Gateway WA now complete

The largest road project undertaken in Perth to date, the Gateway WA project, has been completed nearly a year ahead of schedule and under budget.

The project was delivered by an alliance consisting of CPB Contractors (formerly Leighton Contractors), Georgiou, GHD, AECOM and BG&E, together with Main Roads Western Australia.

Works on the momentous project included the construction and upgrade of five main interchanges, widening Tonkin Highway to six lanes between Great Eastern Highway and Roe Highway and upgrading Leach Highway between Tonkin Highway and Orrong Road to expressway standard.

The project incorporates road and bridge improvements, nearly 21 kilometres of shared path and local connections for pedestrians and cyclists, approximately seven kilometres of noise/screen walls, a major landscaping program and the use of Intelligent Transport System technology.

Gateway WA delivers a safer and more efficient transport network around Perth Airport and the industrial areas of Kewdale and Forrestfield.

The project was jointly funded through a $676 million investment from the Federal Government and $310 million from the Western Australian Government.
