North Avenue is a north/south route in New Rochelle. It becomes a county route at Huguenot Street (US 1) and runs north to Wilmot Road, where it curves to the west and becomes Mill Road (CR 82). The entire length is a two- to four-lane undivided road with traffic lights. While the name is consistent along the entire length, North Avenue has two route numbers. South of Eastchester Road, North Avenue is designated CR 81; north of Eastchester Road, it is designated CR 101. Also, while North Avenue is assigned a county route number (or two of them, as the case may be), it is not maintained by the county.
