Route outline (key)
A475 Newcastle Emlyn – Lampeter
This article is about the present route of A475 through Carmarthenshire.
For the original route between Carmarthen and Swansea, see A475 (Swansea - Carmarthen)


The A475 begins on the A484 in Newcastle Emlyn - a small market town in Carmarthenshire on the picturesque River Teifi.

Newcastle Emlyn – Lampeter

Adpar and the county boundary

The A484 manages to bypass most of Newcastle Emlyn, but the A475 runs through the heart of the town. The actual start point depends on whether you approach from the east or the west, but both legs meet after a few hundred yards in the middle of town. We cross the River Teifi, into Cardiganshire, then turn right to follow the north bank of the Teifi to the east. The A484 mirrors our route, but on the south bank.

At Berthyfedwen we reach the west end of the Teifi Valley railway. There's a left and a right turn, then we climb, steeply at first, away from the Teifi. We pass a right turn onto a road which can best be described as a spur of the B4334 then, after a sharp bend in Aber-banc, we cross the main line of the B4334, which leads south to Henllan on the A484, and north towards the A487.

The A475 west of Llanwnnen

Our hilly single-carriageway road takes us past Penrhiw-llan then on to a junction with the A486 at Horeb. More undulating road follows - we pass through Pren-gwyn (where we meet the B4476), then down into the Clettwr valley and a junction with the B4459 at Rhydowen. We pass more hamlets, crossing the B4338 at Dre-fach (small town!). At Llanwnnen we cross the B4337, before passing through Pentre-bach. The OS Landranger map suggests that we next pass a Leisure Centre on the right, a sign that we are actually arriving at a place that can justifiably call itself a town - Lampeter - where we meet a multiplex of the A482 and A485; the lower number is dominant.


Before 1935 this route (Newcastle Emlyn to Lampeter) was the western end of the A482, which today starts at Aberaeron rather than Newcastle. At that time A475 was the number used for the main road from Carmarthen to Swansea via Pontarddulais – that is to say, the route corresponding to the western end of today's A48.
