Supposedly the reason for taking it down was due to being old and

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.

My theory is that they were planning to neatly cut it into 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
