Its eastern terminus is at a junction with NY 376 in the Poughkeepsie hamlet of Red Oaks Mill.
Jurisdiction of the highway was transferred to the state of New York in 1980, at which time it was designated NY 113.
West of the interchange, NY 113 continues south as Spackenkill Road into the IBM Poughkeepsie main plant.
Just before an intersection with Cedar Avenue (County Route 74 or CR 74), NY 113 passes by Spackenkill High School.
[citation needed] In the 1960s and 1970s, there were talks of building a north-south highway on Long Island between Port Jefferson and Westhampton Beach.
