Yonge Street
Provincial downloading separated Yonge Street from Highway 11 during the 1990s. As a result, Highway 11 does not start until Crown Hill just outside Barrie, several kilometres north of where the name "Yonge Street" ends. The Guinness Book of World Records no longer lists Yonge Street as the longest street in the world and has not chosen a replacement street, but cites the Pan-American Highway as the world's longest "motorable road".
