Notes
Survey number HAER NC-32
Building/structure dates: 1919 initial construction
Significance: Built by the Virginia Bridge and Iron Company for the Southern Power Company, the bridge is 300 feet long and is divided into sixteen panels. It is the only bridge of this length and configuration in the United States. Its members are heavy and proportioned to its length. The chord members are three times the size of a typical 120-foot Pratt Through Truss. At the time of construction, 1919, this bridge was somewhat of an engineering feat. The bridge had to be constructed of short members that could be trucked over the unimproved roads in the mountainous region and assembled to form each of the 43' x 300' trusses. This system depended on newly-developed technology of field riveting, which determined the strength of each joint and ultimately the entire structure.
