Tunnelling for Sydney Metro West is nearly 90% complete, after the arrival of two TBMs at Parramatta’s metro station site.
TBM Dorothy arrived at Parramatta last week after breaking through a solid rock wall, while TBM Betty is already 175m into its final stretch of tunnel to Westmead after departing Parramatta on July 17.
Since their launch 17 months ago to build the 7km tunnels between Sydney Olympic Park and Parramatta, the two TBMs have excavated approximately 1.25 million tonnes of earth and installed more than 48,000 precast concrete segments, each weighing up to four tonnes.
A community open day on August 9 at the future Parramatta metro station will allow the public to see TBM Dorothy in the station box.
Both TBMs will complete the main line tunnels at the western end of the line by the end of the year.
TBMs Jessie and Ruby recently made a double breakthrough at the Pyrmont metro station cavern.
Six of the nine station boxes for the Sydney Metro West project have been excavated and lined; including at The Bays, Five Dock, Burwood North, North Strathfield Sydney Olympic Park and Westmead. Work continues at Parramatta, Pyrmont and the Hunter Street station in the Sydney CBD.
Parramatta metro station will anchor a mixed-use development of four buildings spanning 24,150m2 over the equivalent of two city blocks, providing about 100 new homes, office and retail spaces, dining and entertainment.
The new transit hub will be a short stroll to nearby Eat Street, adjacent to light rail services and connect directly to the new Civic Link, a 450m-long pedestrian spine linking the metro precinct to the future Powerhouse Parramatta.
Sydney Metro West project is a new 24km underground metro railway which will double rail capacity between Parramatta and the Sydney CBD. It has a target opening date of 2032.
