|Route outline (key)|
The B4347 is a long rural B-road on the border between England and Wales.
It starts near Vowchurch in Herefordshire's Golden Valley and follows the edge of the valley of the River Dore downstream, eventually crossing the river to run along the other edge. The road goes through Abbey Dore and Ewyas Harold before getting to Pontrilas, where it meets the A465. This is the original 1922 end of the road but it was extended further in 1935 (in fact the 1932 Ten-Mile Map does not show the road at all but this is presumably an oversight). Our road therefore crosses the A465 at a staggered crossroads. Immediately afterwards it crosses the River Dore again and then TOTSOs right. This section of road is the original line of the A465 which has now been diverted onto the bypass.
The B4347 crosses the Welsh Marches Line and continues along the valley. Just south of Pontrilas the Dore flows into the Monnow and so it is the Monnow that is crossed a mile later at Kentchurch at a narrow bridge, taking the road into Monmouthshire. The road now climbs out of the valley to Grosmont before contouring southeast to Norton, where the B4521 is crossed at a long staggered crossroads.
The road continues vaguely southwards, with two sharp bends near Crossway, before going through Newcastle and descending into the Monnow valley again at Rockfield. The road ends here on the B4233 on the village green.
