The opening of Øresund Landanlæg, including the motorway on 27 September 1997 and the railway on 27 September 1998, marked a leap in mobility at international, national, regional and local levels.

Internationally, the facility across Amager comprises the Danish landworks to Øresund Bridge between Copenhagen and Malmö, which connects the Scandinavian peninsula and the European continent with the railway and motorway. The rapid link to the centre of Copenhagen has also been crucial for Copenhagen Airport's ability to attract more international air routes.

Øresund Landanlæg is in focus from many sides as an important part of the trans-European railway network, which is a prerequisite for a common market with free movement. The realisation of the project was therefore given financial support from the EU.

The Øresund Bridge between Copenhagen and Malmö, and thus the Danish landworks, is the prerequisite for closer contact between the Copenhagen area and southern Sweden, and the formation of a larger, common labour and housing market, which is the basis for the political vision of the Øresund region.

The new link to the other parts of the motorway and railway network also meant easy access to the airport from the rest of Denmark around the Copenhagen city centre. Momentum grew along with Airport's market grew, not least because of a new customer segment from southern Sweden, which had gained easy access to the airport via the Øresund Bridge.

Locally, the motorway and railway gave the traffic pattern on Amager a much-needed boost. Business and the public in Tårnby, Kastrup and in part in Dragør gained an upgraded infrastructure with a rail connection and easy access to the motorway network. A further positive effect was markedly less through traffic on local roads.
