They formed the subsidiary Worthington & Sioux Falls Railway to construct the approximately 50 mile segment of main line from Agate Junction (near Worthington) to Sioux Falls, South Dakota.
It opened to Adrian, Minnesota by 1875, Luverne, Minnesota in 1876 and Sioux Falls in 1878.
In 1879, it would be continued west by the Chicago, St. Paul Minneapolis & Omaha Railway, reaching Mitchell by 1882.
In 1882, the CStPM&O became a subsidiary of the Chicago & North Western Railway.
The Chicago & North Western operated this line as a branch line, until 1888, when it abandoned the whole Agate Junction to Mitchell segment.
The Buffalo Ridge Railroad Authority stepped in and purchased the line from Buffalo Ridge, through Sioux Falls to Agate the same year.
In 2015, the Minnesota Southern operates from Valley Junction to Agate, where it meets a Union Pacific mainline.
In addition, the Ellis & Eastern Railway serves from Brandon to Sioux Falls.

Located in the heart of Sioux Falls, this bridge is one of several such structures in the area.
Built in 1893, the bridge consists of a pair of Quadrangular Through Truss spans, with typical riveted connections and pedimented portal bracings.
In addition, the bridge is approached by trestle spans on either side. The entire bridge rests on stone substructures, with the approaches resting on wooden bents.
Overall, the bridge remains in relatively good condition. The bridge sees little traffic. It is hoped that someday, it can be reused for trail use.
The author has ranked this bridge as being moderately significant, due to the common design but old age.
The photo above is an overview. The bridge can easily be accessed from nearby trails.
