The first movement I used was the lift. This picture is a good example because the
car lift is the way I wanted to make my lift. The only thing different about it is to
add pulleys into my system. The pulleys pull and retract the cables which
move the moveable section.

The Slide
movement is another way I thought it would be good to move the bridge
section. One end of the slide is
connected to the moveable section of the bridge and the other is connected
to the stationary section of the bridge.
Which retracts the bridge section back and forth?
