For a short distance north of CR 23, NY 40 crosses through the town of Fort Ann, based near a junction with Whitney Road. The route then crosses into the town of Granville, where it enters the rural hamlet of West Granville, and a junction with CR 17 at the center. A block north of CR 17, NY 40 reaches a junction with NY 22. This junction marks the northern terminus of NY 40, whose right-of-way continues north as Sheehan Road Extension.
