What identifies the primary purpose of an expressway?

The primary purpose of an expressway is to move large volumes of traffic efficiently and quickly over long distances. This type of road is designed to facilitate high-speed travel and minimize interruptions, which is why you typically find limited access points and fewer intersections. The design of expressways often includes features such as multiple lanes, controlled access ramps, and grade separations, all aimed at accommodating significant traffic flow and enhancing safety for motorists.

In contrast, while recreational routes can be found in some transportation systems, their function is not aligned with the purpose of expressways. Similarly, managing urban traffic and connecting local neighborhoods involves a different set of transportation strategies focused on accessibility and community connectivity, rather than the primary goal of efficiently transporting large volumes of traffic over extended distances.
