Copenhagen’s New Artificial Island Hits Rough Seas

Swedish officials have joined Danish critics in registering concerns that an island-building plan — a signature test of Copenhagen’s development model — could have environmental risks.

This March, the Danish Parliament starts deliberating on a massive engineering project: the construction of a new artificial island called Lynetteholm. If approved, a 1.1 square mile (2.8 square kilometer) land mass will emerge from the harbor waters just north of Copenhagen’s city center; by 2050, it could be built-up with enough homes to house 35,000 people.

Lynetteholm is supposed to not only ease the Danish capital’s chronic housing crunch but also act as a springboard for an ambitious rethink of the city’s infrastructure. Revenue from the housing development would fund a new tunnel under the harbor, through which a subway line would be routed, as well as a section of beltway providing swifter journey times from the airport to the wealthy suburbs that form Copenhagen’s so-called Whisky Belt. The project, conducted by a public-private corporation called By og Havn (City and Harbor) that is co-owned by the city of Copenhagen and the national Ministry of Transport, would reshape both Copenhagen’s coastline on the narrow Øresund Sound and its transit network.
