Paralleling the Mohawk River from a distance, NY 46 soon reaches a junction with the northern terminus of NY 274. At NY 274, NY 46 turns northward near the abandoned Black River Canal and crosses through the hamlet of Frenchville before reaching North Western. Running between the river and Buck Hill, NY 46 begins a northwest route through the town of Western, but changing directions at the hamlet of Hillside, where a connector to Western Hill Road (CR 76) is provided. Now running northward, NY 46 returns to the rural settings north of North Western and soon reaches the rural hamlet of Dunn Brook. Just north of Dunn Brook, the route crosses the town line from Western into the town of Ava. The stretch of NY 46 in Ava is very short and after one curve, the route crosses into the town of Boonville.
