Dublin–Belfast corridor

The Dublin–Belfast corridor^[1] (population 3.3 million) is a term used to loosely describe a geographical area that encompasses the Republic of Ireland's capital city, Dublin, and Northern Ireland's capital city, Belfast. It also includes the smaller cities of Lisburn and Newry; major towns such as Drogheda and Dundalk;^[2] and the Dublin satellite suburb of Swords.^[3] The term has been used in papers regarding planning strategies in the area, with the aim of capitalising on the expanding economies of both cities.^[4] Since the implementation of Brexit, the corridor exists inside the European Union on its Republic of Ireland side, and outside the European Union on its Northern Ireland side, but there is no so-called "hard border" between the two states.
