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.

This line was double tracked at the turn of the 20th century. 1899 for Council Bluffs, 1901 in Ames, and 1908 for Clinton.

The city of Ames exists because of this railroad.

Perhaps some famous bridges are the Kate Shelley High Bridge in Boone (15 miles west of Ames), the Cedar River Bridge in Cedar Rapids and the Clinton Swing Bridge. All 3 will have been bypassed by 2015.

The Chicago Northwestern became part of the Union Pacific in 1995, who favors this route, calling it the Overland Route. It sees a max of 120+ trains per day.

This bridge is the eastern crossing of the Mississippi at Clinton, Iowa. The bridge is made of 11-50' Deck Girder Spans on concrete filled caissons (lally columns)

The bridge will likely be replaced in 2018 by a new bridge, as the main channel bridge is going to be replaced.

The bridge contains slots for a third and fourth track in the abutments. This is likely from the old bridge, which may have been a truss bridge, as well as a track that headed north.
