Sydney Metro West Cavern Completed at Hunter Street Site

Sydney Metro West has reached a key milestone with the completion of excavation works at Hunter Street Station, the final stop on the 24-kilometer line between Parramatta and the Sydney CBD. This is reported by the railway transport news portal Railway Supply.

For 20 months, crews worked nonstop to carve out the enormous cavern, measuring 180 meters long, 28 meters wide, and 20 meters high, beneath central Sydney.

Sydney Metro West excavation completes at complex city site

To construct the cavern, 57 workers and a single roadheader removed over 240,000 tonnes of material with high precision and strict safety standards.

Because the site lies only 1.8 meters from the M1 Metro Line and under the State Library of New South Wales, excavation demanded sub-millimetre accuracy.

The finished station will feature entrances at George and Hunter streets and at O’Connell and Bligh streets, improving pedestrian access to central Sydney.

Sydney Metro West expected to boost future city rail demand

When operational in 2032, the station is set to become the busiest on the Sydney Metro West route, easing congestion and reducing travel times.

Construction teams used advanced monitoring systems to manage structural risks while working beneath sensitive heritage zones and active infrastructure.

The completion of the Hunter Street cavern signals broader progress across the Sydney Metro West project, which will double rail capacity between Sydney’s key economic hubs.

As Sydney prepares for future population growth, this metro expansion continues to represent one of the city’s most transformative transport investments.
