TRIGG COUNTY, Ky. (KFVS) - A section of KY 126/Cobb Road in northern Trigg County reopened to traffic between the 4 and 5 mile markers.

That was where a sinkhole was found under the road on Wednesday afternoon, September 29.

According to the Kentucky Transportation Cabinet, the sinkhole was about 2 miles west of the Cerulean community and a little less than a mile east of the Trigg-Caldwell County line.

A contract mowing crew was working along the right-of-way on Wednesday afternoon when one of the tractors broke through the surface. The crew found a hole created by the tractor at the edge of the pavement was a sinkhole initially estimated to be about 8-feet deep.

KYTC District 1 engineers went to the site on Thursday and determined the hole extended about 18-feet below the road.

The area was excavated.

Engineers determined water had been filtering out around several large rocks in the bottom of the sinkhole, carrying material with it.

KYTC said the area was backfilled with rock to allow it to drain without eroding under the road. Engineers will be checking the site regularly for several weeks.

Once the area has had time to settle, an asphalt cap will be placed on the site in a few months.
