All Roads, Highways and Trade Routes

Road networks and historic overland trade routes engineered or established to move people and goods across long distances, from ancient royal roads and trade corridors through the modern national highway system. Belongs here: named ancient and historic roads, modern highway systems and long-distance overland trade routes considered as a physical corridor. Does not belong here: named services that operate along a route, tracked as route-service entities, or maritime trade routes, grouped separately under a future maritime corridor bucket once the atlas mints enough of them.
