The North Sea-Baltic corridor is multimodal and connects the Baltic Sea region with the countries of the North Sea region, improving the accessibility of the northern Member States and the connection between the northwest and the northeast of the European Union. The corridor passes through Belgium, the Netherlands, and northern Germany, Poland and then north through the Baltic States. Since its extension in 2021, the whole of Finland and the northern part of Sweden are part of the corridor and a section in Poland up to the border with Ukraine. As since its extension, the North Sea-Baltic Corridor now consists of 8828 km of railways, 6934 km of roads and 2839 km of inland waterways.
