A flyover being built on Tai Ho Road in Tsuen Wan was damaged when a lorry driver who forgot to lower the crane on his vehicle slammed into a metal structure at the bottom of the flyover, which has a height clearance of 4.7 meters, the Hong Kong Economic Journal reports.
Luckily, no one was injured in the accident, which happened outside the Nina Tower at around 10 a.m. on Tuesday.
Steel girders and other debris crashed down on the windshield of an oncoming bus behind the lorry, Apple Daily reported.
All vehicular lanes on Tai Ho Road towards the Tsuen Wan Ferry were temporary closed, causing detours of several bus routes and traffic chaos for up to six hours.
The 64-year-old lorry driver, surnamed Wong, called the police about the accident. The flyover’s building contractor also sent staff to measure the height of the crane on the lorry, which was later found to be 4.7 meters.
Under existing laws, the height of the crane on a lorry in motion should not exceed 4.6 meters. Violators could face a fine of HK$5,000 and three months’ imprisonment.
Ng Kwok-wing, chairman of the Hong Kong Professional Hoisting Engineering Association, said the lorry driver might have failed to fully retract the crane before driving the vehicle.
There are standard operation guidelines to ensure that a crane is fully retracted before the vehicle is driven, Ng said.
A spokesperson for Chinachem Group, the contractor for the flyover, said the net clearance of the structure is 4.8 meters, but declined to comment on the accident in view of the ongoing police investigation.
