In 1858, the Cedar Falls & Minnesota Railroad constructed a line from Cedar Falls, Iowa to Lyle, Minnesota. The 77 mile line closely paralleled the Cedar River.

In 1896, the railroad became incorperated into the Dubuque & Sioux City Railroad. This railroad was a fully owned and operated subdivision of the Illinois Central Railroad.

In 1900, the Albert Lea and Southern Railroad extended the line to Glenville, Minnesota. This location was on the Burlington, Cedar Rapids & Northern (Rock Island) just south of Albert Lea.

The line immediately became part of the Dubuque & Sioux City Railroad.
The Dubuque & Sioux City ceased to exist, and became a full part of the Illinois Central in 1947.

The Illinois Central spun the line off to the Chicago Central Railway, a short line in 1985. The CC came back into Illinois Central in 1996.

In 1998, the Canadian National Railway gained control of the Illinois Central. Today, this line continues to be operated as the Osage Subdivision, with the portion south of Lyle, Minnesota (on the IA/MN Border) seeing steady traffic.

Located in the town of Nashua, this large concrete arch bridge crosses the Cedar River near Greenwood Avenue,
Built in 1902, this structure features six large concrete arches, set onto concrete substructures. When built, this structure was very decorative, unusual for a functional railroad bridge.
In the record flooding of 2008, this bridge almost was removed to prevent a pooling of water upstream from it. However, it was later decided to leave the bridge intact.
After the flood, some work was done on the bridge to restore it and prevent further damage. Unfortunately, between 2008 and many other large floods, the decorative features have somewhat been destroyed.
Currently, the bridge is operated by Canadian National. No long term plans have been presented for the bridge, so it is assumed to be safe.
Overall, the bridge appears to be in good condition, a surprising shift from the damage seen by other bridges across the Cedar River.
