Design a guidebook for Zhao Zhouqiao in about 80 words.

Hello, welcome to Zhao Zhouqiao, Zhao County, Hebei Province. I am your tour guide.

The world-famous Zhao Zhouqiao is located on the Weihe River, 2.5 kilometers south of Zhaoxian County, Hebei Province, and only 45 kilometers southeast of Shijiazhuang City. Zhao Zhouqiao is the first stone arch bridge with open shoulders in the history of bridges in the world. It was built during the reign of the Sui Emperor (58 1-60 1) and has a history of 1400 years.

Zhao Zhouqiao, also known as Anji Bridge, has a total length of 64.40 meters, a vault width of 9 meters, a width of 9.6 meters at both ends, a span of 37.38 meters and an arch height of 7.23 meters. The bridge is beautifully built and beautifully shaped. The whole body is composed of huge granite stones, and 28 independent stone arches are laid side by side vertically, forming a single-hole isolated bridge across the river bank. There are two small arches on the shoulders at both ends of the bridge arch. These arches reduce the weight of the bridge, and at the same time play a role in reducing the impulse of running water and accelerating the flow of flood. The design is very scientific and reasonable. At that time, the use of this open-shouldered arch was the first time in the history of bridge construction in the world, which was a pioneering work.

Because Zhao Zhouqiao is a masterpiece, people have said that this bridge was built by the immortal Lu Ban for thousands of years. In fact, Zhao Zhouqiao was built collectively by Li Chun, an outstanding craftsman of the Sui Dynasty in China, which has been recorded by many masons in history. Zhao Zhouqiao has become a rare and beautiful scenery in the history of bridge architecture, and has been listed as a national key cultural relics protection unit by the state.

All right, tourists, Zhao Zhouqiao is over. Thank you for your support!
