This small concrete box culvert crosses a field drainage creek south of Sheldahl, Iowa.
Built in 1914, the bridge features a reinforced concrete box culvert span, at a standard length of 6 feet. It is likely that this culvert replaced a wooden trestle.
These types of culverts are exceptionally common for cattle passings and small drainage areas. Nearly every rail line in America used some variant of a box culvert.
Overall, the bridge appears to be in fair to good condition, with little deterioration noted. It is currently used as the High Trestle Trail.
The author has ranked this bridge as being minimally significant, due to the common design.
