Sydney’s metro tunnels nearing completion

Twenty-two kilometres of the Sydney Metro tunnels are now complete, leaving about 30 cent left of the mammoth public transport project.

Tunnel Boring Machine (TBM) Nancy tunnelled its way to the new Martin Place Station last week, where it was welcomed by Premier Gladys Berejiklian, Transport Minister Andrew Constance and workers.

Since launching in October 2018, TBM Nancy has cleared 6.8 kilometres via the new metro stations at Waterloo, Central and Pitt Street.

“While people are getting on with life in the city above, deep underneath the CBD giant machines like TBM Nancy are getting on with the job, building tunnels for our future metro rail,” said Berejiklian.

“This tunnelling is pivotal to a well-connected public transport system here at Martin Place, where customers will be able to transfer between the new metro and the Eastern Suburbs & Illawarra line,” said Constance.

TBM Nancy will spend a few weeks undergoing maintenance before being re-launched to complete the last 1.3 kilometres between Martin Place and Barangaroo.

Before TBM Nancy’s arrival, workers spent 21 months building the caverns for the new Martin Place Station, removing about 198,000 tonnes of rock in the process.

“Deep under city streets and buildings, this historic new metro line will not only increase the capacity of our rail network but make it easier to get around,” said Constance.
