Distant View To North Northwest. Subject Bridge And Its Setting
This bridge seems to be of a rather standard design used by the Chicago & Northwestern Railroad. Several extant examples of pony truss bridges, built by the C&NW, are located in Iowa.

You probably don't want to try to find this bridge using the GPS coordinates because they seem to be off slightly. On my map, these coordinates put the bridge somewhere north of Hudson Bay, near the arctic circle.
