Highway
Major highways are often named and numbered by the governments that typically develop and maintain them. Australia's Highway 1 is the longest national highway in the world at over and runs almost the entire way around the continent. China has the world's largest network of highways followed closely by the United States of America. Some highways, like the Pan-American Highway or the European routes, span multiple countries. Some major highway routes include ferry services, such as U.S. Route 10, which crosses Lake Michigan.
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.
