Note that the second picture seems to have added truss structure under the deck that is not in the first picture. I would guess that the first picture is an early, as built image and the second is truly a 1901 image, late in the bridge's life with reinforcement added to extend the bridge's life with extra capacity.

If anyone has the ability to do the research, it would be neat to find out more on this bridge's history (and maybe more and better pictures).

I'm guessing that the builder was Beckel, although the decoration reminds me of Corwin Iron Works of Lambertville, New Jersey (Lambertville Iron Works). Also, it looks like it was built to Lowthorp's design/patent. Can anyone confirm?
