Explanation:

The Inca Empire Road System was the extensive and advanced road network of the Inca Empire that collapsed in the 16th century in western South America, between the Andes Mountains and the Pacific Coast. There were a total of 40,000 kilometers of roads in the network.

The Incas built it centuries before the Spanish conquest. The network was partly based on pre-Inca roads. The network grew to its fullest size in the 15th century after the Inca Empire had reached its largest size.  

The road network connected the villages and towns of the vast Inca Empire, which therefore were located along the main roads. There were a total of 40,000 kilometers of roads on the Inca Empire Road System. It had two north-south main roads: the coastal highway and the mountain highway. There were inns every 20 kilometers; some of them were fortifications with military supplies.
