S6 Expressway Finally Complete: Szczecin to Gdańsk in 3.5 Hours
Poland officially opened the final section of the S6 expressway on June 24, completing the Baltic coast route from the German border to Gdańsk. The 40-kilometer missing link between Leśnice and Słupsk now allows drivers to travel the entire route in about 3.5 hours.
The final section of the S6 expressway connecting Western Pomerania with the Tri-City area is complete. On Thursday, June 24, 2026, the section between Leśnice and Słupsk was officially opened. Travel from Szczecin to Gdańsk will now be comfortable and quick.
Prime Minister Donald Tusk and Infrastructure Minister Dariusz Klimczak participated in the opening ceremony. The completion represents the culmination of construction work spanning 2010-2026 on one of Poland's most strategically important highways.
A Strategic Baltic Coast Link
The S6 expressway (officially known since 2025 as "Trasa Kaszubska" or Kashubian Route) is part of the international Via Hanseatica route connecting cities of the southern Baltic, from Lübeck in Germany to Riga in Latvia. Within Poland's borders, the S6 runs 480 km from Kołbaskowo (German border) to Grzechotki (border with Kaliningrad Oblast).
After opening the road, the route from Tri-City to Szczecin can be covered in approximately 3.5 hours. The new expressway eliminates the previous bottleneck that forced summer holiday traffic through Lębork and other coastal towns, dramatically improving access to popular Baltic resorts like Łeba, Ustka, and Darłowo.
The road features modern dual carriageways with no at-grade intersections, numerous engineering structures including interchanges, overpasses, viaducts, and wildlife crossings. Interestingly, two sections of the expressway use concrete surfacing rather than the more typical asphalt.
For foreigners in Poland: The completed S6 is a game-changer for anyone traveling to Poland's Baltic coast or between Gdańsk and Szczecin. Summer travel to beach destinations will be significantly faster and more comfortable. The expressway also improves Poland's connection to Germany—Berlin is now less than 5 hours from Gdynia. If you're driving, note that this is a toll-free expressway, and the modern route includes well-marked service areas. The completion demonstrates Poland's ongoing investment in transport infrastructure, funded through EU operational programs and the national budget.
