Blue Line

The Blue Line is a prominent border or boundary marker used in various contexts, most notably in urban transit systems like the Los Angeles Metro or Washington D.C. subway maps, where it represents a specific transit route. In general, it indicates a designated pathway or boundary identified by a blue-colored line for easy recognition, guiding people along a particular route or marking an edge. Its purpose is to clarify navigation or demarcate areas, making complex information simpler to understand through visual cues.
