Wilmington–Ucolta Road

Wilmington–Ucolta Road is a 98 kilometre major road connecting Port Augusta to Peterborough and beyond to Broken Hill, in South Australia. It forms as a connecter road between the Princes Highway and the Barrier Highway through the Flinders Ranges, and forms the most direct path between Port Augusta in South Australia (and following destinations like Alice Springs, Darwin, Kalgoorlie, and Perth) and Dubbo (and following destinations like Moree, Tamworth, Orange, and Newcastle), and hence provides the most direct link between Port Augusta and Sydney.
