After leaving the village of Dannemora, the route heads to the southeast and back into the forests of the Adirondack Park. NY 374 continues eastward, progressing to the north of downtown Cadyville. The highway turns to the northeast once again, entering Cadyville, where the route approaches an interchange with NY 3. At this interchange, NY 374 becomes a bypass, remaining a two-lane route with at-grade intersections with local roads, like Rand Hill Road, as it bypasses Cadyville and West Plattsburgh, paralleling NY 3. After West Plattsburgh, NY 3 curves to the southeast to intersect NY 22B, and NY 374 remains on an eastern track, intersecting NY 190, which intersected back in Brainardsville. Remaining a two-lane arterial, the road parallels other main east-west roads like Tom Miller Road (CR 26), NY 3 (Cornelia Street) and Rugar Street. Just before its final junction with NY 22, the road widens to a divided four-lane highway in preparation for the nearby junction of Interstate 87 and curving into one-way streets in the city of Plattsburgh.
