St Vincent Highway (route B88) is a major road on the southern part of Yorke Peninsula in South Australia.
It diverges from Yorke Highway to continue south along the coast of Gulf St Vincent (where Yorke Highway turns inland) near Pine Point.
It passes inland of Port Vincent, Stansbury, Wool Bay and Port Giles then passes through Coobowie and Edithburgh.
[3] Rex Minerals propose to realign the northern end of the current St Vincent Highway closer to the coast, and move the intersection with the Yorke Highway closer to Pine Point as part of the construction of the Hillside mine.
[4] St Vincent Highway is entirely contained within the Yorke Peninsula Council local government area.
