Gateway WA

Gateway WA

Gateway WA will deliver an efficient road and bridge network to the new Perth Airport precinct, surrounding businesses and residential areas, and the rapidly growing transport and logistics operations in the area. 

The $1 billion project is the largest infrastructure project ever undertaken by Main Roads, working to improve the safety and efficiency of one of the State’s most important transport hubs. 

The project will involve a major upgrade of Tonkin Highway (between Great Eastern Highway and Roe Highway) and Leach Highway (between Orrong Road and the Perth Airport), as well as the construction of five new grade separated interchanges.

The project will form an iconic gateway to Perth that will create a lasting impression for road users, residents and visitors to Western Australia.

Works Updates

The Abernethy loop to Tonkin Highway is now open. The loop will provide immediate relief to the freight industry by cutting 3.7km off the current transport route to the regional network. 

The new loop will allow traffic direct access to Tonkin Highway (southbound) from Abernethy Road in Forrestfield.

Road users, in particular freight operators, will no longer need to wait at the heavily congested intersections of Leach Highway or Kewdale Road/Horrie Miller Drive in order to travel southbound on Tonkin Highway or to connect to Roe Highway.

An eight bay road train assembly and inspection area is currently being constructed adjacent to the Abernethy loop and is anticipated to be operational by early 2014, greatly improving safety and amenity for the freight industry.  

The local road modifications being undertaken as part of the Gateway WA Project, including upgrades to many of the key intersections in Kewdale, will improve connectivity and reduce travel times for the transport industry. 

Commencing in the coming months, the intersection upgrades will be constructed in stages and are anticipated to be completed by mid 2015.

Delivery Phases

  1. Clearing of the three main interchanges (Leach/Abernethy, Leach/Tonkin and Tonkin/Horrie Miller) is underway.  New traffic management arrangements are being progressively implemented throughout the project area.
  2. First package of work - the Abernethy loop ramp is now open. 
  3. The full scope of works is expected to be completed by 2017, ahead of the planned consolidation of the domestic and international terminals at the Perth Airport.
