In 1898, the Fort Dodge and Omaha Railroad began construction of a new line, linking a Dubuque & Sioux City Railroad (Illinois Central) line at Tara, Iowa to Omaha, Nebraska.

This new line would be completed in a staggering 208 days, opening in early 1899. The line was owned by the D&SC (which was a subsidiary of Illinois Central).
The line was also the most significant branch off the D&SC mainline through Iowa.

The new line connected mainly rural areas, and crossed into Omaha on a swing bridge over the Missouri River.
This bridge was leased from the Omaha Bridge and Terminal Railway Company.

When completed, the line was regarded as a mainline, connecting Nebraska to Chicago. East of Tara, the line connected Waterloo, Dubuque and Chicago.

By 1947, the IC fully absorbed any remains of the Dubuque & Sioux City Railroad. IC became the sole operator and proprietor of this line.
In 1972, the Gulf, Mobile & Ohio merged with IC to form the Illinois Central Gulf.

In 1985, operations of the ICG western division (west from Chicago) was spun off into the Chicago Central and Pacific Railroad.
By 1996, the railroad was repurchased by Illinois Central. Canadian National Railway purchased Illinois Central in 1999, and continues to operate the line as the Omaha Subdivision.

Located between Logan and Woodbine, this concrete slab bridge crosses Perry Trail near the ghost town of Willett.
Built in 1917, the bridge consists of a single concrete slab span, set onto concrete substructures. This type of bridge is exceptionally common for underpasses.
The road underneath makes a sharp turn at this bridge, leading to a very muddy area underneath the bridge.
Overall, the bridge appears to be in good condition, with no significant deterioration noted.

The author has ranked the bridge as being locally significant, due to the common design.
