Tay Lane Junction on N7

Because of safety concerns at the Tay Lane Junction on the N7 a number of options have been examined with regard to improving the junction.  The matter has been discussed at length at the Area Committee and a number of consultation meetings have been held with local residents and occupiers of the industrial estate which were attended by local representatives.  No direct funding is available from the National Roads Authority to undertake works.

TAY LANE OPTIONS  in order of Cost

OPTION  1 :   Closure of Junction,  Divert traffic to Rathcoole Interchange.  Simplest, safest and cheapest option.   Minimum cost involved  order of  €50000, It should be noted that we have spent close to this amount already in repair of the rope barrier et al.

OPTION  2 :    Close Tay lane to Inbound traffic and allow for exit only,

This will involve the removal of traffic island and rope barrier from the main line carriageway and relocating same on the outside of the exit lane from Tay Lane to prevent direct access to the main line except at the Interchange as well as modifications to the footpath, drainage and blacktop . Estimated cost  €800000-€1.0 million. 

 Shown coloured yellow on attached map.

OPTION 3 :  The preferred option to leave the junction open which is a combination of Option 2 and the provision of a separate lane to connect to Tay lane behind the footbridge thus separating the In and Out approaches to Tay lane.  This also involves the purchase of land and the demolition of an inhabited house at an estimated cost of €3.0 million in total.

Shown coloured yellow and purple on attached map.

It should be noted that the provision of a new left in can only be located at the position shown on the drawing in order to ensure safety of access to and from properties on Tay lane. Any alterations to the Footbridge will mean that totally new ramps (wider and longer) would be required to meet current Disability specifications and ability to withstand traffic impact greater than currently in place. 

The present situation cannot be allowed to continue indefinitely and it will be necessary to close the junction on safety grounds with the situation being reviewed should financial resources become available to undertake the necessary work.
