|Route outline (key)|
The B4324 was a short link road in western Pembrokeshire.
The road passed through no places of any size en route. It eventually entered Neyland where it went along the High Street and ended on the quay, from where a ferry crossed the River Cleddau to reach the A477 in Pembroke Dock.
In the 1960s the whole of the B4324 was renumbered as an extension of the A477. With the building of the Cleddau Bridge the A477 was rerouted that way and the ferry discontinued; the southernmost section of the ex-B4324 is now an extension of the B4325.
