Which term describes a highway with full control of access?

A highway with full control of access is described as a freeway. Freeways are designed to provide uninterrupted traffic flow, which means that vehicles enter and exit the roadway only at designated interchanges. This design limits the potential for conflict with other types of traffic, making it safer and allowing for higher speed travel without interruptions from intersections, traffic signals, or direct access to adjacent properties.

The characteristics of freeways include multiple lanes of traffic traveling in each direction, limited access points, and a separation of traffic moving in opposite directions, typically through physical barriers or medians. This creates a more efficient transportation route for long-distance and high-speed travel.

While terms like expressway and restricted access highway might also refer to controlled access roadways, they can have nuances that differ from the full control status of a freeway. An expressway may have some at-grade intersections or less stringent access control, whereas a restricted access highway might imply variations in access control that do not meet the strict criteria defining a freeway. Local roads, on the other hand, are typically designed for lower speeds and provide direct access to properties, making them fundamentally different from freeways.
