On Thursday, INDOT Spokesperson through the Crawfordsville District Debbie Calder told The Brazil Times crews were at the site Wednesday excavating where a crack had formed near the Clay/Vigo county line.
In addition, a 5-8 inch dip formed in the area and as a result, INDOT officials closed a 60-foot long section of U.S. 40 Monday.
Calder said crews planned to patch the crack and reopen the road Thursday afternoon for traffic flow. However, she said the speed limit in the area would be reduced from 55 to 45 mph.
"This is just a temporary fix," Calder said. "The plan is to temporarily have it fixed and get back there in two weeks and try to smooth it out. We wanted to get the roadway back open before the holiday."
Calder said an emphasis on reopening the portion of U.S. 40 was a high priority, particularly with the eastbound exit of Interstate-70 (in Terre Haute) recently being closed.
"We wanted to try to get the roadway opened back up (as soon as possible)," Calder said.
Calder said officials with the Indiana Department of Natural Resources Division of Reclamation have been at the site attempting to determine what caused the crack and dip to form.
Calder added officials explained to her there were no voids found underneath the pavement.
According to officials, the area was mined about 100 years ago. Initially, INDOT officials believed there was possibly a large mineshaft in the area that had recently started settling.
On Tuesday, Fox Surveys and Engineering, Terre Haute, surveyors Charles E. and Charles R. Fox told The Brazil Times the same thing happened in the same area approximately 40 years ago.
