SINGAPORE - A long vehicle attempting to execute a right turn onto Woodlands Centre Road nearly toppled over, spilling its cargo of heavy metal parts on the road on Wednesday (Oct 7).

The incident happened at a T-junction near the An-Nur Mosque at around 3pm.

Bank executive Huang Zhixiong, 24, was at work nearby when he heard a "crash like thunder" and went outside to investigate.

"The whole road was blocked by the long vehicle, which had listed slightly to its left. It appeared to have lost balance as it was turning right," said Mr Huang.

"The entire road was blocked as there were metal parts on the road and vehicles had to diverted. It was lucky the long vehicle had not toppled over."

Pictures sent in by Mr Nizam Razak at about 7.30pm showed workers helping to remove the metal beams from the road.

As of 8.30pm, the road was still closed and the vehicle's company was still in the process of clearing up the site.

It is understood that no one was injured.
