The motorway triangle Barnim (abbreviation AD Barnim , short form: Dreieck Barnim , until 2013 the motorway triangle Schwanebeck ), before that Bernau loop or junction Penkun is a motorway triangle in Brandenburg in the metropolitan region of Berlin / Brandenburg . It connects the Bundesautobahn 10 (Berliner Ring) with the Bundesautobahn 11 ( Stettin - Berlin ) before it becomes Bundesstraße 2 .
geography
The triangle is located in the municipality of Panketal in the Barnim district . The surrounding cities and communities are Ahrensfelde , Bernau bei Berlin , Werneuchen and Zepernick , as well as the Berlin districts of Pankow , Lichtenberg and Marzahn-Hellersdorf . The closest districts are Schwanebeck , Birkholz , Lindenberg and Blumberg . It is located around 15 kilometers northeast of downtown Berlin , around 25 kilometers southeast of Oranienburg and around 110 kilometers southwest of Szczecin .
The Autobahndreieck Barnim bears on the A 10, the socket number 1, on the A 11, the number 17 on the triangle that starts Kilometrierung the Berlin ring (east clockwise).
history
New building
The Barnim autobahn triangle was built together with the first four kilometers of today's A 11 by the Berlin construction management as a branch in Szczecin . The contract for the construction was placed in April 1935, so that the earthworks began on June 6th. On November 12, 1935, the construction of the road surface began. Due to the frosty weather in the winter of 1935/1936, work was suspended for a total of 40 working days. In spite of this, the lanes were largely completed in March 1936 up to the Berlin-Weißensee junction. A Fürstenwalde-type petrol station was built there.
A total of 10,000 cubic meters of concrete and 160 tons of round bars for the bridge foundations and abutments , 1,600 tons of steel for the superstructures and 18,000 cubic meters of concrete slab were used for the 5.3 kilometer stretch from the Berlin-Weißensee junction on the Berliner Ring to Bernau-Süd on the A11 built for the roadways.
Further names of the junction were Bernauer Loop , Stettiner Dreieck , Penkuner Abzweig , Abzweig Prenzlau and Dreieck Schwanebeck.
In the 1930s, the triangle was incorporated into the Bernau Loop , on which car and motorcycle races were held until 1973. Due to the further construction of the northern Berliner Ring from the junction Berlin-Weißensee - where the racetrack ended - it was no longer possible to drive on as a circuit. In 1990 the steep curve of the racetrack was torn down.
Conversion to the Barnim motorway triangle
The Barnim motorway triangle was rebuilt and expanded from the former Schwanebeck triangle from 2011 to 2013 in six phases as part of the German Unity No. 11 traffic project . The main carriageway is now the Berliner Ring and not the direction of travel north of the Berliner Ring - A 11. The Berlin-Weißensee junction was omitted in the course of the renovation, because its function is now taken over by the southern branch of the converted motorway triangle, with the B 2 directly connected to the new one Knot was tied. At the same time the A 11 was completely expanded and rebuilt up to kilometer 2.0.
To realize the project, seven new bridges were built, some for the so-called “high-flyers”, and two bridges were renewed or expanded. In addition, 1.4 million cubic meters of soil had to be moved and 345,000 square meters of roadway built. In addition, there was a noise barrier on the ramp of the A 10 to the A 11 in the east with a length of 930 meters. The total cost of the renovation was 57.5 million euros, of which the European Regional Development Fund took over 20 million euros.
Preparatory measures, in particular clearing and marking out the route, began in spring 2010. The first groundbreaking for the renovation took place on May 5, 2011. In the first construction phase, the construction of the nine new bridge structures began in May 2011. After 29 months of construction, the motorway triangle was officially opened to traffic on November 11, 2013 under the new name Dreieck Barnim .

Design and state of development
The A 10 has six lanes throughout the area of the Barnim triangle. The completely renovated sections of the A 11 are still four-lane. The newly built section of the B 2 also has four lanes. The four connecting ramps of the triangle from the A 10 to the A 11 and vice versa have two lanes. The two direct and indirect connecting ramps from the motorways to the B 2 are single-lane. The direct integration of the B 2 results in a structural cross ( triangular design with half a clover leaf ).
Traffic volume
The Barnim motorway triangle is used by around 73,000 vehicles every day.
