In 1865, the Minnesota Valley Railway Company began construction on a new railroad line between Mendota, Minnesota and St. James, Minnesota. The first 22 miles would be completed between Mendota and Merriam Junction in 1865, followed by 17 more miles to Belle Plaine in 1866, 16 additional miles to Le Sueur in 1867, 12 additional miles to Kasota in 1868, and 22 additional miles to Lake Crystal, Minnesota in 1869. Also in 1869, the Minnesota Valley would complete 5 additional miles from Mendota to St. Paul. In 1870, the Minnesota Valley would be purchased by the St. Paul and Sioux City Railroad (StP&SC). 22 additional miles to St. James would be completed in 1870. The StP&SC completed 58 more miles from St. James to Worthington, Minnesota in 1871; and 64 additional miles to Le Mars, Iowa were completed in 1872. At Le Mars, the route connected to an existing railroad, over which the StP&SC used trackage rights to reach Sioux City.
In 1881, the StP&SC would be sold to the Chicago, St. Paul, Minneapolis & Omaha Railway (CStPM&O), also known as the Omaha Road. The Omaha Road would come under control of the Chicago & North Western Railway (C&NW) the next year. This route became the main line of the Western District of the Omaha Road. The Omaha Road would formally be merged into the C&NW in 1959. The C&NW would be purchased by the Union Pacific in 1995, which still operates the St. Paul to St. James segment as the Mankato Subdivision. The line continues to carry steady traffic.

Located on the west side of Shakopee, this bridge carries the remaining spur of the original Hastings & Dakota line former Chicago & North Western Railway across County Road 69 (former US Highway 169). Located parallel to the former Milwaukee Road bridge, this bridge was constructed in 1957 to replace an older deck plate girder and trestle bridge. The bridge consists of a 100-foot, a 99-foot, an 80-foot and a 77-foot deck plate girder spans, set onto concrete substructures. The bridge is set at a 57-degree left skew, runs at a curve and uses a ballast deck. The east and west piers are each a triangular shape, which accommodates the heavy skew of this bridge. On the west pier, the north face uses an extra hinged span; identical to the south face of the east pier. An unknown contractor fabricated the steel for this bridge, while the Kraus-Anderson Construction Company constructed the substructure and erected the bridge. Typical of grade separations from this era, this bridge features a handful of decorative features, such as attractive railings. This type of bridge was commonly used by railroads for grade separations, as it was durable and easy to construct. A bypass of Shakopee opened in 1995, and the roadway underneath this bridge reverted to Scott County ownership. As part of a major construction project, the bridge was rehabilitated in 2012, which included repairing deteriorated concrete and repainting the entire bridge. Overall, the bridge appears to be in fair to good condition, and the bridge was rehabilitated in 2012. The author has ranked this bridge as being locally significant, due to the newer age.
