Foxrock residents have held a meeting amid concerns that a main road will be closed for the summer so a sewer pipe can be laid.
Locals said they were perplexed when signs went up in the area indicating that a private developer was seeking permission to have Brighton Road shut to traffic from June 13 to September 2.
They said they could not see why such a long section of road needed to be closed for such a long period of time to lay a 150-metre-long sewer.
At a meeting held in the local Gables restaurant, residents and councillors sought clarification from Dun Laoghaire-Rathdown County Council and Castlethorn developers on the issue. The Herald was asked to leave the meeting as it proceeded.
Castlethorn has lodged an application with the council to close Brighton Road to through traffic from the junction with Westminster Road to the junction of Claremont Hall - a distance of nearly 1.5km.
"The purpose of the road closure is to facilitate the laying of a new sewer pipe from the entrance of the Hollybrook apartments south for a distance of approximately 150 metres to service a new housing development along Brighton Road," the road closure application reads.
It is proposed that during the closure, diversions would be in place using Westminster Road, Hainault Road and Claremont Road.
After the meeting, locals said most of the issues of concern had been clarified and the council and developer would work with the local community to keep disruption to a minimum.
"We were pleased with the progress at the meeting and we got clarification on the road closure. There will still be local access to homes and businesses, but through traffic will be diverted," said Sheila Moore, secretary of the Foxrock Area Community and Enterprise Committee.
A council spokesman said that the closure of the road had to be more extensive than the work area in order to facilitate the implementation of an efficient detour.
