It is one of only two surviving camelback trusses in New York State, and the only single-span one. It is also the only surviving camelback built by the Groton Iron Bridge Company, and it remains unaltered in its rural setting.","narrative":"Spanning the Genesee River in the hamlet of Caneadea, this 246-foot steel truss bridge carries East Hill Road (County Road 46) on cut stone abutments. Built in 1903 by the Groton Iron Bridge Company of Tompkins County, it replaced an earlier bridge washed away by a flood in 1902. Its camelback Parker design, a variation of the Pratt through truss, has a polygonal top chord with five distinct slopes. The bridge keeps its lattice portal bracing, original metal cresting and decorative plates naming the bridge company and former town officials. Its open steel grate deck is unchanged, and the road is now closed to traffic. A statewide survey found only two surviving camelback trusses among eleven remaining Parker metal truss bridges in New York. This one is the earliest and longest of the two, the only single-span example, and the only surviving camelback by its builder. These qualities, along with its unaltered rural setting, led to its recognition for engineering significance.","period_of_significance":"1903","architect_builder":"Builder: Groton Iron Bridge Company","architectural_style":"OTHER/Camelback Parker Truss","criteria":["C"],"status_note":"The road across the bridge is currently closed to traffic, and the bridge is listed as not in use.
