North East Link – Melbourne’s Major Infrastructure Project

Melbourne’s ambitious North East Link represents the city’s most significant infrastructure undertaking in decades. The 10-kilometre tolled highway will connect the M80 Metropolitan Ring Road at Greensborough to the Eastern Freeway at Bulleen, threading through twin three-lane tunnels beneath Banyule Flats and the Yarra River. When completed, the project will finally seal the orbital ring road network that urban planners have envisioned since the 1920s.

Victoria’s Big Build program has positioned this undertaking at its centrepiece, allocating resources that dwarf any previous road project in the state. The development has attracted both support for its promised traffic relief and scrutiny regarding its environmental footprint and community impact.

North East Link at a Glance: Key Project Statistics

What the North East Link Aims to Deliver

The project targets substantial improvements to Melbourne’s northern road network. Traffic modelling indicates the initiative could remove approximately 15,000 trucks from local roads daily, providing relief to residential streets that currently bear heavy through-traffic burdens.

• Twin three-lane tunnels will add significant capacity to the northern corridor
• Travel times between key points may be reduced by up to 35 minutes
• The Eastern Freeway will be widened to accommodate increased traffic volumes
• A new Yarra River crossing will complement existing infrastructure
• Integrated Doncaster Busway will support public transport options
• Approximately 34 kilometres of walking and cycling paths planned

The Route: From Greensborough to Bulleen

The selected western alignment, designated Route A, traces a path through Melbourne’s northern suburbs before descending into tunnel sections. Beginning at the Greensborough interchange with the M80, the route passes through Watsonia and Rosanna, emerging to connect with the Eastern Freeway at Bulleen Road.

Tunnel Sections and Engineering Challenges

Tunnelling extends from Lower Plenty Road through to the Eastern Freeway, with the critical section passing 40 to 45 metres beneath the Yarra River bed. Engineers extended the underground portion by 1.9 kilometres compared to earlier proposals, opting for additional tunnelling to minimise surface disruption to sensitive environmental areas.

Surface Infrastructure and Interchanges

Above ground, the project includes significant urban design elements. Greensborough Road will feature a tree-lined boulevard, while a green bridge will carry pedestrians and cyclists over the main carriageway. Key interchanges include connections to the M80 (serving Seymour and Melbourne Airport routes), the Greensborough Bypass on State Route 46, and Grimshaw Street via a single-point urban interchange design.

Why Alternative Routes Were Set Aside

Planning documents from 2008 evaluated several corridor options before recommending the western alignment. A central route would have passed through Eltham and Warrandyte toward EastLink, while an eastern option proposed alignment through Kangaroo Ground and Chirnside Park. According to the technical analysis by GHD, budget constraints and engineering feasibility assessments favoured the selected western tunnel corridor.

Timeline: From Announcement to Opening

The North East Link has progressed through distinct phases since its initial announcement. The Victorian Government first pledged support in 2016, with early cost estimates of $10 billion. The project subsequently moved through planning approvals, environmental assessment, and procurement stages before breaking ground.

Construction Phases and Current Progress

Early works commenced in 2020, establishing site compounds, relocating utilities, and conducting geotechnical investigations. Major tunnelling operations began in mid-2024 with tunnel boring machines now operating along the alignment.

The project encompasses not only the central highway corridor but also substantial upgrades to connecting infrastructure. The Eastern Freeway will be widened to 20 lanes in sections, the M80 Ring Road receives enhancements, and the Doncaster Busway integrates public transport options. Approximately 25 kilometres of walking and cycling paths form part of the overall scope.

Project Benefits and Economic Impact

Proponents argue the North East Link will deliver meaningful improvements to Melbourne’s transport network. The primary benefits centre on reduced congestion and improved freight efficiency across the northern region.

Capacity and Connectivity Improvements

The twin three-lane tunnels will accommodate substantial traffic volumes, complementing smart motorway technology throughout the corridor. Park-and-ride facilities, including a $69 million development at Bulleen, aim to encourage modal shift for commuters travelling toward the CBD.

Freight operators stand to benefit significantly from the new connection. The ability to bypass local roads removes heavy vehicles from residential neighbourhoods while providing a more efficient route for commercial traffic moving between eastern and western Victoria.

What We Know and What Remains Unclear

Community and Environmental Considerations

The North East Link traverses environmentally sensitive areas, prompting careful attention to minimising surface impacts. Tunnel depths of up to 40 metres beneath the Yarra River protect batters and surrounding ecosystems from construction disturbances. The project incorporates noise walls along substantial portions of the alignment and includes wetland restoration components.

Community engagement has occurred throughout the planning process, with the project team maintaining information channels through northeastlink.vic.gov.au. The Urban Design and Landscape Plan outlines proposed parklands extending from Watsonia through to Bulleen, with particular emphasis on recreational spaces adjacent to the Yarra River corridor.

Technical Advisory Perspective

Engineering consultancy GHD has supported the project through reference design, environmental effects assessment, and approvals processes. Their work has examined engineering feasibility, contamination investigations, and urban design integration across the corridor.

Looking Ahead: What Comes Next

With tunnelling now underway, attention shifts to the complex underground works that will consume the coming years. The Yarra River crossing presents particular engineering challenges given the depth and ground conditions involved. Surface works will continue concurrently, with bridge construction, interchange completion, and landscaping progressing throughout the corridor.

The Doncaster Busway component remains an integral part of the overall project scope, designed to provide public transport options that complement the new road capacity. Monitoring of construction progress will continue as the project moves toward its 2028 completion target.
