The route continues, crossing the A24 and passing through a number of villages and small towns in West Sussex, such as Billingshurst, Petworth and Midhurst. It then crosses the county boundary into Hampshire and reaches Petersfield, where it crosses the A3 to the west of the town. The final section passes the National Trust property of Hinton Ampner and rises high on to the Hampshire downs, passing Cheesefoot Head, before descending to merge with the A31 at Chilcomb to the east of Winchester.
