This bridge is the longest known surviving cast and wrought iron bowstring truss span in the United States and is the second longest in North America, with only the Blackfriars Street Bridge in Ontario being longer. Unlike the Blackfriars Street Bridge however, this bridge enjoys a nearly complete lack of alteration, which is a remarkable achievement for a bridge from the 1870s. Its age, design, lack of alteration, and span length all combine to make this one of the most important historic bridges in the United States. The bridge is currently abandoned and its future is uncertain. It is paramount that this bridge be given the absolute highest preservation priority. The bridge could, if desired, be relocated and reused at a new location. Although maintaining a bridge in its original location is desirable, this bridge's technological significance would not be diminished in a new location. To maintain the bridge's excellent historic integrity, it is important that any preservation work done on the bridge follow the latest techniques of restoration, focused on maintaining original bridge material, employing historical construction methods like riveting, and replicating exactly any parts that must be replaced.
