As part of a larger project group organised by Sund & Belt, SLA has carried out preparatory studies for a harbour tunnel in Copenhagen Harbour.

The primary purpose of the tunnel will be to take heavy traffic from the city centre and thus calm the inner city.

The preparatory studies resulted in four architectural and urban design solutions that connect the tunnel with Copenhagen city centre.

SLA has prioritised the supplementation of the solutions with initiatives which create new, untraditional green urban spaces in Copenhagen harbour.

The extra land model consists of a closed vehicular ramp to the tunnel in connection with the existing quay.

As can be seen from the illustration, this development further enhances the city environment with an extended public harbour park.

The spiral design is a closed traffic development that creates a luxuriant public park in the harbour development. This new urban space is planted with exotic plants and combined with an open-air pool thus creating a different and island-like oasis in the centre of the harbour

The four models are all placed with Langebro (bridge) as an example. The circle design is shown here, which consists of a circular road with two ramps to the tunnel. The bridge itself is retained, but the traffic over it is re-routed. This solution creates the conditions for a new, exciting urban space on the bridge for cyclists and pedestrians.

The addition design extends the bridge with long access and exit ramps to the tunnel. The ramps are placed under new buildings with residential and cultural functions, making the harbour an untraditional and attractive walkway.
