Bridges

The Øresund has made it easier than ever before to travel between countries that are separated by water. This unique passageway connects the cities of Copenhagen, Denmark with Malmö, Sweden, doing so in two ways: a cable-stayed bridge runs five miles to an artificial island, where it then transitions into a tunnel that extends an additional two and a half miles. A motorway occupies the upper level while the railway line runs below.
