 The Port of Odense consists of three main basins and a number of facilities along the canal , with quays measuring roughly 4 @,@ 200 metres ( 13 @,@ 800 ft ) in length in total . Vessels up to a length of 160 metres ( 520 ft ) and a draft of 6 @.@ 8 metres ( 22 ft ) are facilitated in the port . The wharf for tankers is situated outside the harbour on the southern side of the canal , with facilities for tankers , general cargo ships , bulk , and LPG ships , and has a depth of 7 @.@ 5 metres ( 25 ft ) . Accessibility to Odense was greatly increased when the ferry service between the two main Danish islands , Zealand and Funen , was replaced by the Great Belt Bridge – opened in 1997 for rail traffic , 1998 for road traffic . When the bridge opened , it was the second longest suspension bridge in the world . Aarhus can be reached by train in 1 hour and 33 minutes while , thanks to the Great Belt Bridge , trains to Copenhagen can take as little as an hour and a quarter .
