Major construction of the Melbourne Metro Tunnel Project’s five new underground stations is ramping up as tunnelling nears completion.
Only one tunnel boring machine (TBM) is currently digging, excavating the final portion of the nine-kilometre tunnels from Kensington to South Yarra.
Arden Station’s platforms and brick arches are beginning to take shape, with the station’s internal walls now in place.
The first concrete pour to build the station’s platforms has taken place, with platform construction continuing with the installation of pre-cast platform units and further concrete pours.
Construction on the roof slab is near completion and crews have begun to install mechanical, electrical, and plumbing services in the station box.

Earlier this year, workers installed 38 piles deep into the ground surrounding the eastern end of the station to reinforce the entrance building’s foundations.
Arden Station’s entrance will feature 15 brick arches, which are being built off-site. More than 100,000 bricks will be laid by hand onto precast concrete and delivered over the next few months.
The arches spanning the entrance are a reference to the industrial history of Melbourne’s inner north. They will be made up of 52 concrete segments, each weighing 45-50 tonnes and lined with 104,000 bricks.
The bricks were manufactured in Victoria, then transported to a concrete manufacturer in South Australia where they are being laid by hand into the precast concrete segments.
Arden Station will have a direct link to the Airport in 2029 and be within walking distance of the North Melbourne Recreation Centre, Arden Street Oval and the route 57 tram.
The design prioritises pedestrian safety, with pedestrian crossings on Arden Street and Laurens Street, and includes new drop-off zones and taxi bays directly outside the station, and more than 120 bike parking spaces.
“The Metro Tunnel will not just deliver more trains, more often – but a new precinct that will have a direct link to the airport, attract thousands of jobs and provide another place for Victorians to live,” Transport Infrastructure Jacinta Allan said.
“As tunnelling is about to wrap up – the team has a massive task ahead of them to finish the stations, lay the track and get the tunnel ready to deliver more trains, more often.”
