NorthLink WA

Project description

NorthLink WA will provide a new transport link between Morley and Muchea, north of Perth. This project combines two adjacent Infrastructure Investment Program projects - the Central and Northern Sections (Swan Valley Bypass) and the Southern Section (Tonkin Highway Grade Separations).

The Central and Northern Sections involve the construction of a new 37km highway from the intersection of the Tonkin and Reid Highways in Malaga to the Great Northern Highway at Muchea. The Central Section will run from Reid Highway to Ellenbrook, and the Northern Section will continue on from Ellenbrook to Muchea. This new route will replace the Great Northern Highway as the main freight route through the Swan Valley.

The Southern Section involves upgrading the Tonkin Highway between Collier Road and Benara Road and construction of a single-point grade-separated interchange at Collier Road; construction of a grade-separated roundabout interchange at Morley Drive; and grade separation of the Benara Road intersection (with no connection to the Tonkin Highway).

Benefits

NorthLink WA will result in a better flow of traffic in the region, both on and off the new bypass route, boosting productivity and creating strong connections, with economic and social benefits. It will reduce travel times and congestion, and provide significant productivity benefits to the economy, industry, motorists and local communities.

In particular, the project will improve Western Australia's freight efficiency by introducing an alternative north-south freight route connection, relieving pressure on the Great Northern Highway through the Swan Valley.

This project will provide a continuous connection from the Perth International Airport area to Muchea on the Great Northern Highway.

Funding

The Australian Government is contributing $682.1 million from the Infrastructure Investment Program and $138.7 million from the GST revenue shortfall in 2014-15, for a $820.8 million contribution towards the $1.0 billion project.

Timetable

The project was completed in April 2020.
