Have You Ever Seen a Table Bridge?

About halfway through my looooooong client engagement up in Wisconsin I finally got the top corner room of the Downtown Residence Inn (top right corner in picture below).

What's so cool about that?  Well it sure beats being on the other side of the building looking at the TJ Max in the mall across the street.  This side of the hotel you gets a view of the Milwaukee River this hotel (that once was the Gimbell's department store) sits on.

They've got a nice walkway on both sides of the river called the River Walk that is worth seeing if you make it to Milwaukee.  Actually, I've been wanting to do a Happy Days / Laverne & Shirley tour, but I don't see much.  Here's one blog about it; http://postcardsandcoasters.blogspot.com/2011/05/milwaukee-sites-from-laverne-and.html.  

So... back to THIS blog posting's topic...

I've been thinking those bridges in the picture above were 1) drawbridges and 2) never going to open up on my stay.  I was pleasantly surprised when I was getting ready for work and started hearing bells clanging below.  When I looked out to catch them raising up for a boat to pass underneath.  To my surprise, they weren't "drawbridges" after all.  In fact, I didn't know what they heck they were.  Here's some photos of what I saw – pardon the quality; the Residence Inn sure needs to get a window washer up here on the 8th floor!!

I found the very informative Moveable Bridge wikipedia page which let me know these are Table Bridges.  I've never seen such a thing and just wanted to share them.  How you seen one of these before?  How about some of the more "exotic" movable bridges on that wikipedia page?
