The spans of this bridge are different. The northern span seems to be pin connected while the southern span is riveted. The date on the southern abutment is 1928 but the builder's plaque on the southern span, the riveted one, is 1899. Was the southern span moved to this location? NBI says the bridge was built in 1928.
It looks like at least one of these truss spans was moved to this location, and quite possibly both. There’s an identical span to the pin connected span crossing the Dearborn River in Lewis and Clark county.
