A section of Upper Changi Road East caved in on Thursday morning causing a tipper truck to collapse into the road. The accident happened about 50m away from a construction site for the upcoming Downtown Line 3. We look at some recent cases of sinkholes which had appeared in different parts of Singapore, and what could have caused the cave-ins.

1. Keppel Road, Jan 30, 2013

What: A sinkhole appeared near a junction along Keppel Road towards Ayer Rajah Expressway during the morning rush-hour traffic. A driver, who thought it was a puddle, drove his car into it. He estimated the hole to be around 2m wide and 0.5m deep.

Why: The sinkhole was possibly caused by a pipe leak.
