Located between Marvin and Summit, this simple concrete slab span crosses 462nd Avenue (county Road 5) 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. The bridge features a few decorative features, unusual for such a common span.
This type of span is a simple design, commonly used along this line and other Milwaukee Road lines due to the cheap and efficient construction.
Overall, the bridge appears to be in fair to poor condition. Some spalling and cracking can be seen throughout the bridge.
When the author visited this bridge, it was soon after a massive blizzard hit the area. As a result, major snow drifts can be seen pushed up against the bridge, obscuring areas of the bridge. This was one of the only plowed gravel roads in Grant County at the time.

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