The good work and some luck gave this drive a second chance on life today-
I have run wreckers in the past and have done a lot of technical rigging. This is a nice job, complicated by the obvious. It seems fortunate that this occurred over a main, concrete span support which I would guess allowed the bridge to "take" a load moment in a direction that it wasn't designed to absorb.
If I was anywhere close, I would take a look and see what they come up with for a removal.
I'm guessing that this "older" bridge was designed in the "slide-rule" era when the calculations were made and were "rounded" up to achieve the final specifications.
