Due to the [[Andes Mountains]], [[Amazon River]] and [[Amazon Forest]], there have always been difficulties in implementing larger scale transcontinental or bi-oceanic 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 ([[Central Bi-Oceanic railway|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 {{convert|1.7|e6km|e6mi|abbr=off}} of roads, of which {{convert|215,000|km|mi|abbr=on}} are paved, and about {{convert|14,000|km|mi|abbr=on}} are [[divided highways]]. The two most important highways in the country are [[BR-101]] and [[BR-116]].<ref name="auto1">{{Cite web|url=https://anuariodotransporte.cnt.org.br/2018/#|title=Anuário CNT do Transporte|website=anuariodotransporte.cnt.org.br|access-date=4 December 2020|archive-date=11 November 2019|archive-url=https://web.archive.org/web/20191111012349/http://anuariodotransporte.cnt.org.br/2018/|url-status=live}}</ref> Argentina has more than {{convert|600,000|km|mi|abbr=on}} of roads, of which about {{convert|70,000|km|mi|abbr=on}} are paved, and about {{convert|2,500|km|mi|abbr=on}} are divided 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.<ref>{{Cite web|url=http://earthobservatory.nasa.gov/IOTD/view.php?id=88271|title=A Gap in the Andes: Image of the Day|date=2 April 2015|website=Earthobservatory.nasa.gov|access-date=22 January 2017|archive-date=2 February 2017|archive-url=https://web.archive.org/web/20170202012127/http://earthobservatory.nasa.gov/IOTD/view.php?id=88271|url-status=live}}</ref>
