THE Gateway WA Consortium, comprising Leighton Contractors, Georgiou, GHD, AECOM and BG&E, has been chosen as the preferred alliance partner to deliver the billion dollar Gateway WA project, with construction work expected to commence early next year.
Gateway WA, the largest infrastructure project ever undertaken by Main Roads WA, involves a major upgrade to the road network surrounding Perth Airport and the freight and industrial hubs of Kewdale and Forrestfield.
The project includes:
- A freeway-to-freeway interchange at the Tonkin and Leach Highways intersection, with free flowing movements in all directions, and includes a major new access to the international terminal;
- An interchange at the Tonkin Highway, Horrie Miller Drive and Kewdale Road intersection;
- An interchange at the Leach Highway and Abernethy Road intersection;
- Upgrade of the existing interchange at the junction of the Tonkin and Roe Highways to a partial freeway-to-freeway interchange;
- Widening of the Tonkin Highway to six lanes between the Great Eastern and Roe Highways; and
- Upgrade of the Leach Highway to 'expressway standard' between the Tonkin Highway and Orrong Road, maximising the benefits of the Leach Highway and Abernethy Road interchange.
Federal Infrastructure and Transport Minister Anthony Albanese said officials from Main Roads WA will now begin detailed negotiations with the Consortium with a view to finalising contractual arrangements before the end of the year.
"Assessed by Infrastructure Australia and placed on its 2010 National Priority List, this project was one of our key pledges at the last Federal election and we are determined to make it happen," Mr Albanese said.
Western Australian Transport Minister Troy Buswell said the scope of the project was outlined in the Gateway WA Project Master Plan, which was developed in close consultation with industry and the local community.
"The Master Plan identified a series of much-needed improvements around the Airport as well as the nearby Kewdale and Forrestfield industrial estates, including extra lanes on the Tonkin Highway, new interchanges and the upgrade of Leach Highway to an expressway," Mr Buswell said.
"This precinct is one of the State's most important transport hubs, facilitating the movement of people and freight essential to our ongoing industrial development. But unfortunately, this junction point between road, rail and air services is not fit for purpose."
The Minister said by fixing the road network around the Airport, the Gateway project will reduce urban congestion in Perth and improve the efficiency and reliability of the supply chain on which regional communities depend.
The Gateway WA project is being jointly funded, with the Federal Government contributing up to $686.4 million. The entire upgrade is expected to be completed by 2017, ahead of the planned consolidation of the domestic and international terminals.
Land acquisition process for the project commenced earlier this year and due to the project's size, scale and complexity, construction is likely to be staged to minimise disruption.
