Through the Niagara Region, the route is designated as the Niagara Wine Route, and while well-signed, exists in the form of loops and spurs connecting the various wineries to the communities of the region.[1] The trunk route follows Regional Road 81 from Grimsby eastward, where in West St. Catharines it diverges into two primary North and South routings. The first route travels north along Regional Road 34 where it then turns east, huging the shore of Lake Ontario along Regional Road 89 and passing through Port Dalhousie and many of the wineries along the lakeshore. The other route pass along the edge of the Niagara Escarpment and southern Niagara-on-the-Lake along Regional Roads 69, 100 and 55. A spur along Fourth Avenue and Ontario Street connects wineries in the west-end of city and downtown St. Catharines to the northern route, while another spur crosses through central Niagara-on-the-Lake and the community of Virgil, connecting both the North and South routes to the Niagara Parkway . Both trunk routes re-connect in the Olde Town of Niagara-on-the-Lake where Regional Roads 89 and 55 meet, not far from the mouth of the Niagara River.
