the if or when and the how much and why of new islands and tunnels under the sea
/This week, politicians in Copenhagen have to agree a budget for the city for the next financial period and the main item on their agenda will, presumably, be discussions about moving to the next stage their ambitious plans to construct a large new island across the entrance to the harbour …. a major engineering project that has been agreed in principle by both the national government and by the city and agreed across most political parties.
Initial plans set the new island immediately beyond and close to the Trekroner Fort - built in the late 18th century to guard the entrance to the harbour - but the most recent drawings published show that it will now be further out into the Sound and will cover a larger area of about 3 square kilometres. There will be a large park along the eastern edge - planned to be larger than the well used and popular Fælledparken on the north side of the city - with homes on the island for 35,000 people and work there for at least 12,000 people although some assessments have suggested that as many as 20,000 new jobs will be created.
But the new island is not simply the next version of Nordhavn - just larger and further out - but it is also an integral part of an expansion of traffic infrastructure on this side of the city and there will be extensive flood defences on the east or outer side of the island that faces out across the open Sound …. defences that will be an important part of the protection against storm surges that could flood the inner harbour as the climate changes and as sea levels rise.
The name for the new island - Lynetteholm - was, In part, inspired by the shape with a broad curve to the east side - the side facing out across the Sound - and is from the Danish version of the French word lunette and that has been combined with the Norse word holm for a low island that was usually in a river or estuary and was often meadow.
However, Lynette is not a new name in this area of the outer harbour because it was the name of a curved outer fortress built in the Sound in the 1760s that, with large guns set up there, was an important part of outer defences that protected the entrance to the harbour.
