What culture developed 10000 miles of roads and rope bridges?

The Inca civilization, which thrived in South America from the early 15th century until the Spanish conquest in the 16th century, developed an extensive network of approximately 10,000 miles of roads and rope bridges. This sophisticated infrastructure was crucial for connecting their vast empire, facilitating trade, communication, and military movement across diverse terrains. The roads were primarily made of stone and dirt, while the rope bridges, made from natural fibers, allowed for safe passage over deep canyons and rivers. The Inca's engineering prowess significantly contributed to their ability to govern and unify their territories.
