The Ahlhorner Heide motorway triangle (abbreviation: AD Ahlhorner Heide ; short form: Ahlhorner Heide triangle ) is a motorway triangle in Emstek, Lower Saxony, in the northwestern metropolitan region . It connects the federal highway 29 ( Wilhelmshaven  - Ahlhorn ) with the federal highway 1 ( Heiligenhafen  - Hamburg  - Cologne  - Saarbrücken ).

geography

The junction south of the Ahlhorn district in the district of Oldenburg , which belongs to the community of Großenkneten , is located in the area of ​​the community of Emstek in the district of Cloppenburg , which is southwest of the triangle. In the east is the municipality of Visbek in the district of Vechta . The motorway triangle is not far from the border point between the three districts. It is located about 50 km southwest of Bremen , about 70 km north of Osnabrück and about 35 km south of Oldenburg .

The triangle is also not far from the Wildeshauser Geest Nature Park .

The motorway triangle is at route kilometer 158.3 of the A1 and bears the number 62. On the A29, the kilometering begins at the triangle Ahlhorner Heide, but since the numbering of the junctions is opposite, it bears the number 21.

history

The Ahlhorner Heide triangle was created in 1984 with the opening of the A 29 and its connection to the A 1, which was opened in this area as the A 11 in 1966 . The junction on the A1 was partially dismantled so that there is only a connection with the northern part of the motorway in and from Hamburg / Bremen. The connections between Oldenburg and Dortmund can only be reached via the junction "Cloppenburg" (63), located approx. 4.5 km to the south.

Design and state of development

The A 29 has four lanes in the area of ​​the Ahlhorner Heide triangle. The A1 is currently two lanes in the direction of Bremen and three in the direction of Osnabrück. All ramps are single lane.

In the "trumpet-shaped" triangle, the A 1 forms the continuous relation. Accordingly, the connecting ramps for the A 29 are direct, semi-direct and indirect, with only one central bridge structure. To the north, only a few hundred meters away on the A1 is the junction "Ahlhorner Heide" on the L 870 between Ahlhorn and the B 69 to Vechta , which is also number 62 and forms a double junction with the motorway triangle.

Traffic volume

The triangle is used by around 67,000 vehicles every day.
