The A31 is a major trunk road in southern England that runs from Guildford in Surrey to Bere Regis in Dorset.
The road begins in Guildford at the start of Farnham Road near Guildford Station, coming out of the town and passing over the A3 where shortly after it becomes a dual carriageway running in a westerly direction along the Hog's Back escarpment of the North Downs. At Tongham it leaves the older Hogs Back route to join with the A331 and follow a modern bypass round Farnham, rejoining the older route at the roundabout junction with the A325 where it follows Alton Road toward Alton which it bypasses, rejoining the older route near Jane Austen's house, then continuing to Alresford before joining the route of the M3 motorway at its junction on the eastern boundary of Winchester.
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.
