Apparently the Charlotte Motor Speedway was built in part on top of a landfill! A LANDFILL!! Now, I’m no civil engineer but it seems to me that fill would not make for a suitable base for a permanent structure, and even less suitable for a roadbed that will have a varied and intensive dynamic load placed upon it. …well, it isn’t suitable. You can see more pictures from WSOC TV’s article, Sinkhole Forms at Charlotte Motor Speedway. Wow. How does this happen?
Now, even if the speedway does fix this problem, one has to wonder just when the next sinkhole will develop, and where. Can you imagine the chaos this would have created during a race weekend? Now imagine if it happened on race weekend underneath the track! File this under FAIL.
