Metro Tunnel

Building Arden Station

Major construction of the Metro Tunnel is underway in North Melbourne.

Arden Station 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 station construction activities will take place 24/7 as the roof slab is installed.

The North Melbourne site will play a key role in supporting the construction of the western section of the Metro Tunnel. The work site will house a number of important facilities including offices, a concrete batching facility, storage areas for the concrete segments that will line the rail tunnels and facilities to manage excavated materials.

The project’s first two tunnel boring machines (TBMs) broke through at Kensington in early 2020 and were returned to Arden Station where they began their journey to Parkville. TBM Joan broke through into the Parkville Station box 20 metres below Grattan Street in late-August 2020 and TBM Meg is not far behind with its breakthrough at Parkville expected in the coming weeks.

Construction look ahead for 2020

Ongoing works

Work at the site of the Arden Station during July and August involves:

  • Tunnelling between North Melbourne and Parkville
  • Station box construction, including concreting of the internal station walls, concourse level and station roof, and removal of struts
  • Slurry treatment plant, water treatment plant and concrete batching plant operation
  • Out of hours oversize deliveries to and from site
  • Utility investigations on Laurens, Barwise and Queensberry streets
  • Surveying, and sampling and testing of groundwater and soil
  • Transporting concrete from the concrete batching plant to other Metro Tunnel Project construction sites
  • Site investigations, site establishment and piling for the North Melbourne electrical substation.

North Melbourne

Utility investigation works

  • Utility investigations will involve the intermittent closure of Laurens and Barwise streets down to one lane. Traffic will be maintained in both directions via a shuttle flow arrangement
  • Some on-street parking spaces may be temporarily impacted on Barwise, Queensberry and Laurens streets
  • Sections of footpath on Laurens Street, adjacent to works, may be temporarily closed during works
  • Access to businesses will be maintained at all times
  • Signage and traffic controllers will be in place to direct vehicles, cyclists and pedestrians around the work area.

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.

Normal construction hours

Work will take place 7am to 6pm, Monday to Friday and 7am to 1pm, Saturdays.

Some activities may be required to continue slightly past these hours. All efforts will be made to complete activities as scheduled.

Managing traffic and transport

The construction of Arden Station will require some 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.

Truck movements and routes during construction

  • Up to 200 trucks per day are expected to travel to and from the construction site.
  • Construction vehicles and trucks will access the site via Laurens and Arden streets.
    • After 6:00pm, all construction vehicles will enter and exit via Arden Street.
  • All trucks carrying excavated materials will be covered, and water carts and street sweepers will be sued to minimise the spread of dust.
  • Rumble grids have been installed to remove debris from the wheels of vehicles to minimise the spread of dirt on local roads.

Asbestos removal

It is not unusual or unexpected for asbestos to be present in demolished industrial sites, as it was commonly used in construction material until the 1980s. Asbestos has been identified at this site and we anticipate that more asbestos will be found as works progress.

Removal of asbestos will be undertaken by qualified personnel, in accordance with WorkSafe Victoria’s Compliance Code 2008 for Removing Asbestos in Workplaces. Removal of asbestos containing materials by licensed removalists does not pose any safety risk to site staff or the public.

TBM assembly and tunnelling

In mid-2019, two tunnel boring machines (TBMs) were assembled at the Arden Station site.
