As NY 840 approaches the residential outskirts of Utica, it connects to Middle Settlement Road (CR 30) by way of a Partial cloverleaf interchange. East of the junction, the route curves southeastward and enters a major commercial district, where it intersects NY 5A by way of a single-point urban interchange. The district is confined mostly to the vicinity of NY 5A, however, and NY 840 proceeds southeast through residential neighborhoods and around pockets of commercial development to a cloverleaf interchange with the North–South Arterial (NY 5, NY 8, and NY 12) near the southern city line of Utica. NY 840 ends here; however, the highway continues southeast through the interchange as NY 8.
