The state government proposes to restructure the intersection on the Copper Coast Highway at the north end of the Yorke Highway to provide a large roundabout instead of Yorke Highway terminating at a tee-junction. The roundabout is intended to reduce delays at the end of holiday periods when lots of people try to drive back towards Adelaide at the same time, and will permit road trains to operate between Port Wakefield and Ardrossan which had previously not been permitted due to limitations of that intersection. Subsidiary works will improve the Yorke Highway north of Ardrossan with a widened bridge, sealed shoulders and overtaking lanes. Road trains up to 36.5 metres (120 ft) were previously permitted to operate on the Augusta Highway through Port Wakefield north towards Port Pirie and beyond, and from Ardrossan south to Port Giles, but were not permitted to operate north of Ardrossan to the Augusta Highway, limiting the capacity to transport grain or minerals.
