While India’s NH-44 is the country’s longest road, stretching 4,112 kilometres, it’s far from the longest on Earth. That title goes to the Pan-American Highway, a giant road that covers about 30,600 kilometres (or 19,000 miles), more than seven times longer than NH-44!

This incredible highway starts in Prudhoe Bay, Alaska, and goes all the way down to Ushuaia, Argentina, at the very tip of South America. What’s amazing is that drivers can travel the whole distance without ever needing to take a U-turn.

The idea for the Pan-American Highway came up in the early 1920s to help people travel easily across the Americas and to boost tourism. By 1937, 14 countries had agreed to be part of the project. The road officially opened in 1960.

The 14 countries along the way are: Canada, the United States, Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Ecuador, Peru, Chile, and Argentina.

Each country takes care of the part of the highway that lies within its borders.

Driving along this highway is like flipping through the pages of a nature book. You’ll see snowy mountains, dry deserts, thick forests, and beautiful coastlines. Every stretch of road offers something new to look at.

If you drove about 500 kilometres a day, it would still take more than two months to finish the whole journey!

The Pan-American Highway is not only the longest motorable road in the world, it’s also one of the straightest. It’s a symbol of how countries can work together to build something amazing that connects people across continents.

It’s not just a way to travel—it’s a journey through the heart of the Americas.
