According to reports from Xinhua News Agency and Jimu News, the steel cable unexpectedly snapped at approximately 3:00 AM, resulting in the fall of a steel arch and the tensioning platform. A total of 16 personnel – 15 construction workers and one project department head – were affected by the collapse. Initial assessments reveal a structure approximately tens of meters in length plunged into the Yellow River.
The Jianzha Yellow River Super Bridge, initiated in 2023, is a landmark project touted as the “world’s largest double-line railway continuous steel truss arch bridge.” The construction is being led by the China Railway Bridge bureau Group Corporation, a subsidiary of the state-owned China Railway Group.
Expert Analysis Points to Structural Failure
professor Peng Weibing of Zhejiang University of Technology’s School of Civil Engineering, analyzing on-site images, suggested the accident stemmed from a widespread failure of connections. He indicated the majority of the main span and side span buckles, linked to the unilateral sling tower, had fractured, leading to the bridge deck’s detachment and the subsequent fall of workers into the river. The damaged section is estimated to be 80 to 100 meters in length.
A Pattern of Safety Concerns
This incident marks the second notable engineering failure linked to a China State-owned Railway Group subsidiary this year.In March,a building of the Audit Office in Bangkok,Thailand,collapsed during an earthquake in Myanmar,resulting in nearly 100 casualties. The China Railway 10th bureau oversaw the construction of the 30-story structure, which suffered catastrophic damage.
Furthermore, concerns over engineering quality have surfaced in Europe, triggering public backlash. Last year, a ceiling collapse at the Novi Sad Railway Station in Serbia, a project involving China Railway and China Communications Construction Corporation, resulted in 16 fatalities and sparked protests over alleged corruption and negligence. Serbian authorities arrested 11 individuals, including a former minister and a railway executive, on charges of financial irregularities and enabling illicit profits for the chinese companies.
