|Route outline (key)|
The B3051 is a rural B-road, mostly in north Hampshire.
It starts in the narrow streets of Overton at traffic lights with the B3400 and heads in a northerly direction, crossing the main West of England Main Line near Overton Station. It continues along a hilly road, including a summit at White Hill, with no more villages until Kingsclere is reached.
The B3051 passes through the village of Kingsclere and crosses the A339 bypass by a staggered crossroads. It then climbs Little Knowl Hill to the village of Ashford Hill, where it descends and turns easterly to Brimpton Common, entering Berkshire en route.
A straight road follows until the B3051 terminates at Heath End at a roundabout on the A340. Originally it continued north most of the way to Aldermaston to end on the original line of the A340. However, that route of the A340 was severed by RAF Aldermaston (now the Atomic Weapons Establishment) leading to the shortening of the B3051.
