The bridge pattern is a design pattern used in software engineering that is meant to "decouple an abstraction from its implementation so that the two can vary independently", introduced by the Gang of Four. [1] The bridge uses encapsulation, aggregation, and can use inheritance to separate responsibilities into different classes.
Bridges (or overpasses, also called flyovers), tunnels (or underpasses), or a combination of both can be built at a junction to achieve the needed grade separation. In North America, a grade-separated junction may be referred to as a grade separation [1] [2] or as an interchange – in contrast with an intersection, at-grade, a diamond crossing ...
A grade-separated junction is a transport junction where at least one bridge or tunnel is used to separate traffic flows (known as grade separation). Relevant articles include: Road interchanges, known as grade-separated junctions in the UK; A flying junction, a type of grade-separated junction found on railway lines
The structure of an application with PAC. Presentation–abstraction–control (PAC) is a software architectural pattern.It is an interaction-oriented software architecture, and is somewhat similar to model–view–controller (MVC) in that it separates an interactive system into three types of components responsible for specific aspects of the application's functionality.
A pedestrian separation structure is any structure that removes pedestrians from a roadway, street or railway track. This creates a road junction where vehicles and pedestrians do not interact. This can be considered a type of grade separation structure on the road. These structures can be located either above the roadway or below the roadway.
The best explanation of the pattern I've seen was on youtube (Christopher Okhravi – Bridge Pattern – Design Patterns (ep 11)), but even then it just seemed like what you would naturally do rather than any special pattern. Which might be absolutely right; we might instinctively reach to code in ways that constitute a design pattern.

All these patterns solve some software problems common to many software development projects. These techniques have not been invented to create new ways of working, but to better document and standardize old, tried-and-tested programming principles in object-oriented design.
