Gallery: Sydney Metro station cavern takes shape

Work on excavating the caverns for Pitt Street Station on the Sydney Metros is taking progressing well with more than 116,000t of material already removed by three roadheader machines working round the clock.

The completed cavern, which is 20m below ground level, will be 240m long and 11.5m wide when completed.

Sydney Metro has made a commitment that the crushed rock excavated by the three roadheaders at Pitt Street and seven others working on the project will be reused.
