Yachi Railway Bridge, Railway arch bridge in Qianxi City, China

Yachi Railway Bridge is a steel arch structure spanning 436 meters across the Yachi River at a height of 272 meters from the riverbed. It carries high-speed trains between the Qianxi area and Qingzhen, maintaining 230 meters of clearance above the Suofengying Dam reservoir.

The Yachi Railway Bridge was built as part of the Chengdu–Guiyang high-speed railway, which links the Sichuan capital with Guiyang in Guizhou. The sources give no completion date, so the 2018 figure cannot be confirmed. The bridge crosses the Yachi River between Qianxi County in Bijie and Qingzhen in Guiyang, carrying the line over the Suofengying Dam reservoir.

The bridge demonstrates how modern engineering solves problems in difficult mountain terrain, bringing distant communities closer to larger cities. It represents the effort to connect remote areas with better transportation links.

The best viewing angles come from nearby road sections where you can see the bridge and valley below from different perspectives. Early morning hours usually offer better lighting and clearer skies.

The bridge deck sits 272 m above the riverbed, but because it crosses the reservoir of the Suofengying Dam, clearance over the water is about 232 m. Its 436 m main span makes it one of the longest arch spans in China, and it links Qianxi County in Bijie with Qingzhen in Guiyang.
