Pan-American Highway recognized as world's longest motorway spanning 30,000 miles across 14 countries
The Pan-American Highway is the world's longest motorway, stretching 30,000 miles across 14 countries in North and South America. It connects southern Argentina to Alaska, with a notable break in the Darien Gap. Originally proposed as a railway in 1884, the highway was later developed as a motorway, with construction starting in 1937. The final section was completed in 1963, and it is recognized by Guinness World Records as the longest motorable road. Traveling the entire highway can take months, with the fastest recorded trip completed in 24 days. In comparison, the longest motorway in Europe, the E40, spans 4,971 miles from Calais, France, to Ridder, Kyrgyzstan.
