Located between Milbank and Big Stone City, this simple concrete slab span crosses 147th Street at the intersection of US-12.
Built in 1913 during a line change and double tracking project, the bridge features a single concrete slab span, running at a significant skew. The bridge features some decorative features, unusual for such a common span.
This type of span is a simple design, commonly used along this line due to the cheap and efficient construction.
Overall, the bridge appears to be in fair condition. Some spalling and cracking can be seen throughout the bridge.

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