Whether navigating the existing built environment or chartering through new regional territory, tunnels are a solution that maximise available space and enhance community liveability.

Man in a tunnel

Tunnel solutions are becoming more popular as built environments challenge us to find new solutions to maximise space and create community benefit  in our infrastructure.


WSP has one of the largest and longest-standing tunneling practices globally. Our expertise spans the entire project lifcycle from feasibility to design, construction management, testing and commissioning, and operation and maintenance.


We combine new technology with our years of experience to design transport tunnels and underground spaces in a variety of complex ground conditions including basalt, clay, sandstone and siltstone.


For more than a decade, we have had a significant  role in delivering city-shaping tunnel projects such as the Lane Cove Tunnel in Sydney, Airport Link in Brisbane, Waterview Connection in Auckland, Forrestfield-Airport Link,  and the new Melbourne Metro Tunnel and Sydney Metro.

Locally Dedicated with International Scale

Our global presence means you can draw on our experience across various ground conditions in big cities, seismic areas, mountains, and underwater.



Our design teams work extensively with the latest technologies, including digital modeling of ground/structure interaction, BIM and VDC.
