Shortlisted contractors can now submit a Request for Proposal (RFP) for Package 2 of the Tonkin Highway Extension and Thomas Road Upgrade, achieving another major milestone for the project.

The extension of Tonkin Highway will provide a non-stop transport link between Oakford and Mundijong, reducing traffic pressure on local roads, and provide better connections for car drivers and heavy vehicles.

Procurement has been split into two contract packages that will be delivered at the same time. Package 2 incorporates the Tonkin Highway extension from Mundijong Road to South Western Highway.

The shortlisted consortia comprise of the following companies:

• Tonkin Connect Alliance comprising: CPB Contractors, WA Limestone, Carey, Aurecon and Jacobs;
• Tonkin Extension Alliance comprising: BMD, Georgiou, Civcon, GHD and BG&E; and
• Tonkin South Alliance comprising: Acciona, NRW, AECOM and Arup.

An Alliance Contract for Package 2 is expected to be awarded by late 2024. The RFP process asks shortlisted contractors to submit detailed proposals on how they will design and construct the project, including pricing and key milestone dates.

Package 1 of the Tonkin Highway Extension and Thomas Road Upgrade Project closed late June 2024 and is being evaluated to allow for award of the alliance contract later this year.

Construction of the Tonkin Highway Extension and Thomas Road Upgrade will start in mid-2025.

The project will support around 4,400 direct and indirect jobs during the construction phase.

Over $1 billion is allocated to deliver the project, with the Australian and Western Australian Governments committing $749 million and $296 million respectively.

Project Overview

The Tonkin Highway Extension is designed to extend the highway from its current terminus at Thomas Road in Oakford to South Western Highway in Mundijong. This extension is expected to significantly improve traffic flow, reduce travel times, and support the economic growth of the surrounding regions. The project is part of the broader effort to upgrade and expand Perth’s road network to accommodate the city’s growing population and increasing transport demands.

Objectives and Benefits

One of the primary objectives of the Tonkin Highway Extension Project is to provide a more direct and efficient route for vehicles traveling between Perth’s northeastern and southwestern suburbs. This new route aims to divert traffic from local roads, thereby reducing congestion and enhancing safety for local communities. Additionally, the extension is expected to facilitate better access to industrial areas, promoting economic activities and supporting local businesses.

The project is also set to bring substantial environmental and social benefits. By improving traffic flow and reducing congestion, the extension will help lower vehicle emissions, contributing to better air quality. Moreover, the project includes provisions for wildlife crossings and green corridors to mitigate the impact on local ecosystems and biodiversity.

Project Components

The Tonkin Highway Extension Project comprises several key components. These include the construction of new interchanges, overpasses, and bridges to ensure seamless connectivity and enhance road safety. The project also involves extensive road widening and the installation of modern road infrastructure such as intelligent transport systems (ITS) to manage traffic efficiently.

Timeline and Funding

The project is being implemented in stages, with detailed planning and environmental assessments preceding construction activities. The Western Australian and Australian governments are jointly funding the project, highlighting its significance to the region’s infrastructure development. Construction is expected to commence in the near future, with completion targeted within the next few years.
