Transport analysts and legislators are pushing the government to immediately implement interim measures to prevent a repeat of the Tuen Mun disaster.
A senior transport consultant, who declined to be named because of the sensitive nature of the accident and his work for the government, said it would be 'intelligent for the authorities to introduce some measures right away to help prevent another accident of a similar nature'.
'There is an adage that lightning never strikes in the same place twice. But in this case, there are many such high overpasses in Hong Kong and it has now been proven that the regular barriers may be unable to prevent large vehicles, like buses and articulated lorries, from going through them in certain instances,' he said.
Legislator Albert Chan Wai-yip said that, in the long-term, the only solution was to upgrade the barriers.
'But in the interim, the government can put up signs along risky areas, especially the flyovers around Ting Kau and along the cliff side of the Tuen Mun Road, to warn drivers that they should pay attention and be on the alert. In the meantime, the surface of the road could be improved to increase traction,' he said.
A Transport Department spokeswoman declined to comment on whether it was considering interim measures before the police investigation concluded.
