The A31 is a major trunk road in southern England that runs from Guildford in Surrey to Bere Regis in Dorset.

[edit] Route of road
The road begins in the centre of Guildford, meeting the A3 road before running south west along the Hog's Back. It continues past Farnham, Alton and New Alresford before joining the route of the M3 motorway at its junction just east of Winchester. The original route from Alresford to Winchester is now the B3404 and from Winchester is now a minor A-road A3090 road through Romsey and on to the New Forest. The M27 motorway flows seamlessly 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 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.
The A31 is part of the ancient route from London to Winchester.
The A31 between Wimborne Minster and Bere Regis is primarily a single-carriageway road, used by heavy goods vehicles and as such is particularly slow, especially during busy times of the day.
[edit] A31 New Forest Dual Carriageway
Many sections of the A31 were upgraded to dual carriageway in the 1960s, except for the section of road running through the New Forest.[1]
The upgrade of the A31 through the New Forest started in the early 1960s, following two decades of debate. The Government's intention was to create at least one high-speed route to the south coast, while the guardians of the forest, the Verderers, resisted any further development.[2][3]
The first section of the A31 to be dualled was the section that the M27 feeds into at Jct1; the westbound carriageway is the original two-way A-road while the eastbound side was laid down nearby. Further developments occurred from Ringwood to Picket Post near the turn-off for Burley. From 1966-1972, the remaining sections were completed rapidly due to the construction of the M27 motorway up to Jct 1.[4]
The Highways Agency declares the New Forest A31 section as being 'an abnormal and heavy load route'.[5] The westbound route, particularly, suffers from poor horizontal and vertical alignment due to its original function as an old single carriageway. The Highways Agency's route management strategy (RMS) for the A31 has identified that the westbound carriageway needs realigning at Cadnam where it undulates rapidly before negotiating a sharp right turn and passes an at-grade U-turn box, though there is no timetable for this at present. There is also a pinch point at Ringwood where the A31 interplexes with the A338; the section of road was widened to four lanes each way for the duration of the A338 interplex (following the upgrade of the Ashley Heath Junction to Bournemouth in the early 1990s) but a short section where westbound A338 traffic joins westbound A31 was left with 2 lanes, and the lack of capacity at this section causes safety problems and queues at peak times. Dorset County Council cites relieving this junction as a high priority in the Bournemouth LTP 2006-2011.[6]
[edit] A31 Between Bere Regis and Wimborne
This section of road is single carriageway for its entire length, a long section around Winterborne Zelston has a 40 mph speed limit, and occasionally has mobile speed cameras in place.
There are no good overtaking places on this stretch of road due to its narrow, twisty nature. There are three long straight sections of road along Charborough Park, at the end of each straight there is blind bend. Due to the lack of alternative overtaking places traffic use this stretch of road to overtake, but due to the blind bends this sometimes results on head on collisions between vehicles. The 6 ft wall that runs alongside the road has many holes, and repaired sections which have been hit by cars over the years.
The A31 crosses the A350 at a large roundabout. Due to the volume of traffic crossing this roundabout on both the A350 and A31, clear lane markings have been added to ease congestion.
A few sections along the A31 have been widened or straightened over the years, and a few junctions have been enhanced.
This is the primary route into Dorset, and as such contains a high number of HGVs.

A section of the A31 between Winchester and Ower in Hampshire is now known as the A3090.
Prior to completion of the M3 past Winchester in the 1995, the A3090 ran south west from the A33 at Kings Worthy (where the A33 diverted around the Winchester Bypass) to the centre of Winchester, before continuing along the historic route of the A31 from Winchester to Hursley. Here it ended at a junction with the A31, which at this time, having merged with the by-pass east of Winchester, re-emerged from the A33 at Otterbourne and ran to Hursley and on along the current route of the A3090.[7]
A short dual carriageway section starts from the A36 roundabout near Ower and terminates just before the A27 multiplex south west of Romsey.
