Located west of Marquette, this large girder is the 24th crossing of Bloody Run.
The previous bridge was a through truss bridge built in the 1890s, and was replaced as part of a mass upgrade of trusses in the 1980s.
Two replacement spans were brought in from unknown locations. The larger span appears to date to approximately 1920, and may have originated from a bridge nearby. The smaller span was built in 1945 at an unknown location.
These two spans rest on concrete, stone and steel pile substructures. Unfortunately, information on these spans will be hard to come by.
Overall, the bridge appears to be in good to fair condition, with minor deterioration.

The author has ranked the bridge as being locally significant, due to the common design.
