Zhengxin Yellow River Bridge, Road-railway bridge spanning the Yellow River between Huiji District and Yuanyang County, China

Zhengxin Yellow River Bridge is a two-level structure that carries both road traffic and trains across the wide waterway on separate decks. The bridge features sturdy steel and concrete construction with multiple supporting piers anchored deep in the river bed.

Completion of the bridge in 2012 represented a major milestone for the Beijing-Guangzhou High-Speed Railway, which transformed regional connectivity across central China. The project was part of broader infrastructure development that reshaped how people and goods move through Henan Province.

The bridge's name changed from Zhengzhou Yellow River Road-Railway Bridge to Zhengxin, linking Zhengzhou and Xinxiang. It was Henan's first combined road-rail crossing of the Yellow River and the second such bridge on the river after the Binzhou Yellow River Bridge in Shandong.

The bridge has clearly marked lanes for cars and trucks with toll collection points at designated plazas. Pedestrians cannot cross on foot as the structure is strictly for motor vehicles and train traffic.

The bridge's combined road-rail section is 9.177 km long, which its builders cite as the longest such structure in the world. It was Henan's first bridge to carry both a highway and a railway over the Yellow River, and only the second of its kind on the river after the Binzhou bridge in Shandong.
