linear structure
An elevated construction extending along a route, with potential length limited by need and available land or water.
A linear structure is an elevated construction whose potential length is limited only by constraints of necessity and by the extent of land or water over which it is built.
The construction follows a line rather than occupying a compact site. Its potential extent is tied to the route it serves.
A road shelter extends along the route it protects. The route-following structure is distinct from a general network of roads or railways.
