As yet, there has been no final decision on consent for a major proposal to construct a man-made island across the main entrance to the harbour although they have got as far as calling the island Lynetteholm.

With extensive new areas of housing - comparable in some ways to the work at Nordhavn - it would be immediately beyond Trekroner / The Triangular Fort and would be constructed across a deep and well-established navigation channel that is the entrance to the harbour from the sound.

If the island is constructed there would be just narrow passageways from the harbour to the open sea between the new island and Refshaleøen and between the island and Nordhavn and it would certainly block the view out from the harbour to the open water of the sound and certainly change the character of the harbour.

Dan Hasløv, in a recent article, published on line on the site of Magasinet KBH, has proposed an alternative site further south and further out in Middelgrunden - an area of shallower water - and there would be a wide channel between Refshaleøen and the new island.

One important role for the new island is to protect the inner harbour from storm surges but this would still be possible with barriers across to the fort from each side.

The current proposal includes road tunnels and metro tunnels to link the new island to Nordhavn and to Amager with the possibility of extending the metro under the sound to Malmö and again all that would still be feasible if the new man-made island is further round to the south but could also reduce the impact of a major new road down the east side of Amager that is part of the current proposal that would link Nordhavn to the Øresund bridge.
