This may imply that over short separations bridges might be favored as opposed to tunnels .As expressed before, bridges may not permit ships to pass, so, for example, the Øresund Bridge have been developed to solve such problem.
Compared with ferry links
As with bridges, ferry links construction costs lower than tunnels.
