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 one of the longer ones across the Big Sioux River. It is 805 feet, the trestle approach making up a majority of it.
The main span is a 125 foot, 6 panel pin connected pratt pony truss, reported to have been built in 1914.
The main span may have been located here in 1914, however it looks older. The pilings on some of the approaches are steel, a product of 2014 repairs.
South of the pony truss, the bridge features a single deck girder.
The bridge also rests on wooden pilings. The photo above is an overview from the south bank.
