Roads have long served as vital arteries connecting distant lands, facilitating trade, travel, and cultural exchange. As technology advances and infrastructural marvels unfold, the world witnesses the emergence of longer and more intricate road networks. In this article, we embark on a journey to discover the longest roads on the planet in 2024, marveling at the engineering feats that link nations and traverse continents.
The Pan American Highway stands as the undisputed champion of road networks, earning the prestigious title of the longest road in the world as of 2024. Stretching an astonishing 30,000 kilometers (19,000 miles), this epic journey begins its odyssey in Prudhoe Bay, Alaska, before embarking on an awe-inspiring voyage all the way down to Ushuaia, Argentina.
While Guinness World Records lauds the Pan American Highway as the longest “motorable road,” it’s essential to note a natural obstacle along the route. A 106-kilometer (66-mile) expanse known as the Darien Gap separates South and Central America, presenting a formidable challenge for adventurers. Travelers seeking to conquer this stretch by land must endure a four-day hike, while those opting for convenience can cross the gap via ferry from Panama to Colombia.
Pan American Highway, with the total of 30,000 km, holds the title of the longest road in the world, followed by Highway 1, Trans-Siberian Highway, G219, and WE-WC Highway.
Here is the list of top-10 longest roads in the world 2024:
