Melbourne’s Metro Tunnel is set to redefine the city’s transport landscape with the opening of five new underground stations—Arden in North Melbourne, Parkville, State Library, Town Hall and Anzac on St Kilda Road—featuring the city’s first tram–rail interchange. The project brings a distinctive, line-wide architectural approach focused on enduring design, civic identity and public amenity.Unlike traditional underground stations, the Metro Tunnel delivers strong connections to surrounding streets and landmarks, creating a uniquely Melbourne experience at each location. The new precincts also introduce significant public spaces, including the revitalised City Square, enhancing the heart of the CBD.Natural light and air flow are central design principles across the network. At Arden and Parkville, large skylights illuminate concourses, while brick and timber details reflect local character at Arden and Anzac. Anzac Station’s striking elliptical canopy shelters the concourse, opens new daylight-filled connections to platforms and provides weather protection for tram passengers.State Library and Town Hall stations, set deep beneath the CBD, feature vast vaulted interiors designed to create a sense of openness and grandeur despite the depth and urban density. Natural light is also integrated into their primary entrances. A unifying design language runs through all stations: brightly coloured structural elements house key services, while thousands of custom light fixtures and intuitive wayfinding features support seamless navigation.When fully operational in February 2026, the Metro Tunnel will connect the Sunbury, Cranbourne and Pakenham lines through a dedicated tunnel, easing pressure on the City Loop and enabling more frequent services across the network. Strategic interchanges at Town Hall, State Library, Footscray and Caulfield will further improve connectivity.Delivered by the State Government of Victoria through the Victorian Infrastructure Delivery Authority and its project office VIDA Metro, the project has been built by the Cross Yarra Partnership—a public–private partnership comprising Lendlease Engineering, John Holland and Bouygues Construction. Architecture has been led collaboratively by Hassell, WW+P Architects and RSHP. The Metro Tunnel represents a transformative investment in Melbourne’s future, providing essential transport infrastructure, civic landmarks and revitalised public spaces for generations to come.
