New centreline safety treatment on Dukes

In a South Australian first, centreline treatment has been used on the Dukes Highway to increase the distance between vehicles travelling in opposite directions.

The new, wide lines have been in place from 9 March on a 6.5 kilometre stretch of the Dukes Highway between Tailem Bend and Coomandook.

The centreline markings consist of two parallel white lines 1.2 metres apart. The gap provides time for errant drivers to recover and return to their lane before they cross into the path of oncoming traffic.

A total of 39 kilometres of the centreline treatment will be installed this year, with audio tactile line markings to be added in April, weather permitting.

Once the audio tactile line markings are installed, the lines will generate a vibration and buzzing sound which will alert the driver they are drifting onto the wrong side of the road.

This will reduce crashes caused by fatigue and driver inattention, as there will be increased distance between vehicles travelling in opposite directions and additional warning to drivers that have left their travelling lane.

In locations where overtaking is allowed, the new widened markings will be dashed lines, while solid lines will indicate overtaking is not permitted.

For more information visit or call 1300 728 274.
