Constructed by S. DeGraff of Syracuse, New York, 1867–69, the Whipple Cast and Wrought Iron Bowstring Truss Bridge over Norman's Kill in Albany, New York, is a very well preserved Example of a Whipple Bowstring Arch Truss, still in daily use, with no posted weight limits. Due to the sleek appearance, many users think it is a modern bridge. (The Delaware Turnpike once ran through both neighborhoods until 1929 with the construction of a new much higher, longer, and wider Delaware Avenue Bridge over the Normans Kill. This allowed commuters to and from Albany to bypass both Normansvilles. The original Whipple Bowstring bridge still stands, though it has been closed to vehicular traffic since January 1990.)
He died March 15, 1888, in Albany, New York, US and was buried in Albany Rural Cemetery, Menands, New York.
