Notes
Survey number HAER MI-106
Significance: The 20 Mile Road Bridge is a large and early example of a riveted pony truss structure with no pinned connections. It is all the more unusual for its Pratt rather than Warren truss design because Pratt truss designs are typically pin-connected. It has been considered eligible for the National Register of Historic Places since 1992.
