Metro Tunnel

Building Arden Station

The new underground station at Arden will be built via a 'cut and cover' method, with the station box excavated from the bottom up and a roof slab placed over the top of the site. Underground construction activities will take place 24/7 once the roof slab has been installed.

The Arden site will also play a key role in supporting the construction of the western section of the Metro Tunnel. Tunnel boring machines (TBMs) will be launched towards the western tunnel entrance in Kensington and the new station in Parkville. The site will house a number of important facilities including offices, storage areas for the concrete segments that will line the rail tunnels and facilities to manage excavated materials.

Construction activities

Key construction activities for Arden Station include:

  • Preparatory works, including demolition of buildings, land clearing and the relocation and protection of underground services such as water, gas and electricity.
  • Site area set up including offices, storm water management, materials storage and access roads.
  • TBM launch site.
  • Excavation of the station box.
  • Structural works, including the station entrance connection to Laurens Street.
  • Architectural, mechanical and electrical fit out.
  • Track works and the installation of signalling and communications systems.
  • Site remediation including landscaping.

Traffic and transport

The construction of the new station at Arden will require changes to local traffic conditions to allow trucks to transport excavated material from site.

Construction traffic routes have been developed that focus on moving trucks and other construction traffic to CityLink as directly as possible. Traffic routes include Laurens Street, Arden Street, Dryburgh Street, Dynon Road and Macaulay Road.

Temporary traffic and cycling diversions in other nearby streets may be required at times to ensure the safety of cyclists and other road users.

Managing construction impacts

Environmental Performance Requirements (EPRs) have been developed in consultation with key stakeholders throughout the Metro Tunnel's planning process to avoid, reduce or manage construction impacts in Arden. Find out more about managing construction impacts.

Construction timeframes

As one of the project's key construction sites, it is estimated that work at Arden will take around eight years.

The target completion date for the project is 2026, 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. MMRA and the construction contractors will work to deliver the project to Victorians as early as possible while maintaining the highest safety and quality standards.
