Listed Clarke, Reeves, and Co and Phoenix Bridge Co are the same company. The Clarke Reeves Co turned into the Phoenix Bridge Co in 1884. This bridge was built during the Clarke, Reeves Co era.
Actually, when you think about it, rivets are almost ALWAYS loaded in shear. And I assume the Phoenix Columns are used in compression versus in tension, so there should not be much stress on them.
Totally fascinating. They created tubular supports by riveting together semi-circular material. That's pretty unique. It's also asking a lot from the shear-strength of the rivets.
Neat Whipple Truss whether built for road traffic or railroad!
Wow, it looks a little spindly for a railroad bridge. But here it stands all these years later.
