Located between Logan and Woodbine, this deck girder bridge crosses Parker Trail near the ghost town of Willett.
Built in 1916 using a 1903 span, the bridge consists of a single deck girder span, set onto timber substructures and approached by trestle on either side. It is unknown where the span was relocated from, but reusing spans at other locations was typical for this line.
This bridge appears to have little changes since it was first constructed. The trestle spans are of ballasted deck design.
Overall, the bridge appears to be in good condition, with no significant deterioration noted.

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