Traffic restrictions are expected at the Kirwan roundabout on the Headford Road, Bothar na dTreabh, and surrounding areas this month.
Temporary restrictions will be in place at the junction and adjacent sections of public roads in July to allow works removing the roundabout to take place.
Traffic management and advance diversion signage will be in place prior to work commencing.
The first of these will be an overnight closure of the N84 Headford Road at the junction on Monday, July 5.
The section of the road being worked on will be closed from 7pm on Monday evening, until 7am on Tuesday morning.
Flagmen will be present at key diversion points to direct traffic onto the signed diversion routes, and delays are expected.
Local and emergency access will be facilitated at all times.
