NorthLink WA

NorthLink WA is a road construction project in Perth, Western Australia, that will see both the northern section of Tonkin Highway upgraded, and the road extended northwards as the Swan Valley Bypass, to bypass Great Northern Highway. These two component projects are separately funded, with both the state and federal governments contributing to each project. Construction is expected to begin in 2016, and be completed by 2019.

The proposed Perth Darwin National Highway (PDNH) Swan Valley Bypass is a planned new highway to bypass Great Northern Highway within Perth. From the junction of Reid Highway and Tonkin Highway at Malaga, it will head north towards Ellenbrook, and continue on to Great Northern Highway and Brand Highway in Muchea. The previously planned route of the PDNH, prior to 2012, followed Lord Street, east of Whiteman Park. The state and federal governments have allocated funding to the project, with construction scheduled to start in 2016.

The new road will have grade separated interchanges at:

• Reid Highway and Tonkin Highway at the Malaga – Noranda – Beechboro – Bennett Springs quadripoint
• Hepburn Avenue at the Ballajura–Cullacabardee–Whiteman tripoint
• Gnangara Road, Lexia
• The Promenade, Ellenbrook
• Neaves Road, Bullsbrook

Future interchanges, unfunded as of 2015, include:

• Stock Road, Bullsbrook
• Great Northern Highway and Brand Highway, Muchea

Tonkin Highway upgrade

The federal government has allocated $140.6 million to grade-separate Tonkin Highway's intersections with Benara Road, Morley Drive and Collier Road. The funding is part of the five-year phase of the Nation Building Program from 2014–15 to 2018–19. The upgrades are intended to improve freight transportation along the highway. The total cost is expected to be $281.2 million. In the lead up to the 2013 Australian federal election, which resulted in a change a government, the Labor candidate for Perth, Alannah MacTiernan, accused the then-opposition's candidate of lying to the electorate over their commitment to the upgrade. The official policy costings did not contain specific funding for the project. However, an opposition spokesperson claimed it was "in the current forward estimates", and not in the costing, as the upgrade was neither a "new and accelerated" project, nor a project that would definitely not be funded.
