The Nordic Triangle links the Nordic countries of Sweden and Finland and their capitals to each other and improves passenger and freight transport from the region to central Europe, the Baltic countries, and Russia. The multimodal scheme involves the upgrading road, rail and maritime infrastructures in both countries.


The Nordic Triangle in Sweden extends to include Øresund fixed link (PP11).
