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 on the southeast side of Frazee, this deck plate girder viaduct carries the former Northern Pacific Railway over the Otter Tail River and River Drive. The first bridge at this location was likely a timber pile trestle. In 1896, the bridge would be reconstructed with a deck plate girder span, set onto concrete abutments and steel bents. During a double tracking project in 1906, the bridge would be widened by adding an identical structure to the south side of the bridge. Due to the increasing weight of locomotives, the original 1896 structure would be strengthened in 1911, giving the bridge its current configuration. The bridge consists of a 56-foot and two 36-foot deck pplate girder spans, set onto steel bents, concrete pedestals and concrete abutments. The girders use a standard design for the era, and steel towers were likely used to minimize the amount of masonry required for the bridge. Two unknown contractors fabricated the superstructure, while unknown contractors constructed the concrete substructures. While uncommon in this area of Minnesota, these small deck girder viaducts were commonly built across the United States, due to the ease of construction, economy and durability. Overall, this bridge appears to be in fair to good condition, with minor deterioration noted. The author has ranked this bridge as being locally significant, due to the common design.
