The HAER documenation for the Wagon Wheel Bridge seems to support Robert's comments:

Can you provide an article or something so we can properly split the categories?

Was it a different company or a reformation of the earlier company under new management?

Two separate and unrelated bridge companies based in Des Moines, Iowa, were both called the Iowa Bridge Company. Bridges built by the Iowa Bridge Company between about 1900 and the 1930s were built by a different company than the one that constructed this bridge. Any bridge attributed to the Iowa Bridge Company that was built between 1947, when the second company was formed, and about 1967, when it appears to have ceased operating, was built by the second company, not the first.
