NY 115 is a north/south route from Poughkeepsie to Clinton Corners. It begins at Baker Street (US 44/NY 55) and follows Worrall Avenue north to the city line, where it becomes Innis Avenue (CR 75). Innis Avenue ends after a little less than a mile at Salt Point Turnpike. NY 115 turns northeast onto Salt Point Turnpike. It follows Salt Point Turnpike to the Taconic Parkway, where NY 115 ends. Salt Point Turnpike continues beyond the parkway as CR 17.
The NY 115 designation in Dutchess County is relatively recent. Until 1972, Wantagh Avenue (Nassau CR 189) on Long Island was designated NY 115. At that time, Dutchess CR 17 extended south along Salt Point Turnpike to the Poughkeepsie city line.
