The Tonkin Highway is a 45km north-south highway connecting Reid Highway to Thomas Road, Oakford. It connects the south-east corridor with the north-west and north-east corridors of the Perth metropolitan area.
The south-east corridor is an important and fast growing area faced with increased congestion, higher travel times for freight vehicles and reduced safety outcomes on the existing road network. Population projections show that by 2031, sustained growth in the south-east sub-region will increase by 35 per cent from the 2008 base level. This additional population will put significant pressure on the existing road network with volumes exceeding recommended capacity.
The project will extend the Tonkin Highway from Thomas Road to the South Western Highway including at grade separations at Thomas, Orton, and Mundijong Roads and South Western Highway and a grade separated interchange at Bishop Road.
The project will:
- improve freight efficiency, connectivity and travel time
- improve road safety and reduce congestion for all road users
The Australian Government has committed $404 million towards the $505 million project.
The project is in planning.
