A [[limited-access road]], oftenalso calledknown aas limited-access highway (US),in dividedthe highway (US), or dual carriageway (UK),U.S. and in some situations anas [[controlled-access highway|expressway]] in numerous countries (including parts of the U.S.), is similar to a controlled-access highway in that it conforms to many or most of the standards that controlled-access highways follow, but does allow some uncontrolled access to local roads. They can be viewed as a middle ground between controlled-access highways and minor arterial roads. The degree of isolation from local traffic varies between countries and regions, as does a precise definition of the term itself.
Controlled-access highways can also be viewed as a subset of limited-access highways that has stricter requirements.
