The project
The tunnel is part of a 16km long high speed rail and
road link between Denmark and Sweden that crosses the
Øresund. The tunnel carries a twin-track railway and a dual
carriageway road under one of the Øresund’s two navigation channels
and has an enclosed length of 4 km.
It comprises:
- An artificial peninsula on the Danish coast incorporating a
ramp structure, portal, cut and cover tunnel and a service
building.
- A 3.5km long immersed tunnel made up of twenty concrete
elements
- An artificial island located between the two navigation
channels, providing a transition to the adjacent high level bridge
section of the link. The island incorporates a ramp
structure, portal, cut and cover tunnel and service building.
For the substantial portal structures, three principal forms of
water-excluding construction were used:
- Cut-and-cover tunnels
- Gravity U-box structures
- Anchored U-box structures - approximately 2300 ground anchors
were installed.
Mechanical and electrical systems within the tunnel include
longitudinal ventilation, pumped drainage, fire fighting, lighting
and control and communications.
