A trailer overturned on A40 roundabout near Canaston Bridge earlier, spilling seed across the busy carriageway.
Dyfed Powys Police were at the scene directing traffic whilst recovery work was carried out.

The following tweets were sent by the Pembrokeshire Road Policing Unit:

The Western Telegraph traffic update reported: "Delays and partially blocked road due to shed load of seeds and recovery work."

The recovery work has since been completed and tailbacks are easing.
