Cause of sinkhole on I-80 in NJ revealed

Mineshaft. 40-foot deep.


The sinkhole was caused by the collapse of an abandoned mineshaft, according to the New Jersey Department of Transportation.

There are several abandoned iron mines in the area dating back to the 1800s, according to an official New Jersey state geology information map. That includes the old Mount Pleasant iron mine, which operated about 25-50 feet away from the sinkhole in Wharton, according to state records.

Jim Hill, the owner of the nearby Knotty Pine Pub in Wharton, said there are mineshafts all over the area and that sinkholes have popped up for years.Wharton is within a stretch of Northern New Jersey that was once a mining hub — home to 445 mines that are now abandoned.

“The underground is basically Swiss cheese,” said William Kroth, the executive director of the Sterling Hill Mining Museum.

The town is chockfull of mine shafts. Sure they filled in a few, but not by far, still a number of them open up occasionally.

I wonder where Joplin stands on it.

Florida is the number one state for sinkholes. I was looking at it and there are sinkholes on the barrier reef!

mineshafts collapse. The big thing was if they collapsed on a building site (which they did, a church was building, and encountered a mineshaft, there went the 3rd floor, so the building ended up being only two floors instead of 3. They still finished the building there too, which surprised me, but they did say they poured a whole lot of concrete into the hole, the now 2 story building vs. the planned 3 story. I am sure that they still continue to have mineshafts collapse down there (in Joplin).

Scene depicting him growing up in Butte, MT and a car honking at him for being in the street, then the car disappearing into a sink hole and down a mine shaft.

Yeah, the extraction industry leaves us with a whole lotta holes.

in Franklin, N.J. My. original thinking was that the mine shaft was abandoned and not made secure. Maybe it was a sinkhole that opened up. She was walking home at dusk, 1890's when there was no electric lighting.

Thanks for sharing that, 3Hotdogs, even though it is a sad story. Truth is, harm could come to any one of us walking in that area or even in an area where there's bedrock. I am sorry that had to happen to your family.

On another note, I understand at least one lane is now open and the sinkhole is patched.
