The 1920 date the NBI gives for this bridge only applies to the concrete abutments, as the bridge superstructure is really just a typical timber slab identical to dozens of others built in Michigan in the late 1900's. The 1920 date itself is suspect, as that year has been used as a generic guess date when nobody knows just when a bridge was built. However, given this bridge's narrow width, it is probably a decent enough ballpark estimate for the age of the abutments.
