Same truss design as UP ex RI bridge over Des Moines River in Des Moines. That one was built 1920 by American Bridge Company, and contains almost an identical design to this one (based off the limited truss views)

I fully agree with Tony here; subdivided Warren for sure.

At first glance it is easy to categorize it as a Baltimore truss, but the alternating diagonals help to classify it as a Warren. The panels have then been sub-divided similar to how they would be in a Baltimore.

This is a really neat bridge!

I don't think this is a warren truss, at least not a basic one.
