Located west of Appleton, this through and deck plate girder bridge crosses the Minnesota River. The previous bridge at this location was a wooden structure. In 1916, the bridge would be rebuilt with steel spans. As a result, a 70-foot through plate girder and two 32-foot deck plate girder spans were added to the structure. The bridge is approached by nine trestle spans on the east end, and eight spans on the west end. The entire bridge is set onto timber pile substructures. This style of bridge was commonly used by railroads throughout the United States, as it was durable and easy to construct. It is unusual that concrete substructures were not constructed for the bridge, as GN operated this route as a mainline. It is unknown if the bridge was built using secondhand spans. Overall, the bridge appears to be in fair to good condition, with no significant deterioration noted. The author has ranked this bridge as being locally significant, due to the common design.
