Stretching like an infinite ribbon through the heart of the Australian Outback, the 90-Mile Straight is a marvel of human engineering and nature’s vastness. This segment of the Eyre Highway is not only the longest straight road in Australia but also a symbol of the country’s rugged allure and adventurous spirit.
