The A 9 towards Berlin am Dreieck

The Bayreuth / Kulmbach motorway triangle (also Bayreuth / Kulmbach triangle , abbreviation: AD Bayreuth / Kulmbach ) is a motorway triangle in north-east Bavaria in the Upper Franconia administrative region . The federal motorway 70 ( Schweinfurt - Bayreuth ) ends here at the federal motorway 9 ( Berlin - Leipzig - Munich ). At the Bayreuth / Kulmbach motorway triangle, Europastraße 48 changes from the A 70 to the A 9 towards Berlin and runs there together with the Europastraße 51 coming from Munich .

geography

The border between the municipality of Harsdorf , which lies to the west of the structure, and the town of Bad Berneck , which is to the east, runs through the triangle . Nearby places are Nenntmannsreuth , Altenreuth and Zettmeisel . It is located about 10 km north of Bayreuth , 40 km southwest of Hof and 55 km east of Bamberg .

The Bayreuth / Kulmbach motorway triangle has junction number 40a on the A 9 and number 26 on the A 70.

Design

The motorway triangle is now a complete triangle . Before it was rebuilt in the 1990s, it had the left-hand trumpet design. A special feature is the connecting lane between the semi-direct ramps Bamberg – Berlin and Munich – Bamberg. It was necessary because the Munich – Bamberg ramp branches off the A 9 before the Bindlacher Berg junction and therefore the possibility of continuing towards Berlin had to be preserved . In this respect, the Dresden-Nord motorway triangle has a similar design.

The triangle forms a double junction on the A 9 with the Bindlacher Berg exit.

In order to establish the connections between the motorway sections, four motorway bridges were built. In the north and west of the triangle, two municipal roads bridge the building.

history

Construction of the motorway from the triangle began in November 1937, but work had to be stopped in September 1939 due to the Second World War . It was not until 1958 that the first two-lane carriageway to Unterbrücklein (Kulmbach / Neudrossenfeld junction) was released. The second lane was released on October 1, 1970.

Earlier names for the motorway triangle were Dreieck Kulmbach and Dreieck Nenntmannsreuth . The current name of the building is derived from the cities of Bayreuth and Kulmbach , which are located near the triangle.

Traffic volume

In 1978, 7,500 vehicles were registered at the triangle.
