Nairne Intersection Upgrade
The State Government will improve road safety and traffic efficiency through the construction of a four-way, single lane roundabout, realigning the Woodside Road and Saleyard Road T-junctions with Old Princes Highway at Nairne. This project is part of the Adelaide Hills Intersections Upgrade Initiative and is being delivered as an election commitment by the State Government.
The upgrade will seek to reduce delays for Woodside Road traffic, maintain a good level of intersection performance and cater for future growth. The upgrade will also aim to improve safety for pedestrian and cyclist movements in the area, particularly for Nairne Primary School students.
The intersection of Woodside Road and Old Princes Highway is located on the western outskirts of Nairne within a 50km/h speed zone. Since the completion of the Bald Hills Interchange project in 2016, traffic volumes at the Woodside Road and Old Princes Highway intersection have increased by approximately 10-15%.
Preliminary planning identified a four-way, single lane roundabout incorporating Saleyard Road as the preferred solution to address these project objectives.
- Construction of a four-way single lane roundabout, including realignment of the two T-junctions of Old Princes Highway with Saleyard Road and Old Princes Highway with Woodside Road
- 2.5 metre wide, New Shared Use for the extent of works.
- Provision of pedestrian fencing to encourage crossing at desirable locations only.
- Relocation of the pedestrian actuated crossing (push button) on the Old Princes Highway eastern approach approximately 70 metres east of the roundabout.
Other proposed treatments include:
- Upgraded LED road lighting for the extent of the works.
- Installation of new safety barrier (where required).
- Improved drainage, including new kerb and gutter.
- New asphalt surfacing and line marking.
Community Information Sessions
Thankyou to all those who attended our Community Information Sessions held in November 2019 and March 2020. Feedback provided has been considered in the design process.
Nairne - What’s next?
The design of the roundabout for the Woodside Road and Old Princes Highway intersection has been finalised. A contract for these works is likely to be awarded in mid-2021, with main construction works expected to commence in mid to late 2021, weather permitting.
Early works including property demolition and service relocations have commenced and are expected to be completed by mid 2021.
To help safeguard the community and DIT staff, we have implemented measures to manage the risks of, and our response to, COVID-19.
These measures include but are not limited to, increased hygiene practices and limiting face-to-face contact.
