context_page_description: Bundesautobahn 100 is an Autobahn in Germany.
  The A 100 partially encloses the city centre of the German capital Berlin, running from the Wedding district of the Berlin-Mitte borough in a southwestern arc through Charlottenburg-Wilmersdorf and Tempelhof-Schöneberg to Neukölln. It connects with the Bundesautobahn 111 at the Charlottenburg interchange, with the A 115 at the Funkturm junction, and finally reaches the A 113 at its southeastern terminus in Neukölln, all linking it with the outer Berliner Ring A 10. The route in most parts runs parallel to the tracks of the inner circle line of the Berlin S-Bahn.
  The first section at western Kurfürstendamm was opened in 1958. According to the concept of a "car-friendly" city, the A 100 was then intended to become a ring road, but today a completion of the ring as an autobahn is no longer proposed. It is nonetheless still often called Stadtring. The section between the Funkturm and Kurfürstendamm interchanges is the busiest autobahn in Germany, with an average of 191,400 vehicles per day. Recently a planned southeastern extension to Sonnenallee and Treptower Park has been the target of various protests.
context_section_description: Starting from the center of the Britz tunnel, the middle main tracks of the A 100, with a two-lane swing, lead south to the A 113, which has been under construction since 1997. The subsequent northern section of the A 113 to Späthstraße was opened on 14 July 2004 together with the motorway junction Neukölln. Then the A 113 was extended, only in 2005 to Adlershof and following 2008 to Waltersdorf, resulting in a continuous route to the A 13 results.
  For the further construction of the A 100, the outer ramps were designed with two lanes at the motorway junction. However, these led immediately at the end of the ramps in a curve on the provisional junction Grenzallee. As part of the construction work for section 16, the direct exit to Grenzallee was closed and an exit to a bypass built.
  As a regular junction, additional ramps to the eastern side of the junction Buschkrugallee are built into the motorway junction. The western side of the junction are the tunnel accesses of the tunnel center Britz, which formed a half-junction until the opening of the triangle and the end of the A 100 were.
  As a result of the planned further construction and the integration of the junction, the motorway junction consists of six bridges in four levels, each spanning the waters of the Neukölln shipping canal. The bridges lie between the port Britz-Ost and the harbor Neukölln.
