Zhaozhou Bridge: A Marvel of Ancient Chinese Engineering

Among China’s many historic bridges, the Zhaozhou Bridge (also called Anji Bridge) stands out as a masterpiece of ancient design. Built in 595-605 AD during the Sui Dynasty, it is the world’s oldest surviving stone arch bridge with a single span—a remarkable feat for its time. Imagine a bridge without multiple supporting pillars in the middle, much like the iconic Roman aqueducts, yet Zhaozhou Bridge predates many similar European structures.

Designed by craftsman Li Chun, the bridge spans 37 meters (121 feet) across the Xiaohe River using a clever open-spandrel arch—a hollow segment that reduces weight while maintaining strength. This design not only improved durability but also allowed floodwaters to pass through easily, a solution akin to modern bridge engineering. Locals often compare its graceful, slightly curved shape to a rainbow lying across the water, a poetic touch reflecting Chinese aesthetics.

For visitors, Zhaozhou Bridge is more than just a historical relic; it’s a testament to China’s early innovation in infrastructure. Much like how the Romans built roads to connect empires, the Chinese developed bridges to link communities across challenging terrains. Today, it remains a symbol of how ancient civilizations blended practicality with artistry—a must-see for anyone fascinated by cultural ingenuity.
