All You Need To Know About This Road

It is quite fascinating that the Pan-American Highway isn’t a new infrastructure project! In fact, its construction began in the early 1920s. The aim was to boost tourism in the United States. In 1937, the 14 countries signed an agreement to develop their sections of roads to create a continuous route. By 1960, the Pan-American Highway was officially open for public use.

The longest road in the world also has the straightest path. Reportedly, the Pan-American Highway lacks significant turns or U-turns for thousands of kilometres. If one travels 500 kilometres daily, it will take a little more than 60 days to traverse the entire route. However, it also depends on your travel speed and how many stops you take. One of the travellers, named Carlos Santamaría, took around 117 days to complete a journey on this route.

There is one obstacle on this great journey – the Darién Gap. It is a 100-kilometre stretch of dense jungle and swamp. Due to concerns over potential harm to ecosystems and Indigenous communities, the road was never built in this area between Panama and Colombia. To bridge the gap between this sole interruption in the Pan-American Highway, travellers often transport their vehicles from Panama to Colombia and fly separately to continue their journey.
