What is defined as a divided highway with full control of access and multiple lanes for traffic in each direction?

A divided highway with full control of access and multiple lanes for traffic in each direction is best defined as a freeway. This type of highway is designed for high-speed vehicular traffic and is characterized by features that improve safety and traffic flow, such as no intersections or traffic signals, limited entry and exit points, and usually no traffic crossing at the same level. These attributes are crucial for reducing the risk of accidents compared to regular roadways.

While an expressway often shares similar characteristics with a freeway, it may include at-grade intersections and is not always as strictly defined in terms of access control. The term motorway is commonly used in other countries, particularly in the UK, but it still refers to a similar concept. Interstate highways specifically refer to the U.S. national network of highways designed for long-distance travel, which often includes freeways, but not all interstates are freeways as they can vary in design and control features across different locations. Thus, the most precise term for this specific description is freeway.
