This is a noteworthy bridge, as there are quite a few unique characteristics to it. Regardless of anything else, this is wrought iron pin connected bridge built in 1888 that is still standing, which in its own right is noteworthy.

Also notable is that it was built by the well renowned King Bridge Co., and represents only a handful of remaining bridges built by this company in New York. In a state where bridge building in this era was dominated by such regionally prolific builders as the Groton Bridge Co. and the Berlin Iron Bridge Co., this bridge was certainly an outlying example.

The Bridge employs a Whipple (double intersection Pratt) through truss, which didn't see as much use as a highway bridge. Instead this truss type found primary usage as railroad bridges, making this an uncommon (but certainly not unheard of) application. The bridge was also fabricated in the period of waning usage of this truss type, as stronger designs (such as the Baltimore and Pennsylvania) were beginning to surpass the Whipple.

Also to note is the skew angle of this bridge, which is an early application of a skewed truss. While also not unheard of, it is uncommon in this era and also makes the bridge notable.
