Located below the Union Pacific Bridge, this small beam bridge crosses an unnamed ditch.
Built in approximately 1940, it is likely that this span replaced a pile trestle. It consists of a standard steel stringer, set onto concrete substructures.
There are little notable features on this bridge, and no date could be found. It appears the bridge is in good condition.

The author has ranked this bridge as being minimally significant, due to the common design and small size.
The photo above is an overview, with the bridge partially obscured by a stone pier.
