The Pan American Highway from Prudhoe Bay, Alaska to Ushuaia, Argentina.
The 'Pan-American Highway' (see
below for its name in all languages) is a network of
roads nearly 48,000 kilometres (29,800 miles) in total length. Except for an 87 kilometre (54 mi) rainforest gap, the road links the mainland nations of the
Americas in a connected highway system. According to The Guinness Book of World Records, the Pan-American Highway is the world's longest "motorable road".
The Pan-American Highway system is mostly complete and extends from
Fairbanks, Alaska in
North America to the lower reaches of
South America. Several highway termini are claimed to exist, including the cities of
Puerto Montt and
Quellón in
Chile and
Ushuaia in
Argentina. 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 section between the United States and the Panama Canal: this part is quite popular among US tourists driving into
Mexico). Both of these sections were built during World War II as a means of supply of remote areas without danger of attack by U-boats.
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 Pan-American Highway travels through the following 15 countries:
★
Canada (unofficially)
★
United States (unofficially)
★
Mexico
★
Guatemala
★
El Salvador
★
Honduras
★
Nicaragua
★
Costa Rica
★
Panama
★
Colombia
★
Ecuador
★
Peru
★
Chile
★
Argentina
Important spurs also lead into
Bolivia,
Brazil,
Paraguay,
Uruguay and
Venezuela.
For
tourism purposes, the Pan-American Highway north of Central America 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 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 (first bicycle crossing by Chris Bechard and Scott Kiekhaefer, January 1981),
motorbike,
all-terrain vehicle, and foot, dealing with
jungle,
quicksand,
swamp,
insects, and other hazards.
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. The Darién area is disputed by the Colombian paramilitary group
AUC and its Marxist anti-government rivals
FARC and
ELN, a state of affairs which could disrupt construction works and driving through the highway afterwards.
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
Gulf of 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)
The Northern Section of the Pan-American Highway

No road in the U.S. or Canada has been officially designated as the Pan-American Highway, and thus the primary 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.
U.S. Route 85, which goes north from El Paso, is designated the CanAm Highway, which continues into Canada in the province of
Saskatchewan, before terminating at
La Ronge.
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
From Mexico City to the border with
Guatemala, the Highway follows
Mexican Federal Highway 190. Through the
Central American countries, it follows
Central American Highway 1, ending at
Yaviza, Panama at the edge of the
Darién Gap. The road had formerly ended at
Cañita, Panama, 110 miles (178 km) north of its current end. United States government funding was particularly significant to complete a high-level bridge over the
Panama Canal, during the years when the canal was administered by the United States.
The Southern Section of the Pan-American Highway

Quellón that describes the city as the end of the Pan American highway
The southern part of the highway begins in northwestern Colombia, from where it follows
Colombia Highway 52 to
MedellÃn. At MedellÃn,
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 National Route 7 (and possibly partly
Argentina National Route 8) to
Buenos Aires, the end of the main highway. The highway network also continues south of Buenos Aires along
Argentina National Route 3 towards the city of Ushuaia and
Cape Horn.
One branch, known as the
Simón BolÃvar 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.
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.
Another branch, from Buenos Aires to
Asunción in
Paraguay, heads out of Buenos Aires on
Argentina National Route 9. It switches to
Argentina National Route 11 at
Rosario, which crosses the border with Paraguay right at Asunción. Other branches probably exist across the center of South America.
The highway does not have official segments to
Belize,
Guyana,
Suriname and
French Guiana, nor to the assorted islands in the Caribbean region. However, highways from Venezuela link to Brazilian
Trans-Amazonian highway that provide a southwest entrance to Guyana, route to the coast, and follow a coastal route through Suriname to French Guiana.

In art and culture
The Pan-American highway is the subject of a recent (as of
2006) conceptual art piece, ''
The School of Panamerican Unrest'', where Mexican-born artist
Pablo Helguera is attempting to drive a portable schoolhouse for the length of the entire route.
The travel writer
Tim Cahill wrote a book, ''Road Fever'', about his record-setting 24-day drive from
Ushuaia in the Argentine province of
Tierra del Fuego to
Prudhoe Bay in the U.S. state of
Alaska with professional long-distance driver
Garry Sowerby, much of their route following the Pan-American Highway.
