The Pan-American Highway: The World's Longest Road Trip from Alaska to Tierra del Fuego
Imagine sharing road trip dreams with friends: a convertible cruise through the South of France, a jeep safari in Africa, or the legendary Route 66 from Chicago to Los Angeles. Top them all with the Pan-American Highway (PAH)—the ultimate adventure spanning 30,000 miles (48,000 km) from Prudhoe Bay, Alaska, to Ushuaia in Tierra del Fuego, Argentina.
This iconic route tests your vehicle, drops your jaw at stunning vistas, and fuels endless stories to impress fellow travelers.
History of the Pan-American Highway
The concept emerged in 1889 at the First International Conference of American States, where the U.S. proposed a continent-wide railroad. It gained traction in 1923 at the Fifth International Conference in Chile, with formal approval in 1928 at the sixth conference in Cuba.
Originally planned from Laredo, Mexico, to Buenos Aires, Argentina, U.S. funding was pivotal despite no official U.S. segment. Challenges like wars, funding shortages, and political hurdles slowed progress, but today, you can drive most of the Americas' length by car.
The Route Overview
No single path defines the PAH. The official core stretches from Laredo, Mexico, to Buenos Aires, with branches extending the full north-south journey to nearly 30,000 miles (48,000 km).
North America
Begin in Prudhoe Bay, Alaska, heading south through Canada into the U.S. The U.S. designates all interstates as PAH parts; prime north-south freeways link to Mexico's official route, showcasing epic landscapes, charming towns, and cities like Los Angeles, Las Vegas, and San Diego.
From Laredo (across from Texas' San Antonio), it reaches Mexico City, joined by a parallel Pacific coast branch.
Central America
The highway threads through every Central American capital except Honduras' Tegucigalpa (bypassing it 60 miles/100 km south), until the impassable Darién Gap—a 50-mile (80 km) jungle-mountain barrier between Panama and Colombia.
Environmental protections and indigenous opposition prevent road construction. Travelers fly across, shipping vehicles in containers. Avoid biking or hiking due to treacherous terrain and security risks from smuggling activities.
South America
Resuming in Turbo, Colombia, the route hugs South America's Pacific coast through Ecuador (Quito), Peru (Lima), and Chile. Branches split: one to Quellón, the main to Buenos Aires; others to Uruguay, Brazil (São Paulo, Rio), or south to Patagonia's wonders and Ushuaia, the southern terminus.
