Denmark and Germany signed up last week for the construction of a $8.1 billion (€5.6 billion) road and rail bridge by 2018. This 19 kilometres (12 mi) long  bridge will connect the German island of Fehmarn with the Danish island of Lolland across the Fehmarn Strait in the western Baltic Sea . The bridge should replace the ferry services and air traffic between the two countries. Sea traffic will be possible underneath the bridge as the vertical clearance will be of 65 m (213 ft). It will be a cable-stayed bridge with three 724 metres (2,375 ft) long spans, and four pillars about 280 metres (919 ft) tall. It will allow four road lanes and two rail tracks.
