Located northwest of Richland, this standard concrete viaduct was built to cross 300th Avenue.
Built in 1910, the bridge consists of a single concrete slab span, set onto concrete abutments. This design was a standard on the Chicago-Kansas City leg of the Milwaukee Road, and was commonly used for small creeks and roads.
reinforced concrete viaduct
Typical reinforced concrete viaduct and possibly this bridge. From Railway Engineering & Maintenance of Way; May 1912.

While this bridge was originally built to cross 300th Avenue, the road was rerouted in 1936 and the land turned over to adjacent landowners.
Overall, the bridge is in fair to poor condition. Significant spalling has begun on the structure.

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