It is the oldest and best-preserved long-span single-span flat-arc stone arch bridge with open shoulders in the world. The completion of the bridge has condensed the wisdom and crystallization of the working people of the Han nationality, created a brand-new situation of bridge construction in China, and was praised by Liang Sicheng as "a unique project in China".

It spans the north and south banks of Lianshui, and was built from the first year to the eleventh year of Daye in Sui Dynasty (605-616), and was supervised by craftsman Li Chun. It has a history of 1400 years. Because the bridge body is made of stone, it is commonly known as "Dashiqiao". It took Europe about 1397 (some data are about 700 years) to build a similar stone arch bridge.

This bridge is a hollow circular-arc stone arch bridge, the earliest and best-preserved giant stone arch bridge in the world. Zhao Zhouqiao is the first open-shouldered stone arch bridge to be selected into the world record association Book of World Records, which is the best in the world. Zhao Zhouqiao, Cangzhou Iron Lion, Dingzhou Kaiyuan Temple Pagoda and Zhengding longxing temple Bodhisattva are called "Four Treasures of North China" by Hebei folks.

The bridge is 50.82 meters long, 37.02 meters across, 7.23 meters high and 9.6 meters wide at both ends. The design of the bridge completely conforms to scientific principles, and the construction technology is even more ingenious. Zhang said in the Tang dynasty that it was "made strangely, and people don't know why." The characteristics of this bridge are: (1) The whole bridge has only one large arch, which is 37.4 meters long, and it was the longest stone arch in the world at that time. Bridge opening is not an ordinary semicircle, but like a bow, so there is no steep slope on the road above the big arch, which is convenient for horses and chariots to get up and down. (2) A big arch has two small arches on each shoulder. This is a very creative design, which not only saves stones and reduces the weight of the bridge, but also increases the water flow in bridge opening and reduces the impact of floods on the bridge when the river surges. At the same time, add an arch on the arch to make the bridge more beautiful. (3) The large arch consists of 28 arch rings, just like so many arch dragons with the same shape together, making an arc-shaped bridge opening. Each arch ring can independently support its weight. If one arch ring is broken, the other arches will not be affected. (4) The structure of the whole bridge is symmetrical, which is in harmony with the surrounding scenery; The stone pillars and slabs on the bridge are also beautifully carved. Zhang Kun of the Tang Dynasty said that looking at the bridge from a distance is like "the clouds rise at the beginning of the month, and Changhong draws a stream". Zhao Zhouqiao's superb technical level and immortal artistic value fully show the wisdom and strength of the working people in China. Li Chun, the main designer of this bridge, is an outstanding craftsman. In the inscription on the bridge head, there are two small arches with different spans on each shoulder of the arch ring, that is, the open-shouldered arch. This is a creation in the history of bridge building in the world (called full-shoulder arch or solid-shoulder arch without small arch), which makes it more beautiful than solid-shoulder arch, which can not only reduce the dead weight of the bridge, save materials, but also facilitate flood discharge and increase aesthetics. Zhao Zhouqiao's design concept and technology are superb. Zhang Kun of the Tang Dynasty said that looking at this bridge from a distance is like "Yun Qi in the early month, Changhong drinking the stream".
