Three people were killed and two others injured when a raised section of a major highway in eastern China suddenly collapsed on top of their vehicles on Thursday evening. The casualties were occupants of two vehicles crushed by the falling flyover on China National Highway 312 in the city of Wuxi, Jiangsu province, soon after 6pm, state broadcaster CCTV reported on Friday. The third vehicle parked on the road was also crushed but there was no one inside. Three cars and two trucks were on the section of flyover when it collapsed, Shanghai-based news site ThePaper.cn reported on Thursday. More than 500 military police and traffic police officers were sent to the scene, while three excavators were dispatched to clear up the rubble. A preliminary investigation found that the structure failed under the weight of overloaded freight trucks on the flyover at the time, CCTV reported. Footage of the incident circulating on social media showed the moment the flyover collapsed. Traffic police had reportedly warned drivers of freight vehicles not to use the flyover, prompting internet users to question why overloaded vehicles were using it. “Lots of people have been reporting this for years, how come no one dealt with it in all that time?” one commenter wrote, attracting more than 40,000 likes. “The dark turning point of the Chinese economic miracle. The brilliant city turns into a hellish nightmare in a moment,” tweeted US-based Chinese commentator Weiping Qin in a caption to the video.

A 32-year-old man surnamed Gu from Wuxi and a 39-year-old surnamed Li from the nearby city of Xinghua were questioned by police after commenting on a photo of the rescue operation. In the comments, Gu and Li allegedly falsely claimed the Wuxi police chief was wearing a Swiss luxury watch. Gu and Li confessed that they made false comments about the photo in different WeChat groups to attract attention, according to the police statement.
