A divided, controlled-access highway for through traffic is a _________________

A divided, controlled-access highway for through traffic is accurately termed a freeway. Freeways are specifically designed to allow high-speed vehicular traffic with minimal interruptions. They are characterized by features such as multiple lanes in each direction, no intersections or traffic signals, and access control, which means that vehicles can only enter or exit at designated interchanges. This design supports efficient movement and reduces the likelihood of accidents that are more common in roads with frequent intersections.

In contrast, an expressway, while similar to a freeway and sometimes used interchangeably, may allow for certain at-grade intersections and can have fewer restrictions on access. An avenue typically refers to a city street or roadway with various types of traffic, which does not fit the definition of a controlled-access highway. A turnpike is a toll road, which may be a type of freeway but is specifically used for highways that require a toll for access. Thus, the most accurate description for a divided, controlled-access highway meant primarily for through traffic is indeed a freeway.
