Bridges

 In general, there are two types of gangways, which may be used separately or combined;

• Articulated gangways, these are the most common gangways. One side of the gangway is connected to the shore by means of a hinge that is securely fastened to a quay wall or earth anchor. The other side rests on the floating structure and moves along with the tide or fluctuations of the water level.
  
  
• Elevated gangways, mostly used where the floating structure is farther away from shore. The bridge or gangway will be placed over one or more piles before descending to the floating structure or the other side of the crossing.

All gangways are designed to its use, but generally they are made up to 30 meters long and 3 meters wide. Larger gangways are certainly no exception but require individual designs and calculations.
