At least 12 workers killed when steel cables failed on Jianzha Yellow River Bridge construction site in Qinghai province. Four workers missing as massive rescue operation continues. Bridge was part of major Sichuan-Qinghai Railway project.

Major Infrastructure Tragedy in Qinghai Province
A catastrophic bridge collapse at a major railway construction site in northwest China has claimed the lives of at least 12 workers, with four others still missing. The incident occurred at the Jianzha Yellow River Bridge in Qinghai province during the early hours of August 22, 2025.
Construction Cable Failure Causes Disaster
According to Chinese state media reports, the collapse was triggered by the failure of one or more steel construction cables supporting the massive bridge structure. The 108-meter-long steel beam gave way, causing the central section of the bridge to plunge 55 meters into the Yellow River below.
Surveillance footage captured the dramatic moment when the middle arch section suddenly collapsed into the river, sending construction materials and workers into the treacherous waters. The bridge was part of the ambitious Sichuan-Qinghai Railway project, designed to be the world's longest double-track continuous steel truss arch bridge at 1.6 kilometers in length.
Massive Rescue Operation Underway
Emergency services launched an extensive search and rescue operation involving 806 personnel, 91 rescue vehicles, 27 boats, a helicopter, and five specialized robots. Six regional hospitals were placed on high alert to receive casualties from the disaster site in Jianzha County.
Rescue teams worked through the night using advanced sonar equipment and underwater drones to locate missing workers in the fast-moving Yellow River currents. The challenging terrain and remote location of the construction site complicated rescue efforts.
China's Infrastructure Safety Record Under Scrutiny
This tragedy marks another serious incident in China's rapid infrastructure development program. Industrial accidents remain relatively common in the country despite government efforts to improve safety standards. The incident has raised questions about construction quality control and worker safety protocols on major infrastructure projects.
The Jianzha Yellow River Bridge was a landmark engineering project, representing China's first railway steel truss arch bridge to span the Yellow River. The collapse represents a significant setback for the strategic railway connection between Qinghai and Sichuan provinces.
