They’re being reduced from 80 kilometres an hour to 60 around the country, to try to address rising road-deaths.

GoSafe checked the speeds of almost 40-thousand vehicles and detected almost 70 travelling in excess of speed limits.

The council proposes to implement this change from November, unless the Department of Transport advises differently.

The highest day and night readings were recorded at Cloghanboy close, at 75 decibels and 65 decibels respectively.

Locals are expressing concern over the proposed change.
