The Bundesstraße 96a (B96a) is a federal highway in Germany. It begins in Mahlow south of Berlin on the B96 and ends north of Berlin in Birkenwerder, again on the B96. In the GDR it replaced the route of today's B96 running through West Berlin. In the GDR it was called F 96 and after German reunification was renamed B96a.
Until the construction of the bridge over the Berlin outer ring two kilometers west of Waßmannsdorf in the 1980s, today's B96a did not begin in Mahlow, but in the Glasow district, led via Selchow to Waßmannsdorf and from there—since the early 1990s in four lanes—to the airport in Schönefeld.
With the planned expansion of Berlin-Schönefeld Airport into an international air hub (BER), old plans were taken up again and revised. In 2002 the four-lane link from the northern bypass of Mahlow to the bridge with the Berlin outer ring was expanded. Since 2007, the expressway from there via Waßmannsdorf to Schönefeld has been passable with four lanes throughout.
The Berlin-Schönefeld Airport had already been connected to East Berlin in four lanes. From the Treptow junction on the A 117 motorway, the route continues as a motor road without intersections and ends at the broad Adlergestell, which leads into the city of Berlin.
