At least 12 people died when a steel cable snapped during a tensioning operation on the structure
Four people remained missing on Sunday after a railway bridge collapsed in the northwestern Chinese province of Qinghai, killing 12 people.
The central government has sent a task force to investigate the failure, which occurred on a section over the Yellow River at about 3am on Friday, according to state broadcaster CCTV.
The report said 16 workers were on the Jianzha Yellow River Super-large Bridge carrying out a tensioning operation when a steel cable snapped.
According to media reports, a resident nearby said he was woken by a loud noise “like an earthquake.”
