X-Plane 10 – Scenery Great Belt Fixed Link Denmark. The Great Belt Fixed Link runs between the Danish islands of Zealand and Funen. It consists of three structures: a road suspension bridge and a railway tunnel between Zealand and the small island Sprogo located in the middle of the Great Belt, and a box girder bridge for both road and rail traffic between Sprogo and Funen. The link replaced the ferry service that had been the primary means of crossing the Great Belt. By Erik Rasmussen.
