Top 10 Regions with the Most Roads Above 5,000 Meters

Lifelines at the Peak of the World

In these regions, roads represent the ultimate challenge of human engineering. The Tibetan Plateau dominates the list, particularly in the Ngari and Nagqu prefectures, which feature numerous 'roads in the clouds' built for border patrol, mineral transport, and high-altitude tourism.

• Key Fact: The highest permanent road passes globally are concentrated here; many sections are snow-covered year-round, with oxygen levels below 50% of sea level.
• Data Comparison: Compared to the Andes, the roads above 5,000m on the Tibetan Plateau exhibit higher density and a more connected network structure.
