The A40 will be closed for the weekend in both directions at Ffynnon Woods, west of Llandewi Velfrey from 8pm tonight.
The closure will start at 8pm on Friday June 16 and finish at 6am on Monday June 19, according to Traffic Wales, the Welsh Government’s traffic information service for motorways and trunk roads in Wales.
The A40 between St Clears and Haverfordwest is mainly a single carriageway. Improvement works are being made to the existing road between Llanddewi Velfrey and Redstone Cross to improve safety and to incorporate new cycling and walking routes.
Abnormal loads that cannot use the A477 Cleddau Bridge will be held at the work site and escorted to the secondary diversion route via Cross Hands.
