Portrush and Magill Road Intersection Upgrade

About the project

The Australian and South Australian Governments have announced $98 million joint funding for the upgrade of the Magill and Portrush Roads intersection, with the cost shared equally.

The Australian Government commitment is part of the Commonwealth Urban Congestion Fund. The State Government’s contribution addresses recommendations of the State Government’s Keeping Metro Traffic Moving Report. The report identifies this intersection as a priority location for treatments that address road congestion and keep traffic flowing

The intersection of Portrush Road and Magill Road is part of the National Land Transport Network and forms part of the Outer Ring Route, which is a major traffic route and freight route.  Both Portrush and Magill Roads are also high frequency public transport corridors.

The upgrade will:

  • improve travel times
  • improve safety for all users
  • improve network reliability
  • improve economic productivity.

Early works commenced in June 2020, with major construction commencing in April 2021.

COVID-19 Response

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

Face-to-face engagement opportunities may be restricted and we will continue to be guided by the advice of health authorities, with the health and safety of our stakeholders always our highest priority.

Engagement with community and industry is crucial and we will facilitate information sessions as much as possible to enable face to face engagement.  It is important to assist in managing these events that you register as requested to enable physical distancing as much as possible.

What's next?

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 held two information sessions in February to meet members of the community and seek feedback.

Feedback on the draft concept design was also available until 18 March 2020.

All feedback received from the community is being reviewed and considered by the Project Team. Receiving feedback from the community is important and will continue to help inform the development of the design.

Major works commence

As part of the project, the Department has undertaken property demolition, service relocations and early investigation works along Portrush Road and Magill Road to facilitate the new intersection upgrade. These early works are nearing completion and major works on the intersection are due to commence in early April 2021, with project completion expected in 2022.

The majority of the works will be undertaken Monday to Saturday, between 7am and 6pm.

Speed restrictions will be in place during the works, and lane restrictions will be implemented intermittently to maintain the safety of road users and workers. Night works will be required on several occasions during major construction, and are expected to commence in April 2021 (see below for upcoming night works).

Night works

Works including the removal of existing traffic islands, and the installation of Common Service Trench (CST), will be undertaken at night.

In order to minimise the impact to road users and ensure these works can be completed safely and efficiently, works will be undertaken between 7pm and 6am from Tuesday, 6 April 2021, until Friday, 23 April 2021, weather permitting.

Every effort made to minimise impacts to surrounding properties and road users, as much as practically possible.

For further information regarding these works, download a copy of the latest notification.

An updated intersection concept plan, which also shows the proposed vegetation and landscaping for the project, is now available to download here.

Continuing works

As part of the project, service relocations and additional investigative works are being undertaken along Portrush Road and Magill Road to facilitate the new intersection upgrade, with works being undertaken in stages.

Demolition works: Demolition works commenced in late June. Works are being undertaken each day, Monday to Saturday, between 7am and 5pm. Some works may also be required on Sundays between 9am and 5pm, however this will only occur if necessary.

For further information about these works, download a copy of the notification and fact sheet.

Speed and lane restrictions will be in place in the vicinity of the works, however the intersection will remain open to traffic at all times. Please take extra care when workers are on site. Observe speed limits, lane restrictions and traffic controllers when travelling through the area.

Every effort will be made to minimise impacts to surrounding properties and road users, as much as practically possible. Access for properties will be maintained.

Pedestrians and cyclists are advised to take care when travelling through the area. For safety reasons there may be some restricted access at various times. Where required signage will be in place to direct pedestrians and cyclists to alternative access and/or detours.

Noise Assessment and Security

A noise assessment will be undertaken during the detailed design phase of the project in accordance with DIT’s Noise Traffic Guidelines https://www.dit.sa.gov.au/standards/environment and consideration will be given to the use of treatments for noise sensitive properties. Noise from construction activities will be managed through a Construction Environmental Management Plan which will establish the mitigation measures and consultation requirements for different construction activities.  The security of adjoining properties during demolition of buildings and structure, during construction and on completion of the project will also be addressed.

The department is continuing to liaise with the community as the detailed design is developed. All feedback and concerns will be considered as the project team continue through the design process to identify a solution that balances the needs of the project’s various stakeholders.
