Tony, what are your feeling on Luke's suggestion that all examples of this truss style were products of one of the two Pan American Bridge Companies? I've never associated a builder with the Powers Highway Bridge in Michigan. Exact details vary, specifically, some bridges of this style include built-up lifting holes for installation equipment/cranes.

Likely from the lesser known Pan American Bridge Company of Moberly, Missouri and not my hometown Pan American Bridge Company of New Castle, Indiana. The Missouri firm actually took it's name from the older Indiana firm, who also supplied some of the trusses for the fledgling company.

I'm glad I found a rarity, and I can only hope the towing/wrecking company that seems to own it now leaves it be.

Simple Lattice pony I would say. I have heard the more unique Canton ones referred to as a "Lattice Girder".

These were very common in Missouri. There were 33 of them at the time of Fraser's historic bridge inventory in the early 1990s (see attached).

The inventory called them "lattice bedsteads", which as Nathan points out on his website, is not really accurate. They were lumped together with other true bedstead truss types, which were so common at the time in Missouri that very few were considered National Register eligible.

I don't know offhand how many of these "lattice" bridges are left, but it can't be very many. True bedsteads have also dwindled: what was once the most common truss type in Missouri is now one of the rarest.

This bridge bears an eerie resemblance to a relocated one I discovered in Iowa: https://bridgehunter.com/ia/muscatine/bh79331/

And while seeing if other examples existed in Missouri, I came across an entry that led me to this page on Nathan's site: https://historicbridges.org/bridges/browser/?bridgebrowser=m...

I have a feeling that spans of this specific style were primarily a Pan American Bridge Co. product.

I've emailed Nathan about it and hope he reaffirms my suspicions.
