Pat -
You wouldn't have been the first to come in contact with that RR overpass, and I'm sure won't be the last either.
I was a marina attendant at Shilshole while in college. We leased a rotating garbage truck -- the vendor would drop a new one off each week, and leave us with an empty. We would collect the dumpsters off each dock, and then leave the full truck for exchange.
High on the front end of the rear container was a large, very solid gear; part of the loading, or compressing, or dumping mechanisms on the truck. We didn't pay too much attention to it, but from direct experience, we now know that the cab of the truck fits under the bridge, but the gear mechanism does not!
That must have been one quick stop; the RR bridge escaped virtually unscathed. I wondered how many -G's the driver might have experienced?
The approved route was south and east through Ballard -- the drive thought he'd take a 'short cut', north under the RR, and then up the hill. A supervisor was called, and the driver was fired on the spot.
UW MED SCHOOL PARKING GARAGE:
As a grad student I often parked adjacent to the med school. The lower levels had very limited clearance -- even in a car I felt like ducking my head every time.
My advisor drove a pickup, which felt even tighter, but still had adequate clearance. But he told me of another faculty member that installed his camper in anticipation of a holiday weekend. It took a few milliseconds for him to recognize the strange sound as he drove into the garage. By the time he hit the breaks his truck was inside the garage. The camper, however, was now sitting on the ground just outside the garage.
Oopsie!
