A large concrete slab fell from Wheeling Island Stadium on Monday afternoon. No one was injured, and fortunately it damaged only a part of a fence below. It happened as work was being done following the discovery last week, that a large concrete panel had moved and become unsafe. Officials aren’t sure what caused that. Because officials still are not sure just what the issue is, roadways surrounding the stadium were closed to make sure no one got close enough to be hurt in the event another piece of concrete falls.
