The second Mount Barker Freeway Interchange will change access to & from Mount Barker and will impact on surrounding towns in the Adelaide Hills & beyond.
With the current Freeway Interchange reaching capacity in both volume & frustration levels the second interchange will be a real benefit to residents of Mount Barker, Littlehampton, Nairne and visitors from the direction of Murray Bridge.
The second interchange being built features 2 roundabouts on Bald Hills Road to enable smooth traffic flows to the on off ramps on the South Eastern Freeway. There is also an additional roundabout being constructed at the intersection of Bald Hills Road & the Old Princes Highway Nairne. This roundabout is to manage traffic flows in a much safer & timely fashion.
It is anticipated that the on ramp will be completed in February 2016 and the whole project completed by October 2016.
There will be many positive impacts from this project for Mount Barker & surrounding Districts.
Mount Barker will see improved traffic flows to and from Adelaide. It is also envisaged that the diversion of traffic away from Adelaide Road will lead to smoother traffic flows through the centre of Mount Barker.
Nairne will see quicker travel times to and from Adelaide. The improvements to the Bald Hills Road & Old Princes Highway intersection near Nairne will dramatically improve safety at that intersection. Nairne has tremendous potential at this time for investors in particular.
Littlehampton will see reduced traffic volumes through its main street, particularly at peak commuting times.
Murray Bridge & the Monarto South employment lands will benefit greatly from easier access to Mount Barker and to the Totness, Hahndorf, Littlehampton side of town.

Some secondary impacts are expected such as increased traffic flows on the Nairne Wodside Road. There will be more congestion at the Adelaide end of the Freeway as well but this is more a factor of increased population growth in Mount Barker & surrounds rather than the second freeway interchange.
