A
limited-access road, known by various terms worldwide, including
limited-access highway,
dual-carriageway,
expressway, and
partial controlled access highway is a
highway or
arterial road for high-speed traffic which has many or most characteristics of a
controlled-access highway (freeway or motorway), including limited or no access to adjacent property, some degree of
separation of opposing traffic flow, use of
grade separated interchanges to some extent, prohibition of some modes of transport such as
bicycles or
horses and very few or no intersecting cross-streets. The degree of isolation from local traffic allowed varies between
countries and regions. The precise definition of these terms varies by jurisdiction.
