Major construction underway on $225m Reid Highway Interchanges Project

Major construction has commenced on the $225 million Reid Highway Interchanges Project in Western Australia, which is jointly funded by the Australian and Western Australian Governments on a 50:50 basis. 

This project will help improve safety and efficiency in Perth’s north east suburbs by delivering two new grade-separated interchanges that will replace the existing signalised intersections at Altone Road and Drumpellier Drive/Daviot Road. 

Not only will this upgrade improve safety and connectivity for local communities, but it will also enhance freight efficiency by removing two of the remaining five sets of traffic signals on Reid Highway. 

“The upgrades to the Reid Highway are about providing a safer and more efficient journey for people driving, but also walking and cycling. 

“The changes to intersections will also make it safer and faster for heavy vehicles to travel through Perth’s north east,” Federal Infrastructure, Transport, Regional Development and Local Government Minister Catherine King said. 

“Reid Highway is one of Perth’s most important east-west links, and these new interchanges will make a significant difference for residents, businesses, and freight operators moving through our northern-eastern suburbs. 

“The transformation of these intersections will deliver smoother, safer journeys while improving access for cyclists and pedestrians in the area. 

“The $225 million joint investment is part of the Cook Government’s commitment to strengthen connectivity across Perth’s north and ensuring our transport network keeps pace with this fast growing region,” WA Transport Minister Rita Saffioti said. 

The current scope of the project includes: 

• A new bridge on Reid Highway, passing over Altone Road intersection, with connectivity between Altone Road and Reid Highway to be maintained via entry and exit ramps and roundabouts 

• A new bridge connecting Drumpellier Drive with Daviot Road over Reid Highway with entry and exit ramps onto Reid Highway 

• Modifications to Reid Highway from Altone Road to Arthur Street to support the new interchanges 

• Modifications to the existing Tattler Way roundabouts to provide southbound left in / left out access to residential areas 

• A Principal Shared Path (PSP) bridge for cyclists and pedestrians passing over the Altone Road on ramp and new PSP underpasses beneath the Altone Road off ramp and Daviot Road. Collectively these upgrades will provide an uninterrupted path network from West Swan Road to Malaga Drive 

• Landscaping and urban design 

In mid 2025, Georgiou Group was awarded the contract to design and construct the Reid Highway Interchanges Project. 

“We’re focused on delivering real improvements for the Cowan community. Better transport links mean safer roads and more reliable connections, making everyday life easier for local families. 

“This project is another great example of how we’re investing in Cowan and delivering the infrastructure and upgrades falimies, workers and local businesses need,” Federal Member for Cowan Anne Aly said. 

“This project is a significant investment in safety and connectivity for communities across Perth’s north east, including many people in Hasluck who rely on Reid Highway every day. 

“Removing traffic signals and delivering grade-separated interchanges will reduce congestion, improve travel times and support our local commuters. 

“The upgrades for cyclists and pedestrians, including the uninterrupted shared path to the Swan Valley, will also deliver real benefits for local families,” Federal Member for Hasluck Tania Lawrence said. 

Works are being carried out within a tight footprint which requires modifications to Reid Highway and surrounding intersections while construction is underway. Measures are put in place to ensure people can move safely and efficiently. 

More details on detours, traffic changes and road closures can be found on Main Roads Western Australia website. 

The Reid Highway Interchanges Project is part of the Australian and Western Australian Governments’ commitments to delivering quality infrastructure and services for the State. 

“These upgrades will be a game-changer for our community, helping to ease congestion and significantly improve safety at these busy intersections. 

“Grade-separated interchanges will enhance the flow of traffic along this critical freight route and help to reduce travel times for locals. 

“Temporary changes to the local road network will be needed to safely complete construction and we’ll continue to keep the community informed as it progresses,” State Member for Bassendean Dave Kelly said. 

“We appreciate the community’s patience as construction ramps up, and we’ll continue to work with residents to minimise the impact of roadworks on the surrounding areas. 

“Removing signalised intersections will mean less interruptions for commuters and freight moving through this fast-growing part of Perth. 

“The upgrades will also make it easier to access the beautiful Swan Valley, providing an uninterrupted path network for cyclists and pedestrians from West Swan to Malaga Drive which is set to deliver great benefits for the local tourism economy,” State Member for Midland Steve Catania said.
