Located between Andover and Groton, this simple concrete slab span crosses 413th Avenue south of the intersection with US-12.
Built in 1913 during a line change and double tracking project, the bridge features a single concrete slab span. The bridge is strictly functional, with no decorative features.
This type of span is a simple design, commonly used along this line and others in the Milwaukee Road system 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, although not as severe as other nearby bridges.
When the author visited this bridge, it was right after a major snowstorm. Evidence of this can be seen in the above photos. The snowdrifts around this bridge were impressive.

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