Crews begin filling huge North Knox County sinkhole

Local News

Crews were out in North Knox County on Wednesday, working to fill the massive sinkhole that opened up the day before.

A Halls resident spotted the growing hole on Greenwell Road and called for help.

“We stopped and it fell out under the roads. So we just called the county so nobody would fall off in it and stopped traffic until they got here,” said Daryl Hill.

The county called on geotechnical engineers to survey the damage. They’re now working to fill the sinkhole with shot rock and concrete.

Engineering and Public Works Director Jim Snowden says the preliminary estimate is it will cost at least $100,000 to fix, which will hopefully be reimbursed if the FEMA declaration of disaster comes through.

As of Wednesday, the hole is about 20 feet deep. It was originally 60 feet, but as the sinkhole grows in diameter, more earth falls in, causing the depth to decrease.

Snowden says it’s still not clear how the hole was formed since the area is not prone to sinkholes.
