An elevated highway is a type of roadway that has been built on top of supporting structures, such as pillars or embankments, in order to raise it above ground level. This allows for traffic to flow unimpeded by obstacles and intersections below, resulting in smoother and faster travel. Elevated highways are commonly used in urban areas where space is limited, but they can also be found in rural settings as well. The term "elevated" refers specifically to the raised position of the roadway itself, rather than any other type of infrastructure or support system that may accompany it.
