This steel stringer bridge crosses 5th Street (Iowa 122, formerly US-18) in Mason City.
Built in 1958, the bridge features a pair of steel stringer spans, which behave as a deck girder. The bridge rests on concrete substructures.
While this bridge is now a trail, a railroad bridge sits parallel.
Overall, the bridge appears to be in good condition. A Chicago & North Western herald has been painted over.
The author has ranked this bridge as minimally significant, due to the common design and newer age.
