The B8047 is a link road in West Lothian between the B8028 at Westfield and the B792 at Torphichen, crossing the A801 at a roundabout junction along the way. The road was unclassified in 1922 but had gained its number by 1932; the only change since then is a realignment to join the later A801 roundabout.
The road starts at a TOTSO junction on the B8028 at the western end of Westfield and heads east through the village before swinging south. The land to the right was once a large mill site, but has now been cleared, Climbing a little, the road swings eastwards once more, running nearly straight to the roundabout with the A801. This junction used to be a crossroads, set a little to the north east of the current roundabout, and the old line of the B8047 is still open as property access. However, whilst the new roundabout was designed to suit the plans of the time, as is explained in more detail on that road's page, the next section of the A801 to the north was never built, meaning that whilst the eastern arm of the roundabout was intended to just carry the B8047 traffic, it is still the A801, forcing the B8047 into a T junction from the busy main road.
The next section of the B8047 continues eastwards at first, before turning sharp right to head almost due south, after which there's another sharp bend to the east once more. The road still feels rural at first, but the first houses of Torphichen are hidden in the trees to the right, and then a 40 limit is reached, with the road narrowing shortly afterwards. The road climbs a little over a slight hill and then winds between stone walls into the village proper. The village centre lies to the north on the B792, which turns to run parallel to the B8047 for a while, before turning again and meeting our road at a staggered crossroads, marking the end of the B8047.
