but they are similar in architectural structure and style, but the latter is smaller and the two stone bridges are closer, so they are also called Zhaozhou Dashiqiao and Zhaozhou Xiaoshiqiao. Zhao Zhouqiao is named after a local place name. In the second year of Tianbao in the Northern Qi Dynasty, Yanzhou was changed to Zhaozhou, and the name of Zhaozhou began here. 590 years after the completion of Zhaojun River Stone Bridge, Emperor Song Zhezong named it Anji Bridge and renamed it.
