B4329 road

The B4329 is a scenic route and former turnpike linking Eglwyswrw and Haverfordwest, Pembrokeshire, by crossing the Preseli Mountains in an approximately north-south direction. The road is 18.8 miles (30.3 km) long and varies in elevation from 100–404 metres (328–1,325 ft) above sea level. Much of the road is through farmland with scattered settlements, and a section through high moorland grazing with extensive views.

The road has been the main link between Eglwyswrw and Haverfordwest since mediaeval times, and was subsequently turnpiked. In Lewis's 1833 Topographical Dictionary of Wales it is described as the "great road" linking Cardigan with Haverfordwest. While the A487 (Cardigan to Fishguard) and A40 (Fishguard to Haverforwest) sections were later upgraded to trunk routes, the direct route was not, and was designated in the early 20th century road classification scheme as the B4329. Before that, when most journeys were made on foot, horseback or horse-drawn vehicle, travellers were provided for by inns along the route, such as those at Crosswell, Tufton, Greenway and Crundale, most of which no longer trade.

Branching from the A487 half a mile south-west of Eglwyswrw, the road drops down to cross the River Nevern by a single-lane stone bridge just north of the hamlet of Crosswell. The road enters the Pembrokeshire Coast National Park, then climbs steadily through farmland, over a 400-year-old bridge crossing the Afon Brynberian, and past the hamlet of Brynberian with views of the mountains to the south and east.

The gradient increases until the road passes the site of Tafarn-y-Bwlch (approximate English: Tavern at the Pass), an inn which existed at least as early as 1729. The road crosses a cattle grid marking a boundary between enclosed agricultural land and unenclosed moorland and continues to climb to 404 metres (1,325 ft) between Carn Lladron and Mynydd-du Commin.
