When Sweden and Denmark built a connection between their countries, Sweden preferred a bridge, and Denmark preferred a tunnel, they each built their half and connected them in the middle with an artificial island. The Øresund Bridge is unique in the world.

    The justification for the additional expenditure and complexity related to digging a tunnel for part of the way, rather than raising that section of the bridge, was to avoid interfering with air traffic from the nearby Copenhagen Airport, to provide a clear channel for ships in good weather or bad, and to prevent ice floes from blocking the strait. The bridge received the 2002 IABSE Outstanding Structure Award.
