Cross Road and Fullarton Road Intersection Upgrade

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 Cross Road and Fullarton Road intersection is located approximately five kilometres south-east of Adelaide’s Central Business District (CBD), and is adjacent to the University of Adelaide Waite Campus and Urrbrae High School, within the suburbs of Urrbrae and Kingswood. 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 is a major traffic and freight route, connecting to export and import gateways and intermodal terminals. Fullarton Road forms part of the Inner Ring Route, which is a major traffic route. Both Cross Road and Fullarton Road are also high frequency public transport corridors.

An average of approximately 52,600 vehicles per day pass through this intersection (based on a count conducted in August 2019). The intersection is currently experiencing travel time delays in peak periods, resulting in inefficient, unreliable journeys and poses safety risks for all road users. During the last five year period (2015 to 2019) there have been 35 reported crashes for Cross Road/Fullarton Road Intersection, Urrbrae. Of these, there were two serious injury crashes resulting in three serious injuries; 14 minor injury crashes resulting in 14 minor injuries; and 19 property damage crashes.

Once complete, the upgrade will improve travel times and safety for all road users, improve network reliability and support economic activity.

Early works commenced in July 2021, with major construction scheduled to commence late 2021. Project completion is expected 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.

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.

Design Development: key considerations

Key considerations for design development include:

  • stakeholder and community input and consideration of the needs of the local university, schools, residents and businesses including safe access, car parking 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; and
  • consideration of environmental aspects including surrounding vegetation and heritage aspects.

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.

Consultation on this concept design commenced 3 December, 2020 and concluded 14 June, 2021.

During this period:

  • the Department held two community information sessions to meet the community and seek feedback;
  • there was also an opportunity for the community to provide feedback via phone, email, website feedback form, social pinpoint comments and hard copy feedback forms collected at the two community information sessions;
  • information about the proposed design was sent to over 4 900 local households, businesses and those who signed up for project updates; and
  • approximately 95 people attended over the two community information sessions

What we heard during the recent consultation period

The key themes raised were:

  • the Urrbrae Gatehouse
  • environmental impacts
  • heavy vehicle traffic
  • construction impacts
  • public transport and bus stops
  • safety
  • traffic
  • cycling infrastructure
  • access
  • pedestrian considerations
  • property impacts
  • stormwater
  • street parking
  • left turn and right turn movements
  • stakeholder and community input.

Design update

The key changes being made to the design in response to community feedback include:

  • wider footpaths for pedestrian movements;
  • additional indented bus bay on Fullarton Road;
  • reduced impacts to vegetation;
  • updates to the stormwater design; and
  • improved access into and out of Urrbrae Agricultural High School, including allowance for a right turn into the car park for southbound traffic and a left in/left out turn for northbound traffic.

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.

What's next?

Further information, including an updated design, will be provided to the community in the coming months. We will continue to engage with the community to inform the detailed designs for the project and throughout its delivery.

Early works update

Demolition works are underway to facilitate the intersection upgrade. These works are expected to be completed in early 2022, weather permitting.

Utility services relocation works

Early service relocation works are planned to commence from Monday, 27 September 2021, with completion in April 2022, weather permitting.

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.

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.
