Metro Tunnel

Building Anzac Station

Construction of Anzac Station is now underway on St Kilda Road.

The station will be built via a cut and cover method, using the ‘top down’ approach.

The walls of the station will first be built into the ground through a series of diaphragm walls, or D-walls. Once the walls of the station are set, excavation equipment will then dig out the top few metres of the station box. A new permanent concrete slab is then poured at this level, forming the roof of the station box. Once the roof is in place, a temporary acoustic shed will be installed over the northern end of the station box, excavation of the station will take place 24/7 under the roof slab and acoustic shed.

Anzac Station will also play a key role in supporting the project's construction activities south of the Yarra River.

Tunnel boring machines (TBMs) will be launched from Anzac Station towards the eastern tunnel entrance in South Yarra, they will be retrieved and taken back to Domain, before being re-launched and tunnelling towards the new underground station at the southern end of Swanston Street.

Construction activities

Key construction activities for Anzac Station include:

  • Tree protection and removal.
  • Relocation of underground services such as water, sewerage, gas, power and telecommunications.
  • Establishment of the tunnelling support site at Edmund Herring Oval.
  • Reconfiguration of St Kilda Road to allow traffic, trams and cyclists to keep flowing around the construction site.
  • TBM launch and support site.
  • Excavation of the station box and construction of a diaphragm wall.
  • TBM launch.
  • Structural works including the station entrance connections.

Construction traffic routes for the St Kilda Road precinct aim to move trucks and other construction traffic between the site and Kings Way / CityLink as directly as possible.

Construction timeframes

It is estimated that construction activities in the Anzac Station precinct will take around five years. Surface disruption is expected to be shorter than the overall construction time. Project wide rail systems installation will occur after this.

The Metro Tunnel is on track to be completed by 2025, which accounts for construction works above and below ground, tunnels and stations fit-out, as well as installation and testing of critical safety systems and the high capacity signalling which needs to be integrated with existing network systems.

The estimated project timelines are due to the scale and complexity of the Metro Tunnel construction, along with Melbourne's challenging ground conditions. Rail Projects Victoria (RPV) and the construction contractors will work to deliver the project to Victorians as early as possible while maintaining the highest safety and quality standards.
