The Jianzha Yellow River Bridge (尖扎黄河特大桥) is an under-construction steel railway bridge of the Sichuan–Qinghai railway across the Yellow River located on the border of Jianzha county, Huangnan prefecture and Hualong county, Haidong city, both in Qinghai, China.[2]
The bridge is to be 1,596.2 m (5,237 ft) long, with a span of 366 m (1,201 ft).[1][3]
The bridge is being constructed by China Railway Major Bridge Engineering Group, and was scheduled to be completed by the end of August 2025.[3]
When completed, it will be China's first railway continuous truss arch bridge across the Yellow River and the world's largest double-track continuous steel truss arch bridge.[2]
