Nathan:

Thanks for the input. I have added WIBC as the likely fabricator. I also removed the Kansas Default Date of 1910.

Looks/sounds like it has all the hallmarks of an 1890s WIBC to me.

Thanks for getting out in the mud and finding this one. I was not aware of it when I lived in Kansas - somehow I missed it in the NBI.

I would not be too surprised if this is an 1890s Wrought Iron Bridge Company span. I have seen A-frame portal bracing and "sideways" verticals on some of their bridges. I am not quite ready to say WIBC definitively however.

Interestingly, the hip verticals on this bridge look like they might be four-prong eyebars. If so, this would be a somewhat uncommon feature.

Found the ol beauty today - down a VERY muddy (danger danger) still-open road (although it looks like private property) - talked to farm hand, said folks still, about twice a week haha, drive across it. Cool, solid Pratt.

This bridge still exists. Nemaha County once had a massive collection of truss bridges (mostly ponies), but nearly all have been demolished in the last few years.
