Towns on the Dukes Highway, South Australia

From Tailem Bend, the Dukes Highway makes its way out of the Coorong region, through Coomandook, Coonalpyn and Tintinara.

The next town of any decent size is Keith, where the Dukes Highway meets the Riddoch Highway. Turn off here if you want to head south to Naracoorte and Mount Gambier.

The next junction of any importance is with the Ngarkat Highway at Cannawigara. And the final stop before crossing into Victoria is the unimaginatively-named Bordertown. Here, the Naracoorte Road branches off, again going to Naracoorte and Mount Gambier, but in a slightly different direction.
