Inca Road Network

Timeline

1. c. 1200–1370Urubamba Valley and Cusco Valley · CuscoThe Kingdom of Cusco built stone footpaths and pass routes around the capital, linking the sacred center with each ayllu community and extending along valleys to control neighboring peoples, forming early channels for military movement and tribute transport.
2. 1371–1380Cusco · CuscoIn the 1370s, relay stations, storage facilities, and checkpoints were added along kingdom roads, allowing the royal house to quickly levy local warriors and materiel from Cusco to counter pressure from neighboring powers such as the Chinchay; the roads' military mobilization function grew markedly in the kingdom's late period.
3. c. 1380–1438Central Andean highlands · PeruBy the late 14th century, the Kingdom of Cusco's roads had linked several key gorges and mountain passes, connecting with suspension bridges and stone stairways; this regional network provided a technical and organizational template for rapidly extending imperial trunk roads during Pachacuti's conquests in the 15th century.
