The Porterstown Link Road

Note: this road is now open and there have been some delays at the traffic lights. At my request the lights were tweaked this morning (April 19th) and will be kept under review for the next few weeks. 

The original plans were for the roundabout to remain. However, given that a secondary school and possibly two primary schools will be accessed from the junction, it was decided that traffic lights would provide more safety for pedestrians.

The old Porterstown road will now be closed to vehicular traffic at the railway crossing so all traffic between the new road and the Clonsilla road will have to travel over the Dr. Troy Bridge.

The junction of the Luttrellstown road and the Lucan/Clonsilla road at the main gates to luttrellstown Castle will be changed to give priority to Luttrellstown/Lucan traffic and effectively making the road to the Clonsilla rail crossing a side road.

 
The County Council at it’s meeting in July adopted and approved the scheme for the construction of the Porterstown Link Road from the Diswellstown Road Roundabout to the Luttrellstown Road at it’s existing junction with the Porterstown Road. This new road will help reduce traffic flows on the Clonsilla road as N4/N3 traffic from Lucan seek to avoid delays at the Clonsilla level crossing.
The Scheme also includes

(a) the construction of a new road from Diswellstown Road Roundabout to Porterstown Road together with grass verges, pedestrian footpaths and cycletracks;

(b) construction of a new road between Diswellstown Roundabout and Luttrellstown Road to the Porterstown Road at a point approximately 150 metres south of the existing Diswellstown Roundabout/
