The next year, another 20 mile segment from Marengo to Brookyln opened. By 1864, the route opened to Kellogg, located in Jasper County.
In 1866, the Mississippi and Missouri Railroad was purchased by the Chicago, Rock Island & Pacific Railroad. The Rock Island completed the route into Des Moines by 1867.
While the route continued to Council Bluffs to the west and Chicago to the east, this middle segment of the route was equally as important. It opened up expansion and gave the Rock Island many connections to other railroads.
Due to the popularity of the route, much of it was extensively rebuilt between 1899 and 1901. While most of this segment would never be double tracked, the biggest project was building new bridges.
Despite the efficiency and popularity of this route under Rock Island, the Rock Island began seeing serious financial troubles as soon as the end of World War II. As a result, the railroad entered its final bankruptcy in 1980 and the property was liquidated.
In 1981, the Iowa Railroad Company began operating this line between Council Bluffs and Bureau, Illinois. Despite the birth of a short line railroad, shippers questioned the ability to effectively move goods.
As a result, the Iowa Interstate Railroad was born in 1984. Since the conception, the railroad has become well known and respected in Iowa. Presently, this route is known as the Third Subdivision.

Utilizing a common design, this bridge crosses over Little Bear Creek between Carnforth and Victor.
Built in 1892, the bridge is one of the larger crossings of Little Bear Creek. While the girders date to 1892, each span contains four girder lines, typically indicative of a secondhand or strengthened bridge. It is unknown if that is the case here.
The substructures of the bridge utilize both stone and concrete. These have likely been rebuilt since 1892.
Overall, the bridge remains in a good condition.
Despite being a common design, the author has ranked the bridge as being moderately significant due to the older age of the bridge.
The photo above is an overview. The bridge can be accessed from nearby roads.
