Infrastructure

The built works that make transport possible at scale: canals, bridges, tunnels, historic and continental railways, roads and highway systems, and pipelines, considered as engineering and operating history rather than as the vehicles that travel over them. Belongs here: any named canal, bridge, tunnel, historic railway, road system or pipeline whose construction, engineering or operating history is the reason for the entry. Does not belong here: the geographic feature an infrastructure work occupies, such as a strait or river, which belongs to the Geography atlas, or wars and political history tied to a route, which lean History; Transport keeps the built thing and its operating history.
