For several blocks, NY 24 passes residential homes, before becoming a two-lane commercial street. A short distance to the east, the route intersects with Secatogue Avenue, which connects to the Farmingdale station to the northwest. Re-expanding to four lanes, NY 24 crosses through Farmingdale on Conklin before crossing the county line into Suffolk County. Now in the town of Babylon, retaining the Conklin Street moniker before entering an at-grade junction with NY 110 (Broad Hollow Road) in front of Airport Plaza. This junction serves as the eastern terminus of NY 24's western segment.
