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.
Bundesstraße 2
The Bundesstraße 2 (abbr. B2) is Germany's longest federal highway, running some 1000 kilometres from the Polish border near Gartz to the Austrian border near Garmisch-Partenkirchen. From north to south; it passes through major cities such as Berlin, Potsdam, Leipzig, Gera, Bayreuth, Nuremberg, Augsburg, and Munich. It is largely paralleled by Bundesautobahn 9, and a small portion coincides with Bundesautobahn 952.
