Across from Winsor Reserve on the east side of Greensborough Road, between Yallambie and Watsonia Roads (underneath the big green gantry crane), our tunnel boring machines (TBMs) have officially launched from the 40-metre-deep launch box area.

TBM 'Zelda,' named after local legend and lifelong advocate for gender equality Zelda D'Aprano, started boring in August 2024 and is now carving out the northbound section of the North East Link tunnels from Watsonia to Bulleen.

TBM 'Gillian,' named after Dr Gillian Opie, a pioneering neonatal paediatrician at the Mercy Hospital for Women, began its boring journey in October and is making its way towards Bulleen.

We have also finished building the large shed at the corner of Yallambie and Greensborough roads. This shed stores concrete segments used to form the walls of the 6.5 km tunnels. As each TBM digs its way underground to Bulleen, it places these concrete segments behind it.
