This bridge is a rare example of a double-intersection Warren truss bridge in Iowa. Double-intersection Warren truss bridges are rare in most of North America, however New York State and Ontario are two areas where the configuration is more common. Located far away from those areas, this bridge is rare both on a statewide basis and a greater regional basis as well.
The bridge is also rare for the early use of all-bolted connections. Although some of the bolts appear to have been replaced, the use of bolts for all connection points does appear to be an original detail, and is thus significant. Riveted connections were the standard during the period in which this bridge was built, which was likely in the 1895-1915 range, with the 1900-1910 range bring most likely.
The bridge superstructure appears to be in good condition overall. Some sections of the bottom chord appear to be bent from flood damage, but section loss and pack rust is minimal. The bridge has been closed to traffic for some time. If closure was due to structural deficiency, it would appear that such deficiency is isolated, since the overall bridge appears to be in decent condition. Restoration of this bridge either for light vehicular use or pedestrian use only should be both feasible and very cost effective. Given the significance of this structure, as well as a limited number of historic bridges in the county, the bridge should be given preservation priority.
