I decided to make my own hybrid to some extent in an attempt to meet my goals of making it 3D printable, as close as possible to the real thing, and easy (sort of) to assemble at 1:100 scale. Obviously there are a number of compromises in the design to make this possible!
This illustration shows the key elements of the bridge. There are a number of them that got lost on the way to 1:100 scale such as the End Post, Sway Brace, and the rest of the smaller parts. The Raker got translated into Braces that support the Panel and are large enough to print and handle. The Stringer left the building when I wisely decided to print a one piece road bed rather than one built from components (honest, I did think about it)!
Transition from the first build to the second looks pretty good. Am not sure what to do about the ramp to the walk way but that is the only issue remaining in terms of design change. A little construction boo-boo in that one corner is a little higher than the others!
...second build. In the image viewer you can go back and forth between them... :-o
