Spackenkill Road is an east/west route in Poughkeepsie. It begins at a grade-separated interchange with South Road (US 9) and runs east for a few miles to end at a traffic light at New Hackensack Road (NY 376) and Vassar Road (Dutchess CR 77).
The NY 113 designation for Spackenkill Road is relatively recent. Until 1972, Quogue-Riverhead Road (Suffolk CR 104) on Long Island was designated NY 113. At that time, Spackenkill Road was designated Dutchess CR 76.
