The A-B Landbridge Project is financed under the INTERREG IIIB CADSES Programme. Its primary objective is to promote territorial cohesion between the Adriatic-Baltic short sea shipping areas, while fostering balanced, environmentally sustainable accessibility to new global markets. These long-term objectives are based upon the full deployment of the A-B landbridge corridors, and the logistics elements for ensuring the viability of the intermodal connections. The project analyses 3 A-B Landbridge corridor itineraries in terms of current (2006) and expected (2010, 2020) modal supply and demand, logistics considerations and spatial planning scenarios with the aim to establish new, real multi-sectoral partnerships between actors from different administrations, institutions and the private sector. Furthermore, a variety of institutional setting activities focuses on developing sectoral forum discussions (such as the spatial development forum and the high-level transport advisory board) to broaden the institutional reference base. The Project fosters the regional economic cohesion between Western and Eastern CADSES countries, through investment in sustainable transport modes, especially sea and rail. The CEI intergovernmental structure (Working Groups on Transport, Environment), as well as CEI networks such as the Science and Technology Network, the CEI business network, the North Adriatic Port Area Network (Trieste, Koper and Rijeka) ensures the participation in the project of different key players (Governments, Development Agencies, international bodies such as UNECE Trans European Railways, port authorities and related SMEs), in order to promote project results as the basis for future development strategies.
