In 1873, the Burlington, Cedar Rapids & Minnesota Railway (BCR&M) constructed 24 miles of new railroad, extending from an existing line at Vinton, Iowa to Traer, Iowa. In 1877, the Burlington, Cedar Rapids & Northern Railway constructed an additional 24 miles of new railroad, extending from Traer to Holland. In 1878, the BCR&M was acquired by the BCR&N. In 1880, the Cedar Rapids, Iowa Falls & Northwestern Railway (CRIF&NW) constructed an additional 79 miles of new railroad, extending from Holland to Clarion, Iowa. The following year, an additional 59 miles of railroad were constructed, reaching Emmetsburg, Iowa. In 1882, an additional 70 miles of new railroad were constructed, extending from Emmetsburg, through Estherville and Lake Park, Iowa, to Worthington, Minnesota. In 1884, the line was completed from Lake Park, through Pipestone, Minnesota, to Watertown, South Dakota. The CRIF&NW was leased by the BCR&N in 1884. Throughout the 1880s, the BCR&N became a major railroad in Iowa, connecting towns in the eastern and northern portions of the state. This line served as a secondary mainline for the BCR&N, providing access to agricultural areas in northwest Iowa, southwest Minnesota and east central South Dakota. In 1900, the CRIF&NW constructed an additional 36 miles of new railroad, extending from Worthington to Hardwick, Minnesota, on the existing line. The CRIF&NW was outright purchased by the BCR&N in May 1902. The BCR&N was in turn purchased by the Chicago, Rock Island & Pacific Railway (Rock Island) in June 1903. The Rock Island operated a large railroad network through the central United States, serving diverse industries.
Between Vinton and Estherville, the Rock Island operated this line as a secondary line. The Rock Island operated the lines towards Watertown as branch lines. The Rock Island struggled financially throughout much of its history, experiencing repeated bankruptcies and chronic instability. After World War II, the Rock Island struggled to survive, proposing mergers and deferring maintenance on their routes. The railroad reorganized as the Chicago, Rock Island & Pacific Railroad in 1948. A section between Luverne, Minnesota and Kanaranzi, Minnesota was abandoned in 1962. In 1969, the Rock Island abandoned segments between Lismore, Minnesota and Watertown; between Ellsworth, Minnesota and Karanzi and between Luverne and Hardwick. By the mid-1970s, the railroad was in serious decline. The railroad secured loans to eliminate slow orders, acquired new equipment, and attempted to restore profitability. A short section from Little Rock, Iowa to Ellsworth was abandoned in 1977. In 1978, the railroad came close to profit, but creditors were lobbying for a complete shutdown of the Rock Island. During the fall of 1979, a strike crippled the railroad, and by January of 1980, the entire system was ordered to be shut down and liquidated. Many of the lines and equipment were scrapped. Profitable sections of railroad were prepared for sale. In 1980, several sections of this line were abandoned, including the Traer to Dows section; the Clarion, Iowa to Goldfield, Iowa section; the Lake Park to Lismore section section and the Sibley, Iowa to Little Rock section.
Three separate lines of this line were sold to other railroads. Between Vinton and Dysart, the line was acquired by the Iowa Northern Railway (IANR) for use as a branch line. Between Dows and Clarion, the Chicago & North Western Railway (C&NW) acquired the line as an industrial lead. Between Goldfield and Sibley, the line was also sold to the C&NW for use as a secondary line to serve agricultural industries. A short segment between Allendorf, Iowa and Sibley, Iowa was abandoned by the C&NW in 1981. It is believed that the Superior, Iowa to Allendorf segment was sold to the Iowa Northwestern Railroad (IANW) around the same time. In 1994, IANR abandoned the Vinton to Traer segment of this line. In 1995, the C&NW was acquired by Union Pacific Railroad (UP). IANW abandoned the line between Ocheyedan, Iowa and Allendorf in 2004, followed by the segment between Superior, Iowa and Ocheyedan in 2008. Today, UP operates the Estherville Subdivision between Goldfield and Superior, as well as the Dows Industrial Lead between Dows and Clarion. Three sections of the line have been reused as trails, including the segment between Vinton and Dysart as the Old Creamery Trail, the segment between Reinbeck and Holland as the Pioneer Trail and the segment between Allendorf and Sibley as the Ed Winkel Memorial Trail. An additional trail is currently being developed between Superior and Allendorf, and will be known as the Iowa Great Lakes Trail.
Located on the south side of Estherville, this steel stringer bridge carries a former Chicago, Rock Island & Pacific Railroad (Rock Island) line across Iowa Highway 4 (9th Street). In the 1920s and 1930s, the Iowa Highway Commission worked to improve highways throughout the state. As part of several projects, grade separations were proposed at busy railroad crossings. Working with the railroad companies, the Iowa Highway Commission reached agreements to construct dozens of grade separations throughout the state. In 1932, an underpass was proposed at a busy Rock Island line on the south side of Estherville. Contracts were awarded in late 1932, and work on the underpass was completed in 1933. Currently, the bridge consists of a double track 44-foot steel stringer span, set onto concrete abutments. The superstructure follows a standard design, with six beams per track, a timber ballast deck and set at a skew. The substructures also follow a standard design, with sloped wing walls. The Rock Island furnished the superstructure, which was fabricated by an unknown contractor. Snyder and Johnson was awarded the contract for the concrete abutments. Steel stringer spans were commonly used by railroads, as they were durable and easy to construct. Since the initial construction, the bridge has seen no significant alterations, and both tracks remain in use today. Overall, the bridge appears to be in fair to good condition, with no significant deterioration noted. The author has ranked this bridge as being locally significant, due to the common design.
