Welcome, dear residents of the forum! I can not believe that finally completed the picture ... It took just tell you a lot of time and effort and did not fit well, not in what is presented before the time =) one word "unfinished" =) Let me explain the principle of the bridge: The point is about the same as in the famous Ferris wheel attraction << >>. Only in this case the cabin sealed and attached to the tape, which puts them under the water at one end of the bridge and picks up at the other end of the bridge. The special design allows you to always be in the booth upright position during movement. From this angle is only visible surface part. Fixing the axis of wheels two sides to the bottom of the bridge is below the waterline. Enjoy!
