|Route outline (key)|
The B4325 is a largely urban B-road in west Pembrokeshire.
It starts to the north of central Milford Haven on the A4076 and heads east out of town before crossing a creek. It then heads east into Waterston, passing its oil refinery and gas terminal and crossing the railway line providing access. Vehicular access is from the centre of Waterston itself.
The road then heads northeast to Scoveston Fort and then southeast into Neyland. It runs along the estuary for a short distance and then doubles back to head north and terminate at a roundabout on the A477.
The reason for the unusual route in Neyland is that the B4325 used to end on the B4324 by the quay, from where a ferry took traffic across to Pembroke Dock. When the main road across the estuary (by then renumbered A477) was rerouted onto the new Cleddau Bridge in the 1970s the B4325 was extended to meet it.
The original route of the B4325, however, contained none of the above. It still linked the A4076 and B4324, albeit further north avoiding Milford Haven and Neyland completely. It was moved onto its current more southerly route later in the 1920s.
