description Øresund Tunnel Overview
The Øresund Tunnel carries road and railway traffic from the Copenhagen side of the Øresund crossing to the artificial island of Peberholm. Also known as the Drogden Tunnel, it forms the western underwater section of the fixed link between Denmark and Malmö in Sweden. Construction was completed in 1999, and the connection opened to traffic in 2000. A four-lane motorway and a twin-track railway occupy separate passages within the structure.
Instead of being bored through the ground, the tunnel was assembled from large prefabricated concrete elements lowered into a dredged seabed trench. At Peberholm, the route changes from tunnel to bridge. This combination makes it useful for understanding how a cross-border transport link can employ different structures along one route, while carrying both private vehicles and scheduled rail services.
help Øresund Tunnel FAQ
What two Scandinavian countries does the Øresund Tunnel connect?
The Øresund Tunnel connects Copenhagen, Denmark, to Malmö, Sweden. It is the westernmost underwater segment of the larger Øresund Bridge and tunnel link. It emerges onto the artificial island of Peberholm before the bridge section begins.
What type of engineering structure is the Øresund Tunnel?
Rather than being bored through rock, it is an immersed tube tunnel built using pre-fabricated concrete segments. These segments were sunk into a dredged trench on the seabed of the Øresund strait. This method was chosen due to the relatively shallow depth of the water.
Can both trains and cars travel through the Øresund Tunnel?
Yes, the immersed tube accommodates both a dual-track railway and a four-lane motorway. The rail and road traffic are housed in separate, parallel chambers within the concrete tunnel structure. This allows seamless road and rail transport between the two countries.
When was the Øresund Tunnel completed?
The immersed tunnel was completed in 1999 and officially opened to traffic in 2000. It was a crucial part of the massive Øresund Bridge project. The entire link has drastically improved travel and commerce in the Øresund region.
