|Route outline (key)|
The B3257 is a road of three parts in Cornwall and Devon.
The road heads southeast skirting the moor. It soon crosses the B3254 before going through the small villages of Coad's Green and Bray Shop before reaching the A388 at a T Junction at Taylor Shop. A multiplex of about a mile south along the A388 follows as far as Kelly Bray.
From Kelly Bray the B3257 follows its own course round the northern side of Kit Hill, passing through no villages en route, until it joins the A390 at a T Junction on Hingston Down. Once again it forms a multiplex - nearly five miles this time - east along the A390. It crosses into Devon at Gunnislake before climbing up to a roundabout at Gulworthy.
The third section of the B3257 heads south along the Bere Peninsula. The first place of any size met is Bere Alston, where the road ends at a T Junction on an unclassified road in the centre of the village.
Originally the B3257 was far more orthodox.
The road remained wholly in Cornwall until around 1990. However, it has now been extended to Bere Alston via an unusually long multiplex.
