Berlinka is the informal Polish and Russian name given to sections of the unfinished Reichsautobahn Berlin-Königsberg, which was a pre-World War II German Reichsautobahn project to connect Berlin with Königsberg in East Prussia. In the late 1930s, the sections near these two cities were finished, but not the larger section in between. The German demand in 1939 to run this road across the Polish Corridor with extraterritorial status and Poland's refusal to allow this was an important element in the tensions that led to the start of World War II. After the war, the German Democratic Republic, the People's Republic of Poland and the Soviet Union's Kaliningrad Oblast inherited the remnants.

The Inn Valley Motorway or Inntal Autobahn A12 is an autobahn in the Austrian federal state of Tyrol and part of Euroroutes E45 and E60.
The Reichsautobahn system was the beginning of the German autobahns under Nazi Germany. There had been previous plans for controlled-access highways in Germany under the Weimar Republic, and two had been constructed, but work had yet to start on long-distance highways. After previously opposing plans for a highway network, the Nazis embraced them after coming to power and presented the project as Hitler's own idea. They were termed "Adolf Hitler's roads" and presented as a major contribution to the reduction of unemployment. Other reasons for the project included enabling Germans to explore and appreciate their country, and there was a strong aesthetic element to the execution of the project under the Third Reich; military applications, although to a lesser extent than has often been thought; a permanent monument to the Third Reich, often compared to the pyramids; and general promotion of motoring as a modernization that in itself had military applications.
