Bulleen Road interchange checkpoint: structural and traffic design notes for engineers
Reviewed by Joe Ashwell

30 Second Briefing
Works on Victoria’s Bulleen Road interchange have passed the halfway mark after a “mega lift” installed nine large precast beams for the elevated ramp linking the North East Link tunnel to the Eastern Freeway towards Melbourne. This was the third mega lift in 2026, forming a key structural segment of the new grade-separated connection designed to remove weaving movements at the current Bulleen Road–Eastern Freeway interface. Contractors now shift to completing remaining ramp spans, deck works and tie-ins ahead of tunnel commissioning.
Technical Brief
- Nine precast concrete beams were installed in a single coordinated “mega lift” operation.
- Each beam required heavy-lift cranage and night-time possession to minimise disruption on the Eastern Freeway.
- The elevated ramp geometry is constrained by existing Bulleen Road traffic lanes and live freeway carriageways.
- Works are sequenced to maintain traffic flow, with staged closures rather than full shutdowns.
- Beam placement accuracy is critical to achieve the designed grade separation and tie-in to the tunnel portal.
- Precasting off-site reduces on-site formwork and falsework requirements above live traffic.
Our Take
In our database of 915 Infrastructure stories, Victoria-focused road and rail pieces featuring the Victorian Government form one of the densest regional clusters, signalling sustained multi‑corridor investment around Melbourne rather than isolated upgrades.
The Bulleen Road interchange and North East Link tunnel works sit alongside repeated level crossing removals in Macleod and Diggers Rest, indicating that arterial road capacity increases are being paired with grade separation to maintain network performance on Melbourne’s north‑eastern approaches.
For contractors, the concentration of Victorian Government projects covered by Roads & Infrastructure Magazine suggests a relatively predictable pipeline in Melbourne, which can justify maintaining specialised tunnelling and complex interchange capability in the state over several years.
