OK, mechanical stuff is not my strong point. But for anyone who watched
the video of the failed bridge implosion in Little Rock, Arkansas, what

bridge deck, both of which are in compression. It seems to me they
needed to sever the cables, which are in tension. That at least would
have caused the deck to collapse.

Supposedly the reason for taking it down was due to being old and
"structurally deficient", but it seems it wasn't. Or it was declared
deficient to hand someone a contract for its replacement.
