What is a key characteristic of an expressway?

A key characteristic of an expressway is that it typically has a median separating opposing lanes of traffic. This design feature enhances safety by reducing the likelihood of head-on collisions and allows for smoother flow of vehicles traveling in opposite directions. The median can be a physical barrier or a wide space that serves to guide traffic safely and reduce distractions between lanes.

In contrast, expressways are designed for higher speed travel with limited access points, which helps to streamline traffic. The presence of cross traffic, no speed limits, or usage primarily for local traffic would not align with the primary function and design characteristics of an expressway. Expressways are engineered to facilitate efficient long-distance travel, accommodating faster speeds while minimizing stops and disruptions.
