  Due to the Andes Mountains, Amazon River and Amazon Forest, there have always been difficulties in implementing larger scale transcontinental or bioceanic highways. Practically the only route that existed was the one that connected Brazil to Buenos Aires, (in Argentina) and later to Santiago, (in Chile). However, in recent years, with the combined effort of countries, new routes have started to emerge, such as Brazil-Peru (Interoceanic Highway), and a new highway between Brazil, Paraguay, northern Argentina and northern Chile (Bioceanic Corridor).
  
  Some of the most modern roads extend through northern and south-east Argentina; and south of Brazil, a vast road complex aims to link Brasília, the federal capital, to the South, Southeast, Northeast and Northern regions of Brazil.
  
  Brazil has more than 1.7 million km of roads, of which 215,000 km are paved, and about 14,000 km are divided highways. The two most important highways in the country are BR-101 and BR-116. Argentina has more than 600,000 km of roads, of which about 70,000 km are paved, and about 2,500 km are divided highways. The three most important highways in the country are Route 9, Route 7 and Route 14. Colombia has about 210,000 km of roads, and about 2,300 km are divided highways. Chile has about 82,000 km of roads, 20,000 km of which are paved, and about 2,000 km are divided highways. The most important highway in the country is the Route 5 (Pan-American Highway) These 4 countries are the ones with the best road infrastructure and with the largest number of double-lane highways.
  
  In addition, there is a reputed Pan-American Highway, which crosses Argentina and the Andean countries from north to south, although various stretches are unfinished.
