What is a bypass in road terminology?

In road terminology, a bypass refers to a roadway constructed to divert traffic away from a congested area, such as a city or town, in order to improve traffic flow and reduce congestion on local streets. The correct answer relates more closely to the concept of a bypass being a route specifically designed to go around a certain area rather than being defined by its even-numbered routes or having specific intersections.

While other options mention specific characteristics of roads, they do not align with the definition of a bypass. A bypass is primarily about creating an alternate route to facilitate smoother travel and lessen delays in traffic. This designation focuses not on the type of intersections, numbering systems of routes, or scenic quality, but rather on the functional purpose of improving traffic flow by providing an alternative path around busy areas.
