Concessionaires for the Penang bridge and the Sultan Abdul Halim Mu’adzam Shah bridge (also known as the Penang second bridge) have been urged to improve the standard and specifications of the bridge guardrails to prevent further incidents of vehicles plunging into the sea.

The call made by Penang chief minister Chow Kon Yeow comes following an accident in which a SUV plunged into the sea from the Penang bridge following a collision, Bernama reports. He said that the existing guardrails were probably not tall enough to prevent the mishap from occuring.

“In order to stop such incidents from recurring, it is very important for the authorities to further review the specifications and standards of the guardrails to reduce the risks faced by bridge users,” he said.

“Perhaps it (the barrier) is sufficient to prevent ‘normal’ accidents, but the crash on early Sunday morning was a high impact one, which may prove the guardrails to be incapable of preventing vehicles from plunging into the sea, so they need to be reviewed,” he added.

The national news agency said that the latest mishap was the fifth such incident involving the Penang Bridge since 2010. In September 2010, a couple were killed when their MPV crashed into the railings and went off the bridge, while in November 2012 another fatality occured in similar fashion. In 2015, two people were flung from the bridge following separate accidents, one involving a motorcycle and the other a car.
