M7 Outer Ring Road-Naas
||Could open : 2030||Status : Planned|
The N7 between Dublin and Naas, known locally as the Naas Dual Carriageway, was extensively upgraded in 2006. It was widened to 6 lanes and had 4 new junctions added. Most local access was also closed off. However, the job was not completed, with quite a number of such accesses still remaining. Considering this is such an important road, with such high traffic volumes and so close to Dublin, it is imperative that the section is eventually upgraded to motorway.
It is odd that the N7 runs from the M50 to Naas as a 6-lane grade separated dual carriageway, and the motorway only begins south of that along a winding route with poorer sightlines and width than the dual carriageway. Of course, the motorway at Naas should be widened too, but the non-motorway part is in need of significant enhancement. A large number of alterations would be necessary to bring the motorway standard from Naas as far as the R136 Outer Ring Road. Further in from there, although the whole road was grade separated by early 2015 with the opening of the Newlands Cross junction, there is still frontage, bicycle and pedestrian access, as well as bus lanes and bus stops. The main work required to achieve an upgrade of Naas-Outer Ring would be completion of frontage roads to the north and south which currently only run from Naas to Blackhill. This map indicates the route of the southern parallel road. Between Blackhill and the Outer Ring Road, the road is missing, as is nearly all of its northern counterpart. Although it is possible to continue using an existing road, this is a very narrow profile country lane and completely unsuitable for the purpose.
A lot of changes would be needed to implement this N7 upgrade:
- Widening of the road from Blackhill to Rathcoole. The road was pieced together from country lanes;
The South County Dublin Draft Development Plan 2010-2016 mentions these last two. The Tootenhill interchange will be known as Keating's Park and is item 61 on page 271. Only the northbound onramp of the Citywest interchange will be modified, however.
In the below map, yellow roads are regional (not part of the proposed motorway), blue indicates the route of the motorway and new ramps and other proposed parts of it, and red indicates access closures. Down to the southwest, the segment of existing motorway proposed to be widened to 6 lanes is shown in purple.
