Sydney Metro West is getting ready to launch a TBM to build Sydney’s second under-harbour rail line. Herrenknecht TBM Jessie will launch from The Bays to begin carving out a 2.3km tunnel to Hunter Street in the CBD as part of the Sydney Metro West – Eastern Tunnelling Package (ETP) being constructed by the John Holland, CPB Contractors (CPB) and Ghella joint venture (JCG JV).
This follows Sydney Metro’s first successful crossing between Blues Point and Barangaroo as part of the City & Southwest project.
TBM Jessie is the fifth TBM to start tunnelling on Metro West, with the sixth and final TBM to launch from The Bays later this year.
The TBMs will cross under Sydney Harbour, alongside the iconic Anzac Bridge, heading to the Pyrmont Station site. The TBMs will then continue under Darling Harbour before reaching the Hunter Street Station site in the heart of the Sydney CBD.
Once launched, the TBMs will tunnel at an average rate of 90m per week and will arrive at the Hunter Street Station site in mid-2025.
This is the first mixed shield (slurry) TBM to be used on Metro West, which is specifically designed to excavate in the highly pressurised conditions that are expected under Sydney Harbour.
By connecting Parramatta to Hunter Street, Sydney Metro West will double rail capacity between the two CBDs, linking new communities to rail services and supporting employment growth and housing supply.
Sydney Metro West will target an opening date of 2032.
