Grand Junction, Hampstead and Briens Road Intersection Upgrade
About the project
The Australian and South Australian Governments are jointly funding the $19 million upgrade of the Grand Junction, Hampstead and Briens Road Intersection.
Grand Junction Road and Hampstead Road are key to freight movement and the existing single right turn lane at the intersection causes problems due to the slow acceleration of heavy vehicles. There is a need for additional capacity on all approaches to the intersection to allow for this movement by duplicating the existing right turn lane.
On average more than 58,400 vehicles travel through the intersection each day.
There have been 89 crashes at the intersection in the past five years, including 35 casualty crashes. Approximately 49% of all crashes were rear end crashes.
The upgrade will improve the safety of the intersection and will reduce congestion for motorists.
Early works are expected to commence in the third quarter of 2020, with main works expected to begin in early 2021, weather permitting.
The current proposed treatments for the intersection include:
- widening of Grand Junction Road (east side), with the extension of the right turn lane onto Briens Road travelling northbound, signalised left turn lane onto Hampstead Road travelling southbound, and three through lanes on Grand Junction Road;
- widening of Grand Junction Road (west side), with the installation of dual right turn lanes onto Hampstead Road travelling southbound and three through lanes on Grand Junction Road;
- widening of Briens Road to accommodate dual right turn lanes onto Grand Junction Road travelling westbound and signalised left turn lane onto Grand Junction Road travelling eastbound;
- widening of Hampstead Road, to accommodate the proposed treatments;
- upgraded pedestrian crossings within the intersection, including new pedestrian crossing lights and ramps;
- dedicated bicycle lanes on all approaches;
- pavement construction and surfacing; and
- new and upgraded traffic signals, road lighting, line marking, and drainage.

DPTI COVID-19 Response
To help safeguard the DPTI project team and the community, we have implemented measures to manage the risks of, and our response to, contracting COVID-19.
These include but are not limited to, increased personal hygiene practices and limiting face-to-face contact.
The project team will provide construction updates and work notifications via social media, letterbox drops, emails and the Project website. We are also available to speak via telephone (1300 794 880).
We encourage the community to register for email updates.
There will be no planned community events or information sessions until further notice.
Community and stakeholder engagement
Community and stakeholder engagement is important for the successful delivery of this project. As part of the project’s early concept design and review process, DPTI invited the community to provide their feedback on the proposed design of the intersection upgrade. This consultation concluded on 24 April 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 construction on the intersection upgrade is expected to commence early next year, with project completion expected in early 2022, weather permitting.
Service relocation works
As part of the project, service relocation works will be undertaken along Grand Junction Road, Hampstead Road and Briens Road to facilitate the intersection upgrade. These works will be undertaken in stages.
Works commenced on Wednesday, 24 June, with completion expected by the end of the year, weather permitting. The majority of works will be undertaken during the day, Monday to Friday, between 7am and 5pm, with some weekend works.
Intermittent night works may be required, between 7pm and 7am, in order to minimise traffic impacts and to ensure the works can be completed safely and efficiently.
Service relocation works will include, APA Gas works, relocation of SA Power Networks 66kV & 11kV infrastructure, SA Water asset alterations and the relocation of telecommunications infrastructure.
Some vegetation along the project corridor will be required 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.
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.
Major construction on the intersection upgrade is expected to commence early next year, with project completion expected in early 2022.
