Located near Heron Lake, this large through girder bridge carries the former Chicago, St. Paul, Minneapolis & Omaha Railway over Jack Creek alongside Minnesota Highway 60. The first bridge at this location was a timber pile trestle. During the early portion of the 20th Century, the Omaha Road spent significant capital upgrading this route, including replacing timber bridges with steel structures. In 1910, the original trestle bridge would be replaced with the present bridge. The bridge consists of a 60-foot through plate girder span, approached by two 38-foot 9-inch through plate girder spans on the south end. The entire bridge is set onto concrete substructures. The 60-foot span uses a standard C&NW/Omaha Road design, with a traditionally composed floor and rounded and tapered ends. The approach spans also use a standard design, but use squared ends and shallower girders. Minneapolis Steel & Machinery Company fabricated the superstructure, while an unknown contractor constructed the substructure. Through plate girder spans were commonly used by railroads, as they were durable and easy to construct. Overall, the bridge appears to be in fair to good condition, with no significant deterioration noted. The author has ranked the bridge as being locally significant, due to the common design.
