Melbourne Metro Tunnel


Melbourne Metro Tunnel

The $13.5 billion Melbourne Metro Tunnel project represents a doubling of the size of the city’s underground rail. The project comprises: nine kilometres of twin rail tunnels connecting the Cranbourne, Pakenham and Sunbury lines; five new underground stations at Arden, Parkville, State Library, Town Hall and Anzac; and a tram/train interchange at Anzac Station. The project was delivered through a combination of Public Private Partnership and alliance contracts.

The Judging Panel shortlisted the project for its impact on Victoria’s passenger rail network, improving connectivity and servicing key suburban growth corridors. The Panel also recognised the longevity of the project’s partnerships and the collaborative, integrative approach undertaken across the four major packages to deliver the project.
