Immersed tunnels have a number of benefits that make them an attractive option in realising links and connections, particularly across waterways and rivers, but also for the crossing of sea straits and special assets (buildings, runways). Shorter crossings benefit from their position immediately under the sea bed and they are perfect for wider tunnels with multi-modal traffic.
We have been and continue to be a part of some of the most complex and ambitious immersed tunnel projects in the world. From the the Hong Kong Zhuhai Macao Bridge Project, to tunnels beneath runways of Schiphol Airport, our work pushes the boundaries of what is possible to realise ambitious links between cities and nations.
Our expertise on immersed tunnels
Some of the first immersed tunnels were developed in the Netherlands, as an ideal solution to crossing the many rivers across the country. We have built on that heritage and today our immersed tunnels represent the majority of immersed tunnels across the country – while taking our expertise to increasingly complex projects around the world and have become a world leading design and engineering consultant in this field.
