Not GMC but pretty dang interesting. This bridge in Durham NC, has a couple traffic cameras that capture the action. Also apparently has a warning system that flashes caution lights at too tall loads.
Watch what happens to the RVs who go through it.

I was once in a car heading opposite direction while 2 dudes in a 24' bobtail did the front wheels of the ground trick. I had a birds eye view of their faces as it unfolded. Priceless

I like the 5er that cleaned off his roof top unit and just kept on going. I don't recall what year that is in.

I can hear the conversation at the campground that night...
"Daddy, the TV isn't working"
"Honey, the AC isn't working either"
"Let me check the breakers...humm, they look OK. I'll go check and make sure we're plugged in.....OH CRAP Someone stole our AC unit!"

There's a website, 11foot8.com or some such. Guy has an office that
overlooks it, and he runs a camera. His website says he gets about one a
month, but every day trucks see the warning lights and turn away down the
side street.

Good find, Kerry. There were some doozies in there. I particularly liked the 5th wheel that slowed down and slowly scraped everything off of the roof.
In my home town there's a similar but smaller train overpass. I had picked up a step van and drove it home on my usual route without thinking about it. It dawned on me just as I was passing under the overpass that I had a roof vent that was taller than the 9' step van and the sign said the overpass had 9' clearance. I was waiting to hear the crunch and rending of metal, but nothing happened. The next day I went back to measure and the there was 10' of clearance. I was always thankful that they lied to me!
Another guy wasn't so lucky. He was driving a dump truck with the bed partially elevated. When the front of the bed hit the overpass it pivoted the cab up off the ground and squashed him against the underside of the bridge. That's probably when they started lying about the clearance.

Some years back they had just opened the I565 interstate spur into Huntsville. A wheeled crane, probably 40 tons, had the crane front end come off it's cradle and lock. The crane boom hit the brand new 4 lane overpass doing about 60mph. The crane stopped in 8.5 feed from 60mph, a considerable G force. Driver was unhurt but it moved the entire interstate bridge...all 4 lanes of it...4 feet and shut down the new interstate for several months while they repaired the bridge.
This was the overpass leading into the main gate at Redstone Arsenal and 10+ cars were on the bridge when it happened. Exciting times in the Old South for them.

Google "backhoe hits overpass" and check out the carnage that can be done by large items trying to squeeze under a low structure. The first two results are amazing. One overpass almost sliced in two, and another knocked completely off its supports.
