Construction Update May 2026
The City of Mitcham is currently undertaking Black Spot Program safety upgrade works at the intersection of Winston Avenue and Caulfield Avenue, Cumberland Park aimed at reducing vehicle speeds and improving road safety for motorists, pedestrians and cyclists.
Traffic detours and access arrangements are currently in place and are limited to the immediate area around the Winston Avenue and Caulfield Avenue intersection. Nearby streets are being used to detour drivers safely around the works, with traffic able to return to Winston Avenue as smoothly and efficiently as possible.
Pedestrian access to shops at the intersection has been maintained throughout the works, so customers can continue to visit as usual. Bus services have also been temporarily adjusted to ensure they can return to Winston Avenue in the quickest and safest way possible. To help support safe travel along detour routes, temporary 40 km/h speed limits have been introduced in nearby streets for the duration of construction.
Council is continuing to liaise with businesses located at the intersection and is closely monitoring conditions on site.
The raised intersection is expected to re-open to traffic by early July 2026, subject to weather conditions.
For more information regarding road closures and detour information please view the Intersection Closure and Detour Information tab to the right.
What works are being undertaken?
The scope of works includes:
Raised Intersection
A raised platform will be constructed through the intersection to slow traffic and improve safety. New road surfacing will be installed to tie into the existing road, along with high visibility treatments to clearly define the raised area for motorists.
Kerb and Road Works
Sections of existing kerb and road pavement will be removed where required and replaced with new kerb and drainage to improve stormwater flow. Pram ramps will also be upgraded to improve accessibility for pedestrians, wheelchair users and people with prams.
Footpath Improvements
Affected footpaths will be reinstated and new paved areas will be installed to suit the upgraded intersection layout.
Car Parking Adjustments
On-street parking spaces near the intersection will be adjusted where required, and new line marking will be installed to suit the updated road configuration.
LED Give Way Signs
Illuminated Give Way signs will be installed to improve driver awareness and enhance intersection safety. Underground electrical works will be undertaken to provide power to the signs.
Line Marking and Signage
Existing line marking will be removed where necessary and replaced with new line marking to reflect the upgraded design. Any affected traffic signage will be reinstated.
Landscaping Works
A new garden bed will be created within the road area, including installation of irrigation infrastructure. One existing tree will be relocated within the site, and new soil and mulch will be placed to complete the landscaped area.
Update - Detailed Design
The detailed design for the Winston Avenue and Caulfield Avenue intersection is now 90% complete pending minor stormwater design changes. You can view the design in the Concept Design tab to the right of this page. Residents and business owners near the intersection will receive further correspondence from Council before construction commences.
Thank you to those who provided feedback on the design for the Winston Avenue and Caulfield Avenue Intersection Upgrade.
116 contributions were received and the outcomes of our consultation are summarised to the right of this page in the Consultation Report.
To summarise the key themes in order of most mentioned:
- Suggestion to restrict right turn from Caulfield Avenue
- Support for the overall design
- Opposition to a 40km/hr speed limit
- Suggestion to maintain stop sign controls
- Suggestion to restrict additional car parking to improve visibility
- Opposition to the raised intersection
- Suggestion to install a roundabout
Each of these have been reviewed by our Traffic and Transport team with more detail provided in our Consultation report.
Of note is that Council is now seeking approval from the Department for Infrastructure and Transport to install flashing LED "Give Way" signs to enhance visibility and compliance at the Caulfield Avenue approaches to the intersection. This is similar to what has been approved for the Tutt Avenue and Rugby Street intersection upgrade, involving sensors to detect approaching vehicles.
If you have any further questions please do not hesitate to contact our Traffic and Transport team via 1300 133 466 or email yoursay@mitchamcouncil.sa.gov.au
Background
In late 2023, community engagement was conducted as part of a local area traffic management (LATM) study for the area bounded by Cross Road, Winston Avenue, Daws Road, and Goodwood Road with an aim to gather feedback from local residents, commuters and other interested parties to inform the development of traffic management interventions.
One of the key recommendations that emerged from this community engagement was an upgrade of the Winston Avenue and Caulfield Avenue intersection, which was identified as a black spot. The City of Mitcham nominated this project as part of the 2024-25 Black Spot Program and we are pleased to share that this nomination was successful. This includes funding of $407,830 (including GST) funded by the Department of Infrastructure, Transport, Regional Development, Communications and the Arts.
We are now seeking community feedback on the design for the Winston Avenue and Caulfield Avenue intersection upgrade. Other interventions proposed as part of the LATM study will be subject to separate community consultation as required.
What does this upgrade hope to achieve?
The project aims to achieve significant road safety improvements for vulnerable road users and motorists through the;
- Implementation of a raised intersection treatment aimed at naturally reducing vehicle speeds, creating a safer environment for vehicles and pedestrians.
- Introduction of multi-block paver threshold treatments and raised side intersections intended to strengthen the effectiveness of existing priority controlled 'Give Way' signs by providing additional visual cues to road users.
- Installation of kerb extensions designed to enhance intersection visibility, making navigation safer and more efficient.
- Modification of speed limit to 40km/h proposed for Winston Avenue subject to outcome of the Department of Infrastructure and Transport (DIT) South Road traffic study and the Council LATM study.
