Limited-access road in the context of "Amphibious ATV"

In the field of road transport, an interchange (American English) or a grade-separated junction (British English) is a road junction that uses grade separations to allow for the movement of traffic between two or more roadways or highways, using a system of interconnecting roadways to permit traffic on at least one of the routes to pass through the junction without interruption from crossing traffic streams. It differs from a standard intersection, where roads cross at grade. Interchanges are almost always used when at least one road is a controlled-access highway (freeway) or a limited-access highway (expressway), though they are sometimes used at junctions between surface streets.

An arterial road or arterial thoroughfare is a high-capacity urban road that sits below highways on the road hierarchy in terms of traffic flow and speed. The primary function of an arterial road is to deliver traffic from collector roads to highways or expressways, and between urban hubs at a relatively high level of service. Therefore, many arteries are limited-access roads or feature restrictions on private access. Because of their relatively high accessibility, many major roads face large amounts of land use and urban development, making them significant urban places.

In traffic engineering hierarchy, an arterial road delivers traffic between collector roads and highways. For new arterial roads, intersections are often reduced to increase traffic flow. In California, arterial roads are usually spaced every half mile, and have intersecting collector(s) and streets.

A rest area is a public facility located next to a large thoroughfare such as a motorway, expressway, or highway, at which drivers and passengers can rest, eat, or refuel without exiting onto secondary roads. Other names include motorway service area (UK), services (UK), travel plaza, rest stop, service area, rest and service area (RSA), resto, service plaza, lay-by, and service centre. Facilities may include park-like areas, fuel stations, public toilets, water fountains, restaurants, and dump and fill stations for caravans and motorhomes.

A rest area with limited to no public facilities is a lay-by, scenic area, or scenic overlook. Along some highways and roads are services known as wayside parks, roadside parks, or picnic areas.

A shoulder (American English), hard shoulder (British English) or breakdown lane (Australian English) is an emergency stopping lane by the verge on the outer side of a road or motorway. Many wider freeways, or expressways elsewhere have shoulders on both sides of each directional carriageway—in the median, as well as at the outer edges of the road, for additional safety. Shoulders are not intended for use by through traffic, although there are exceptions.

The International E-road network is a numbering system for roads in Europe, Central Asia and Asia Minor, developed by the United Nations Economic Commission for Europe (UNECE). The network is numbered from E1 up and signposted on a green background. Its roads cross national borders, consisting of three types of roads: highways, limited access roads, and ordinary roads (as defined by ECE/TRANS/SC.1/2016/3/Rev.1).

The display of European roads on signs depend on jurisdiction. In most countries, the roads carry the European route designation alongside national designations. However, Belgium, Denmark, Norway and Sweden have integrated them as their sole route designations (examples: E18 and E6) in most cases. Some places, such as the United Kingdom and Albania do not show the European designations at all.

The Natchez Trace Parkway is a limited-access national parkway in the Southeastern United States that commemorates the historic Natchez Trace and preserves sections of that original trail. Its central feature is a two-lane road that extends 444 miles (715 km) from Natchez, Mississippi, to Nashville, Tennessee. Access to the parkway is limited, with more than 50 access points in Mississippi, Alabama, and Tennessee. The southern end of the route is in Natchez at its intersection with Liberty Road, and the northern end is northeast of Fairview, Tennessee, in the suburban community of Pasquo, at an intersection with Tennessee State Route 100. In addition to Natchez and Nashville, larger cities along the route include Jackson and Tupelo, Mississippi, and Florence, Alabama.

A frontage road (also known as an access road, outer road, service road, feeder road, or parallel road) is a local road running parallel to a higher-speed, limited-access road. Where parallel high-speed roads are provided as part of a major highway, these are also known as local lanes. Sometimes a similar arrangement is used for city roads; for example, the collector portion of Commonwealth Avenue in Boston, U.S., is known as a carriage road.

A frontage road is often used to provide access to private driveways, shops, houses, industries or farms that would otherwise be cut off by a limited-access road. This can prevent the commercial disruption of an urban area that the freeway traverses or allow commercial development of bordering property.
