The sudden opening of an enormous sinkhole caused a section of Highway 516 to collapse last night near Dover, Ohio.

About the size of four football fields, the sinkhole may have been created by dredging for sand 50 feet below ground, WKYC reported.

According to WKYC, Ohio Department of Transportation engineers are inspecting the sinkhole, and are likely to begin permanent repairs sometime in 2013. No injuries were reported.

Here's footage of the damage:
