One of the most unique bridges in the Upper Peninsula of Michigan is located across 1st Avenue in Bessemer.
Built in 1896, the abandoned pony truss utilizes an extremely uncommon design.
While most pony trusses are extremely distinct as such, this one is not. It follows the shape of a traditional curved chord through girder span.
However, closer inspection finds that it is indeed a pony truss span. Specifically, it is a 7-panel riveted Double Intersection Warren Pony Truss.
This unique main span is also known to railroads as "lattice girders", due to the resemblance of a hybrid. Many similar bridges were built, however most feature vertical endposts.
In addition to this main span, the bridge is approached by several trestle spans on either side. The entire bridge rests on wooden substructures.
Overall, this unique bridge remains in good condition. After being abandoned since 1999, the bridge was given a rehabilitation and a ATV path installed over the structure.
The author has ranked this bridge as being highly significant, due to the uncommon design and old age.
