Pan-American Highway - Southern Section of The Pan-American Highway

Southern Section of The Pan-American Highway

The southern part of the highway begins in northwestern Colombia, from where it follows Colombia Highway 62 to Medellín. At Medellín, Colombia Highway 54 leads to Bogotá, but Colombia Highway 25 turns south for a more direct route. Colombia Highway 72 is routed southwest from Bogotá to join Highway 25 at Murillo. Highway 25 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 (Llaillay), where the highway splits into two parts, one of which goes through Chilean territory to Quellón on Chiloé Island, after which it continues as the Carretera Austral. The other part goes east along Chile Highway 60, which becomes Argentina National Route 7 at the Argentinian border and continues 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 in Tierra del Fuego.

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.

A continuation of the Pan-American Highway to the Brazilian cities of São Paulo and 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 Brazilian main cities.

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 any of the island nations in the Americas. 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. Belize was supposedly included in the route at one time, as they switched which side of the road they drive on. As British Honduras, they were the only Central American country to drive on the left side of the road.
