Pan-American Highway
Encyclopedia : P : PA : PAN : Pan-American Highway
The Pan-American Highway (see below for its name in all languages) is a network of roads nearly 48,000 km (29,800 miles) in total length. Except for an 87 km rainforest gap, the road links the mainland nations of the Americas in a connected highway system.
The Pan-American Highway system is mostly complete and extends from Fairbanks, Alaska in North America to Quellón, Chile in South America, though no route is officially defined in Canada and the United States.
The Pan-American Highway passes through many diverse climates and ecological types, from dense jungles to cold mountain passes. Since the highway passes through many countries, it is far from uniform. Some stretches of the highway are passable only during the dry season, and in many regions driving is occasionally hazardous.
Famous sections of the Pan-American Highway include the Alaska Highway and the Inter-American Highway, the latter being the section between the United States and the Panama Canal. This part is quite popular among US tourists driving into Mexico.
Jake Silverstein, writing in 2006, described the Pan-American Highway as "a system so vast, so incomplete, and so incomprehensible it is not so much a road as it is the idea of Pan-Americanism itself…" (Silverstein, p. 71)
The Darién Gap
-->The notable stretch that keeps the highway from being completely connected is a section of land between the Panama Canal in Panama and the Colombian border called the Darién Gap, which is a 54 mile (87 km) stretch of rainforest. The gap has been crossed by adventurers on bicycle, motorbike, all-terrain vehicle, and foot, dealing with jungle, quicksand, swamp and insects.
There are many people, groups, indigenous populations and governments that are opposed to completing the Darién portion of the highway, with reasons as varied as the desire to protect the rain forest, containing the spread of tropical diseases, protecting the livelihood of indigenous peoples in the area, and preventing foot and mouth disease from entering North America. Experience with the extension as far as Yaviza included severe deforestation within a decade alongside the highway route.
One option proposed, in a study by Bio-Pacifico, is a short ferry link from Colombia to a new ferry port in Panama, with an extension of the existing Panama highway that would complete the highway without violating these environmental concerns. The ferry would cross the Golfo de Urabá from Turbo, Colombia, to a new Panamanian port (possibly Carreto) connected to a Caribbean coast extension of the highway. Efficient routing would probably dictate that the existing route to Yaviza be relegated to secondary road status.
Development and completion
The concept of a route from one tip of the Americas to the other was originally proposed at the First Pan-American Conference in 1889 as a railroad; however, nothing ever came of this proposal. The idea of the Pan-American Highway emerged at the Fifth International Conference of American States in 1923, where it was originally conceived as a single route. The first Pan-American highway conference convened October 5, 1925 in Buenos Aires. Mexico was the first Latin American country to complete its portion of the highway, in 1950. (Silverstein, p. 71)North of the Darién Gap
No road in the U.S. or Canada has been officially designated as the Pan-American Highway, and thus the road officially starts at the U.S.-Mexico border. The original route began at the border at Nuevo Laredo, Tamaulipas (opposite Laredo, Texas) and went south through Mexico City. Later branches were built to the border at Nogales, Sonora (Nogales, Arizona), Ciudad Juárez, Chihuahua (El Paso, Texas), Piedras Negras, Coahuila (Eagle Pass, Texas), Reynosa, Tamaulipas (Pharr, Texas), and Matamoros, Tamaulipas (Brownsville, Texas).
On the other hand, several roads in the U.S. were locally named after the Pan-American Highway. When the section of Interstate 35 in San Antonio, Texas was built, it was named the Pan Am Expressway, as an extension of the original route from Laredo. Interstate 25 in Albuquerque, New Mexico has been named the Pan-American Freeway, as an extension of the route to El Paso.
The original route to Laredo travels up Mexican Federal Highway 85 from Mexico City. The various spurs follow:
- Nogales spur - Mexican Federal Highway 15 from Mexico City
- El Paso spur - Mexican Federal Highway 45 from Mexico City
- Eagle Pass spur - unknown, possibly Mexican Federal Highway 57 from Mexico City
- Pharr spur - Mexican Federal Highway 40 from Monterrey
- Brownsville spur - Mexican Federal Highway 101 from Ciudad Victoria
South of the Darién Gap
The southern part of the highway begins in northwestern Colombia, from where it follows Colombia Highway 52 to Medellín. At Medellín, Colombia Highway 54 leads to Bogotá, but Colombia Highway 11 turns south for a more direct route. Colombia Highway 72 is routed southwest from Bogotá to join Highway 11 at Murillo. Highway 11 continues all the way to the border with Ecuador.Ecuador Highway 35 runs the whole length of that country. Peru Highway 1 carries the Pan-American Highway all the way through Peru to the border with Chile.
In Chile, the highway follows Chile Highway 5 south to a point north of Santiago. The highway turns east there on Chile Highway 60, which becomes Argentina Highway 7 (and possibly partly Argentina Highway 8) to Buenos Aires, the end of the main highway.
A continuation of the Pan-American Highway to the Brazilian city of Rio de Janeiro uses a ferry from Buenos Aires to Colonia in Uruguay and Uruguay Highway 1 to Montevideo. Uruguay Highway 9 and Brazil Highway 471 route to near Pelotas, from where Brazil Highway 116 leads to Rio de Janeiro.
One branch, known as the Simón Bolívar Highway, runs from Bogotá (Colombia) to Guiria (Venezuela). It begins by using Colombia Highway 71 all the way to the border with Venezuela. From there it uses Venezuela Highway 1 to Caracas and Venezuela Highway 9 to its end at Guiria.
Another branch, from Buenos Aires to Asunción in Paraguay, heads out of Buenos Aires on Argentina Highway 9. It switches to Argentina Highway 11 at Rosario, which crosses the border with Paraguay right at Asunción.
Other branches probably exist across the center of South America.
For tourism purposes, the Pan-American Highway is sometimes assumed to use the Alaska Highway and then run down the west coast of Canada and the United States, running east from San Diego, California and picking up the branch to Nogales, Arizona.
The Pan-American Highway travels through the following 15 countries:
- Canada
- United States
- Mexico
- Guatemala
- El Salvador
- Honduras
- Nicaragua
- Costa Rica
- Panama
- Venezuela
- Colombia
- Ecuador
- Peru
- Chile
- Argentina
