The old route to Winchester's centre then Romsey and the New Forest forms two roads: the B3404 and A3090 roads and is marked for cyclists. The west branch of the M27 motorway - M3 interchange has a flyover junction with the winding westbound A3090 on the western boundary of Cadnam, having passed through the conservation area village centre, from where the resumed A31 continues as a dualled trunk road through the rest of the New Forest, past Ringwood and enters Dorset just before it passes Ferndown where it resumes single carriageway width. It passes Wimborne Minster and by-passes Charborough Park before terminating at a roundabout junction with the A35 road 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, thus the Highways Agency maintain it.
