We’re building the new M80 Ring Road Interchange in Greensborough, with express lanes to the North East Link tunnels and connections for local trips.

We’re working to remove the traffic lights at the existing M80 Ring Road intersection to ease congestion and slash travel times. Four new lanes and smart technology from Plenty Road to the new Interchange will also deliver faster, safer trips for drivers.

The new Interchange will seamlessly connect the M80 Ring Road to the Greensborough Bypass and express lanes to North East Link.

The M80 Ring Road Interchange ramps and overpass bridges are carefully designed to minimise visual and noise impacts to residents nearby.

This fact sheet provides an overview of the new Interchange design and outlines how we build it in stages to minimise disruptions to traffic.

How we're building the new M80 Ring Road Interchange

We’re building the new Interchange in stages and progressively opening new sections to traffic, to reduce construction impacts and disruptions.

Stage 1: Create space and prepare to build the Interchange.

In 2024, we started relocating utility services, installing drainage and excavating along the M80 Ring Road and Greensborough Bypass to make space for new lanes.

In early 2025, we moved M80 Ring Road traffic onto new lanes, allowing us to access new work areas and continue constructing new ramps and bridge structures behind barriers. We also started installing noise walls along the M80 Ring Road and Greensborough Bypass to reduce construction impacts early in the project for residents nearby.

Stage 2: New temporary M80 Ring Road Interchange

In September 2025, we moved traffic onto new lanes along the M80 Ring Road and the temporary intersection at the M80 Ring Road Interchange. This will be in place for up to 18 months, so crews can continue building new Interchange structures and bridge foundations safely behind barriers.

As part of this traffic switch, drivers are using newly built roads for the first time along the M80 Ring Road and Greensborough Bypass, including an upgraded M80 Ring Road exit to Hurstbridge.

We’ve also been building road bridges that will form the new connection to the M80 Ring Road from Grimshaw Street. The first permanent road bridge opened to drivers in September 2025, taking northbound Greensborough Bypass traffic to the M80 Ring Road.

Stage 3: Major works to build key structures

From 2025 to late 2026, we’ll continue working on key structures that will make up the new M80 Interchange including ramps, bridges, underpasses and flyovers.

Driving along Greensborough Bypass, you may have noticed a large structure standing tall at the current M80 Interchange. This will form the flyover bridge which will take traffic from Hurstbridge onto the M80 Ring Road.

We’ll start building the new northbound underpass to Hurstbridge and the southbound Greensborough Bypass lanes to Grimshaw Street.

The new, wider Macorna Street walking and cycling bridge will be built in stages to reduce disruption. In late 2026, we’ll lift the new bridge structure into place over the road and demolish the old one shortly after it opens to pedestrians.

Stage 4: Move traffic onto new structures to create space for new work areas

From late 2026 through 2027, we’ll progressively move traffic onto new sections of the M80 Ring Road and Greensborough Bypass. Multiple new structures will open to traffic for the first time, including the flyover bridge at the Interchange, creating a seamless connection from Hurstbridge to the M80 Ring Road.

Greensborough Bypass traffic will be able to travel on the new northbound underpass to Hurstbridge without having to stop at traffic lights. Southbound traffic will use temporary lanes to connect to Grimshaw Street, as we prepare to build the express lanes to North East Link tunnels.

Switching traffic allows us to keep building other key structures such as ramps, underpasses and bridges.

Stage 5: Build express lanes to NEL and more key Interchange structures

With traffic on new structures and upgraded sections of the Interchange, we’ll have space to build the new overpass connection to Grimshaw Street from the M80 Ring Road.

We’ll then build the express lanes, connecting the M80 Ring Road and Greensborough Bypass to the North East Link tunnels, completing the seamless Interchange.

Stage 6: Finishing works and project completion

The new M80 Ring Road Interchange will fully open in 2028, complete with express lanes to North East Link, skipping traffic lights and slashing travel times.

We’ll complete finishing works on the M80 Ring Road and Greensborough Bypass, including final road surfacing and landscaping, and setting up the smarter Freeway Management System.

We’ll also open the new walking and cycling underpasses at Yando and Kempston streets, connecting you to improved green spaces at AK Lines and Trist Street reserves.

New Ring Road wetlands

A smarter lane layout for the new M80 Ring Road Interchange has created more space for trees, plants and new wetlands. The wetlands will store and clean rain water and create a new habitat area between Plenty Gorge and Plenty River.

Underpasses at Yando and Kempston streets

New brighter and wider walking and cycling underpasses will be built at Yando Street, Greensborough and Kempston Street, Watsonia to help locals get around. The Kempston Street underpass will also be kept open for cars.
