摘要:International Waterway E60 (IWW E60) is a sea-shore route running from Gibraltar to the North along European coast up to St. Petersburg then through the Baltic-White Sea Channel, then along the White Sea coast to Arkhangelsk. From the German-Polish border, along the Polish, Russian and Lithuanian coast to the Lithuanian-Latvian border, the route is 610 km-long and runs along 32 Polish municipalities and 4 Lithuanian regions. Determining the role of IWW E60 is important in the context of economic growth of municipalities and coastal regions, especially through the development of local seaports. Operations of the multifunctional port have a wide economic and social impact. Mutual interaction of functions can be observed on the example of fisheries, where in the port area fishing functions intermingle with the processing, tourism, storage and distribution function. The main socioeconomic benefits of E60 waterway development include the increase in employment, economic activity, generation of added value and improvement of transport infrastructure. In addition, ports influence attractiveness of the regions and create impulse for new jobs in the tourism industry. Until now there have been no attempts to make E60 route navigable or only on short sections, usually between two neighbouring ports. Despite the significant cross-border importance of this connection, no directions for its optimal development were defined. What is more, the route is not used. In connection with this, steps were taken to thoroughly investigate the problem and determine the possibility of its development as part of inland waterways network.
