Gelli Onn on the A484 is one of the town’s main road systems, and the surface is now due for repair.

To keep disruption to a minimum, work will take place during evenings and overnight (7pm-4am).

It will take place in phases over approximately four weeks, starting October 1.

Traffic will be asked to follow diversions, but alternative access arrangements are being put in place for taxis and emergency services.

Letters have also been sent to residents in the vicinity of the works. Most businesses should be unaffected due to the hours of work.

Cllr Hazel Evans, Executive Board Member for Environment, said: “We are investing significantly in sustaining our highway network, with £4million of improvements underway across the county, and the resurfacing of Gelli Onn is part of this programme.

“Gelli Onn is a major part of the road network around Llanelli town centre, so we are mindful that this may cause some traffic disruption. This is why we have planned to undertake the work in phases and outside peak traffic hours to keep disruption. We’d like to thank everyone in advance for their patience and cooperation whilst these essential works are underway.”
