The Metro Tunnel Project in Melbourne has achieved a major milestone, with the project’s first tunnel breakthrough. Three massive machines called roadheaders – each weighing more than 100 tonnes – have met 300 metres underground after months of around the clock excavation.
The roadheaders have been mining station caverns and underground passenger connections under Swanston Street, for the new State Library Station.
Five new underground stations and twin 9km rail tunnels are being built through the centre of Melbourne, as part of Victoria’s biggest ever public transport infrastructure project.
The design for the five stations is a world class collaboration between leading international design practices HASSELL, Weston Williamson and Rogers Stirk Harbour and Partners, as part of CYP Design & Construction Joint Venture.
