The 16.8-kilometre section of the expressway between Koszalin and Zegrze Pomorskie will connect the S-11 route running from Upper Silesia with the S6, i.e. the road from Szczecin to the Tri-City. As part of the contract, Budimex constructed a dual carriageway road with a reserve of space for the third lane, engineering structures (viaducts, bridges and flyovers), access roads for local traffic, service areas, drainage systems. Public roads, electricity and water supply networks were also rebuilt. Infrastructure for environmental protection was also created, including animal crossings. The section was made in the “design and build” system. The S-11 section completed by Budimex starts from the north at the Koszalin Zachód junction and ends in the south at the Zegrze Pomorskie junction and is part of a 40-kilometre expressway running from Koszalin to Bobolice. The investment was completed within 27 months from the start of the works.

The S-11 expressway is one of the most important investments in Poland. The 550-kilometre route running through the Silesian, Opole, Greater Poland and Łódź Voivodeships will not only shorten but also improve the safety of travelling to the Tri-City and Szczecin as well as holiday resorts on the central Baltic coast. The S-11 is also an important investment from the point of view of the economy – connecting the Upper Silesian Industrial Region with the ports of the Upper Silesian Industrial Region. West Pomeranian Voivodeship will have a positive impact on the economic activation of this part of the country.
