BridgeTower_P | Feature Type | A tower and/or pylon from which the deck of a bridge is suspended. | -

Bridge_C | Feature Type | A structure that connects two locations and provides for the passage of a transportation route (for example: a road or a railway) over a terrain obstacle (for example: a waterbody, a gully, and/or a road). | A bridge consists of a set of two abutments and/or zero or more bridge piers joined by bridge spans. A bridge may serve, for example, as an overpass or a viaduct. In the context of a bridge, the scope of the term 'transportation route' includes the transportation of liquids or gases by means of either pipelines or aqueducts.

CausewayStructure_C | Feature Type | A solid raised way across a terrain obstacle (for example: a wetland or a body of shallow water) that is intended to support a transportation route (for example: a road or a railway). | The causeway structure is often constructed from local fill supplemented by other materials (for example: rocks, boulders or gravel) and consists of a solid linear structure in the configuration of an embankment. Causeway structures are built just high enough to insure that the transportation route will remain passable during periods of flooding, tides and seasonal rainfall. Culverts may occur along the length of the causeway structure and individual sections of the causeway structure may be interrupted by bridges.

TransRouteProtectStruct_C | Feature Type | A structure built over and/or along a transportation route designed to prevent damage to, or blockage of, the route from rock slides, snow slides and/or weather phenomena. | For example, a snow shed, a rock shed or a gallery. These structures are usually located in rugged mountainous regions.

TunnelMouth_C | Feature Type | The opening of a tunnel into a larger space (for example: onto the terrain surface). | A tunnel is usually open to the terrain surface at both ends, but may sometimes lead to an enclosed space, for example: leading to an underground bunker, into an underground mine (termed an 'adit') or into an underground railway station.

Tunnel_C | Feature Type | An underground passage that is open at both ends and usually contains a land transportation route (for example: a road and/or a railway). | Commonly used to pass through a hill or mountain, or under a river or road. May also provide underground passage in a mine.

TurnaroundSite_C | Feature Type | A shaped area at the terminus of a road that provides sufficient turning space allowing incoming traffic to turn around and exit without performing a stop-and-change-direction manoeuvre. | Construction is typically in the form of a defined shape (for example: circle, loop, or crescent). A median-like structure may exist in the center of the turnaround site, thus ensuring a well-defined pattern of vehicle movement. In residential areas the turnaround site often has multiple adjoining properties, each of which may have a separate driveway and/or defined parking area along the perimeter of the shaped area.
