I was directed to this bridge by the Washtenaw County Historic Society. Although the society did not mention anything about it, this bridge appears like it is on private property now, as there is a fence you have to walk around beside an old mill to get to the bridge.
This bridge is immediately unusual and significant for its unusual bottom chord design. From the hip vertical connection to the end post connection, the bottom chord runs at an angle. This is a very unusual detail, and the bridge stands out as significant on those grounds along. Otherwise, the structure is a good example of a full-slope pony truss with good historic integrity. The only thing missing is the deck. The abutments are an unusual combination of stone and concrete. There are the ruins of a dam under the bridge. Original lattice railings remain on the bridge, and there is lattice on the verticals, while v-lacing is present under the top chord and end posts.
