Some of the route is the original route of the N7 road prior to the construction of the Chapelizod bypass on the N4, at which point N7 traffic was redirected to use the M50 motorway and N4 road instead to travel between Dublin city centre and the Red Cow roundabout. It is therefore the alternative route for motorway prohibited traffic for this section of the N7.
