About the project

The Australian and South Australian Governments have jointly (50:50) committed $61 million to upgrade the Cross Road and Fullarton Road intersection. The project is expected to support approximately 65 jobs per year, averaged over the life of the construction period.

The Australian Government’s commitment is part of the Commonwealth Urban Congestion Fund. The State Government’s commitment was announced as part of the 2019-2020 State Budget, to bust congestion by upgrading a number of Metropolitan intersections. The State Government’s contribution addresses recommendations of the 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 project design has progressed to 70% and a Design and Construction contract has been awarded to Fulton Hogan. A site compound has been established on the corner of Fullarton Road and Euston Avenue, Highgate. This facility will be used by the project team for the duration of works.

Major works for the project are expected to commence in mid March 2022. Once complete, the upgrade will improve travel times and safety for all road users, improve network reliability and support economic activity.

Construction on this upgrade has now begun. The new intersection is expected to be opened to traffic in late 2022, weather permitting.

Concept design

The current proposed concept design has been further developed based on the significant feedback received from the community during the planning phase of the project, as well as ongoing consultation with key project stakeholders.

Extensive community and stakeholder consultation will continue throughout the early design and delivery phases of the intersection upgrade.

Please note this image is an artist’s impression for illustrative purposes only, and not a final design.

For further detail download a copy of the current concept plan.

The proposed treatments include:

  • widening of Cross Road, with the installation of dedicated right turn lane into Fullarton Road on both approaches, three through lanes on both approaches, a dedicated left turn slip lane onto Fullarton Road (northbound) and dual left turn lanes onto Fullarton Road (southbound);
  • widening of Fullarton Road, with the installation of dedicated right turn lanes into Cross Road on both approaches, three through lanes on both approaches, a dedicated left turn slip lane onto Cross Road (westbound) and a shared though and left turn lane onto Cross Road (eastbound);
  • indenting of Urrbrae Agricultural High School Bus stops on the south side of Cross Road (west) and bus stop 12 on the west side of Fullarton Road (north), and relocation of bus stops 165 located on the north and south sides of Cross Road;
  • upgraded pedestrian crossings within the intersection, including ramps, dedicated on-road bicycle lanes on all approach exit lanes to/from the intersection;
  • a seagull median treatment on Fullarton Road for access to Urrbrae Agricultural High School;
  • pavement construction and surfacing;
  • new and upgraded traffic signals;
  • LED road lighting for the extent of the works; and
  • new line marking and drainage.

Community Engagement

In December 2020, the Department for Infrastructure and Transport (the Department) released the proposed concept design for the project. This design was developed in response to the feedback received from the community during the 2019-2020 planning phase of consultation.

In addition, the South Australian government has come to an agreement with the University of Adelaide to find a solution for the future of the Urrbrae Gatehouse, with the structure to be decommissioned, rebuilt and repurposed. This will include relocating the Gatehouse to a new site on Claremont Avenue, Urrbrae. Learn more Information about the Decommissioning of the Urrbrae Gatehouse

What's next?

The majority of works will be undertaken Monday to Friday, between 7am and 5pm, with some weekend works.

In order to minimise traffic impacts and to ensure the works can be completed safely and efficiently, some night works may also be required. Advance notice will be provided as works progress.

Works will include the relocation of some SA Power Networks and telecommunications infrastructure.

Some vegetation will also need to be removed to facilitate these works. Prior to any removals, the work area will be inspected on site by a suitably qualified flora and fauna specialist and where required, fauna will be relocated to a similar habitat. Impacts will be minimised, as much as practically possible.

COVID-19 Response

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

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.
