Heading west

The original route of the B4319 headed west along the coast from the Pembrokeshire coastal town of Tenby.

It started on the A478 on the Tenby sea front and headed west through town, passing under the railway viaduct on Greenhill Road. The next village was Penally, after which the road went under the railway line again at a very tight zigzag.

The road continued west via Lydstep, passing to the north of Manorbier, before crossing the railway line again at Lamphey. It then entered Pembroke where there was yet another railway overbridge before the road ended immediately afterwards on the A4075 (former B4320).

In 1935 the road was upgraded to Class I status, becoming the similarly numbered A4139. A few improvements aside, this is its current number.
