The Anji Bridge (simplified Chinese: 安济桥; traditional Chinese: 安濟橋; pinyin: Ānjì Qiáo; lit. 'Safe crossing bridge'), also known as the Great Stone Bridge or Zhaozhou Bridge, is the world's oldest open-spandrel segmental arch bridge of stone construction. 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. It is considered one of the Four Treasures of Hebei.
