Building Arden Station
Major construction of the Metro Tunnel is underway in North Melbourne.
The Arden Station box has been built using a 'cut and cover' method, with the station box excavated from the bottom up. Construction of the station’s concourse level and internal walls is complete and the roof slab is currently being constructed. Works to prepare for construction of the station entrance will commence in early 2021.
The Arden Station site plays a key role in supporting the construction of the western section of the Metro Tunnel. The worksite houses 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.
Work at the Arden Station site involves:
- TBM and tunnelling support
- Station box construction, including concreting of the 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, Arden 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
- Construction of a station services building to support station operations
- Construction of the North Melbourne electrical substation.
Construction look ahead for 2020/2021
Laurens Street realignment and Arden Station entrance construction
- Laurens Street will be realigned to support service relocations and construction of the Arden Station entrance. This involves the narrowing of traffic and bicycle lanes and closures of sections of footpath and on street parking. These changes will remain in place until late- 2023.

- Piling to support the station entrance structure located on Laurens Street will commence in February, with 31 precast concrete piles to be installed underground. Following piing, crews will start to build the above ground structure.
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.
In mid-2019, two tunnel boring machines (TBMs) were assembled at the Arden Station site. TBMs Joan and Meg have now completed the 1.2 kilometre journey between the Arden Station site and the tunnel’s western entrance in Kensington, and the 1.4 kilometre journey between the Arden Station site and the Parkville Station site.
The Arden Station site plays a key role in supporting the construction of the western section of the Metro Tunnel. The site provides worker access, supplies and concrete tunnel lining segments to the TBMs, and houses facilities to manage material excavated during tunnelling.

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 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 400 trucks per day are expected to travel to and from site.
- Construction vehicles and trucks will access the site via Laurens and Arden streets.
- After 6:00pm, all construction vehicles will enter and exit site 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 and a wheel wash have been installed to remove debris from the wheels of vehicles to minimise the spread of dirt on local roads.
