Holy crap that's so freaking weird..........

It would be like losing your tires, going off the edge, bike and all upside down and then landing safe and sound, rubber side down on a road below..... WTF.

That is awesome!

So what I want to know is why that thinger on the top of the bridge switched from the right to the left. 

[weaselnoze]

perspective? maybe its really in the middle..

[ajgs500]

Structurally I dont think it could be.... it really doesnt look like it could be in the middle.

I bet the guys below had one hell of a ride!

Meh.  Happens all the time!   

Do not attempt it on a GS.

  Wow, just when you think you've seen it all !!

So what I want to know is why that thinger on the top of the bridge switched from the right to the left. 

if you're skeptical, notice that in the 3rd picture the sign above the roadway says 'vertical' ... in the 10th picture you can see it still says 'vertical' even with the boat on the opposite side.

plus, in the 9th picture, the boat is surfacing on the other side while listing towards the bridge; how would it do that on the upstream side?

tugs are bottom heavy for a reason, still cool it didn't f%$k up the deck more than it did.

These are just to illustrate my question.

Yeah i concur with Egaeus.

That thing is really just as wide as the bridge but is towards the middle of the bridge. Hence the distance and change in perspective cause it to "move"

I've always wanted to do something like that on a bike. Like do a 360 sideways while moving 80 mph and then land safe side up

Clues from the background:

In the first pic, notice the pattern of light coming through the trees, and the small cloud just above it.

The same light pattern (and cloud) show up in the middle of the second pic.
