The longest continuous road in the world - Highway One, Australia
Australia's Highway One gets the nod as the longest road in the world. It actually circumnavigates the whole of the vast country via a network of fully interconnected roads. Its total length is 9,024 miles (14,523km), which makes it over 2,200 miles (3,540km) longer than its nearest rival, the Trans-Siberian Highway.
Over a million people drive on Highway One every day, with the road passing through every state in Australia, but they’d need a lot more than a day to drive all the way around it.
