Glen Osmond Road and Fullarton Road Intersection Upgrade
About the project
The Australian and South Australian Governments have jointly committed $35 million to upgrade the Glen Osmond Road and Fullarton Road intersection. The project is expected to support approximately 50 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 South Australian 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. This initiative maximises the use of current infrastructure through short to medium term improvements to the network.
The intersection of Glen Osmond Road and Fullarton Road, located approximately three kilometres south of Adelaide’s Central Business District (CBD), plays a vital role in moving people and goods from suburbs in the Mitcham Hills, the South Eastern Freeway and suburbs in the vicinity of Unley Road, Belair Road and Portrush Road to Adelaide City and the Inner Ring Route. Both Glen Osmond Road and Fullarton Road are key major traffic routes, primary freight routes and priority public transport corridors.
Glen Osmond Road and Fullarton Road are major traffic routes and primary freight routes linking commuters, businesses and freight to key activity centres. Fullarton Road forms part of the Inner Ring Route, which is a major traffic route. The intersection is also an integral component of Adelaide’s Public Transport corridor connecting users from the south-eastern suburbs of Adelaide to the CBD.
An average of approximately 58,000 vehicles per day pass through this intersection (based on a count conducted in September 2019). The intersection is experiencing heavy congestion, with competing traffic movements and network constraints leading to increased travel times and risks to safety.
The existing through lanes on Fullarton Road are causing problems due to inadequate capacity, resulting in long delays during peak periods. There is also a need for additional right turn capacity from Glen Osmond Road onto Fullarton Road.
Once complete, the upgrade will improve travel times and road safety, increase intersection capacity and enhance network reliability.
During the five year period between 2015 and 2019, at the intersection of Glen Osmond Road and Fullarton Road, there were 40 reported crashes at the intersection, consisting of eight minor injury crashes and 32 property damage crashes
Project design work will continue in the coming months with early works anticipated to commence by early-2021. Major construction works are scheduled to commence in 2021, with project completion expected in mid-2022, weather permitting.
The current proposed concept design has been 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.
The current proposed concept design (below) is now ready for public comment.
Extensive community and stakeholder consultation will continue throughout the early design and delivery phases of the intersection upgrade.
Please note, this is an artist's impression for illustrative purposes only and not a final design.

The proposed treatments for the Glen Osmond Road and Fullarton Road Intersection Upgrade include:
- widening of Fullarton Road to provide an additional (third) dedicated through traffic lane on each side of Fullarton Road through the intersection;
- widening on Glen Osmond Road to provide an additional (second) dedicated right turn lane from Glen Osmond Road onto Fullarton Road for traffic travelling northbound, and a longer right turn lane on Glen Osmond Road for traffic turning onto Fullarton Road to travel southbound;
- relocating and indenting Bus Stop 5 on Glen Osmond Road east of the intersection;
- removal of the right turn lanes on Fullarton Road travelling into Glen Osmond Road (right turn movements to be prohibited at all times);
- A sheltered right turn lane will be provided on Fullarton Road at the junction with Campbell Road. This will provide an alternate route for vehicles travelling south along Fullarton Road wanting to access the Arkaba Medical Centre via Campbell Road and Collins Street;
- installation of a pedestrian refuge on Fullarton Road between Gladstone Street and Campbell Road;
- realignment of Main Avenue to relocate the junction at Glen Osmond Road approximately 35 to 40 metres south-east from its current location, which will incorporate a sheltered lane for vehicles turning right from Glen Osmond Road;
- 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
- 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. For further information on the project please visit the Frequently Asked Questions (FAQ’s) page.

A concept design has been developed for the upgrade, taking into consideration feedback received from local residents and businesses in the first stage of consultation for the project.
The concept design is now available for public comment and has been developed to encompass project objectives, design criteria, community and stakeholder feedback to date and the outcomes of environmental, social, safety, economic and preliminary site investigations.
To provide feedback, register for project updates or to speak with a member of the project team, please see Further Information contact details below.
A project information session also will be held in mid-2021, the consultation period for feedback on the concept designs is ongoing.
All feedback received from the community will be reviewed and considered by the project team.
Community and stakeholder engagement forms an important part of the planning, design and delivery process. The Department will continue to engage with residents, land owners, business owners and other stakeholders as the preferred design is developed.
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.
