FAQs

1. What is the Hahndorf Township Strategic Traffic Planning Study?

The Australian and South Australian governments have committed $250 million to jointly fund the Hahndorf Township Improvements and Access Upgrade Project. The project will be delivered by the Department for Infrastructure and Transport (the Department).

In July 2018, the Federal Minister for Infrastructure, Transport and Regional Development committed $1 million for a strategic traffic planning study, to address traffic safety, connectivity and amenity issues in Hahndorf. Access and efficiency for heavy freight vehicles travelling to surrounding areas was also considered.

The study area included the Hahndorf Township, the existing Verdun Interchange (towards the north-west of the Hahndorf Township) and the existing Mount-Barker Interchange (towards the south-east of the Hahndorf Township).

A key aim of the study was to investigate alternative vehicle options for traffic which doesn’t have a purpose in the main street (Mount Barker Road). As the study progressed, the importance of Hahndorf’s unique heritage and character became increasingly evident. This has been considered, alongside traffic movements, in the options and ideas.

The Department has completed the initial Hahndorf Township Strategic Traffic Planning Study. Outcomes and ideas from the planning study to improve traffic safety, connectivity and liveability in and around Hahndorf are now out for public consultation until 7 June 2021..

Improving safety, access and connectivity will support Hahndorf to remain a thriving Adelaide Hills community and one of South Australia’s most loved tourism destinations.

2. What is the Hahndorf Township Improvements and Access Upgrade Project?

The Australian and South Australian governments have announced a funding investment of $250 million ($200 million in Australian Government funding and $50 million in South Australian Government funding) towards the project for planning, detailed design and construction.  It is anticipated that the scope of this project will be guided by the Hahndorf Township Strategic Traffic Planning Study and the outcomes of this community engagement process.

3. Why is the Hahndorf Township Improvements and Access Upgrade Project needed?

Without new infrastructure and upgrades in Hahndorf, the Hahndorf Township Strategic Traffic Planning Study found it is likely that:

  • Traffic and freight will continue to increase in the Hahndorf main street affecting the amenity of the township.
  • Traffic collisions are likely to increase in Hahndorf, the surrounding townships and at the existing interchange sections.
  • The performance of existing intersections will continue to decline with increased delays, queues and further disruptions to the community and businesses.
  • Growth opportunities for the local economy, which is tourism dominated, will be limited due to the road environment.

Addressing these problems will ensure that Hahndorf can continue to safely accommodate visitors and retain its role as one of South Australia’s most significant tourism hubs.

4. What is the current situation in Hahndorf?

The Hahndorf Township is a significant tourist destination located in the Adelaide Hills, drawing around one million visitors each year. Hahndorf is also located on a key transport route for both general traffic and freight vehicles.

Currently, the existing infrastructure provides no alternative route for vehicles travelling north to south (and vice versa) to avoid the main street (Mount Barker Road). This causes additional traffic along the main street, which currently carries around 11,000 vehicles per day including approximately 480 commercial vehicles. The main street has limited capacity to cope with the variety of traffic passing through, and with the traffic volume growing at about 1.9 per cent per year the safety, function and amenity of Hahndorf are facing challenges.

The main street has limited space to accommodate the many modes of traffic (e.g. heavy vehicles, buses, traffic, pedestrians etc.) that occupies the current street space (e.g. roadway, parking and footpath activities). It is also the highest pedestrianised trafficked street in SA.

5.  What are the key traffic problems in Hahndorf?

The study identified several problems in Hahndorf and the surrounding area including:

  • The nature of the current connectivity to and from the South Eastern Freeway is causing additional traffic and freight in the township, primarily due to:
  • There being no convenient alternative route between the east (Mount Barker) and the north (Balhannah/Woodside) without travelling through the main street of Hahndorf.
  • There being no convenient alternative route between the south (Echunga) and the west (Adelaide) or east (Murray Bridge) without travelling through the main street of Hahndorf.
  • The current traffic on the Hahndorf main street (Mount Barker Road) is limiting the economy, function, and amenity of the township. There are approximately 11,000 vehicles per day on the main street, which also has a very high number of pedestrians.
  • Poor wayfinding and driver behaviour is causing unnecessary congestion.
  • Limited public parking is available.
  • The limited capacity of Mount Barker Interchange is causing delay and safety risks.
  • Limited active transport (pedestrian and bike paths) infrastructure is available outside of the township.

6.  What were the key steps in the planning study process?

The Department undertook consultation and investigations as part of the study to inform, develop and assess multiple options and ideas to address the current and future traffic problems facing Hahndorf. The key steps and activities of the planning study are described below.

7. What criteria was used to develop and assess the options?

The Department assessed a long list of options and ideas against several criteria listed below. Options and ideas that did not perform well against the assessment criteria did not progress for further development.

8. Were options for a new interchange at Pine Avenue considered?

Yes. Interchange options at Pine Avenue were also investigated, however these options were not short-listed for the following reasons:

  • A new interchange at Pine Avenue does not address the key issue of removing traffic from the main street as effectively as the short-listed options for the following reasons:
    • Vehicles travelling to / from the north of Hahndorf (e.g. Woodside) would still use the main street.
    • Vehicles travelling to / from the south of Hahndorf (e.g. Echunga) would still use the main street.
    • Vehicles travelling from the south to Bridgewater, and vice-versa, would still use the main street.
  • Environmental and social impacts are greater than for the three short listed options with regards to land acquisition, vegetation removal and amenity.

9. How was community and stakeholder feedback considered?

The outcomes of consultation feedback played a significant role informing the development of the options and ideas. The feedback received early in the planning process helped to identify key issues and problems that were important to the community.  Key considerations included:

  • The future needs and desires of the community
  • Minimising the project impacts on residents and business.
  • Environmental considerations including heritage and vegetation clearance requirements.
  • Constructability considerations to ensure the options and ideas are viable.

The Department will also continue to work closely with Mount Barker Council to ensure any ideas taken forward on the main street are integrated with Council’s Revitalisation Plans.

10.What are the short-listed options?

The outcomes of the study identified three proposed interchange options (two at River Road and one at Verdun), as well as a set of ideas to improve traffic management and amenity in the main street.

Interchange options at Pine Avenue were assessed and found to provide limited benefit. They did not remove traffic from the main street and had greater impacts to vegetation, property and amenity than other options. The shortlisted options detailed below improve the connectivity and efficiency of the road network around Hahndorf, focusing on access to/from the South Eastern Freeway. As part of the project, the Department also proposes to:

  • Upgrade the Mount Barker Interchange with traffic signals at the southern intersection and ramp capacity improvements.
  • Install a dedicated and separate shared walking and cycling path connecting Verdun and Hahndorf, thus acknowledging Hahndorf’s heritage by providing the missing link to the Pioneer Women’s Trail.

River Road- Option 1

Includes a full interchange at River Road and a new link road connecting Echunga Road and River Road. The key benefits of this option are that it provides direct access for motorists travelling in all directions, significantly improving emergency service access and creating alternate routes for vehicles that currently pass through the Hahndorf main street. This option also provides travel time savings for trips between Adelaide and the South.  The benefits and limitations of this options are summarised below:

River Road-Option 2

Includes a half interchange at River Road and a link road connecting Echunga Road and River Road. The key benefits of this option are that it provides direct access for motorists travelling south, north and east, and provides alternate routes for vehicles that currently pass through the Hahndorf main street.

The benefits and limitations of this option are summarised below:

Verdun Interchange-Option 3

Includes upgrading to a full interchange at Verdun with a link road connecting Echunga Road and River Road. The key benefits of this option are improved access for motorists travelling east and alternate routes for some vehicles that currently pass through the main street. However, this option does not remove all unnecessary trips through Hahndorf.

The benefits and limitations of this option are summarised below:

Main street (Mount Barker Road) ideas

Several ideas have been identified to improve the main street of Hahndorf to address current and future amenity, safety, parking and efficiency issues. Any improvements on the main street are intended to be integrated with the Mount Barker District Council’s Revitalisation Plans as the scope is refined for the Hahndorf Township Improvements and Access Upgrade Project.

Key benefits could include:

  • Enhancements to improve pedestrian and visitor safety including better pedestrian facilities, upgraded crossings, continuous raised footpaths across side roads and raising the road to the same height as the footpath between Pine Avenue and English Street.
  • Protected right-turn lanes for vehicles turning onto Balhannah Road and Pine Avenue.
  • Gateway treatments (such as road marking, signs and landscaping) at either end of the main street to signal a change in the traffic environment.

12.   Are traffic signals at the intersection of the main street and Balhannah Road being considered?

Not at this stage, because outcomes of early investigations determined that the introduction of traffic signals at the main street and Balhannah Road would have a negative impact of traffic efficiency in the area. The set of ideas shortlisted for main street include right turn lanes to Balhannah Road and Pine Avenue to assist traffic to move along Mount Barker Road efficiently and to remove queueing from this intersection. Additionally, converting the pedestrian activated crossing to a wombat crossing will ensure consistency for pedestrian crossing facilities along main street. This will provide pedestrians the right of way when required.

13.   What are the next steps?

The outcomes of the planning study, as well as community feedback received during this consultation period, will help inform how the Department progresses the design and delivery of the Hahndorf Township Improvements and Access Upgrade Project. A decision can then be made on which option and main street ideas will provide the best possible outcome for the public overall.

Detailed planning for the Hahndorf Township Improvements and Access Upgrade Project will commence later this year, with construction likely to begin late 2023.

The Department will continue to engage with the community at each stage of the project. We encourage you to register for updates so we can keep you informed as the project progresses.
