Looks like they just blew off the connector plates.  It is an arch.  Romans 
didn’t need no stinkin’ connector plates.
A few minutes with a cutting torch on the bottom middle ought to do the job

This was probably all shaped cutting charges...  The problem with that 
is the internals of the steel.  They usually pre-cut some of the members 
to determine the composition of the charges and if they cut the wrong 
member they get the wrong results...

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.

Re: [AFMUG] OT - bridge implosion

I'd hit the 4 connecting points of the lower section to the arch, then
charges all the way across the arch peak. Detcord around the top of each
cable.

Failing that, there's always thermite or thermate.

Re: [AFMUG] OT - bridge implosion

 I have just enough nautical knowledge to seem stupid on the Internet...
My theory is that they were planning to neatly cut it into medium sized
chunks that could be reasonably lifted out of the river with a medium sized
crane on a flat barge and carried away. Severing the whole thing and
dropping it into the river in one piece would require a significantly
larger/more expensive crane and corresponding barge.

Not enough explosives at the severing points, or an underestimate of the
strength/grade of the steel?
