Adelaide sinkhole downgraded to pothole

A sinkhole has swallowed the bottom part of a truck on an Adelaide street.

Police confirmed the incident happened in Broadview, in Adelaide's northern suburbs, at around 10am this morning.

Photographs show the truck's rear axle completely underground and its front right wheel off the ground.

Con Tsacos, who was working nearby when the truck was engulfed by the pot hole, told 891 ABC Adelaide that it is lucky the truck didn't roll over onto its side.

"I could just hear a rumble, a bang, crash, and turned around and I could see this truck falling over," Mr Tsacos said.

"[It happened] relatively quickly, then it sort of took its time to fall down. I've never seen anything like it, unbelievable."

The truck is operated by the City of Prospect.

Luckily, nobody was injured.
