To build the West Gate Tunnel, approximately 1.5 million cubic meters of rock and soil will need to be removed. Digging up this amount of soil to build the West Gate Tunnels will be a 24/7 operation at our tunnelling hub in Yarraville.

The West Gate Tunnel Project is being built in former industrial areas, testing has found low levels of the group of chemicals known as PFAS (Per- and polyfluoroalkyl substances) will be found in some of the excavated soil during tunnelling. To ensure it is managed safely for workers and the community, EPA Victoria and WorkSafe Victoria requirements will be met at every step of the way.
