Cross Road and Fullarton Road Intersection Upgrade

About the project

The Australian and South Australian Governments have announced $61 million joint funding for the upgrade of the Cross Road and Fullarton Road Intersection, with costs to be 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.

Cross Road and Fullarton Road are both important commuter routes, serving traffic to and from the Mitcham Hills area and the South Eastern Freeway.

Cross Road forms part of Adelaide’s Outer Ring Route (ORR) which plays a key role in moving Adelaide traffic efficiently and safely. The ORR is also a key freight route connecting to export and import gateways and intermodal terminals.

Approximately 53,000 vehicles travel through the Cross and Fullarton Roads intersection each day and it currently experiences travel time delays in peak periods.

Historical crash data indicates 44 crashes recorded between 2013 and 2017, of which there were 19 casualty crashes.

The upgrade will:

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

Early works are planned to start in 2020.

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.

Planning study and design development: key considerations

Key considerations for the planning study and design development will include:

  • stakeholder and community input and consideration of the needs of the local university, schools, residents and businesses including safe access, carparking and managing construction impacts
  • road widening to improve safety and capacity of the intersection
  • right hand turning solutions at the intersection
  • improving travel times to reduce congestion
  • provision of safer pedestrian crossings
  • consideration of bus stops and active transport opportunities
  • consideration of environmental aspects including surrounding vegetation and heritage aspects.

The contract for the planning study and design development has been awarded to the Cross Roads Team, comprising Jacobs Group (Australia) Pty. Ltd. in partnership with WSP (Australia).

It is anticipated that this detailed planning and design work will conclude in 2020.

Community and stakeholder engagement forms an important part of the planning process. The department, together with the Cross Roads Team will engage with residents, land owners, business owners and other stakeholders as the preferred option is developed.  We encourage you to have your say while the planning process is underway (see our contact details below).

Online survey now closed

Thank you to everyone that completed a survey and provided feedback to illustrate how you use the intersection, your experience with traffic congestion, access, active transport, safety and public transport. The information gathered from this survey will help inform the concept design.

Concept Design

The Concept Design is still under development.  Once finalised, the Concept Design will be made publicly available for comment and the community will be notified.

Further Investigations

We have heard the level of community concern about the retention of heritage in the area, particularly in relation to the State Heritage Listed Waite Arboretum and Urrbrae House Gatehouse (or ‘Lodge’).

DIT is conducting further investigations to inform the development of a preferred concept design. This will include more detailed surveys and investigations on heritage and vegetation.

In the coming weeks, there will be activity and personnel conducting surveys in the area.

Please note that these are investigations only. They are being conducted to look at options to mitigate heritage and vegetation impacts as much as possible.

The Department continues to work with the University of Adelaide, Heritage SA and other key stakeholders to deliver the best outcome for the project and community on this project.

Meanwhile we welcome you to get in touch with us with your queries or feedback.

Site Investigation Works

In order to progress with design development, site investigation works will be undertaken in the vicinity of the intersection. Works are expected to commence on Wednesday 16 September and be complete by early October, weather permitting. Works will include:

  •  Location of underground services, and
  •  Geotechnical drilling.

Drilling works will be undertaken during the day, between the hours of 10am and 3pm. While some noise can be expected during drilling works, effort will be made to minimise the disturbance.

Glen Osmond Road and Fullarton Road will remain open during works, however temporary lane and speed restrictions may be required when workers are on site.

Please take extra care when workers are on site. Observe traffic management signs, speed limits, lane restrictions and traffic controllers when travelling through the area.
