Instead of having an abstract class defines the interface to the abstraction and its concrete subclasses implement it in different ways all in one class hierarchy, bridge pattern separates implementation from domain abstraction so they can be reused or extended independently with respect to its own inheritance hierarchy. Simple Beam Bridges - On short spans (8m, 10m, 15m and then more expensively up to 24m), bridges can be made from a number of beams under the roadway straight across the gap. For example, a H15-44 is a 15-ton truck as reported in the 1944 specifications. Author(s) Michael A.
