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.
The M4, originally the London-South Wales Motorway, is a motorway in the United Kingdom running from west London to southwest Wales. The English section to the Severn Bridge was constructed between 1961 and 1971; the Welsh element was largely complete by 1980, though a non-motorway section around Briton Ferry bridge remained until 1993. On the opening of the Second Severn Crossing in 1996, the M4 was rerouted over it.
The M40 motorway links London, Oxford, and Birmingham in England, a distance of approximately 89 miles (143 km).
The M3 is a motorway in England, from Sunbury-on-Thames, Surrey, to Eastleigh, Hampshire; a distance of approximately 59 miles (95 km). The route includes the Aldershot Urban Area, Basingstoke, Winchester, and Southampton.
The A34 is a major road in England. It runs from the A33 and M3 at Winchester in Hampshire, to the A6 and A6042 in Salford, close to Manchester City Centre. It forms a large part of the major trunk route from Southampton, via Oxford, to Birmingham, The Potteries and Manchester. For most of its length, it forms part of the former Winchester–Preston Trunk Road. Improvements to the section of road forming the Newbury Bypass around Newbury were the scene of significant direct action environmental protests in the 1990s. It is 151 miles (243 km) long.
The M27 is a motorway in Hampshire, England. It is 27.9 miles (44.9 km) long and runs between Cadnam and Portsmouth. It was opened in stages between 1975 and 1983, providing the largest two urban areas in Hampshire with a direct motorway link. An extension into the county of West Sussex was planned but never constructed. A number of smaller motorways were proposed, connecting the city centres of Southampton and Portsmouth to the motorway; of these only the M271 and M275 were built. Three sections of the M27 have since been widened to four lanes each way, the first between junctions 7 and 8, the second between junctions 3 and 4, and the third begins at the slip road where junction 11 joins until mid-way to junction 12.
The A12 is a major road in Eastern England. It runs north-east/south-west between London and the coastal town of Lowestoft in the north-eastern corner of Suffolk, following a similar route to the Great Eastern Main Line until Ipswich. A section of the road between Lowestoft and Great Yarmouth became part of the A47 in 2017. Between the junctions with the M25 and the A14, the A12 forms part of the unsigned Euroroute E30. Unlike most A roads, this section of the A12, together with the A14 and the A55, has junction numbers as if it were a motorway.
The A36 is a trunk road and primary route in southwest England that links the port city of Southampton to the city of Bath. At Bath, the A36 connects with the A4 to Bristol, thus providing a road link between the major ports of Southampton and Bristol. It also provides a link between Bristol and London via the A303.
The A11 is a major trunk road in England. It originally ran roughly north east from London to Norwich, Norfolk. It now consists of a short section in Inner London and a much longer section in Cambridgeshire, Suffolk and Norfolk. The lengthy section between these was renumbered as a result of the opening of the M11 in the 1970s and then the A12 extension in 1999.
The A27 is a major road in England. It runs from its junction with the A36 at Whiteparish in the county of Wiltshire, follows the south coast of Hampshire and West Sussex, and terminates at Pevensey in East Sussex.
The A21 is a trunk road in Southern England, one of several which connect London and various commuter towns to the south coast. It provides a link to Hastings, East Sussex and parts of Kent. Half of the distance covered is over gently undulating terrain, with some hills and bends. Often traffic is slow-moving, particularly on weekdays on the short single carriageway stretches; and in summer with holiday traffic. Because of this, people have described the A21 as "a joke" and businesspeople have been reported to "hate coming down the A21". There have been many proposals to upgrade parts of the A21 in response to this.
The A35 is a major road in southern England, connecting Honiton in Devon and Southampton in Hampshire. It is a trunk road for some of its length. Most of its route passes through Dorset and the New Forest. It originally connected Exeter and Southampton, the original A35 ran along what is now the A3052 joining the present road at Charmouth.
The A33 is a major road in the counties of Berkshire and Hampshire in southern England. The road currently runs in three disjoint sections.
The A350 is a north–south primary route in southern England, that runs from the M4 motorway in Wiltshire to Poole in Dorset.
The A428 road is a major road in central and eastern England. It runs between the cities of Coventry and Cambridge by way of the county towns of Northampton and Bedford. Together with the A421,, the eastern section of the A428 forms the route between Cambridge and Oxford. The A428 was formerly part of the main route from Birmingham to Felixstowe before the A14 was fully opened in 1993.
The A453 road was formerly the main trunk road connecting the English cities of Nottingham and Birmingham. However, the middle section of this mainly single-carriageway road has largely been downgraded to B roads or unclassified roads following the construction of the parallel M42-A42 link around 1990. The M42 was originally meant to pass further north than it does, and to join the M1 at Sandiacre in Derbyshire. The M42/A42 does not enter Derbyshire, but instead joins the M1 closer to the A453 junction at Kegworth. The A42 shadows the former A453 from Appleby Magna to Castle Donington. The road historically connected the East Midlands with the West Midlands.
The South East Dorset conurbation is a multi-centred conurbation on the south coast of Dorset in England.
The A338 is a major primary route in southern England, that runs from the junction with the A35 at Poole in Dorset to the junction with the A420 at Besselsleigh in Oxfordshire, a distance of 84 miles (135 km).
Dorset is a county in South West England. The county is largely rural and therefore does not have a dense transport network, and is one of the few English counties without a motorway. Owing to its position on the English Channel coast, and its natural sheltered harbours, it has a maritime history, though lack of inland transport routes have led to the decline of its ports.
Picket Post is a road junction and service area in the New Forest National Park of Hampshire, England. It lies on the A31 road.
