Drivers traveling along the section of I-75 S. through Campbell County, which was repaired last year, might have noticed a depression throughout that section of roadway.

10News contacted the Tennessee Transportation Department, and according to TDOT spokesperson Mark Nagi, this type of settlement is typical.

TDOT said the repaired roadway is responding well to the roadwork and will eventually even out. During the roadwork, crews laid an enormous amount of heavy limestone rock upon the remaining shale fill material. The weight of the added material will helpd the layers of new and old roadway settle together over time.

The department has place asphalt patching on two occasions since the August 12, 2012 reopening date. These patches were laid to fix the expected settlement. The first temporary patch was completed on September 20, which was five weeks after the roadway's initial opening. The second more permanent patch was laid on October 3, approximately seven weeks since the project was completed.

TDOT said it would likely perform another asphalt patch sometime in the spring, in order to maintain the proper road level for travelers.
