|Route outline (key)|
The B3255 is described in the 1922 Road Lists as a link at Callington.
The route of the road made it ideal to being upgraded to become the Callington bypass and that is what is now, although the renumbering did not take place until the late 1980s. The former A390 through the centre of town is now unclassified and the ex-B3255 is now the main line of that road.
