The road continues as a minor route between Winchester and the New Forest.
The M27 motorway flows into the road near Lyndhurst, from where it continues as a trunk road through the New Forest and past Ringwood, Ferndown and Wimborne Minster before terminating at its junction with the A35road at Bere Regis.
The A35 is not a trunk road east of Bere Regis, but is a continuation of the A31 trunk road to the west.
