The A3, known as the Portsmouth Road or London Road in sections, is a major road connecting the City of London and Portsmouth passing close to Kingston upon Thames, Guildford, Haslemere and Petersfield. For much of its 67-mile (108 km) length, it is classified as a trunk road and therefore managed by National Highways. Almost all of the road has been built to dual carriageway standards or wider. Apart from bypass sections in London, the road travels in a southwest direction and, after Liss, south-southwest.

Godalming is a market town and civil parish in southwest Surrey, England, around 30 miles (49 km) southwest of central London. It is in the Borough of Waverley, at the confluence of the Rivers Wey and Ock. The civil parish covers 3.74 sq mi (9.7 km2) and includes the settlements of Farncombe, Binscombe and Aaron's Hill. Much of the area lies on the strata of the Lower Greensand Group and Bargate stone was quarried locally until the Second World War.
