What is the key difference between expressways and freeways?

• A. Tolls are required on expressways, but not on freeways
• B. Both are identical in design
• C. Freeways have traffic signals; expressways do not
• D. Expressways feature intersections; freeways use interchanges

Answer: (D)

The key idea is how access to other roads is controlled. Freeways are designed for continuous, high‑speed travel with no at‑grade crossings, so entering or exiting happens only through ramps that connect to a system of interchanges. Expressways allow more direct access points and can have intersections with cross streets, which may be at the same level or with signals. That difference—interchanges for freeways versus intersections on expressways—is what sets them apart. Tolls aren’t a defining factor—some freeways and expressways are tolled, while others aren’t. Saying they’re identical in design isn’t accurate, since the presence of at‑grade intersections versus grade‑separated interchanges changes how traffic flows. The claim about signals on freeways isn’t universally true, whereas the core distinction is the access method: intersections on expressways versus interchanges on freeways.
