In 1861, the Northern Illinois Railroad began construction of a line that would run from Savanna, Illinois to Racine, Wisconsin, including a segment from Lannark to Kittredge, in Illinois.

In 1862, the line would be extended again to Savanna, on the Mississippi River.
The line would beconme part of the Western Union Railroad in 1865.

In 1875, the Chicago and Pacific Railroad would begin building west from Halsted Street in Chicago, and reach Byron, Illinois; seated on the Rock River.

By 1880, with the lines becoming heavily profitable the Chicago, Milwaukee & St. Paul Railway took over the lines, although allowing the railroads to operate as subsidiaries.

Also in 1880, the lines would be connected. A new piece of track connected Byron and Kittredge.
In addition, the railroad built a new bridge across the Mississippi River at Sabula, Iowa to connect to the empire in Iowa.

The railroads became fully owned by the Milwaukee Road in 1900, and double track work commenced from Chicago that year, and made it as far as Sabula by late 1905.
The railroad became known as the Chicago, Milwaukee St. Paul & Pacific in 1913, as the pacific expansion began to near completion.

The line became one of the most important for the Milwaukee Road, connecting Chicago to Elgin, Byron and Savannah. In addition, the line connected to Council Bluffs in Iowa, making a regional connection.

While much of the line is still intact, a part from Goose Island to Halsted Avenue in Chicago was removed in the 1970s.
Also in Chicago, the line from Ashland Avenue (near the Kennedy Expressway) to a junction with the main line to Saint Paul near Monticello Avenue became a trail in 2015, after abandonedment years later.

The Milwaukee Road disolved in 1985, merging with Soo Line, and eventually Canadian Pacific Railroad.
Canadian Pacific in turn sold the line to I&M Rail Link in 1997, which became the Iowa, Chicago & Eastern in 2002, and Dakota, Minnesota & Eastern Railway later that year.

The DM&E was purchased by Canadian Pacific in late 2008. The line is known as the Chicago Subdivision, and sees a fair traffic base.

Located near Leaf River, this large deck girder bridge crosses the river of the same name.
Built in approximately 1920, the bridge was originally constructed with four spans of double track deck girder. However, the second track was removed sometime after the fall of the Milwaukee Road. In addition, the outer spans were reconstructed with precast concrete spans in 2012. The bridge rests on stone, concrete and steel pile piers.
The girders are fairly heavy for the time period. It is unknown why the second track was removed, although it is possible that these spans were reused somewhere else.
Overall, the bridge appears to be in good condition. No major deterioration was noted, and the substructures appear to be in excellent condition.

The author has ranked this bridge as being locally significant, due to the common design.
