Well the bridge seems to have generated some interest.
Here are a few details:

I scratch built it several years ago.
It is all wood except the steel wire tension rods, the brass tacks used as rivets, and the cardboard used for the “steel” gussets.
All the lumber is to scale in width and thickness.
I only used 8 pieces of wood that run the full length.
It is 4 feet long, a 64 foot span in 1/16 scale.
It is a Howe truss design, a pony truss without top bracing.
Only wood glue “Elmers”, was used to hold the bridge together, the 360 rivets are decorative.
I have load tested it to 70 lbs in the center with no measurable deflection.
It weighs less than a single 2x4 the same length.
The design is intended to look like a bridge from 1900 to now.
I built it as a prize to capture or hold in tank battles.
It was a very fun build.
