Roadheader breaks through at Town Hall Station

Roadheader at Town Hall Station

On 5 August, one roadheader broke through at Town Hall Station, completing the first level of the rail tunnels that will run alongside the station’s platform.

The roadheader will now dig another 7 m to complete the tunnels as major excavation for all five new underground stations near completion.

According to Metro Tunnel’s official website, the station will be longer than a city block and as deep as a five-storey building

More than 120,000 m3 of soil and rock have been dug at the site by three roadheaders, with excavation now more than 75 per cent complete.

The station will have direct underground links to Flinders Street Station, Federation Square and City Square.

The completed station will run 33 m below street level with its platform level at 27 m below ground.

A total of seven roadheaders are being used in the creation of the Town Hall and State Library stations.

Tunnel boring machine (TBM) retrieval began back in late July, with machines reaching Town Hall Station back in May.  

The Metro Tunnel is due to be completed in 2025.
