In 1859, the Chicago, Iowa & Nebraska railroad built from Clinton, Iowa on the Mississippi River, to Cedar Rapids, Iowa which is on the Cedar River.
At the same time, the Cedar Rapids and Missouri River Railroad charted a line continuing from Cedar Rapids to Council Bluffs, on the Missouri River.

The entire line across Iowa was complete by 1867. It connected to the Mississippi and Missouri Railroad. This was a critical link in the very famous Transcontinental Railroad.

By 1884, the railroads east of the Missouri became part of the Chicago & Northwestern Railroad system. The construction of this line was one of the most important developments to the economy of Iowa.
As a bypass for Cedar Rapids, the Linn County Railway built a bypass in 1887. This route has since become a part of the mainline, as opposed to the bridge through downtown Cedar Rapids.

Due to the increased traffic along the route, it would be double tracked. The first segment to be double tracked was a segment between Cedar Rapids and the Cedar County Line.
That segment, and another through Clinton County were completed in 1891. A segment through Cedar County was double tracked in 1894.

The remainder of the line between Boone and Clinton was double tracked between 1898 and 1902.

The Chicago Northwestern became part of the Union Pacific Railroad in 1995, who favors this route, calling it the Overland Route. It sees a max of 100+ trains/day and is operated as the Clinton Subdivision between Boone and Clinton.

The Clinton Swing Bridge is the heaviest used bridge across the Mississippi. The swing span is the largest ever erected, and it was the first electrified swing bridge.

This bridge contains four spans. A deck girder span, a Swing Span, a Parker Through Truss span and a Quadrangular Through Truss Span.

The bridge is planned to be replaced in 2018 by a high bridge further downstream. Currently, the bridge opens and closes almost 150 times a day.

The bridge is on all masonry substructures. The abutments are extra wide for a third track, which was the old bridge.

The C&NW engineered some of their own trusses. The main span was one of them.
