The sinkhole was about 6 feet by 10 feet wide and at least 25 feet deep.

There aren't many homes on Hill Place in Old Conemaugh Borough, but many drivers use the road as a shortcut to get to Frankstown Road.

One resident said this is at least the third time the road has caved in, and the city's Public Works director said crews have repaired it before. The director said the Bureau of Mining told crews to fill the hole with stone, compact it and repeat the process. But the stone clearly disappeared.

Bill Fisher, who has lived on Hill Place since he was a child, said the sinkhole isn't far from his front door and said there is an old mine there.

"The other day, my wife and myself were sitting in my house and we heard a noise. It wasn't thunder. It was some kind of rumble," Fisher said.

He also said the sinkhole isn't the only thing he's worried about.

"There's a 66-inch water main that runs over top of the mine. What I want to know is what happens if that mine caves in under that water line," he said.

On Wednesday, crews closed the road at both ends until they get more instructions from the Bureau of Mining.
