peer reviewed ; The aim of the project was to perform a feasibility study for possible development of freight intermodal transport links between Belgium and Bulgaria, between North and Black sea and vice versa, taking inland waterways (iww) transport mode as basic one. The key focus is assessment of benefits in adopting an intermodal manner for transferring cargo instead of the single transport mode currently in use. The paper comprises short description of trans-continental infrastructure between Belgium and Bulgaria and its abilities to serve for different transport alternatives, definitions and choice of appropriate scenarios for realising predicted cargo flows, as well as cost calculations. Comparative analysis of the considered transport alternatives has been made. The most important results obtained are transport cost evaluation and benefit assessment for investigated transport scenarios
