Anyone else think there's a link between this design and Pan American of Moberly?

According to Tony, the PanAm of Newcastle never built these, and the only other listed builder of one of these bridges I can find is 5 examples allegedly built by Stupp Bros.

Another bit of evidence supporting this link in an excerpt from the MO HB Inventory from FraserDesign

In addition to the Shelby County Oak Dale spans, Putnam county seems to have a handful of these spans that match ones built by Pan American.

However, unlike the Shelby County spans, I can't seem to find proof of it in Putnam County.

Nearly all of the Bedsteads I have seen that are still in use have had their legs encased in concrete. I'm sure the county officials found this as a cheap and easy way to deal with deficiencies that often occurred with them.

As Luke said, it is a double intersecting warren. "Double intersecting" means there are two warren patterns with overlayed with the second offset one-half the distance of the of the pattern repeat of the first.

But are you sure it's a bedstead? Clearly it has vertical end posts, but to be called a beadstead the endposts have to extend below the lower chord and function as substructure. I can't tell from the photos where the lower end of the endpost is...

This would be a double-intersection Warren.

Can anyone tell me what type of bridge this is? Putnam County, Missouri has several of this type. I can see that it is a bedstead truss; however, the descriptive text for these bridges (which are obviously all related) varies between "Bedstead double-intersection Warren" and "Lattice bedstead" types. It looks like a lattice to me, but I'd like confirmation before I go around changing them.
