This bridge is an example of a state standard plan for a steel
stringer built in Michigan from about 1927 to 1932. The bridge design was only
built for a few years, but many examples were built. This bridge has had Armco
guardrails added, but the original railings remain behind them. The original
railings have one area of spalling, but overall the concrete railings, the
concrete encasement on the outermost stringers, and the abutments are all in
very good condition with little spalling.
