About A478 Road
The A478 road is a major route in the Welsh counties of Pembrokeshire and Carmarthenshire, connecting Cardigan (junction with the A487 Cardigan bypass) and Tenby. The road crosses the Preseli Hills and for almost all of its route winds through farmland. HistoryThe northern two-thirds of the A478 was for some centuries a drovers' road transporting goods and livestock from north Pembrokeshire and Ireland (Cardigan was then a port) before the coming of the railways in the mid-19th century. The road was turnpiked probably in the 18th century. There have been only minor and local deviations in the route, principally to improve river crossings and eliminate dangerous bends. Short sections of the original road, little more than a country lane, can still be seen, as can some early stone bridges. RouteOne mile south of Cardigan the road bridges the River Piliau and crosses the county boundary into Pembrokeshire at Glanpwllafon. It then runs through Pen-y-bryn village and Bridell hamlet, bridges the River Plysgog and continues to Rhoshill hamlet, after which it is crossed by the B4332 Eglwyswrw-Cenarth road. The road then climbs the northern slopes of the eastern end of the Preseli Hills through Blaenffos village, bridging the River Nevern (near its source) at Riverlea, to Crymych village.
