In the Inca civilization, all roads led through what?

Explanation:

Inca roads covered over 40,000 km (25,000 miles), principally in two main highways running north to south across the Inca Empire, which eventually spread over ancient Peru, Ecuador, Chile, Bolivia, and Argentina. One highway ran down the coast, and the other wound through the highlands. Another important route ran east from Quito (Ecuador) across to Mendoza (Argentina), and there was also a major route along the plains of the northern coast. Criss-crossing these main roads were some 20 other secondary routes and many smaller trails besides. Roads were also built which went beyond Inca-controlled settlements and led to outside territory, perhaps to facilitate trade with, or military operations against, neighbouring peoples. Along some of the more important highways, milestones marked each Inca unit of distance.
