Zhao Zhouqiao, also known as Anji Bridge, is located on the Weihe River in Zhao County, Hebei Province, across a river more than 37 meters wide. Because the bridge body is all made of stone, it is called "Dashiqiao" locally. Built in the Sui Dynasty from 595 to 605, it was designed and built by the famous craftsman Li Chun, with a history of 1400 years. It is the earliest and best preserved ancient single-hole open-shouldered stone arch bridge in the world today. Zhao Zhouqiao embodies the wisdom and crystallization of ancient working people, and creates a brand-new situation of bridge construction in China. [1] It took Europe about 1397 (some data are about 700 years) to build a similar stone arch bridge.

196 1 was listed as the first batch of national key cultural relics protection units by the State Council, and won one of the top ten city cards in Shijiazhuang on 20 15. It is the first stone arch bridge in China. In the long years, despite numerous floods, wind and rain, ice and snow erosion and eight earthquakes, it stood on the Qingshui River unscathed.
