Located in north of Algona, this steel stringer bridge crosses 250th Street (County Road B30).
Built in 1940 to replace a trestle bridge, this structure features a steel stringer span, approached by trestle. The entire bridge is set onto timber substructures.
Currently, the bridge remains in the original configuration. This type of bridge is common to cross small waterways and roads. Little other updates have been made since the original 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.
