NEVER SEEN BEFORE VIEW AS METRO DIGS DEEPER

Sydney Metro construction work deep under the city has revealed a view of Sydney never seen before.
 
Workers have finished digging a 19 metre long escalator tunnel to create one of the entrances to the new Martin Place metro station.
 
Minister for Transport Andrew Constance said the milestone has exposed a view of Sydney Tower and the MLC Centre – from 19 metres deep under Martin Place.
 
“We’re getting on with the job of delivering Sydney Metro through the city as quickly as possible. This completed entrance tunnel is a visible reminder that a new generation of fast, safe and reliable driverless metro trains are on their way to more of Sydney,” Mr Constance said.
 
It took about seven weeks to excavate the 19 metre deep 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 is now being waterproofed and lined with concrete.
