Gateway WA

Perth Airport & Freight Access


Project Overview

The Gateway WA Perth Airport and Freight Access Project is the largest infrastructure project ever undertaken by Main Roads WA.

This billion-dollar project involves a major upgrade to the road network surrounding Perth Airport and the freight and industrial hubs of Kewdale and Forrestfield.

It focuses primarily on Tonkin Highway, between Great Eastern Highway and Roe Highway, and Leach Highway, between Orrong Road and Perth Airport.

The need for this project has been driven by the expected doubling of passenger air travel and the road freight task over the next decade, coupled with proposed consolidation of the Perth airport terminals.

The Gateway WA Project Map is available to download.

This area of Perth is arguably Western Australia’s most important transport interchange, where road, rail and air services meet to facilitate the movement of people and goods that are essential to the economy of both the state and the nation.

The Gateway WA upgrade commenced in 2013 and is expected to be completed by 2017, ahead of the planned consolidation of the domestic and international terminals at the Perth Airport. A video recording of theFflyover for the Gateway WA Project Master Plan is available to view.

Stakeholder and Community Consultation

Stakeholder and community consultation is a key component of the project and involves a broad range of engagement activities, including:

  • A Community Liaison Group
  • Public displays
  • Meetings with local residents and businesses
  • Project newsletters regularly distributed to local households and businesses
  • Newspaper advertising and advertorials
  • Regular meetings of technical advisory groups, addressing specific issues such as freight, environmental impacts, drainage and urban design.

Gateway WA will build on its engagement and seek further stakeholder and community input on issues such as construction methodology and staging, traffic management, access during construction, urban design and landscaping.



The project is being jointly funded with the Federal Government contributing up to $686.4 million as part of the Regional Infrastructure Fund and Nation Building Program. The State Government is contributing $317.5 million.


Project Scope

The scope of the Gateway WA project is outlined in a Project Master Plan, which is the result of a two-year planning study undertaken by Gateway Vision (a joint venture between consultants GHD and BG&E) on behalf of Main Roads WA. This study involved significant community and stakeholder consultation.

Construction is scheduled to commence in 2013, with project completion expected by 2017 prior to consolidation of the domestic and international airport terminals.

The project includes:

  • A major freeway-to-freeway interchange at Tonkin Highway-Leach Highway, including a new primary access road to the consolidated airport terminal
  • A new interchange at Tonkin Highway-Horrie Miller Drive-Kewdale Road
  • A new interchange at Leach Highway-Abernethy Road
  • Upgrading Leach Highway between Orrong Road and Tonkin Highway to an expressway standard and associated upgrades to local roads and intersections in the Kewdale area
  • A principal shared path along Tonkin Highway and Leach Highway
  • Upgrading of the existing Tonkin Highway-Roe Highway interchange to a partial freeway to freeway interchange
  • Upgrading Tonkin Highway between Great Eastern Highway and Roe Highway to six lanes
  • A new interchange at Boud Avenue (subject to further funding negotiations)


Project Objectives

The Gateway WA Project is a national infrastructure priority driven by the expected doubling of the freight task and passenger air travel between now and 2031. Infrastructure Australia identifies the Gateway WA project as a nationally significant project under its Competitive International Gateways goal to improve Australia's trade performance.

The Gateway WA project will achieve the following two primary objectives:

  • Improve and secure access to Perth Airport to complement the airport redevelopment and, in doing so, provide sufficient capacity to handle the expected growth in transport demand; and
  • Improve the operational efficiency of freight vehicles including those servicing the national significant intermodal freight terminals at Kewdale and Forrestfield.

Other key objectives include:

  • Provide a "Gateway" access to the proposed new Perth Airport and to the state of Western Australia that will leave a favourable impression for road users through and efficient, legible and pleasing road journey;
  • Improve safety in keeping with the State Government's "Toward Zero" road safety initiative;
  • Improve the efficiency of the road network with grade-separation and extra lanes - resulting in reduced congestion, travel times, freight costs, fuel consumption and emissions;
  • Minimise adverse impacts to the environment, road and path users, local businesses and residents;
  • Respect the significance of the natural environment and Aboriginal Heritage; and
  • Provide the foundation for enhancing public transport services to the airport and freight precinct.


Planning Process

Planning for the Gateway WA Perth Airport and Freight Access Project commenced in mid-2010, when Main Roads awarded Gateway Vision a contract to undertake a comprehensive planning study.

As a result of this study, a visionary Concept Plan was developed that identifies the long term road layout required to meet the transport needs of the year 2031 and beyond.

This Plan has been tested to ensure that it can meet the needs of a future Perth population of 3.5 million.

The Project Master Plan details the more immediate road upgrades required to support the steady growth of the Perth Airport and Kewdale freight precincts. It outlines the proposed scope of the project.

As far as practicable, the reservation proposed for the project minimises impacts to environmentally significant areas and private property. However, in some areas it will be necessary to amend the Metropolitan Regional Scheme and acquire privately-owned land.
