When I first saw the picture I wasn't sure what I was looking at. Then I thought it might be faked also but there are multiple views from several sources and eye witness testimony.

A pothole, well - technically a sinkhole, just about big enough to pull a Thelma & Louise into. Estimates are, variously, 70' to over 100' wide and 100' to 300' deep. And if only one or two guys work the shovel while the other three stand up supervising it's going to take a while to fill in. That's what they call job security.
