In 1850, the Milwaukee and Mississippi Railroad began construction of a line charted to connect 196 miles between Milwaukee, Wisconsin and Prairie Du Chein, Wisconsin.
By the end of the year, the railroad reached from Milwaukee to Elm Grove, and went through Wausautosa. The following year, an extension would be made another 10 miles to Waukesha.
In 1852 and 1853, the railroad built another 42 miles of track to Milton, and 18 miles from Milton to Stoughton, respectively.
Between 1854 and 1856, the railroad was extended through Madison, to Boscobel, an addition of 86 miles.
In 1858, the railroad completed to Prarie du Chein, and opened the opportunity for expansion westwards.
With a successful and mainline completed and fully operational, the M&M was purchased by the Milwaukee and Prairie du Chen Railway in 1861. In turn, the M&PdC was purchased by the Milwaukee and St. Paul Railway in 1867.
The M&StL operated numerous railroads throughout Wisconsin, and was merged into the Chicago, Milwaukee & St. Paul Railway in 1874. Known as the Milwaukee Road, the system expanded rapidly over the upper midwest.
The CM&StP later became known as the Chicago, Milwaukee St. Paul & Pacific Railway in 1915, after completing a transcontinental route.

This route would quickly be downgraded to a secondary mainline, after other routes became preferable.
While this was one of the first railroads completed, the route was sold in 1980 to the State of Wisconsin, who picked Wisconsin & Southern to operate the route. This arrangement is still ongoing in 2018.

This small I-Beam bridge is the fourth crossing of Black Earth Creek.
Built in 1930, this bridge consists of a pair of simple I-Beam spans set onto concrete abutments.
Bridges like this are standard in design, and are seen all over the railroad system. This structure replaced a wooden trestle, built in 1891.
Overall, the bridge appears to be in good condition.

The author has ranked this bridge as being minimally significant, due to the common design and newer age.
