Pan-American Highway

According to most sources, the longest road on planet Earth is the Pan-American Highway. It connects South and North America andstretches for 30,000 kilometers.

The Pan-American Highway begins in Alaska, in the oil town of Prudhoe Bay. While driving along it, people pass through many climatic and ecological regions. For example, for several kilometers a car can be surrounded by deserts, and then by dense jungles and even mountain passes. Traveling along the Pan-American Highway, people can see Canada, Chile, Bolivia, Costa Rica and many other countries. The road ends in the southernmost regions of South America.

The idea of ​​building a Pan-American Highway first appeared in 1923. According to the official version, the authors of the project wanted to unite several countries with this route. But there is also a version that with the help of this route the United States wanted to increase sales of American cars – it is much easier to supply them to Latin America.

The construction of the Pan-American Highway turned out to be a very long process, which was expected. Even in 1970, the road was not completely built, and even today it is not complete.

This area is located in the jungle and there is no road. The reason for this was that local residents protested, fearing for the safety of their culture. In particular, they feared the destruction of national parks. On top of all this, this area is still a very dangerous place. The fact is that it is often visited by members of dangerous groups and drug dealers. So, maybe it’s good that there is no road for cars in the Darya Gap.
