context_page_description: 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, 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 cars, 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.
context_section_description: A High-quality dual carriageway (HQDC) in Ireland is normally completed to a motorway standard, including no right-turns, but with no motorway restrictions. These are common on the final stretches of motorways nearing a major city, generally in order to enable use of bus stops and city bus services on the particular stretch of road.
  There are not yet any specific signs for this type of road, but the National Roads Authority have hinted that they are looking at implementing the German-style Autostrasse sign in Ireland.
  Speed limits are normally 100 km/h compared to 120 km/h on motorways
