the 106 kilometers of jungle that no country has been able to pave

If you like driving, throughout the planet there are some roads so legendary that they invite you to travel them at least once in your life. This is the case of the iconic Route 66 that crosses the United States from Chicago to Los Angeles, the beautiful and curvy Romanian Transfăgărășan or the dangerous Highway of Death in Bolivia. But if you have time and you are in America, there is one to explore the continent practically from start to finish: the Pan-American route. The longest road in the world. The Pan-American Highway It has a length of 17,848 kilometers, which allows it to travel across the American continent from north to south: from Prudhoe Bay in Alaska to Ushuaia, Tierra del Fuego in Argentina. Of course, the figure corresponds only to the main road, but in reality it is a multitude of roads in different countries and characteristics, so that they adapt their layout to areas such as large cities, the coast or the mountains. If we add the variants and branches, it shoots up to 30,000 kilometers, although the Guinness says simply that it is more than 24,140 kilometers through the 14 countries it crosses. The origins. Although originally was glimpsed like a pan-american railroad, at the Fifth International Conference of American States 1923 when the idea took shape like a highway, given the takeoff of the automobile. However, it would take decades for it to materialize: it was at the Convention on the Pan-American Highway when the 14 countries signed the agreement and Mexico the first country to complete its partback in 1950. To choose which route was the best, the “Brazilian Pan-American Highway Expedition” was a pioneer in the task of traveling the continent choosing the most practical route. Lieutenant Leônidas Borges de Oliveira as mission leader, Francisco Lopes da Cruz as observer and Mário Fava as mechanic left Rio de Janeiro on April 16, 1928 with two Model T Fords and arrived in Washington DC ten years later. In figures. Only those 17,848 kilometers of length of its main road already make it the longest route, followed by others such as transsiberian highway (it only runs through Russia and is about 11,000 kilometers) or the Highway 1 Australian 14,500 kilometres. But there are more impressive figures: It travels through 14 countries and connects 10 state capitals. There is only an incomplete section of 106 kilometers. 23 days, 22 hours and 43 minutes is the record time to travel it by car, which is registered in the Guinness Book of World Records. If you drive 8 hours a day, it doesn’t add up Its highest point is in Costa Rica Hill of Deathat about 3,500 meters high. The exception: the Darien plug. Although the Pan-American Highway runs through America from top to bottom, technically this is not the case: there is a hole in the border between Panama and Colombia, the Darién Gap. This jump on the road is in a mountainous and rugged area in the middle of the jungle. That is, the highway ends in Turbo (Colombia) on one side and in Yaviza (Panama) on the other. Mountains, swamps and a dense jungle have been a compelling orographic reason why you cannot cross America continuously by car without leaving that road. However, there have also been environmental and political problems that have prevented the closure of the route. In 1971, the United States, Colombia and Panama they agreed cover this route and their respective economic contributions. However, after environmental protests and a correction in the cost estimate that practically doubled it, the project was stopped. Today there are no active plans to close the Pan-American Highway. A road full of challenges. This environmental wealth reveals a reality, that of the confrontation between the development of infrastructure and the conservation of the environment, as it passes through unique landscapes. Along its route, the Panamericana crosses tropical jungles, the Andes mountain range, deserts or seismic zones that mean that this was not just another highway construction. Access or weather conditions are a challenge for machinery, personnel and materials. And once built, there is the challenge of maintaining a road network across different countries, budgets and standards.

The agreement with the US seemed to pave the way to Nvidia in China. Now is the Asian giant who begins to close the door

The agreement with Washington had allowed Nvidia sell again Your H20 chip In China. It was a door that opened after months of restrictions. Now, the Chinese authorities have begun to close it slowly: According to Financial Timesand Reutersthey have summoned Alibaba, Bytedance, Tencent and other companies to explain why they buy H20 instead of using local processors. The gesture is not symbolic, several of them are rethinking their orders, and the new scrutiny comes while Beijing encourages a prioritize domestic alternatives. Nvidia developed the H20 in direct response to the export limitations that the United States imposed at the end of 2023. For a time it was its star product for Chinese clients, until this year it was again blocked by a new Washington decision. In July 2025, the veto rose after an agreement with the Trump administration for Nvidia would transfer 15% of the income of some advanced chip sales in Chinaaccording to Reuters. That turn reopened the door, but also unleashed criticism in the United States for its supposed impact on China’s capabilities. A historical agreement that now faces resistance Authorities such as the Ministry of Industry and Information Technology, Mits, people aware of the situation, and the administration of the cyberspace of China, CAC, according to Reuters, have held meetings with companies such as Alibaba, Bytedance, Tencent and Baidu. They have asked them Why don’t they turn to national alternatives and have expressed their disapproval for the use of H20 in government or security areas. They have also raised doubts about the information that Nvidia asks to send to Washington for review. As a result, several companies have begun to reconsider their orders, according to Financial Times, although Reuters points out that it was not ordered to stop shopping. Concerns are not limited to preference for local chips. The Internet regulator asked NVIDIA to clarify whether H20 could involve risks for Chinese user data, including the possibility of “backdoors.” In this sense, Beijing has expressed concern for functions such as remote shutdown or location tracking. Nvidia, as we have seen before, He denies these capacities and argues that H20 is not a military product or for government infrastructure. According to Financial Times, Huawei, Cambricon and other Chinese manufacturers have increased their presence in the market since the H20 was subject to restrictions. Beijing has reinforced the message of technological self -sufficiency and encourage large platforms to opt for local suppliers. Now, it is no secret that the lack of access to advanced manufacturing equipment, Like the latest generation lithography, it is still an obstacle. Despite this, the demand for national chips grows thanks to political support and the need to reduce external dependence. But not everything plays in favor of the local giant Huawei. Great Chinese technology, such as Tencent, Alibaba or Bytedance, continue to prefer Nvidia GPUs For its greatest performance and, above all, by CUDA, the parallel programming platform of NVIDIA that allows the most of its GPU for artificial intelligence and other complex calculations. Replacing it with alternatives such as Cann implies overcoming technical and compatibility barriers. Li Guojie, from the Chinese Academy of Sciences, warns that China needs its own tools that exceed Cuda to achieve self -sufficiency. The great Chinese technology, such as Tencent, Alibaba or Bytedance, continue to prefer Nvidia GPUs. Bernstein, collect ftestimates that the market share of Nvidia in China will go from 66% in 2024 to 55% this year. In parallel, Trump has suggested that he could authorize a Limited version of Blackwell -based processorsthe most advanced of the company. In any case, Nvidia generated 17,000 million dollars in sales in China in its last year13% of its total income. In this environment, each regulatory decision weighs as much as the technological road map itself. What in July was presented as an advance for Nvidia has become an uncertain scenario. Beijing’s pressure, added to the impulse to national manufacturers, redefines the company’s possibilities in a market that was strategic for years. According to the aforementioned means, the outcome will mark not only the future of Nvidia in China, but also the way in which both powers manage artificial intelligence when politics, security and trade intersect.
