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.
