Oresund immersed tube tunnel

When the £1.95bn* 0resund Fixed Link between Denmark and Sweden is finally opened next year it will be the culmination of more than 10 years of planning, design and construction. Its economic and social impact on the regions at each end of the crossing will be profound. Inevitably, it will be the cable stayed bridge and approach viaducts which make up the eastern section of the Link that will attract most attention. But already structurally complete and being fitted out is the other, less visible western section of the Link, the world's largest immersed tube tunnel.

Many complex environmental, ecological and political factors shaped the design of the 16km crossing. One in particular, the need to avoid any serious restriction to the flow of oxygenated, saline water in and out of the Baltic was to have a major effect on the project. Coupled with the proximity of flight paths into Copenhagen, this imperative led to the choice of an immersed tube tunnel for the first 4km of the link.

The multi-national joint venture that won the £350M* contract for the tunnel did so because it combined established technologies to produce elegant, innovative solutions to the many technical and logistical problems it faced.

It is the achievements of the 0resund Tunnel Contractors jv, and in particular the contribution of its UK participants that are celebrated in this NCE project study.
