A detailed record of the construction of the bridge by F J Haynes who had recently been appointed the official photographer of the railroad. The bridge was a wooden trestle design of 1500 feet in length between four stone piers in the river. It utilized a combination Whipple truss and bowstring trusses at the landings. The two main spans saw sections of the truss assembled on land and then floated and lifted into place for assembly. Morison DAB XIII 191-192 had previously designed and built a number of bridges for the Erie Railroad under the direction of its chief engineer Octave Chanute. He was however at this time an independent contractor and this was his most sophisticated individual effort. He would go on to complete several more bridges across the northern United States amassing an astonishing record of successful crossings of most difficult environments. Haynes carefully photographed the most salient features of the multi-year construction providing a superb - possibly unique - engineering record of the construction work.
