Long time lurker first time poster...
Years ago (maybe 10?) when I worked in news I got to cover a story where a Caterpillar D10 dozer met a bridge the driver thought was higher then it really was. The people in cars behind the tractor trailer carrying the dozer said the D-10 bounced. Bear in mind that a D-10 weighs over 146 thousand pounds (73 tons). The bridge obviously suffered damage and was closed for a short period of time.
The dozer on the other hand, actually faired pretty well. It was on it's side after being ripped from the trailer but looked pretty much like a D10 on its side. They took it back to the Cat manufacturing plant to be checked out. I'm told that with some very minor repair to the engine and a little paint it was apparently put back out for sale. I never heard if they told the dealership it was shipped to and the customer who bought it that it had duked it out with a bridge.
