An expressway is characterized by partial control of access, which means that certain access points are limited or controlled, allowing for higher-speed travel while still providing connections to other roads and areas. This type of highway typically has grade-separated intersections, on-ramps, and off-ramps, enabling vehicles to enter and exit without stopping the flow of traffic.

In contrast, freeways represent a situation of full control of access, where no at-grade crossings or direct property access is permitted, resulting in uninterrupted traffic flow. Local roads, on the other hand, provide direct access to buildings and neighborhoods, leading to lower speeds and more frequent stops. Congested highways can occur in various forms, but they do not specifically describe the access control features that define an expressway.

Understanding the characteristics of an expressway is crucial, as it plays a vital role in facilitating efficient transportation while balancing accessibility needs.
