The Øresund Link connecting Sweden and Denmark is 8 kilometres (5 miles) of bridge, 4 kilometres of artificially made island, called Pepparholm, and 3.5 kilometres of tunnel. This photo shows the approach to the island.
Reducing travel between Sweden and Denmark to a mere 20 minutes, the link opened in 2000, three months ahead of schedule despite such unexpected hazards as the discovery of 16 unexploded World War II bombs on the seafloor.
This combined road/rail bridge with a four-lane highway on the upper deck and a two-track railway on the lower deck, ferries 60,000 people daily between the two countries – at a toll of €43 ($56 US) for a standard car; a motorcycle is €23 ($30 US) but the train is a mere €9 ($12 US).
In Denmark (left side in photo below), the link begins with a 2.2-mile underwater tunnel. The tunnel emerges from the water onto a roadway on a 2.5-mile artificial island, Pepparholm, which appears as a bright white shape to the south of the natural island of Saltholm. The cable-supported Oresund Bridge stretches 4.9 miles across the eastern part of the Strait toward Sweden, making a thin white line across the image.
Pepparholm? Saltholm? Yes, some humour was applied in the naming of the artificial island 😉
