A brief history of the Chicago & North Western Iowa Division mainline, now part of the Overland Route:


This interesting looking stone arch is located near the US-65 Overpass in Colo.
Built in 1890 and later widened in 1900, the bridge is simply composed, with a single small stone arch.
The stone arch has one unique feature, which is the massive headwalls. This is an uncommon feature.
Overall, the bridge appears to be in good condition.

The author has ranked this bridge as being locally significant, due to the unique feature and the age of the bridge.
