A new ‘mini’ Tunnel Boring Machine (TBM) has arrived on site, ahead of a major construction blitz.
It will dig a new section of the North Yarra Main Sewer, with 600 metres of the 100-year-old sewer being diverted to make way for the new West Gate Tunnel.
Once launched, the mini TBM will move 12 metres a day and excavate around 9000 cubic metres (3.6 Olympic sized swimming pools) over the next year to build the new section of sewer.
For the next 12 months, Whitehall Street in Yarraville will be closed to northbound traffic between Leek Street and Somerville Road, as sewer diversion works take place.
As part of a works blitz, the West Gate Freeway will also be closed for five consecutive nights from Sunday 15 July, as workers remove overhead gantries and light poles to begin the construction of two new lanes in each direction on the freeway.
