Bundesautobahn 115 is an autobahn in Berlin, Germany. It connects the Berliner Stadtring with the Berliner Ring, using parts of the old AVUS race track. AVUS was opened in 1921 as Germany's first limited access road. After World War II, the A 115 served an important function as a transit road between West Berlin and West Germany. In 1969, a small part of the autobahn was moved eastwards by GDR authorities so that the Checkpoint Bravo border crossing at Dreilinden would be fully on West Berlin territory.
