This bridge is noteworthy for being located in a county and region that has an extremely small number of historic bridges of any kind. This bridge, being an impressive pin-connected through truss, has an extremely high level of local significance. This bridge is also very noteworthy bridge on a statewide basis because its design is highly unusual. The most striking feature of the bridge is the vertical members, which use a built-up design that is common on pony truss bridges, but are extremely lightweight and unusual for a through truss. The design of the struts as well as the shallow a-frame portal bracing is also unusual. Despite these unusual designs, it is not known who the builder of the bridge is, even if these unusual designs might embody the distinctive details of a particular builder.
The National Bridge Inventory gave a 1929 construction date for the bridge which is clearly incorrect. The bridge may have been rehabilitated at that time or even relocated from a different crossing. However the bridge most likely dates to before 1910.
The six panel truss is configured as follows: Top chord and end post: back-to-back channels with v-lacing and cover plate; bottom chord and diagonal members: loop-forged eyebars; hip vertical members: loop-forged eyebars; other vertical members: paired angles with v-lacing; portal bracing: a-frame design composed of riveted angles; struts: paired angles with plate; floorbeams: rolled American Standard Beams (i-beams) hung from pins by u-bolt hangers.
This bridge is located on a section of road that was abandoned for vehicular use but was converted for non-motorized and off-road vehicles such as snowmobiles. Aside from the reconfiguration of the deck and addition of railings, the bridge has not been rehabilitated or altered since its time as a motor vehicle bridge. Jonesville Road goes north about a mile from Muskegon Road. It ends at a large parking area for an ORV trailhead. The bridge is down the hill behind the outhouse.
