The line crossed across the Big Sioux a number of times, crossing between Iowa and South Dakota.
The line was merged into the Sioux City and Dakota Railroad in 1879.
By 1881, the line became a branch of the Chicago, Milwaukee & St. Paul Railway, also known as the Milwaukee Road.
In 1913, following an escapade to the Pacific Ocean, the railroad became known as the Chicago, Milwaukee St. Paul & Pacific Railway.
Heading north out of Sioux Falls, the Milwaukee Road also operated a branch to North Dakota.
By 1981, with the Milwaukee Road falling to bankruptcy, the Dakota & Iowa (D&I) Railroad was formed as a joint coalition between Iowa and South Dakota to operate the former branch to Sioux City.
Today, D&I continues to operate the line from Sioux Falls to Sioux City, as well as the Dell Rapids branch.
This bridge is a unique structure. The bridge features a center 8 panel riveted warren pony truss, which is extremely heavily built.
This design has been found in two other places. One being just south of here in Hudson, and the other being in the middle of Minnesota, in Steele County.
The story and records pulled indicate the given build date. The bridge was originally built with Through Girder main spans in 1905, and contained C-4 Through Girder Spans added in 1911.
The C4 spans were likely destroyed in 1915 flooding, and replaced with some sort of span. The massive pony truss was installed in 1932.
The approaches were rebuilt using I-Beams in 2014, after flooding damaged the bridge.
The piers are a combination of wood and concrete. The photo above is an overview.
The Big Sioux Valley features some beautiful areas, including this.
