The Dreieck Havelland (German: Autobahndreieck Havelland, abbreviated AD Havelland) is a trumpet interchange in the German state of Brandenburg in the metropolitan region of Berlin.
The interchange connects the A24 coming from Hamburg to the A10, the Berlin-beltway.[1]
The interchange lies in the region of Havelland after which it is named, in the municipal area of Oberkrämer and Kremmen in the Landkreis Oberhavel. The nearby towns are Schönwalde-Glien und Nauen. It lies approximately 30 km northwest of the Berlin city centre.
Dreieck Havelland was built as a trumpet interchange between 1972 and 1979, as they were extending the Berlin-beltway.
In July 2011, the plans were made to widen the road from junction Neuruppin (A24) to junction Oberkrämer (A10) into 2x3 lanes. Together with this plan they reconstructed the interchange.[2] On 17 September 2012 the work not part Dreieck Havelland–Kremmen began.[3]
The official opening of the interchange to traffic was on 18 November 2014.[4]
