Chatswood and Marrickville Dive Sites

The Chatswood Dive structure once completed will be 25 metres deep, 250 metres long and 32 metres wide, with around 143,000 tonnes of crushed rock being excavated. That’s enough to fill 22 Olympic-sized swimming pools!! The Marrickville Dive site was established to manufacture pre-cast concrete tunnel lining segments. Both sites and tunnel portals were built to support the launching of the Tunnel Boring Machines (TBMs) and all other tunnelling operations.
