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. The upgrade is expected to support approximately 16 full time equivalent jobs per year, over the life of the project.

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 81,600 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 27 casualty crashes.

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

Major construction works for the intersection upgrade commenced in late January 2021, with project completion expected in mid-2021, weather permitting.

The current proposed treatments for the intersection upgrade include:

  • 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.

DIT COVID-19 Response

The Department will continue to tailor community engagement opportunities in line with the latest COVID-19 advice from health authorities.

We encourage the community to register for email updates.

Community and stakeholder consultation

Community and stakeholder consultation is important for the successful delivery of this project. As part of the project’s early concept design and review process, DIT invited the community to provide their feedback on the proposed design of the intersection upgrade. This consultation concluded on 20 March.

Receiving feedback from the community is important and will continue to help inform the development of the design.

What’s next?

Construction  Commencement

Major works for the project commenced late January 2021.

Night works

Night works for the laying of new asphalt and the final wearing surface are being undertaken in stages.

Hours of work are between 7pm and 6am, Sunday to Friday. No works will be undertaken on Saturday nights.

Some noise disturbance can be expected at times while these works are completed. However, every effort will be made to minimise disruption to surrounding properties and road users, as much as practically possible. Access to properties during these works will be maintained.

To safety facilitate these works, changed traffic conditions will be in place as outlined in the latest night works notification and attached maps. Speed and lane restrictions, road closures and detours will be in place.

**Night works will restart tonight on this project to ensure these essential works can be delivered for the safety and benefit of the South Australian community. Works will continue on stage 5 for approximately 6 nights, with stage 6 works anticipated to commence on Monday, 2 August 2021, weather permitting.**

Stage 5: Main North Road, northbound traffic restrictions

Continuing Monday, 26 July 2021 for approximately 6 nights, weather permitting.

Night works will be undertaken to lay the final layer of asphalt on the northbound lanes of Main North Road, from Freda Thompson Place, to immediately south of the intersection. The following traffic arrangements will be in place:

  • The northbound lanes in this location will be closed, access will be maintained in both directions along the southbound lanes.
  • Freda Thompson Place will be closed at its intersection with Main North Road. Access to the Parafield business area will be via Kesters Road and Kings Road
  • Bus stops 40 and 41 on Main North Road (northbound) will be closed during works. Notices will be placed on bus stops to inform passengers of changes.
  • Heavy vehicle detours will also be in place.
  • All turning movements for passenger vehicles will be maintained at the Main North Road, McIntyre and Kings Roads intersection with lane closures in place.

Stage 6: Main North Road, southbound traffic restrictions

Commencing Monday, 2 August 2021 for approximately 6 nights, weather permitting.

Night works will be undertaken to lay the final layer of asphalt on the southbound lanes of Main North Road, from Beafield Road, to immediately south of the intersection. The following traffic arrangements will be in place:

  • The southbound lanes in this location will be closed, however access will be maintained in both directions along the northbound lanes.
  • Southbound access to the Main North Road service road will be closed from Main North Road. Access to the service road will be via McIntyre Road, Peacock Road and Ayfield Road or Kesters Road.
  • Bus stop 40 and 41 on Main North Road (southbound) will be closed during works. Notices will be placed on bus stops to inform passengers of these changes.
  • All movements will be maintained at the Main North Road, McIntyre and Kings Roads intersection, with lane closures in place.
