Anji Bridge
open-spandrel arch bridge in Hebei Province, China

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.
Name and location
The bridge is also commonly known as the Zhaozhou Bridge (simplified Chinese: 赵州桥; traditional Chinese: 趙州橋; pinyin: Zhàozhōu Qiáo), after Zhao County, which was formerly known as Zhaozhou (趙州). Another name for the bridge is the Great Stone Bridge (simplified Chinese: 大石桥; traditional Chinese: 大石橋; pinyin: Dàshí Qiáo). It crosses the Xiaohe River (洨河) south of the town of Zhaoxian, in Zhao County, approximately 52 kilometres (32 mi) southeast of the provincial capital Shijiazhuang. It is a pedestrian bridge and is currently open to the public.
In English literature, it is also referred as Chiao Shui Bridge, after the river it crosses.

Why this record matters
The phrase “open-spandrel arch bridge in Hebei Province, China” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated May 1, 2026. The linked authority identifier is Q551446. Authority coordinates are 37.720, 114.763. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
