Sydney Metro marks milestone with TBMs in Parramatta

The Sydney Metro has reached a major construction milestone with tunnel boring machines arriving in Parramatta as 90% of the tunnelling work nears completion on the 24-kilometre underground route. This is reported by the railway transport news portal Railway Supply.

Sydney Metro construction advances in western corridor

TBM Dorothy has broken through solid rock to reach the Parramatta station site, while TBM Betty has progressed over 175 meters toward Westmead since leaving on July 17.

Crews have operated both machines tirelessly for 17 months, working five days a week to construct tunnels between Sydney Olympic Park and Parramatta.

Together, the machines have excavated around 1.25 million tonnes of earth.

They also installed over 48,000 concrete segments, each weighing up to four tonnes, to line the seven-kilometre tunnels.

This effort marks one of Australia’s most complex metro construction operations to date.

The two TBMs will complete the western end of the Sydney Metro line by the end of 2025.

Six of nine planned station boxes—including Westmead, Burwood North, and The Bays—are already excavated and reinforced.

Ongoing excavation continues at Hunter Street, Pyrmont, and Parramatta.

Sydney Metro transforms Parramatta’s urban future

The Parramatta metro station will anchor a vibrant mixed-use development covering 24,150 square meters across two city blocks.

The precinct will deliver about 100 new residential units, commercial offices, and multiple retail and entertainment spaces.

So, the location will offer direct access to Light Rail services and the Civic Link, a 450-metre pedestrian corridor leading to Powerhouse Parramatta.

And it will sit within walking distance of Eat Street, creating a connected cultural and transit hub.

The Sydney Metro West project not only improves travel between Greater Parramatta and the CBD but also reshapes the city’s infrastructure and urban landscape.

Because of its scope and scale, this project positions Sydney as a global model in sustainable urban mobility.

As tunnelling nears completion, the focus now shifts to station development and future service integration.

Authorities and engineers emphasize safety, efficiency, and livability as core outcomes for the next construction phase.
