The fixed link across the Fehmarnbelt between Denmark and Germany is one of the world's system-changing mega projects. The change to infastructure and accessibility generated by the link has the potential for creating a new economic, cultural and social development in the regions and countries surrounding the link. The future benefits are considerable. This is the conclusion from a new scientific study of the regional effects of the fixed link. New infrastructure of this magnitude has always caused major change, the book states. New relationships will arise and create the basis for new trade, tourism, jobs and lifestyle choice. This is bound to have a profound impact on the communities surrounding the link - both with regard to the neighbouring areas of Southern Zealand, Lolland, Falster and East Holstein and further afield, (ie: between Copenhagen, Malmö and Lund (the Øresund City) and Hamburg). The major Northern German cities of Kiel, Lübeck and Rostock are also set to gain from the new regional development perspectives.
