An example of a 2+2 dual-carriageway in Ireland (the N4)
A 2+2 road is a specific type of dual-carriageway being built in Irelandmarker and Swedenmarker, consisting of two lanes in each direction separated with a steel cable barrier. They do not have hard shoulder. Junctions are at-grade roundabouts and minor roads cross under or over the mainline without connecting. They are also known as "Type 2 dual-carriageways" by the Irish National Roads Authority. These roads look similar to expressways, except that expressways often have interchanges, large medians or concrete barriers between traffic. The United States has 80,000 km of roads that fit this description .

First 2+2

The first road of this type opened in December 2007 as a new greenfield section of the N4 national primary route which joins Dublinmarker to Sligomarker.
