As this fragment of highway was constructed during the Cold War, the military function of mighty strip of solid ground was not forgotten.
One of the structures were rows of pillars that were supposed to carry a viaduct over then-proposed northern branch of Central Railway Line towards Gdańsk (which was never constructed).
Traces of earthworks and forestry work were visible on satellite imagery and aerial pictures to Stryków.
In January 2010, as part of preparation to construction of motorway A2, deforestation was started, with additional works related to dismantling of then-existing viaducts.
It made possible to drive on former Olimpijka – 36 years after beginning of the first construction – from Warsaw through Poznań to Berlin and further without leaving the motorway.
