The extension of Western Australia’s Tonkin Highway to South Western Highway is another step closer, with an Expression of Interest just released for contractors to tender for the project.
The $1 billion investment will see Tonkin Highway extended 14 kilometres south to South Western Highway, as well as upgrades to Thomas Road.
The surrounding roads will be connected to Tonkin Highway with grade separated interchanges at Thomas Road and Bishop Road, and roundabouts at Orton Road, Mundijong Road and South Western Highway.
Underpasses will be provided at Abernethy Road and Shanley Road, and a bridge over Wright Road.
Thomas Road will be duplicated from Kargotich Road to Wungong South Road to address traffic congestion, improve road safety and cater for the growing population east, north and south of Byford.
“This long-awaited southern extension of Tonkin Highway represents the largest investment this corridor has ever seen, and has been planned for several years, to ensure the project delivers maximum benefits for road users and the broader community,” said WA Minister for Transport, Rita Saffioti.
“Extending Tonkin Highway will improve efficiency of truck movements and ensure heavy vehicles are diverted away from growing residential areas like Byford.
“This will enhance safety and improve the amenity of local communities.”
The project forms part of a package of infrastructure works set to transform the Tonkin Highway corridor, providing a high standard north-south transport link from Muchea down to Mundijong.
“These include the upgrade between Collier Road and Great Eastern Highway – known as the Tonkin Highway Gap, the upgrade of the intersections south of Roe Highway at Hale, Welshpool and Kelvin roads and the Tonkin Highway – North Ellenbrook Interchange project,” said Federal Minister for Infrastructure, Transport, Regional Development and Local Government, Catherine King.
It will also complement the nearby METRONET Byford Rail Extension, METRONET Thomas Road Over Rail and Thomas Road Safety Improvements between Kwinana Freeway and South Western Highway to provide communities in the south with greater access to the state’s transport network.
