Linkspan

A linkspan or link-span is a type of drawbridge used mainly in the operation of moving vehicles on and off a RO-RO vessel or ferry, particularly to allow for tidal changes in water level.

Linkspans are usually found at ferry terminals where a vessel uses a combination of ramps either at the stern, bow or side (or a combination of any) to load or unload cars, vans, trucks and buses onto the shore, or alternately at the stern and/or the bow to load or unload railroad cars.
