Utilizing a common design, this bridge features a I-Beam bridge to cross County Road D36, a previous alignment of US-20.
Located in Moorland, the single I-Beam span is set onto wooden substructures and approached by trestle spans.
This design is common on branch lines and even some main lines to cross roads, railroads and waterways.
The author has ranked the bridge as being minimally significant, due to the common design of the bridge and newer age.
