About Qhapaq Ñan – Andean Road System
The backbone of Tawantinsuyu, Qhapaq Ñan runs 6,000 km along the Andean crest from Colombia to Chile, with east–west transversal roads totalling over 23,000 km. Stone-paved with lateral drains, stairways, causeways across bofedales, and suspension bridges of braided ichu grass, it integrated the empire via chaski runners carrying quipu messages at 10 km/h and caravans of llamas. Tanpu tambos every 20–30 km stored chuno and chicha.
