The investment is the design and construction of a GP road between the islands of Wolin and Uznam in \u015awinouj\u015bcie, on the section from Karsiborska street on the island of Usedom to the intersection Du\u0144ska and Fi\u0144ska street one on the island of Wolin, with a total length of approx. 3.2 km. The scope of the investment includes the construction of a tunnel bored using the TBM machine technology under the \u015awina Strait, approximately 1.44 km long, with access to the tunnel in the form of an open trench and a tunnel made using the roof method on the Uznam island and on the Wolin island. The road system will also include: access roads to the tunnel, a maneuvering square, an intersection - a roundabout on the island of Wolin and a T-intersection on the island of Usedom. The investment also includes the reconstruction of the existing adjacent streets.<\/p>\n

Minerals DC Nowak<\/strong> is the main supplier of aggregates for the entire investment, both in terms of concrete mixes and prefabricated elements (CEMEX) as well for the construction of road foundations and stabilization (PORR).<\/p>\n
