Draft:A331 Road

The A331 is a primary 'A' road that runs for approximately 13 kilometres (8 mi) through the counties of Hampshire and Surrey in southeast England. It provides a connection between the M3 motorway near Farnborough and the A31 road near Farnham, serving several towns and villages along the way.

Route
The A331 begins at junction 4 of the M3 motorway near the town of Frimley in Surrey. Heading northwards, it passes through Frimley and enters the Hampshire town of Farnborough, intersecting the A325 road. Continuing into Surrey, it runs through the village of Ash Vale where it meets the A323 road which links to the large town of Guildford.

In the village of Tongham, the A331 crosses over the A31 Hog's Back road via the Tongham bypass. The route then terminates shortly after at a roundabout junction with the A31, lying northwest of Tongham and near the town of Farnham.

History
Originally, the A331 formed part of the A31 trunk road between London and Bere Regis in Dorset. The Tongham bypass section was constructed in the late 1960s/early 1970s and redesignated as the A331, separating it from the original A31 route over the Hog's Back ridge.

The southern terminus at Frimley was established in the 1970s when the M3 motorway was extended to that point.
