In this series of short videos, some of the Aurecon engineers who were instrumental in the success of Sydney’s first Harbour tunnel share their stories of technical triumph on a project the likes of which Sydney had never seen.

Our immersed tube tunnelling leader CK Tsang explains why this solution is favoured for harbour environments due to its shallow depth below the seabed, that allows shorter tunnel lengths and better connections to the road network.

Our tunnelling team, those who worked on the Sydney Harbour Tunnel and those who are aiming to be part of the vibrant city’s future history, want to take the brilliance of an engineering solution used only once in Australia’s history to shape the next generation of passenger outcomes.

Their aim is to design a solution that will allow commuters to travel to exactly where they want to be – quicker, easier and smarter – adding another layer to Sydney’s transport network to allow people to connect better.
