Wow, thanks for pointing out this rare bridge! I have a brief discussion on the type here: http://www.historicbridges.org/truss/millcr/. Only a handful of these bridges have been found so far. Hopefully the historic bridge community will find more as time goes by.

I added this bridge to the category.

This Pratt Deck truss railroad bridge has a curved bottom chord and I am interested in learning more about this feature from our resident historical engineers.
