United States Freeways
Interstate 80 (Eastshore Freeway) in Berkeley, a typical American freeway
In the United States of America, a freeway is a divided highway with full control of access. This means two things. First, adjoining property owners do not have a legal right of access, meaning that they cannot connect their lands to the highway by constructing driveways. When an existing road is converted into a freeway, all existing driveways must be removed and access to adjacent private lands must be blocked with fences or walls. Second, traffic on the highway is “free-flowing”, although many non-engineers misapprehend the “free” in “freeway” to mean that such a highway must be free of charge to use. All cross-traffic (and left-turning traffic) has been relegated to overpasses or underpasses, so that there are no traffic conflicts on the main line of the highway which must be regulated by a traffic light, stop signs, or other traffic control devices. Achieving such free flow requires the construction of many bridges, tunnels, and ramp systems. The advantage of grade-separated interchanges is that freeway drivers can almost always maintain their speed at junctions since they do not need to yield to crossing traffic.
Expressways
In contrast, an expressway is defined as a divided highway with partial control of access. Expressways may have driveways connecting to adjacent properties, although the trend over time has been to minimize driveways when possible. Expressways also may have at-grade intersections, though these tend to be spaced farther apart than on most arterial roads. In urban areas, expressway intersections are usually controlled by traffic lights, but in many rural areas, cross-traffic is governed only by stop signs, and there are no restrictions on through traffic. Vehicles crossing an expressway at rural intersections must cross four lanes with vehicles coming at them at prevailing speeds. Thus, expressways are more dangerous than freeways and cannot carry traffic as efficiently as a freeway.

Highway is a term commonly used in the United States to designate major roads intended for travel by the public between important destinations, such as cities.
Highway designs vary widely. They can include some characteristics of freeways and motorways such as multiple lanes of traffic, a median between lanes of opposing traffic, and access control (ramps and grade separation). Highways can also be as simple as a two-lane, shoulderless road. The United States has the largest network of national highways, including Interstate highways and United States Numbered Highways. This network is present in every state and connects all major cities. China has the fastest expanding and second largest highway system in the world.
Some highways, like the Pan-American Highway or the European routes, connect multiple countries. Australia’s Highway 1 connects all state capitals and runs almost the entire way around the country.
The longest single national highway in the world is the Trans-Canada Highway, which runs from Victoria, British Columbia, on the Pacific Coast, through ten provinces to the Atlantic Coast, at St. John’s, Newfoundland.
Highways are not always continuous stretches of pavement. For example, some highways are interrupted by bodies of water, and ferry routes may serve as sections of the highway.
