The Inca road system connected the three ecological zones of the Andes in a most effective way. It consisted of two north-south highways and about a dozen interconnectors. The coastal highway connected all fishing towns, the inland highway all major agricultural centres.
One of the four highways that leave Cuzco in the four major directions of the compass.
The highway to Machu Pichu climbs to 4,200 m above sea level. Today the 40 km distance from Qorihuayrachina is a famous 3 day tourist hike.
The mountainous terrain of the inland highway required many suspension bridges, which were built from fibre. The maintainance through reweaving was the responsibility of the neighbouring villages. Some Inca bridges are still in use today and maintained in the same way as under Inca rule.
