Øresund Bridge

A combined motorway and railway bridge that connects Sweden and Denmark. The bridge starts in Sweden and then it morphs into a tunnel through an artificial island. The reason for this design is to not negatively effect the natural flow of water from the Atlantic ocean into the Baltic sea.
