Question

what techniques did the inca use to build the inca roads?

Answer 1

The Inca road system was the most extensive and advanced transportation system in pre-Columbian South America. It was about 39,900 kilometres (24,800 mi) long.[1]:242 The construction of the roads required a large expenditure of time and effort.[2]:634 The network was based on two north-south roads with numerous branches.[3] The best known portion of the road system is the Inca Trail to Machu Picchu. Part of the road network was built by cultures that precede the Inca Empire, notably the Wari culture. During the Spanish colonial era, parts of the road system were given the status of Camino Real. In 2014 the road system became a UNESCO World Heritage Site.[4] Hope you like my answer

Answer 2

Answer:

Inca roads were built without the benefit of sophisticated surveying equipment using only wooden, stone, and bronze tools. As they were built in different geographical zones using local populations, the roads are, consequently, not uniform in construction design or materials.
