North of Elmora, Route 439 intersects with CR 610 (West Grand Street) and Route 28 (Westfield Avenue), both of which parallel each other for several miles. After the intersection with Route 28, the highway begins the turn to the east once again. At an intersection with Chilton Street, the highway changes monikers to North Avenue, which it retains for the remaining length. During the curve, Route 439 enters Union and intersects with the southern terminus of Route 82, where Kean University and Phil Rizzuto Park both surround the highway. After Route 82, the highway enters Hillside and begins the eastward progression, passing to the south of Elizabeth River Park. After the curve completes, Route 439 enters Elizabeth again and intersects with County Route 623 once again and continues a short distance, where it terminates at the second intersection with Route 27. North Avenue continues eastward to an interchange with Route 81.
