Barber Creek Bridge

Looks to me like it's a bowstring pony truss. It's the diagonals members that make it a truss, and I see those.

The details are hard to see, but it sure looks like it could be one built by King Iron Bridge & Mfg Co. From http://kingbridgeco.com/siapaper.html it seems he was pretty busy building bridges in the late 1800s. So if the photos were from 1916, the bowstring bridge could be 40 years old.

I do agree that it appears they are removing the bowstring after installing the concrete bridge. Notice the coursed stonework abutment. It sure looks older than the concrete.

Exact location unknow, the description of the images linked in the sources section mentions the building of a bridge, but I'd assume the they are removing the metal truss (or arch, correct me if I'm wrong it being a truss)after the adjacent concrete bridge was built.
