Gateway WA is delivering 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 road project ever undertaken by Main Roads to date, working to improve the safety and efficiency of one of the State’s most important transport hubs.
The project involves 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 four new grade separated interchanges and the upgrade of a fifth interchange.
The project will form an iconic gateway to Perth that will create a lasting impression for road users, residents and visitors to Western Australia.
Project Milestones to Date
- The Abernethy Road on-ramp to Tonkin Highway southbound was opened in December 2013 which provides immediate relief to the freight industry by cutting 3.7km off the transport route to the regional network. The new on-ramp allows traffic direct access to Tonkin Highway (southbound) from Abernethy Road in Forrestfield.
- The realignment of the Gerry Archer Reserve was undertaken to accommodate the new Leach Highway / Abernethy Road interchange. This legacy project by Gateway WA involved close work with the City of Belmont and user groups of the reserve, and was completed in December 2013.
- A major step forward in the transformation of the Tonkin Highway / Horrie Miller Drive / Kewdale Road intersection into a grade separated interchange took place mid-2014 with the successful switch of several kilometres of four lane traffic onto a newly constructed, temporary intersection.
- The lifting and placement of 24 bridge beams took place in July 2014 to form the basis of the first of four bridges at the future Tonkin Highway / Leach Highway interchange.
- In August 2014 a major traffic switch took place at the Leach Highway / Abernethy Road intersection which has placed traffic onto a temporary alignment and allows the project team to progress work forming the future interchange.
- In December 2014 the first bridge on the Gateway WA project at the Leach Highway / Abernethy Road interchange opened to traffic.
- In early 2015 the upgrade to the Kewdale Industrial Precinct was completed ahead of schedule. This work involved a number of local road modifications to the precinct to support the upgrade of the regional road network.
- There were a number of major changes put in place for the travelling public at the Tonkin Highway / Horrie Miller Drive / Kewdale Road interchange earlier this year to enable the project team to progress the interchange to its ultimate arrangement. This has placed road users onto some finished parts of the interchange.
- In 2015 some movements were opened to traffic on Western Australia’s first single point urban interchange (SPUI) at Leach Highway / Abernethy Road. A guide to using the interchange is available on the Gateway WA website.
- The project’s landscaping team has commenced installing more than one million plants across the project site.
The full scope of works is expected to be completed by mid 2016, ahead of the planned consolidation of the domestic and international terminals at the Perth Airport.
The target dates for completion are as follows:
- Leach Highway / Abernethy Road Interchange – Late 2015
- Tonkin Highway / Leach Highway Interchange – Late 2015
- Tonkin Highway / Dunreath Drive Interchange – End 2015
- Tonkin Highway / Horrie Miller Drive / Kewdale Road Interchange – End 2015
- Tonkin Highway / Roe Highway Interchange upgrade – Mid 2016
