The A40 between St Clears and Haverfordwest is mainly a single carriageway. Works to make improvements to the existing road between Llanddewi Velfrey and Redstone Cross to improve safety and to incorporate new cycling and walking routes.
For more information about this project, please see Welsh Government link for information on traffic management see details below.
The completion of Penblewin roundabout will take place over six weekend with traffic management. This avoids a full closure of the A40 trunk road. Those traveling in the area should allow extra time for their journey. The Penblewin truck stop will also be closed during these weekend closures.
