Located just east of Kellogg, this small deck girder bridge crosses Coon Creek near Illinois Avenue.
Built in approximately 1893, the bridge features a twinned deck girder span set onto concrete abutments.
Twinned deck girder spans are rather common on railroads. However, some were originally constructed as such, while others were rebuilt at a later date using scrap material.
It appears that this structure was originally constructed using twinned deck girders. However, a lack of bridge information for the Rock Island will likely prevent ever knowing a true build date. Currently, the 1893 date was provided as an estimate by the ICC Valuation records at the National Archives.
Overall, the bridge appears to be in fair condition. The substructures of the bridge have begun to accumulate severe deterioration, while the superstructure has no visible serious deterioration.

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