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. James to Le Mars segment as the Worthington Subdivision. The line continues to carry steady traffic.

Located west of Butterfield, this deck plate girder bridge crosses an unnamed creek. Built in 1913 to replace a trestle, the bridge consists of a single 30-foot deck plate girder span, set onto concrete abutments. This style of bridge was commonly used for small structures along this route, as it was durable and easy to construct. The 30-foot size was used at numerous locations along this route, as it was a standard design. Overall, the bridge appears to be in fair condition, with some deterioration noted throughout the concrete. The author has ranked this bridge as being locally significant, due to the common design and newer age.
