Trestle advice please

[fran1942]

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.

the central span is definitely made of steel, and probably a replacement for an original wooden truss. Great looking bridge to model.

It's metal. Steel to be exact. It's called a "deck plate girder bridge"


I have some pics of through and deck girder bridges here, although, they are not as rustic as the one you show.

thanks guys. Please tell me would a bridge like this with a steel centre span be feasible for 1920-30 USA ?

Also, were centre spans of this design ever made of wood, or are they always metal ?

Thank you kindly.

From my research, most timber trestle weren't made to clear-span distances like bridges. I've seen lots of pics similar to that above, but don't know if the plate girders are original or replacements. I say go for it. Don't forget to post some pics when you're done.
