A4138 road

The A4138 is a main road in Carmarthenshire, Wales, connecting Pontarddulais with Llanelli. Running in a north-east to south-west direction, the road connects with [[Image:Motorway Left.svg|[ |x22px|link=]] M4 Junction 48.

North-east of the motorway, the road is classified as a non primary route, while south-west of the motorway, the road is classified as a primary route. In both instances, the road is operated by Carmarthenshire County Council.

Proposals

There have been proposals to make the southwestern section from the M4 to Llanelli a trunk road, which would be operated by the Welsh Assembly Government, but these have been rejected.

The local council has a policy to reject any planning application that would prevent or adversely affect the implementation of a dual carriageway between the M4 and Trostre.
