Proposed Temporary Closure of Mount Merrion Avenue

Friday, October 22, 2021
Intro Text 

Dún Laoghaire-Rathdown County Council has received an application from Roadstone on behalf of Transport Infrastructure Ireland (TII) to temporarily close Mount Merrion Avenue from the junction with Rock Road to the junction with Cross Avenue.

A Traffic Management Plan will be in operation and local access will be maintained at all times. Diversion routes will be clearly signposted.

Any interested parties may lodge an objection in writing with the Senior Engineer, Traffic Section, County Hall, Marine Road, Dún Laoghaire not later than noon on Thursday 4th November 2021 or email

It is proposed that the closure take place between 7:30 pm and 5:30 am from Tuesday 23rd November 2021 to Sunday 5th December 2021. The purpose of the closure is to facilitate plaining and line marking works. These works will take place at night because of high traffic volumes during the day.
