Never too old to have a happy childhood!
Interesting video on that "11foot8.com." I'll tell you, I held my breath when that bus went under the bridge, I'll bet the dust got brushed off the bus' roof!
So the driver went AWOL? Two things, either he went looking for a pay phone ( Good luck on that in this day and age!) or he panicked and ran. More than likely the second option.
Amazing what I see on the roads in my daily travels. I remember back in the 60's there were some road safety commercials on TV that ended with "Watch out for the other guy!"
Just as true now as then. Maybe more so.
On King Street in Toronto between Dufferin street and Shaw street is a railroad overpass. There are electric eye warning lights for trucks on either side. On the west side between the sensor and the bridge is a side street called Atlantic Avenue. There are no sensors on Atlantic. A brewery was being dismantled at the foot of Atlantic. A truck hauling brewing kettles turned to go under the bridge. You can figure out the rest.

Dang, beat me to it.

I was a mine construction manager in Western New York a number of years ago. We contractedwith a specialty heavy haul trucking company to deliver an over sized mine hoist drum through Hornell. The trucking company hired a pole car to ensure there was clearance for the many underpasses along the route. At the final underpass the pole driver alerted the truck driver there was insufficient clearance. What did the driver do? He put the pedal to the metal and the mine hoist hit the bridge damaging teo girders plus dropping about 50 tons of mine hoist onto New York route 36 causing traffic delays, damage to the mine hoist, bridge and roadway surface. And we got our names in the news paper.
There isa no cure for stupid.
We engineers put in a design safety factor to account for things we can't directly identify as loads. Of course there is no way to economically design for stupid. A dump truck driving down the roadway with the bed raised is a good example.
Remove the old paint, rust etc down to "bright metal." Get your grabs on a product called Chlor Rid (might be clor rid) and apply that prior to priming. It is supposed to remove the chlorene iont that makes the rust.
Every time we make something fool proof, they come up with a better class of fools.
I agree that railway rust is mostly a purely cosmetic issue, but sometimes it grows into a bigger issue. The city of Edmonton is finding that out now, which is throwing a monkeywrench into some future light rail expansion plans:

Makes one wonder about all the other large steel bridges of the same age that are still handling mainline tonnage, nothing lasts forever...

Since the High Level bridge also carried road traffic, there may also be winter salt accelerating the rusting. Nothing lasts forever, which is why some of the large railway truss bridges have had quite a few components replaced over the years, especially the floor system. We are not told which specific members were of particular concern in the Edmonton article.
In structural design it common practice to design for 125-150% of the anticipated load. I guess in Edmonton the cat used up its nine lives after 100+ years.
When it was originally built, they didn't expect it to last that long. Think they got a good return on their investment?
Always is amusing how the dime store lawyers can pass judgement on what engineers and surveyors do. The current generation of coddled buttonpushers (many are i-Zombies) is dumber than the previous group. (and a lot less reserved or understanding)
