Description 

This Warren truss had a lot of V-lacing, mostly on the majority of its diagonal truss members; most of the Warren trusses from the '30's had built-up members consisting of angle iron and connected with batten plates. The bridge was also three spans long, which was more common with through-trusses, but not very common at all with ponies like this one.
