Located between Ardoch and Oslo along North Dakota Highway 54, this bridge crosses the North Marais River just east of Interstate 29.
Built in approximately 1905, the bridge features an attractive deck plate girder span, set onto timber substructures. The bridge utilizes a very common design seen throughout the Soo Line system, including a long trestle approach.
This style bridge was commonly used on branch lines, where a larger span was required, but a permanent substructure was not. Oftentimes, these girder spans would be moved from a mainline to replace several trestle spans. It is unknown if that is the case here.
Overall, the bridge appears to be in fair condition, with no major deterioration noted. Unfortunately, no plaques could be found on the bridge. The author will attempt to find more information on this structure.
The author has ranked this bridge as being locally significant, due to the common design.
