TBM emerges in Sydney

After approximately six months of tunnelling under Sydney Harbour for the Sydney Metro project, a tunnel boring machine (TBM) has emerged at Blues Point.

John Holland shared a picture of TBM Kathleen on social media after it tunnelled 885 m from Barangaroo to Blues Point at depths as low as 40 m.

“This is what the might of Sydney Harbour did to our once crispy clean TBM,” said the company.

TBM Kathleen is named after Kathleen Butler, who was the technical advisor to engineer John JJC Bradfield on the construction of Sydney Harbour.

Along with four other TBMs, Kathleen will deliver twin 15.5 km rail tunnels for the Sydney Metro project.
