Breakthrough milestone at Sydney Metro West

Sydney Metro Breakthrough

Two tunnel boring machines (TBMs) have broken through to arrive at Five Dock Metro Station, as part of the Sydney Metro West project in New South Wales (NSW).

TBMs Daphne and Beatrice achieved the first two breakthroughs for the project, as work continues to build twin 24km metro tunnels between Westmead and Sydney.

Daphne broke through first before Beatrice, after building the 4.3km section of metro tunnel from The Bays to Five Dock for seven months.

The two machines will spend the next few weeks travelling to the western end of the station cavern, where they will undergo maintenance before relaunching to continue their journeys to Sydney Olympic Park.

To date, the TBMS have excavated a total of 437,463 tonnes of material each and installed around 30,732 concrete segments to line the new tunnel walls.

The next stop for the TBMs is the Burnwood North Metro Station, where they are due to arrive in early 2024.
