I guess that is the end of the Pratt Truss Era. If it is possible to consider some other bridges built of that tech. I know of one near Beaver Dam that got bypassed after it was too fragile to take our Datsun 1200 back in the 70's It's probably still there, but not possible to get anything on to that one.
There is another over Loch Raven near Baltimore, but it's closed to vehicle traffic now.
As far as the trucker being willfully stupid charge him. You cannot replace that kind of history.
