I put National Bridge and Iron Works as the builder of bridge.
Wow, that definitely is a Parker Patent bowstring truss. Quite a find! Yes, Parker was directly involved with National Bridge. Here is the only other one I know about (and the only one I visited in person), bringing my known total to three in the whole country. http://www.historicbridges.org/massachusetts/lowerrollstone/...
Check this one out James:

I think you may just have found another example of a National Bridge & Iron Works product. The top chord does look very similar. The Elm Street Bridge had a deck truss added to it for extra strength many years back.
I do believe that Mr. Parker may have been directly involved with NB&I as well.
any info on this bridge would be helpful. i posted it as a parker pony truss, but in reality I have never seen a bridge like this. what kind is it? who made it?
I like the name of the lake!
