In 1887, the Chicago, St. Paul & Kansas City Railway built a 26 mile route between Oelwein and Waterloo, Iowa.
Built primarely to connect railroads at Waterloo and Oelwein, the route became part of the Chicago Great Western Railway in 1893.
The route continued to be operated as a main line for the CGW until 1968, when the CGW was purchased by the Chicago & North Western Railway.
In 1995, the C&NW became part of Union Pacific, and UP sold the line to D&W Railroad in 2002.
Iowa Northern Railway purchased the route in 2003, and has continued to operate D&W as a subsidiary since.

Located in Waterloo, this small steel stringer bridge crosses Idaho Street.
Built in 1939 and completed the following year, this bridge features a trio of steel stringer spans, set onto concrete substructures. The bridge contains a few decorative features, and has a ballasted deck.
Bridges like this were common as grade separations, due to the durability and ease of construction.
Overall, the bridge appears to be in good condition.

The author has ranked this bridge as being minimally significant, due to the common design and newer age.
