NRW Locks in $200M Perth Highway Upgrade With No Capital Outlay Required
NRW Holdings (ASX: NWH) has been awarded the Tonkin Highway Grade Separations, Hale Road and Welshpool Road East project by Main Roads Western Australia, with the contract valued at approximately $200 million. The project forms part of the broader Tonkin Highway Corridor upgrades from Roe Highway to Kelvin Road, aimed at improving safety and reducing congestion along one of Perth’s most heavily trafficked routes.
NRW Tonkin Highway Contract Award strengthens civil infrastructure pipeline
The contract has been awarded to NRW Contracting Pty Ltd, a wholly owned subsidiary of NRW Holdings. Main Roads Western Australia selected NRW Contracting to deliver the complex civil infrastructure project, which will upgrade Tonkin Highway to three lanes in each direction and introduce grade-separated interchanges to eliminate conflict points and improve traffic flow.
The approximately $200 million contract represents a material addition to NRW’s civil construction work-in-hand, reinforcing the company’s position as a preferred contractor for major government infrastructure projects in Western Australia. The project is capital-light, requiring no material capital outlay from NRW.
Design and procurement activities are expected to commence immediately following contract execution, with construction scheduled to begin in Q4 2026. This timeline provides visibility over NRW’s civil construction workload extending into the second half of the decade.

Project scope and construction timeline
The Tonkin Highway Grade Separations project encompasses a comprehensive range of civil infrastructure works:
- Reconstruction and widening of Tonkin Highway to three lanes in each direction
- Diamond interchange at Welshpool Road East
- Principal Shared Path on eastern side including underpasses
- U-turn facility on Welshpool Road East
- Road and shared path lighting
- Foundation Intelligent Transport Systems
- Noise mitigation treatments
- Service relocations including Western Power
- Modifications to local government roads and intersections
- Accommodation works
- Design of Optional Works
Construction is scheduled to commence in Q4 2026 following immediate commencement of design and procurement activities. The project’s multi-faceted scope plays to NRW’s core capabilities in complex civil infrastructure delivery, including bulk earthworks, road construction, and service coordination.
Importantly, there is no material capital outlay required in relation to this contract, preserving NRW’s balance sheet flexibility whilst securing a substantial revenue stream.
Optional works provide additional upside potential
Beyond the base scope, NRW Contracting has submitted a separate price for Optional Works associated with the project. These optional works include a further grade separation at Hale Road, with partial connection to Tonkin Highway through north-facing ramps.
The Optional Works are subject to Main Roads Western Australia exercising the option to proceed. If exercised, these works would extend the project duration and contract value beyond the base $200 million figure without requiring NRW to compete in a new tender process.
This embedded optionality provides potential upside whilst maintaining cost certainty for the client and revenue visibility for NRW.
What is a grade separation and why does it matter for infrastructure investors?
A grade separation is an engineering solution that separates intersecting roads or rail lines at different levels, typically using bridges or underpasses. Unlike traditional at-grade intersections controlled by traffic lights, grade separations allow traffic to flow continuously without stopping.
Governments invest in grade separations to improve safety by removing conflict points where vehicles cross paths, reduce congestion by eliminating traffic light delays, and enhance capacity on major transport corridors. For metropolitan areas experiencing population growth, grade separations are a critical tool for managing traffic volumes without acquiring additional land for road widening.
From an investor perspective, grade separation projects are typically high-value, multi-year contracts awarded to contractors with proven capability in complex civil construction. The technical complexity, coordination requirements, and safety standards involved create barriers to entry that favour established operators like NRW Holdings.
Management commentary on strategic positioning
Jules Pemberton, CEO and Managing Director
“Securing this project further underpins NRW’s civil construction work-in-hand and provides continuity of work for our people and supply partners. We look forward to working collaboratively with Main Roads Western Australia and key stakeholders to deliver a high-quality outcome, while maintaining our focus on safety, sustainability and operational excellence.”
Pemberton highlighted NRW’s strong track record in the delivery of complex, large-scale civil infrastructure projects across Western Australia and the company’s established relationship with Main Roads. He described the Tonkin Highway corridor as critical transport infrastructure for Perth, with the project delivering significant safety and congestion-relief benefits for road users, cyclists and the surrounding community.
The CEO’s emphasis on work continuity for NRW’s workforce and supply partners underscores the strategic value of securing large-scale government contracts that provide multi-year visibility.
