Work on Sydney Metro Nothwest has reached a major milestone with the final tunnel breakthrough completed at Cherrybrook. 30 kilometres of earth has been dug through to complete the twin tunnels.

The breakthrough completes the longest railway tunnel ever dug in Australia.

“Today everyone can be proud at what’s been achieved, with this long-promised critical public transport project taking shape before our eyes,” Mr Baird said.

“This rail line will transform the lives of people in Sydney’s north-west, enabling commuters to catch a train every four minutes in the peak.”

Workers have collectively spent more than 360,000 hours underground building the tunnels.

“I pay tribute to all the men and women who have worked on this massive project and ensured tunnelling has finished about two months ahead of schedule,” Minister Constance said.

“About 2.7 million tonnes of Sydney Sandstone and shale has been excavated to complete the job.”

“It’s taken just 16 months for our four giant tunneling machines to deliver today’s result, and we’re only just getting started, as we prepare for construction of the next stage of the Metro project.”

More than 4600 people have worked on this job, most of them from Western Sydney.
