Transformation

On this design, I was going to used a pulling system. (3) wheels on each side of the bridge will pull  the opening road bed with a gear system installed on a steel frame tower. I decided not to used this design because there was not enough support for the opening road bed.

The design of this bridge was closed to what I want but it needed  more support.
