The first mega Tunnel Boring Machine on the Sydney Metro City and South West project has arrived at the site of the new Waterloo Metro Station.
The machine had started digging from Marrickville in October 2018.
Minister for Transport Andrew Constance said Tunnel Boring Machine Nancy's breakthrough at Waterloo was an exciting milestone for the country's biggest public transport project.
“When Metro City and South West is complete in 2024 Sydney will have 31 metro stations along a new 66 kilometre metro rail line with the capacity to move about 40,000 customers an hour,” Mr Constance said.
The tunnel boring machine will continue tunnelling towards Barangaroo via new metro stations at Central, Pitt St and Martin Place.
