Expressway S6 (Poland)

Expressway S6 (in Polish "droga ekspresowa S6") is a major road in Poland which has been planned to run from the A6 autostrada in Szczecin, through Goleniów in West Pomerania to Gdańsk parallel to the Baltic coast, forming the main connection between Gdańsk and Szczecin. 
The first section of S6 built was the "Obwodnica Trójmiejska" (Tricity Bypass) from Gdańsk to Gdynia, which is long, followed by the section between Szczecin and Goleniów, both in the 1970s. The next part of S6 to be opened was bypass of Słupsk that was completed in October 2010. The bypass of Nowogard was completed in December 2011, with the rest of the section between Szczecin and Koszalin open by 2019.
In July 2010, the route between Goleniów and Słupsk was finalized - it will be about long and pass just south of Kołobrzeg and then north of Koszalin. The road will be a dual carriageway, with 27 interchanges and 130 viaducts, with about 20% of it overlapping the current route of National Road 6 (DK6). Due to doubts about financing, construction was not expected to start before 2020. However, later, the schedule was accelerated. The tenders for design-build contracts on the section between Goleniów and Koszalin were announced in August 2014, with expected completion around 2018. The exact route of S6 between Słupsk and Gdańsk has not yet been determined. 
After World War I the German "HaFraBa" association had already set up plans to build an "Autobahn" along the route from Berlin, through the Polish Corridor, to the Free City of Danzig and East Prussia (today informally known as Berlinka). The construction was pushed by the Nazi authorities after 1933 as an extraterritorial "Reichsautobahn" across the Polish Corridor of pre-World War II Poland further south than the modern S6 freeway has been planned for, however the road was never completed.
