help Anji Bridge FAQ

Where is the ancient Anji Bridge located?

The Anji Bridge is located in Zhao County, Hebei province, in northern China. It spans the Jiaohe River and was originally constructed during the Sui Dynasty. It is the oldest surviving open-spandrel segmental arch bridge in the world.

Who designed and built the Anji Bridge?

The bridge was designed and built by a craftsman and engineer named Li Chun during the Sui Dynasty. Construction was completed around 605 AD. Li Chun's innovative design has allowed the stone bridge to survive numerous floods, earthquakes, and wars over 1,400 years.

What makes the Anji Bridge an engineering marvel?

The bridge's design utilizes a segmental arch, which is shallower than a traditional semicircle, making it easier for vehicles to cross. Most ingeniously, Li Chun included two small spandrel arches on either side of the main arch. These open spandrels allow floodwaters to flow through the bridge, drastically reducing the water pressure on the structure during heavy rains.

What materials were used to construct the Anji Bridge?

The Anji Bridge was constructed entirely using massive blocks of limestone, procured from local quarries. The builders used iron dovetail joints and molten lead to secure the heavy stone blocks together. This robust construction technique is a primary reason for the bridge's incredible longevity.
