CLARKSVILLE, Tenn. - Construction crews in Tennessee are working to fill a sinkhole that opened at Austin Peay State University's Governors Stadium.

The Leaf-Chroniclereports the sinkhole started out small, about 3 feet by 5 feet, but workers have had to dig a much larger hole - about 40 feet deep and 40 feet wide - to find stable bedrock.

The hole was discovered about a month ago where the football field meets the track during a project to replace the main stadium building.

Mike Jenkins, superintendent for Nashville-based Bell & Associates Construction, told the newspaper sinkholes are common in the area and the budget included sinkhole remediation funding.

Jenkins said workers continued to excavate Monday while officials met with a geotechnical engineer. He said the hole will be filled with rock and concrete.
