Though armor going through bridges brings up some great dioramas. More than one book has some photos of German armor going over the side of a bridge or collapsing a bridge due to weight. Best I saw was a Tiger that was vertical against the bank with another tank thinking of trying to pull it out. Good luck on that since there was a war on.
If you look up the super tanks that existed only in the minds of the engineers at the end of the war, some pretty much were way over weight limits of all the bridges in the Reich. Not to mention being able to ford streams. Pretty much a pillbox, great model but a pillbox in place. A few were scratchbuilt and on the web. Now I've got something to kitbash big time...though where I'll get a 16 inch naval gun in
1/35......
Going on to a V-2 site,

in some of the other pages Germans would whack bridges trying to get equipment through to a location. Lots of opportunities for scrapes, tight fits and turns.
I seem to recall in one of the History channel videos, one of the tanks that was recovered for a museum was the one unlucky enough to break through the ice fording a stream that others in the column made it across. With all the water colors and gels, good ideas there too.
