ADBF - River Raisin Approach Bridge (Blissfield)

Thanks! That explanation makes sense. To be honest, I was surprised to find that a small span like this had a builder plaque at all, let alone one from one of the major bridgebuilding companies.

Sometimes railroads had mass contracts for small girders or beams from a single company. Often these spans were used to replace wooden bridges. It’s likely the truss was a separate contract, instead of a single contract for several spans.

Nice find!

Interesting that this small bridge was built by the King Bridge Company, but that the main River Raisin truss only a few feet away was erected the same year on the same rail line by the American Bridge Company instead. You would think that the rail line would have used the same company for both spans.
