The original Granite Island Causeway was an iconic landmark with considerable heritage value. The Causeway, located 83 km south of Adelaide, at Victor Harbour, on the Fleurieu Peninsula, is the only link between Granite Island and the mainland at Victor Harbor and is a site of cultural significance to the traditional owners of the area. The Causeway is also a popular tourist attraction, important to the local, regional and state economies. A condition assessment identified that the old Causeway was approaching the end of its useful life and a feasibility study into the potential upgrade options determined that retaining the old structure was not viable. The South Australian Government committed $43 million of funding towards the Granite Island Causeway Project delivered by The Department for Infrastructure and Transport (DIT). The new Granite Island Causeway continues to deliver and enhance social and economic benefits to the region and provides a long-term solution that is environmentally sensitive.
