Tunnel boring machine Grace has broken through at Redcliffe Station, having successfully tunnelled 4.6km since starting her underground journey from Forrestfield mid-2017. A crew of 15 guided TBM Grace into the 12m-deep underground station over a period of 24 hours. This is the last time the TBM will ‘surface’ before reaching its final stop at Bayswater Junction.

A major milestone was celebrated recently with all tunnel segments required for the 8km twin-bored tunnels produced. A total of 9098 rings - that's 54,588 segments - have been poured, moulded, steam cured, painted and tested at a purpose-built facility in Forrestfield.
