The construction style strongly suggests this bridge was built before 1954, but I failed to find any data about where it may have come from.

Grew up in this area and the story that I have heard was that the bridge at Cascade was moved from Lick or Sugar Creek when Lake Springfield was built in 1934, since it would have been underwater at full pool. When the bridge was put in, the creek was completely dry making the work much easier. There used to be a thriving town at Cascade, but nothing but the bridge left.

I would have to agree with you. Seems like way too much lacing here for a 1950's truss bridge. 1920's to 1930's seems more appropriate.

The lower chord with it's laced pairs of angles is very unique.

When I got to it, it struck me that this is a big bridge! The size of the members, the clearance height, etc. After visiting the Bolivia Road bridge this one is massive.

Regarding the build date, it would really surprise me if this were built so recent as 1954. It feels to me like a 1930's.

I included a photo of some of the concrete rubble near the north abutment. Is it just misc. rubble? Or is it broken pieces of an old bridge?
