15 August - New Interchange Open
A faster, safer commute for Mount Barker motorists
A new traffic interchange is now officially open on the South Eastern Freeway – improving access, safety, and travel times for tens of thousands of people.
The interchange provides more efficient access on and off the freeway via Bald Hills Road reducing traffic congestion through Littlehampton and Mount Barker and will improve travel times and road safety for commuters travelling to the east side of Mount Barker and reduce congestion in Mount Barker.
As well as giving commuters a better run to their destinations, the new interchange will also enable tourists to move around the Adelaide Hills easier, and improving freight transport.
Commencing in June 2015, the $27m project is jointly funded with the Australian Government contributing $16 million, the South Australian Government $8 million and the District Council of Mt Barker $3 million.
Little Dublin Road West Closure
The State Government's contractor Bardavcol have advised it will be necessary to close the Little Dublin Road West entrance to traffic for a period of approximately 2 weeks commencing 6 July 2016.
Detour to Access Yaktanga Way Friday 20 May
To facilitate the sealing of Bald Hills Road south of the South Eastern Freeway, the contractor intends to place asphalt past the Yaktanga Way/Bald Hills Road intersection on Friday 20 May 2016 between the hours of 7.00am to 3:00pm.
A detour to direct all Yaktanga Way traffic via Burnbank Way to Bald Hills Road will be sign posted.
The contractor will undertake a letterbox drop to local residents with the message being reiterated using variable message boards.
All Ramps to be open by September 2016
The New Freeway Interchange construction is progressing well. The State Government has advised that it expects all ramps to be open by September 2016 under a speed restriction with completion of all work by the end of 2016.
Bald Hills Road Closed 17 April 2016 for Interchange Work
17 April 2016
Road works are progressing well along Bald Hills Road. Bardavcol anticipates the majority of the work will be completed by Mid 2016. However, to ensure Bardavcol meets this date and to minimise the overall period of disruption, it will be necessary to close the Bald Hills Road Underpass.
This work will take place on Sunday 17 April 2016 between the hours of 6:00am and 6:00pm. During this time, Bald Hills Road will be closed between Springs Road and Old Princes Highway with the exception of local traffic only. Please note that Bald Hills Road will be completely closed at the Bald Hills Road Underpass. Local traffic needing access north of the South Eastern Freeway, will need to be from Old Princes Highway and local traffic needing access to the South of the South Eastern Freeway, must be from Springs Road. Traffic management and signage will be in place to advise of the detour and to assist traffic.
The road will be reopened as per current conditions at the end of this shift. Regular daytime construction works will continue as normal on Monday 18 April.
We apologise for any inconvenience caused during this work but assure you every effort will be made to minimise impact during this period.
If you have any queries related to this work please call Project Manager – Daniel Kranixfeld on 0419 851 965.

27 March 2015
Using Council’s concepts for the interchange, the Department of Planning, Transport and Infrastructure has developed a plan for the new interchange and has invited property owners adjacent to the new freeway interchange to attend a meeting at the Mount Barker Golf Club on Wednesday 8 April at 6pm to discuss the plan. Adjacent residents are encouraged to attend.
What’s happening now?
The Hon Jamie Briggs MP and Mayor Ferguson today announced the commencement of vegetation removal works for the new freeway interchange.
DPTI is commencing tree removal to allow construction of the New Interchange on 8 December 2014. Tree removal is limited to the Sate Government owned Freeway Reserve (see Plan). Council is still in discussion with DPTI about trees along Bald Hills Road to determine where high values native trees can be retained through design adjustments.
DPTI has completed the engineering and environmental surveys and prepared a concept based on the scheme prepared by Council in 2008/09. Tenders have been called for the project and while no dramatic changes are expected to be made to this design, the final design will be available in early 2015.
Noise: As with any DPTI infrastructure projects involving new roads or major upgrades, noise modelling was undertaken to predict future noise impacts of the project.
The consultant AECOM has confirmed that as future noise levels (based on our modelling) will not exceed noise Guidelines and no noise attenuation is required.
Vegetation Removal: While the ramp design has been developed with the aim of minimising vegetation removal, there are a lot of trees and other vegetation which need to be removed to make way for the interchange. Vegetation removal will begin on Monday December 8. Large logs will be gifted to Council for landscape works within the Council district.
The landscape scheme based on local native plant species will integrate the site into the surrounding landscape character while taking into account biodiversity values.
In addition to the landscaping, DPTI will meet obligations under the Native Vegetation Act - Significant Environmental Benefit offset requirements through a substantial payment into the Native Vegetation Fund.

Roundabout at Old Princes Highway and Bald Hills Road
Stage 1 includes construction of a roundabout at Old Princes Highway and Bald Hills Road.
DPTI Commences Community Engagement
DPTI will be engaging with directly affected residents in late July 2014.
This will be followed by broader community engagement where the proposed interchange scheme will be placed on display for public comment from Thursday 24 July 2014 – Friday 8 August 2014 at the Mount Barker Library, 5 Dumas Street, Mount Barker.
DPTI Project staff will be present at the Library to answer any questions on Thursday 24 July 2014 between 6.30pm - 8.00pm.
Designs & Simulation
Further information on the designs is available on DPTI's website: http://www.infrastructure.sa.gov.au/road_projects/bald_hills_road_interchange
DPTI have advised that investigative works will be undertaken to build on that already obtained by Council when the concepts for the interchange in this location were developed in 2008/09. Surveyors will be gathering engineering data to help prepare a design which is expected to be released for public communication and comment in June 2014.
Council has identified the New Interchange as a key infrastructure requirement for the Ministerial Development Plan Amendment (MDPA). The State Government has indicated that a New Interchange will be provided to cater for the MDPA impacts.
State and Federal Governments have confirmed that construction has been budgeted for the next two years. The Department of Transport Energy and Infrastructure has commenced preliminary design work.
State and Federal Governments Award Tender
The State and Federal Governments have announced the award of the Tender to build the new interchange including both the Adelaide and Murray Bridge direction on and off ramps.
The project also includes a roundabout to improve safety at the intersection of Old Princes Highway and Bald Hills Road.
Construction is expected to commence in mid 2015.
State and Federal Governments Call Tender for Design and Construction
State and Federal Goverments Release Design Plans
Further information on the designs is available on DPTI's website: http://www.infrastructure.sa.gov.au/road_projects/bald_hills_road_interchange
State and Federal Governments have confirmed that construction has been budgeted for the next two years. The Department of Transport Energy and Infrastructure has commenced preliminary design work

Council Continues to Advocate
Council recognised that a second interchange was required and proactively developed concept designs and at the meeting held on 16 November 2009, approved the amended Options A and B to enable Council to enter into discussions with the State and Federal Governments for funding for the new interchange. Final design will be determined by the State Government.
The State Government rezoned land in 2010, but did not provide any mechanism for infrastructure provision (including roads, sewer, water, electricity etc). The State Government has since prepared an Infrastructure Deed which Developers who have land in the rezoned area are to be party to. The Deed requires that Adelaide facing on off ramps are required within 5 years but this will be subject to funding from the Developer Fund established by the Deed. Other elements of the interchange have been listed as longer term in the Deed.
Council continues to advocate for funding for the interchange at every opportunity.
Impact on Yaktanga Way of Freeway Interchange on Bald Hills Road
An “origin-destination” number plate survey was carried out by MFY Traffic Engineers in 2011 to:
- Assess the existing extent of traffic cut-through using Yaktanga Way, and
- Provide advice as to the likelihood of increasing traffic volumes on Yaktanga Way should a future interchange be built on Bald Hills Road.
The reporting summarises that:
The number plate survey has identified that there are minimal cut-through movements on Yaktanga Way and that traffic entering/exiting Dalmeney Park and Waterford Estate typically relate to local resident trips.
There would be an increase in traffic volume in Yaktanga Way if the new South Eastern Freeway interchange was constructed but this would primarily relate to commute trips by local residents in the estate to/from the freeway.
Since the number-plate survey and reporting were completed, Bald Hills Road upgrade construction and the Springs Road roundabout have been completed. These works are likely to have made the Bald Hills/Springs Road route more appealing to road users which is expected to further reduce any cut-through movement along Yaktanga Way.
Traffic volumes will be monitored before and after a freeway interchange has been constructed so that an assessment can be made of the actual effect of the new Interchange. Council will then assess whether there is any need for further measures such as traffic calming and further consult with residents before any changes are made.
Liberals Pledge Support
The Liberals pledge supportto fund half the cost of a new freeway interchange at Bald Hills Road if a Coalition Federal Government is elected.
Concept Design Options Approved by Council
At the meeting held on 16 November 2009, Council received a report including the final Concept Design Report and approved the amended Options A and B for discussion with the State and Federal Governments re funding for the new interchange.
Progress Reports to Council
Council has responded to Community Feedback by introducing roundabouts at the New Interchange ramp junctions with Bald Hills Road. The ramps to the north have also been moved away from the underpass to improve safety. Construction of a New Freeway Interchange will be subject to provision of funding from the State and/or Federal Governments. The Amended Concept Design Options will provide a strong base for further funding applications.
Tunnel Upgrade and Bridge Options
Concepts for Tunnel Upgrade and Bridge Options are shown below. These are indicative concepts which show how the current Tunnel could be lowered to improve its clearance if sufficient funding is not available immediately to provide a new Bridge. The final design of either option may vary depending on budget availability and State and Federal requirements.
A report has been prepared by an Independent Arborist on trees that could be affected by the two alternative concept design options. An additional report has been prepared to cater for the amended Concept Design Options.
