Main North Road, Kings and McIntyre Roads Intersection Upgrade

About the project

The Australian and South Australian Governments have committed $13 million in joint funding to upgrade the Main North Road, Kings and McIntyre Roads Intersection.

Main North Road is a major traffic and freight route that connects the northern parts of metropolitan Adelaide with Adelaide’s Central Business District. The current intersection is operating at capacity in peak periods, with signal phasing and traffic lanes fully utilised, creating congestion.

On average, more than 81 550 vehicles travel through the intersection each day. Increased development in the immediate vicinity will further increase the use of the intersection.

There have been 77 crashes in the past five years, including 26 casualty crashes.

The Department of Planning, Transport and Infrastructure will be upgrading the intersection to improve safety and travel time for motorists.

Early works expected to commence in the second quarter of 2020, with major construction expected to commence in late 2020.

The current proposed treatments for the intersection upgrade include:

  • widening of Main North Road, with the installation of an additional right turn lane into Kings Road, and three through lanes heading south on Main North Road;
  • widening of Main North Road, with the installation of an additional right turn lane into McIntyre Road, and three through lanes heading north on Main North Road;
  • installation of additional through lane on Main North Road between Freda Thompson Place and Kings Road (north-east bound);
  • installation of additional through lane on Main North Road between McIntyre Road and Kesters Road (south-west bound);
  • extension of dual right turn lanes heading north-east from McIntyre Road onto Main North Road Road;
  • separation of left turn traffic from Main North Road onto Kings Road and left turn traffic from Kings Road onto Lawrence Hargrave Way;
  • new and upgraded pedestrian ramps and footpaths around the intersection;
  • dedicated bicycle lanes on both approaches of Main North Road; and
  • new and upgraded traffic signals, road lighting, line marking, and drainage.

Community and stakeholder consultation

Community and stakeholder consultation is important for the successful delivery of this project. We are seeking your feedback on the proposed design of the intersection upgrade.

A concept plan for the upgrade has been prepared and we are inviting the community and stakeholders to provide feedback. Your feedback will be provided to the project team for review and consideration and will help inform the detailed design.

We encourage you to provide feedback via the projects Registration, Feedback and Suggestion page, by emailing or by calling 1300 794 880. Feedback can be provided up to and including Friday, 20 March 2020.

Early site investigation works

As part of the early design process, works to identify the location and depth of all utility services in the vicinity of the proposed upgrade will occur throughout February and early March.

These works will be undertaken during the day, Monday to Friday, between the hours of 9am and 4pm and will take approximately four weeks to complete, weather permitting.

Speed and lane restrictions will be in place in the vicinity of the works from 10am to 3pm daily, however the road will remain open to traffic at all times. Access for properties, pedestrians and cyclists will also be maintained and every effort will be made to minimise impacts to surrounding properties and road users where possible.

The data collected from these investigations will help inform the projects detailed design.
