A SERIES of traffic incidents had closed the A40 in both directions this morning between Haverfordwest and Canaston Bridge roundabout.
A council worker told a Herald reporter that a broken down lorry and an accident involving a car was causing the delay.
It is not clear if the two incidents are related.
Dyfed-Powys Police said on Twitter: “A40 Arnolds Hill currently blocked both directions due to a stranded lorry. Please avoid the area.”
The road has been closed since around 6:45am and there are long traffic tailbacks as morning commuters are diverted around the road. It has since been re-opened.
