Shifting sands: 'flaws' blamed for problems at artificial island for Hong Kong-Zhuhai-Macau bridge
But Highways Department officials insist problem did not put safety in jeopardy
Highways Department officials have admitted flaws in the reclamation process were the reason part of an artificial island that will house facilities for the Hong Kong-Zhuhai-Macau bridge had drifted up to seven metres.
But they insisted that the problem, which involved two circular steel cells each 31 metres in diameter, had been fixed and that safety had not been compromised at the man-made island, which will house immigration facilities for the bridge.

The problem, revealed in media reports this week, was the latest controversy for the massive bridge project, which has long been criticised for its huge cost and environmental impact. It led to fears construction on the bridge - already certain to miss its original target of completion by the end of next year - would be delayed further
Peter Lau Ka-keung, director of the department, (pictured) said the movement was due to the use of a modern, more environmentally friendly form of reclamation, being used in the city for the first time. In it, huge steel cells are sunk into the seabed through the marine mud then filled with debris, eliminating the need for dredging.
"We knew last year that this kind of movement had occurred there," Lau said. "According to our assessment … the situation was still safe. It was not some kind of dangerous situation we needed to inform the public of."
Lau said some movement was "expected and normal". But officers spotted problems with two of the 85 steel cells used.
