Netizens cast doubts on the results of simulation tests purportedly showing the strength of the railings used in the Hong Kong-Zhuhai-Macau Bridge in the event of vehicle crashes.
In a video uploaded by China Central Television (CCTV) over the weekend, a tour bus is seen coming down from a steep slope and hitting the railings at 100 kilometers per hour.
The footage shows the bus tilting to the edge, but the railings are able to withstand the impact and prevent the vehicle from toppling over.
A private car was used for a similar test and the result was the same.
According to CCTV, the field experiments conducted in Beijing provide solid evidence that the bridge railings can withstand the impact from vehicle crashes.
But many Hong Kong netizens pooh-poohed the results, noting the railings used in the actual bridge might not be the same as those used in the tests.
They said officials should instead test the quality of the concrete materials used in the bridge, after 21 people were arrested in May for allegedly faking concrete test results for the mega infrastructure project, which is expected to be completed by the end of the year.
