The Copper Coast Highway (route ) is a highway in South Australia which branches off from the Augusta Highway 2 km north of Port Wakefield and heads northwest across the top of Yorke Peninsula to Kadina and ends at the Spencer Gulf town of Wallaroo.


In 2016, the state government proposed 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.[2] 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 improved the Yorke Highway north of Ardrossan with a widened bridge, sealed shoulders and overtaking lanes.[3] 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,[4] limiting the capacity to transport grain or minerals. Work commenced on the roundabout in October 2017 and it was completed in January 2018.[5]

A proposal by the Liberal Party of Australia before the 2018 state election was that if it was elected it would build a single lane overpass at the Augusta Highway end of the Copper Coast Highway to reduce traffic conflicts.[6]
