In 1871, the Northern Pacific Railroad (NP) continued building west from Staples, Minnesota; reaching Moorhead by the end of the year. The line extended to Duluth on the east. The line would be extended west to Bismarck, North Dakota by 1882. In 1877, the St. Paul & Northern Pacific Railway (StP&NP) would purchase and complete the partially built Saint Paul and Pacific Railroad line between Sauk Rapids and Brainerd, a distance of 61 miles. At Brainerd, the line connected to the NP line. Between 1883 and 1884, the StP&NP would complete an additional 66 miles from Northtown Junction in Minneapolis to Sauk Rapids. A 33 mile connection between Little Falls and Staples would be completed by the StP&NP in 1889. In 1896, the NP and StP&NP were sold and reorganized as the Northern Pacific Railway (NP).
NP operated the Minneapolis to Moorhead segment of this line as their mainline between the Twin Cities and the Pacific Coast. As a result, significant reconstruction was done to the original route. The route was double tracked between 1902 and 1910, including a large reconstruction of the route between Hawley and Dilworth. In 1970, NP would merge with rival Great Northern Railway and the Chicago, Burlington & Quincy to form Burlington Northern Railroad (BN). In 1996, BN merged with the Atchison, Topeka & Santa Fe Railway to form BNSF Railway. BNSF currently operates the Northtown to Moorhead portion of this line as the Staples Subdivision, and it is one of the busiest railroad lines in Minnesota.
Located between Perham and New York Mills, this small deck plate girder bridge crosses Wavy Drive (Old US highway 10). Built in 1928 as part of a grade separation project, the bridge consists of a single 36-foot deck plate girder span, set onto concrete abutments. The bridge runs at a 30-degree skew, necessary for the wide curves of the surrounding highway. This style of bridge was commonly used for grade separations, as it was durable and easy to construct. Overall, the bridge appears to be in fair to good condition, with no significant defects noted. The author has ranked the bridge as being locally significant, due to the common design.
