It's a railroad lift bridge:
Nothing particularly "historic" about them. I used to run freight trains over the one named "Upper Bay" in New Jersey, in and out of Oak Island freight yard. Looked almost exactly like that.
Hmmm....This bridge looks to be large enough for ocean-going SHIPS to pass under without trouble. Is Bezos' yacht too high, or too wide?
I can't imagine a "yacht" too high to fit under that. Perhaps Mr. Bezos ought to have the upper decks removed to get it out of there.
Or... he could do this:
- Lower the lift span down to track level
- Float a barge under it
- Disconnect the suspension cables and move it out of the way until the yacht is clear, then put the lift span back.
If the yacht is too wide... well, next time consider how you're gonna get it OUT OF there before you build it...
