Hello, I am constructing a trestle bridge circa 1920-1930.
Can someone please tell me if a wooden trestle with a steel plate girder central section would be feasible for 1920-30 USA ?
Does anyone have any photos of this type of combination steel girder / wooden trestle bridge ?
I found one picture of what I want. See attached. Anyone know of other similar pics ?
Thanks very much for any help.
