Design and construction of the Øresund tunnel Available to Purchase

This paper describes the design and construction of the tunnel section of the new 16 km road and rail link between Denmark and Sweden which opened to traffic in July 2000.The tunnel, which carries a dual carriageway road and a twin-track high-speed railway, is one of the world's largest immersed tunnels with a portal-to-portal length of 4·1 km.The size of the tunnel enabled some innovative, design-led construction methods to be adopted including provision of a purpose-built, production-line casting facility and use of bridge-jacking techniques to move the 55 000 t tunnel elements.The works also incorporate substantial water-excluding approach structures located on an artificial peninsula and island created from material dredged from the tunnel trench.
