In 1871, the Chicago, Dubuque and Minnesota Railway began construction of the line from River Junction, Minnesota to Dubuque, Iowa.

At the same time, the Chicago, Clinton & Dubuque built from Dubuque to Sabula Junction. Combined, this line created a considerable sized line, able to connect to Saint Paul and Milwaukee from the North, and Chicago, Cedar Rapids and Davenport on the South.
Combined, the lines totalled 180 miles along the Mississippi River.

By 1880, both lines became part of the Chicago, Milwaukee & St. Paul Railway. They operated this as a mainline, as they understood the importance of the connection.

In addition, the line extended to Davenport and eventually Kansas City.

In 1913, pending the pacific extension, the road name was lengthened to the Chicago, Milwaukee St. Paul & Pacific Railway (Milwaukee Road).

With the Milwaukee Road struggling heavily in the 1980s, they were purchased by the Soo Line in 1985. The Soo became part of the Canadian Pacific in the same year.
In 1997, the Canadian Pacific sold this line, and many others to the I&M Rail Link, which couldn't turn a profit. They were reorganized into the Iowa, Chicago & Eastern in 2002, which became affiliated with the Dakota, Minnesota & Eastern.

In 2008, the DM&E became part of the Canadian Pacific again, who currently operates it as a subsidiary. It is currently known as the Marquette Subdivision.

Located north of Marquette, this large truss bridge crosses Paint Creek near Great River Road.
Built in 1901, likely to replace an older wooden trestle, this bridge features a pair of 6-panel pin connected Pratt Pony Trusses. These trusses rest on concrete substructures, and follow a standardized design for the Milwaukee Road. A single deck girder span also approaches the bridge on the north end.
While most of the trusses along the La Crescent-Kansas City route have been replaced, this one is a survivor. Because of the tall clearances, it is likely this one has not been targeted with replacement quite as much as others.
Currently, the bridge is operated by Dakota, Minnesota & Eastern. It has had little alterations since it was first constructed.
Overall, the bridge appears to be in fair condition. These structures are typically durable and last a long time with proper maintenance.

The author has ranked this bridge as moderately significant, due to the truss design.
