Hey, I found a couple bridges after being inspired by a night of racing around in Ubisoft's The Crew. Weirder things have happened.

Thanks for finishing the categories. I was pretty sure it was a Pratt, but I'm still learning. I don't know what caused my seemingly random curiosity about this bridge, other than maybe a new interest in Idaho, with the recent addition of Idaho to American Truck Simulator, but I'm glad I researched it.

I do question if this is a railroad span or not. The width and portals scream railroad, the rest of the bridge makes me have some doubts. This could either be a former narrow gauge logging railroad span or a frankenbridge if it is indeed a railroad span.

I agree with Luke on this one... A relocated span.

It also looks to be a relocated truss...

This is actually a through truss bridge, rather than a pony truss, as originally listed. I've added a link with pictures and adjusted the listings. Cool looking bridge, but it appears to be closed.
