Notes
  • Significance: Roaring Run is one of the oldest surviving bridges of its type (Bowstring Truss Bridge) in the United States. / This highway bridge, fabricated by King Iron Bridge and Manufacturing Company of Cleveland, Ohio, is one of the few surviving bridges of this type currently utilized on public highways. The 55-foot span incorporates cast iron, rolled wrought iron, and riveted wrought iron plates in its construction. The structure is patterned after the bowstring truss bridges patented by Squire Whipple in 1841, but incorporates fabricating modifications resulting from the advance of building technology over a period of 30 years. It is conjectured that the structure was erected in the mid 1870's.
