Joint release with:

Hon. Stephen Mullighan MP

SA Minister for Transport and Infrastructure

The Australian and South Australian governments are getting on with building vital infrastructure for the Adelaide Hills with early works on the new Bald Hills Road Interchange in Mount Barker commencing today.

Vegetation removal and clearing works have now commenced with new permanent construction fencing also being installed to define the project worksite.

This interchange is the number one infrastructure priority for the region and will significantly improve the road network at Mount Barker.

The first stage of works will involve the construction of an off-ramp and an on-ramp to and from Adelaide to support the high volume of commuter traffic during peak periods.

We are also building more for less by installing a new roundabout at the junction of Old Princes Highway and Bald Hills Road to improve safety and accommodate increased traffic volumes.

This project will support around 90 new jobs during construction with major works set to commence in early 2015 and project completion by mid-2016.

These upgrades are part of our joint record investments in world class infrastructure across South Australia to grow the economy, slash travel times and create thousands of new jobs.

The Adelaide on-ramp has been designed to minimise environmental impacts and vegetation removal with any residual materials being gifted to District Council of Mount Barker for landscape works within the Council district.

Significant environmental benefit offsets will also be made to the Offset Fund of the Native Vegetation Council to comply with the Native Vegetation Act.

Once complete, the Bald Hills Road interchange will reduce traffic congestion through Littlehampton and Mount Barker, meaning motorists will spend less time stuck in traffic and more time being productive at work or at home with their families.

For freight operators in the industrial area east of Mount Barker, the upgrades will allow trucks to avoid driving through central Mount Barker, saving time and money.

The Australian Government has committed $16 million to build the new interchange, with the South Australian Government contributing $8 million and Mount Barker Council $3 million.
