Proposed new road designs in Hahndorf to ease traffic and increase safety

Hahndorf traffic study

Improved access and road safety in and around the Adelaide Hills township of Hahndorf are a step closer with the release of the Hahndorf Strategic Traffic Planning Study.

Hahndorf has long been known in Adelaide for its German heritage comprising of artisanal food, unique architecture, and an array of speciality bakeries, cafes, pubs and delicatessens – all situated in the beautiful Adelaide Hills. One thing Hahndorf would like not to be known for, is its often congested traffic on the main street. New plans for road design improvements and an Access Upgrade Project hope to make this a thing of the past.

“Hahndorf is one of South Australia’s premier tourism destinations with around one million visitors each year and traffic volume on the main street is growing by 1.9 percent annually,” the Deputy Prime Minister said.

Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development Michael McCormack said the project will improve safety for the growing number of visitors accessing the township while supporting 350 full-time-equivalent jobs during construction.

“Currently, there is no convenient alternative route for freight vehicles travelling northbound or southbound through the local area, so they need to use Mount Barker Road to get where they need to go,” South Australia’s Minister for Infrastructure and Transport Corey Wingard said.

“Three alternative route options have been identified to provide access to and from the South Eastern Freeway, along with a set of ideas to improve traffic management and amenity in the main street.”

“Traffic data reveals approximately 11,000 vehicles use the main street per day, including 480 heavy vehicles. Two-thirds of weekday peak hour traffic are trips to or from the south of the town and 300 peak-hour road users have no purpose in the main street of Hahndorf.”

A total of 32 crashes were reported along Mount Barker Road, Hahndorf, between 2015 and 2019, resulting in two serious injuries and 34 minor injuries.

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

The project is jointly funded with the Australian Government committing $200 million and the South Australian Government $50 million.

Community feedback is being sought on the 3 options for alternative traffic routes produced as the outcome of the study to find out more about the project and provide your feedback please visit the project webpage
