Sydney Metro workers have completed digging a 19m long escalator tunnel for the new Martin Place metro station, revealing a first glimpse at a new view of Sydney.
The milestone has exposed a never-before-seen view of Sydney Tower and the MLC Centre – from 19mdeep under Martin Place.
It took about seven weeks to excavate the tunnel, which will house four escalators as customers travel to the new underground metro station.
The tunnel was built under the historic 50 Martin Place building, navigating the basement of the heritage-listed structure.
More than 2,000 tonnes of crushed rock was removed and 700 tonnes of shotcrete used to line the tunnel.
The tunnel will now be waterproofed and lined with concrete.
