• At least 12 people confirmed dead in a bridge collapse in northwest China.
• Four additional workers remain missing after the accident.
• The bridge was part of the Sichuan-Qinghai Railway and represents a major engineering achievement.

At least 12 workers have died and four others are missing after a bridge under construction collapsed into the Yellow River in northwest China. The incident occurred during a tensioning operation when a steel cable failed, according to state media reports. Sixteen individuals were present on-site at the time, including project managers and workers. The bridge was a significant engineering project, being the world's largest-span double-track continuous steel truss arch bridge, also noted for being the first railway arch bridge over the Yellow River, as reported by Channel News Asia, CBS News, and India Times.

Rescue operations have mobilized hundreds of emergency responders, utilizing boats, helicopters, and even robots in the search for the missing workers. Footage from the scene shows a significant portion of the bridge missing, emphasizing the scale of the disaster, as indicated by Channel News Asia and CBS News. Industrial accidents of this nature are not uncommon in China, often attributed to lax safety regulations, as noted in several reports including India Times.

This tragic event calls attention to the ongoing concerns regarding construction safety standards in China, which have been highlighted in previous incidents such as a cave-in at a railway site in Shenzhen last December where 13 workers went missing with no survivors reported, according to CBS News and India Times.
