On Monday, at approximately 4:30 p.m., INDOT officials announced U.S. 40 at the Clay/Vigo county line would be closed due to the dip, which occurred in a 60-foot long section of the highway.
On Tuesday, INDOT officials, along with officials with the Indiana Department of Natural Resources Division of Reclamation and others, were at the site determining how to handle the situation.
According to officials, at one time, the area was mined. On Tuesday, INDOT officials stated there was possibly a large mineshaft in the area that had recently started settling.
Crew members with INDOT said while there was no estimation as to how long the highway would be closed, because of the heavy traffic on U.S. 40, they believed it would take weeks to repair rather than months.
Fox Surveys and Engineering, Terre Haute, surveyors Charles E. and Charles R. Fox told The Brazil Times the same thing happened approximately 40 years ago.
In addition, they said they had driven over the portion of the highway late last week and had a feeling this would happen.
Both surveyors were on site Tuesday morning providing maps of the area.
Until the area is completely repaired, traffic has been rerouted to State Road 59 onto Interstate-70.
In addition, The eastbound ramp to I-70 at U.S. 41 will be closed from 3-7 p.m., Wednesday, then closed again starting Thursday, possibly in the morning, for two weeks due to the ongoing construction project in the area.
