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 southeast of Livermore, this deck plate girder bridge carries a former Chicago, Rock Island & Pacific Railroad (Rock Island) line over the East Fork Des Moines River. The first bridge at this location was likely a timber pile trestle, constructed when the line was first built. In the late 19th and early 20th Centuries, the BCR&N and Rock Island made significant upgrades to this route, replacing timber bridges with steel, stone and concrete bridges. In April 1900, the original timber bridge was replaced with a new deck plate girder bridge, set onto stone substructures. This bridge consisted of an 81-foot span on the west end and two 73-foot spans on the east end, with a lengthy timber pile trestle approach on the east end. The bridge remained in this configuration until June 6, 1972; when a derailment collapsed the two eastern deck girder spans. During the cleanup, divers determined the original center pier too badly damaged to be salvaged, and it was decided to repair the bridge with three secondhand deck girder spans, set onto the original west pier, original east pier and timber pile piers adjacent to the original center pier. The most recent alteration to the bridge came in the 1980s or 1990s, when the timber piers were replaced with new steel pile piers, giving the bridge its present configuration.
Currently, the bridge consists of a 60-foot deck plate girder span on the east end (span #1), a 36-foot deck plate girder span (span #2), a 50-foot deck plate girder span (span #3) and an 81-foot deck plate girder span on the west end (span #4). The east end is approached by 29 timber pile trestle spans. The east pier (pier #1), west pier (pier #4) and west abutment are constructed of stone, while piers #2 and #3 are constructed of steel pile bents with concrete caps. All four of the girder spans use similar but visually different designs, consisting of two plate girders and an open deck. Due to the variety of spans, it appears that the three secondhand spans were reused from separate locations. Span #1 was originally fabricated in approximately 1900 by an unknown contractor for use at an unknown location, and uses deep girders. Span #2 was originally fabricated in approximately 1900 by an unknown contractor for use at an unknown location, and uses shallow girders. Span #3 was originally fabricated in approximately 1900 by an unknown contractor for use at an unknown location, and deeper girders than span #1. Span #4 was originally fabricated in 1900 by an unknown contractor, and is the heaviest span of the bridge. The substructures follow a standard design, with rectangular piers and a west abutment with stepped wing walls. Stone for the substructures consists of a tan limestone, likely quarried at the Cedar Valley Quarry. The original substructures were constructed by an unknown contractor, while the timber and steel pile components were constructed by railroad company forces.
Railroads often reused steel and iron spans, as it provided a cost effective way to rebuild bridges without requiring large amounts of new material. At the time of the derailment, the Rock Island was struggling financially and the tracks had become deteriorated. Instead of ordering new spans, it was decided that it would be more cost effective to take three spare spans and install them here. It is likely that these three spans were moved from bridges which had been abandoned in the late 1960s or early 1970s, and were possibly stored at a material yard. It is unclear if the spans were altered, strengthened or shortened prior to installation here. Deck plate girder spans were popular for railroad use, as they were durable and easy to construct. Since the 1972 reconstruction, the bridge has seen a number of alterations. The original stringers and caps of the east approach were replaced with new timber stringers and concrete beam caps in the 1980s or 1990s. At the same time, significant repairs were made to the west abutment, including removing much of the backwall and replacing it with concrete. 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 and unknown history.
