40 Foot Sinkhole in Tenn. Stadium Endzone

A 40 foot by 40 foot sinkhole at Austin Peay State University Governor's Stadium in Tennessee

A large 40 foot wide by 40 foot deep sinkhole opened up just outside the endzone of Austin Peay State University’s Governors Stadium in Tennessee. The stadium is currently undergoing upgrades for next year’s football season. Sinkholes are not unexpected on Austin Peay campus, and the video below shows one example of how the University has actually incorporated the remediated sinkholes into the landscaping. Representatives from the University and the contractor expect the sinkhole will be filled without any problems.

That looks like a pretty planar joint set dipping right into the roadway and everything was wet from the recent rains. Click through for the video.
