Bundesautobahn 111 (translates from German as Federal Motorway 111, short form Autobahn 111, abbreviated as BAB 111 or A 111) is an autobahn in Germany. It connects the Berliner Stadtring (A 100) with the Berliner Ring (A 10). Before reunification, it was called the A 11. The A 111 was used from 31 December 1987 to German reunification in 1990 for transit traffic through the GDR to Hamburg and Malmö (Sweden) with the border crossing Heiligensee / Stolpe. From 1975 until reunification, the highway was designated as A 11. As part of the numbering of motorways after 1990 in East Germany then the new number A 111 was assigned. From Wikipedia
