Lots of old bridges in rural PA that are scheduled for replacement and posted for 10 tons or less, but now and then someone will run a triaxle across one and wind up in the crick.
Coupla years ago there was a pic in the news of one such collapse. Front wheels of the dumptruck were on the roadway at the far end, rest of the truck and bridge were in the drink.
Rode along once with a cousin that delivered bulk Agway feed to dairy farms. Three compartment aluminum feed box on a triaxle, probably 18-20 tons of feed, fully loaded?
One of the gravel roads going back to a farm had a little bridge signed for 10 tons, maybe 30' long, at the bottom of the hill. We zoomed across that thing 'bout as fast as the truck would go and still stay on the road.
Asked him WTH that was all about, thought we were gonna wind up in the ditch. Cousin said he didn't wanta spend any more time on that bridge than he had to, so it wouldn't fall in.
I asked him WTH he'd do if it collapsed behind him and he was on the far side. No other way outta there.
