Northern Connector Project

Project Overview

The $867 million Northern Connector is open to traffic. The six-lane, 15.5 kilometre motorway now provides a vital freight and commuter link between the Northern Expressway, South Road Superway and Port River Expressway.

This project has focused on delivering economic benefits to the local South Australian community including creating 480 full-time equivalent jobs each year during construction.

  • At least 50% of all jobs to be filled by northern suburbs residents.
  • At least 90% of on-site labour hours to be undertaken by South Australians.
  • At least 20% of all on-site labour hours to be undertaken by ex-automotive industry workers, Aboriginal people, people facing barriers to employment and trainees and apprentices.

The Australian Government has committed $694 million to the project, with $173 million from the South Australian Government.

DPTI COVID-19 Response

To help safeguard the Northern Connector project team and the wider community, we have implemented measures to manage the risks of, and our response to, contracting COVID-19.

These include but are not limited to, increased personal hygiene practices and limiting face-to-face contact.

The Northern Connector project team will provide construction updates and work notifications via letterbox drops, emails and the project website. We are also available to speak via telephone.

We encourage the community to register for email updates by emailing

There will be no planned community events or information sessions until further notice.

The Northern Connector opened to traffic from Saturday, 7 March.

The six lane motorway posted speed limit has now been increased between the Southern and Northern interchanges from the temporary 80km/h limit to the motorway’s permanent maximum speed of 110 km/h.

Finishing works will continue which may require some lane and speed restrictions, to ensure the safety of motorists and workers. Please keep an eye on our Facebook page and this website for further project updates.

On behalf of the project we would like to thank you for your patience and for your interest in the project.

A highlight of the day was the availability of free guided bus tours which drove along the new motorway to the Southern Interchange and back, with around 1,400 people enjoying these tours. People were also able to walk on a short section of the new road and drove on it to exit the site.

Other offerings during the day included virtual reality tours, children's activities and construction equipment displays, plus a free sausage sizzle with almost 6,000 snags cooked!
