On 23 March 1991, the governments of Sweden and Denmark signed an agreement for a fixed link over the Øresund straight in order to improve traffic communications between the two countries. This project also connected the Nordic Triangle road and rail links (PP12) via Denmark and the Fehmarn belt (PP20) with Germany and Central Europe.
The Øresund fixed link is a Priority Project completed without budget overruns or environmental problems. It has contributed to a great increase of the traffic and it has a very important positive impact on the development of the regions of Copenhagen and Scania. It also contributes to the better connection of the Nordic countries to Central Europe.
