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".
Potosi, Wisconsin
Local road signs herald Potosi's Main Street as "the longest Main Street in the world." A newspaper article traces the claim to a 1950s item in "Ripley's Believe It Or Not" which made the more qualified statement that it is the longest Main Street "without a cross street." Current maps show a three-mile stretch, with numerous streets—including one named "Cross Street"—that drain into it and end, forming T-shaped intersections, but no street that continues across it. The stretch is divided into two portions each with a distinct street name: North Main Street and South Main Street.
