This standard Warren Through Truss stood for many years, until it was replaced in 2017.
Originally built with one track in 1897, the bridge was expanded in 1901. The original 1897 span was a riveted Quadrangular Through Truss, which was replaced by the Warren Through Truss structure in the 1940s. This span was likely built approximately 1905 at an unknown location.
The added span was a 6 panel, riveted Warren Through Truss. The design is standard along Rock Island routes. In addition to the trusses, each span was approached by a small deck girder span. The bridge rested on concrete substructures.
While the 1901 span was removed in the 1990s, the warren span lasted until 2017.
Unfortunately, Iowa Interstate Railroad has decided to replace the number of trusses along their route. This truss was the first replaced, in the spring of 2017.
The author wishes a more historical preservation friendly approach would have been taken to preserve the bridge at this location.
The author has ranked this bridge as being moderately significant, due to the bridge having been one of a dying amount of trusses in Iowa.
