Underwater bridge
 

Check this bridge out.
This bridge is half under the water, for ships to pass and then again, it comes out on the other side. Truly a marvelous piece of engineering!
This bridge is between Sweden and Denmark ... Picture taken from the side of Sweden.

Ah, we got a few of them right here in the good ole US of A......

The Cheasapeake Bay Bridge Tunnel comes to mind.....in fact, I will be driving over it two weeks from tomorrow.....:)

That's right! An incredible engineering marvel.

Speaking about marvels, the TV show Modern Marvels did a show on that bridge. Very interesting episode!!! ;)

Steve, don't you mean under it :D

very cool...

Looks like a great place to fish:D

Cal....well first over it, and then under it, then over it again, and then under it, and then over it......;)

Okay, so the CBBT has three sections of bridge/causeway, and two tunnels.

Mike.....on the CBBT, at the south end of the south tunnel, they have a parking lot, resturant and gift shop, and a fishing pier.

Underwater bridge??? What do you Rhode Island guys call an over-the-water tunnel ? :confused:

The one time I travelled across the chesapeake bay bridge/tunnel, a nuclear submarine was just going across the entrance to the tunnel as we went down the ramp. So I can honestly say I've driven under a nuclear sub:D

Eben, that's just awesome!!
