The project will create comprehensive assessment of FinEst Transport Link and a plan for the future fixed link between Helsinki and Tallinn. The vision of the fixed link is already a reality. It has been discussed by experts, politicians and the general public for 20 years. The pre-feasibility study in TalsinkiFIX Seed Money project presented a result that the vision might be also technically and economically possible. All actors involved in Helsinki-Tallinn transports already have to take this vision into account when planning new investments. The project focuses in wider Finnish-Estonian perspective, European TEN-T perspective, transport technology development, environmental aspects and in changing socio-economic context of the emerging twin-city region. Assessment and development of the fixed link option and its’ impacts pave the way for deeper integration of regional economies, twin-city and regional co-operation, and for achieving better integration in the multimodal cross-border transport systems with significant impact on lowering the CO2 emissions. The project will look and explore the required development needs of traffic between Helsinki and Tallinn in the long run. As a main result it will create preconditions and strategy for 80% saving on travel time of passengers and cargo in Helsinki-Tallinn link. The project will complement and support actions in other related projects by outlining, analyzing and assessing the fixed link. It will also assess alternative ways of developing transport operations and physical infrastructures in the era of digitalization of mobility. The partnership is based on trilateral cross-border cooperation: cities responsible of actual transport nodes, regions responsible of regional spatial planning, including transport networks, and the state authorities responsible of national transport policy development and representing national interests towards TEN-T policies.
