Virginia Sinkhole

I-81 Sinkhole Forms in Collector Lanes
A collector lane of Interstate 81 in Montgomery County was closed Monday because of a sinkhole. A sinkhole formed beneath the right southbound lane just north of the Exit 118C ramp, the Virginia Department of Transportation said. Crews will repair the sinkhole by excavating it, filling it with rock, capping it with concrete and paving over it.

I wonder how many sinkholes there are out there in the boonies for every one that affects the community, such as this one underneath an Interstate. There must be a lot!
