2200-Year-Old 'Super Highway' Unearthed in China, Astonishes Modern Engineers

• Archaeologists in Yulin city, Shaanxi province, China, discovered a 13-kilometer section of the 2200-year-old Qin Straight Road, a 'Super Highway'.
• The road, estimated to be 900 kilometers long, was built by Emperor Qin Shi Huang primarily for military purposes against northern nomads like the Xiongnu.
• Its engineering is remarkable: 40-60 meters wide (like a 4-lane highway), cut through mountains, filled valleys, and constructed using 'rammed earth' technique.
• Discovered using historical documents and satellite images, the road was continuously used from the Qin Dynasty to the Han Dynasty.
• Described as China's second-largest national defense project after the Great Wall, it's considered an ancestor of modern highway systems.

Why It Matters: Ancient China's 2200-year-old 'Super Highway' proves visionary human engineering without modern tech.
