Causeways, bridges, and tunnels

Borders relevant to this list may arguably include short theoretical borders in the middle of man-made constructions. A bridge does not constitute a land border; however the status of tunnels as "true" land borders is disputed, as these exist on land, but not on the surface. Also artificial islands or causeways could be disputed.
