Adelaide Hills Intersections Upgrade Initiative
About the initiative
The Adelaide Hills Intersections Upgrade features two locations:
- Woodside Road and Old Princes Highway intersection, Nairne; and
- Onkaparinga Valley Road, Tiers Road and Nairne Road intersection, Woodside.
Woodside Road and Old Princes Highway intersection, Nairne
The State Government will improve road safety and traffic efficiency through the upgrade of the Woodside Road intersection with Old Princes Highway at Nairne.
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.
Nairne Community Information Sessions
Community Information Sessions were held in Nairne in November and the planning study team also doorknocked local residences to talk about the project. More than 100 people came along to meet with the planning study team, hear project details, ask questions, and provide feedback.
In March, the Department held another Community Information Session to present the community with the preferred design.
Thank you to everyone that attended.
The Nairne planning study team has undertaken ongoing engagement with local residents through doorknocking and other forms of contact to update them on planning study and listen to their concerns. The planning study team also met with the Nairne District and Residents Association.
Nairne- What’s next?
It is anticipated that the study at Nairne will be completed in mid-2020.
Onkaparinga Valley Road, Tiers Road and Nairne Road intersection, Woodside
The Australian Government has committed $2 million within its Roads of Strategic Importance program, over the 2019-20 to 2022-23 period, towards improving freight productivity and efficiency through the upgrade of the Onkaparinga Valley Road, Tiers Road and Nairne Road intersection.
The upgrade will seek to improve intersection safety and operation, balancing local community and industry requirements, and cater for future growth.
The intersection of Onkaparinga Valley Road, Tiers Road and Nairne Road forms a staggered-T arrangement and is located within a 50km/h speed zone in the Woodside township. Onkaparinga Valley Road carries around 10,500 vehicles per day to the north of the intersection and 8,500 vehicles per day to the south of the intersection. Nairne Road carries approximately 4000 vehicles per day.
A Planning Study for the proposed intersection upgrade is underway and community and stakeholder engagement forms an important part of the study. As planning progresses further consultation with landowners, businesses and residents will occur to help inform the preferred concept and design.
Woodside Community Information Sessions
In December, Community Information Sessions were held in Woodside. The planning study team doorknocked and met with around 30 businesses adjacent the intersection, and provided displays advertising the event in several public spaces around Woodside.
Around 60 people attended the community session to speak to the planning study team, hear project details, ask questions, and provide feedback. Thank you to everyone that attended.
A note to the Woodside community
Following our Community Information Sessions in December 2019, our intent was to engage further with community on the intersection upgrade in early 2020.
The tragic Cudlee Creek fire then occurred and changed priorities. In consultation with the Adelaide Hills Council (AHC), a decision was made to postpone direct engagement with the community until after the immediate bushfire recovery period.
To help safeguard the DIT planning study team and the community, 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.
The Adelaide Hills Intersection Upgrade Planning Study Project will continue to provide planning study updates and work notifications via social media, letterbox drops, emails and the Project website. We are also available to speak via telephone on 1300 794 880.
There will be no planned community events or information sessions until further notice.
We encourage you to have your say, using the contact details below. All feedback will be considered as part of the process to identify a solution that balances the needs of various stakeholders.
