I sat one night laughing my ... off at all the videos. Something that isn't readily apparent from the farther videos, but is a good thing is that the vehicles are primarily slamming into an I-Beam that has mounted a few feet from the bridge, so that is taking the brunt of the force (there's one exceptionally hard hit where the guy even shows how much the beam was bent) even though you can also occasionally see the bridge bounce a bit after some of the accidents.
Another one I found interesting was that so many people were claiming that the bridge had to be lower than 11' 8" and that's why they were hitting it that the DOT measured the bridge... According to the video
the lowest point is actually 11' 10.8" or so, which just makes it even worse when people are hitting it because they are then clearly over the 11' 8" posting, not just "scraping by".
I agree the railroad should not have to do anything about this, it is entirely on the stupidity of the drivers ignoring at least three signs and an automatic trip light that flashes when it senses an overheight vehicle approaching from a block or two back...
Sign 1: http://goo.gl/maps/D6IvH
Signs 2: http://goo.gl/maps/5RXZT
And of course the final reminder: http://goo.gl/maps/wB2nG
Ignoring the signs is one thing, or it could be ignorance of the height of your vehicle, which I could certainly understand for some of the campers that lose their air conditioners... But a lot of these are company trucks and things... I really want to know how you explain that one to your boss or contractor... "Uh, I've been driving truck for x years, but, uh, I don't pay attention to clearance signs or big flashing yellow lights..." I wonder how many of the bosses include the words "you" and "fired" in their next sentence.
