$400m Tonkin Gap contract awarded by State Government


A $400 million contract has been awarded by the Western Australian Government to fix a bottleneck on Tonkin Highway, fast-tracking the project to create thousands of construction jobs. 

The Tonkin Gap alliance was recently awarded the contract. The alliance is comprised of BMD, Georgiou Group, WA Limestone, BG&E and GHD. 

The recently-formed alliance will work with PTA and Main Roads to execute the project. The works are expected to create more than 3,000 jobs.

The project will remedy a major bottleneck on the Tonkin Highway through Bayswater which sees more than 120,000 vehicles pass through it every day. The project includes works from Collier Road to Dunreath Drive. 

It is tipped to save 17,000 road users who use this section of Tonkin Highway up to six minutes during morning peak and as much as eleven minutes during the afternoon peak.

Included in the project's features are noise walls and amenities, as well as a new principal shared path for cyclists and pedestrians. 

While fixing one of Perth’s most congested bottlenecks, the project also includes rail-enabling works for the METRONET Morley-Ellenbrook Line, including the construction of underpasses and dive structures, to enable trains to enter and travel through the median strip of Tonkin Highway then exit in Malaga.

In addition, road and bus bridges will be built at Broun Avenue to facilitate access to the future Morley Station and formation works for the rail line.

The project includes:

  • Additional traffic lanes in each direction between Collier Road and Dunreath Drive
  • New bridges over the Swan River, Guildford Road, Railway Parade, the Midland Line railway and Dunstone Road
  • Upgrades to the Guildford Road and Great Eastern Highway interchanges
  • A Principal Shared Path with bridges, underpasses and local connections for cyclists and pedestrians
  • Noise walls, lighting and amenity improvements

WA Premier, Mark McGowan, said the project formed part of a pipeline of major road projects for Western Australia, worth an estimated $2.37 billion and creating more than 13,000 jobs.

“This is one of WA’s most congested sections of roads – I’m glad we have been able to fast-track works and help support the WA economy in the process,” Mr McGowan said.

“As our economy begins to recover from the effects of COVID-19, it’s important we keep major infrastructure projects moving – to build and develop communities for generations to come and to support local workers in jobs.

“This year alone we have seven METRONET projects under construction, as well as several others in the planning phase, creating local jobs and providing opportunities for local businesses.”


WA Transport Minister, Rita Saffioti, said this was one of the major road projects the WA Government had worked to fast-track to help the economy recover from COVID-19.

“This project will fix a bottleneck that more than 120,000 vehicles travel through daily as well as provide some of the key works for the major Morley-Ellenbrook Line along Tonkin Highway,” Ms Saffioti said.

“When complete, afternoon commuters travelling northbound on Tonkin Highway between Morley Drive and Dunreath Drive will save up to eleven minutes on their daily drive, meaning they can spend less time on our roads and more time with friends and family.

“Building this project, combined with construction of other nearby major projects like the new Bayswater Station and Morley-Ellenbrook Line, will help support the WA economy through some tough times ahead.”

Federal Minister for Population, Cities and Urban Infrastructure, Alan Tudge, said the Federal Government had prioritised the critical infrastructure.

“It’s crucial that we support the WA economy as we come out the other side of COVID and fast-tracking projects like the Tonkin Highway Gap is part of our plan,” Mr Tudge said.
