The road crosses the R761 at a roundabout near Eden Gate and terminates at the R762 north of Charlesland, Greystones.
It was completed in 2004 but not connected to the N11 until June 2006, via a temporary "left-in, left-out" junction. The construction of a full grade interchange between the R774 and N11 was delayed when an illegal dump was unearthed at the original location for the junction.
Construction of the permanent fully grade-separated junction (J11 on the N11) started in October 2006 and was completed in 2008.
A distinctive feature of this road is the pink central barrier (see thumbnail); it may be the only coloured barrier in Ireland.
