The B4240 is a short link road in the Stow Park area of Newport.
Originally the road ended at the far end of Stow Park Avenue at a T-junction meeting with the then A467, Stow Hill. The A467 having been moved to a new alignment, however, the B4240 now turns left and continues for a further 200 metres or so along Stow Hill to end at the point where it meets Caerau Crescent (a branch of the B4591).
