German Avenue Road
The German Avenue Road (German: Deutsche Alleenstraße) is a tree-lined holiday route that runs the length of Germany from the Baltic Sea to Lake Constance. About 2,900 kilometres long, it is Germany's longest scenic route. The project is supported by the "German Avenue Route Association" (Arbeitsgemeinschaft Deutsche Alleenstraße), whose members are the German Automobile Club ("ADAC"), the German Tourism Association, the German Forest Conservation Society and other institutions. The forestry scientist, Hans Joachim Fröhlich, was its major proponent.
The aim of the Association is to preserve, protect and maintain avenues in Germany and to restore old avenues after they were destroyed in many places in recent years by road development and safety projects. The Association says the Route connects "the East with West and North to South [and] is a symbol of German unity and common effort of the people of the old and new federal states for the protection of nature."
Cobblestones still serve as pavement on many avenues in the former East German areas. An spokesman for the Route says the average speed is about 70 km/h (43 mph).
The first segment of the German Avenue Road between Rügen Island and Reinsberg was inaugurated on 3 May 1993.
The vision for the creation of the German Avenue Road began shortly after German unification:
The German Avenue Road on the island of Rügen
Avenue on Rügen near Putbus
Ottenkreuz between Gau-Odernheim and Hillesheim
