Stamp Issue : 1962-05-15 

Zhaozhou Bridge also known as Anchi Bridge is the world's oldest open-spandrel stone segmental arch bridge cross the Jiao River, about 50 m long with a central span of 37.37 m. It stands 7.3 m tall and has a width of 9 m. Credited to the design of a craftsman named Li Chun, the bridge was constructed in the years 595-605 during the Sui Dynasty (581–618). Located in the southern part of Hebei Province, it is the oldest standing bridge in China. In the next 1400 years, the bridge survived at least eight wars, ten major floods and numerous earthquakes, the nearest of which being the 7.2 degree Xingtai Earthquake in 1966. Yet, the support structure remains intact and the bridge is still in use. Only the ornamental railings have been replaced every few hundred years.
