R810 road (Ireland)
The R810 road is a regional road in south Dublin, Ireland connecting Cornmarket to the Naas Road (N7).
It begins near the Coombe and goes west until it becomes Tyrconnell Road, when it turns southwest. Shortly afterwards, when it crosses the Grand Canal, it becomes the Naas Road and continues southwest to the M50 motorway, at the Red Cow interchange, where it becomes the N7.
The official definition of the R810 from the Roads Act 1993 (Classification of Regional Roads) Order 2006 states:
The road is 7.3 kilometres (4.5 mi) long.

2+2 road
A 2+2 road is a specific type of dual-carriageway being built in Ireland and in Sweden and in Finland, consisting of two lanes in each direction separated by a steel cable barrier.
These roads do not have hard shoulders and therefore they cannot be designated as Motorway at some future date. The Irish variant,however, has 3.5m lanes where there are a number of Swedish variants some with 3.25m wide lanes.
Junctions are generally 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 Dublin to Sligo.
