The M1 motorway connects London to Leeds, where it joins the A1(M) near Aberford, to connect to Newcastle. It was the first inter-urban motorway to be completed in the UK; the first motorway in the country was the Preston Bypass, which later became part of the M6.
The M40 motorway links London, Oxford, and Birmingham in England, a distance of approximately 89 miles (143 km).
The A5, the London-Holyhead trunk road, is a major road in England and Wales. It runs for about 243 miles (391 km) from London to the Irish Sea at the ferry port of Holyhead. In many parts the route follows that of the Roman Iter II route which later took the Anglo-Saxon name Watling Street.
The A6 is one of the main north–south roads in England. It runs from Luton in Bedfordshire to Carlisle in Cumbria, although it formerly started at a junction with the A1 at Barnet in north London, and is described as running from London to Carlisle. It is the fourth longest numbered road in Britain; only the A1, A38 and A30 are longer.
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 A57 is a major road in England. It runs east from Liverpool to Lincoln via Warrington, Salford and Manchester, and then through the Pennines over the Snake Pass (between the high moorlands of Bleaklow and Kinder Scout), around the Ladybower Reservoir, through Sheffield and past Worksop. Between Liverpool and Glossop, the road has largely been superseded by the M62, M602 and M67 motorways. Within Manchester a short stretch becomes the Mancunian Way, designated A57(M).
The A20 is a major road in south-east England, carrying traffic from London to Dover in Kent. Parts of the route date back to turnpikes established in the early part of the 18th century. The line of the road throughout Kent runs closely in parallel with the M20 motorway.
The A47 is a major trunk road in England linking Birmingham to Lowestoft, Suffolk, maintained and operated by National Highways. Most of the section between Birmingham and Nuneaton is now classified as the B4114. From Peterborough eastwards, it is a trunk road.
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 A49 is an A road in western England, which traverses the Welsh Marches region. It runs north from Ross-on-Wye in Herefordshire via Hereford, Leominster, Ludlow, Shrewsbury and Whitchurch, then continues through central Cheshire to Warrington and Wigan before terminating at its junction with the A6 road just south of Bamber Bridge, near the junction of the M6, M65 and M61 motorways.
The A45 is a major road in England. It runs east from Birmingham past the National Exhibition Centre and the M42, then bypasses Coventry and Rugby, where it briefly merges with the M45 until it continues to Daventry. It then heads to Northampton and Wellingborough before running north of Rushden and Higham Ferrers and terminating at its junction with the A14 in Thrapston.
The A52 is a major road in the East Midlands, England. It runs east from a junction with the A53 at Newcastle-under-Lyme near Stoke-on-Trent via Ashbourne, Derby, Stapleford, Nottingham, West Bridgford, Bingham, Grantham, Boston and Skegness to the east Lincolnshire coast at Mablethorpe. It is approximately 147 miles (237 km) long.
The A64 is a major road in North and West Yorkshire, England, which links Leeds, York and Scarborough. The A64 starts as the A64(M) ring road motorway in Leeds, then towards York it becomes a high-quality dual carriageway until it is east of the city, where it becomes a single carriageway for most of its route to Scarborough.
The A4540 is a ring road in Birmingham, England, also known as the Middle Ring Road, or the Middleway. It runs around the centre of the city at a distance of approximately 1 mile (1.6 km). Birmingham City Centre is the area within this ring road. The ring road was planned and designed by Herbert Manzoni. It is now simply known as the Ring Road due to the removal of the old Inner Ring Road.
Known as the Hagley Road in Birmingham, the A456 is a main road in England running between Central Birmingham and Woofferton, Shropshire, south of Ludlow. Some sections of the route, for example Edgbaston near Bearwood, are also the route of the Elan Aqueduct which carries Birmingham's water supply from the Elan Valley.
The A43 is a primary route in the English Midlands and northern South East England, that runs from the M40 motorway near Ardley in Oxfordshire to Stamford in Lincolnshire. Through Northamptonshire it bypasses the towns of Northampton, Kettering and Corby which are the three principal destinations on the A43 route. The A43 also links to the M1 motorway.
The A4150 Wolverhampton Inner Ring Road is a ring road that encircles the city centre of Wolverhampton in the West Midlands, England. The circumference of the road is around 2.1 miles (3.4 km). Technically, the route is listed as an "Inner Ring Road", although only a tiny section of the "Outer Ring Road" was ever constructed with only one of the two designed carriageways built. A second carriageway was built in 2017 along a short stretch between Patshull Avenue and Stafford Road. The section of outer ring road is called Wobaston Road and locally classified by Wolverhampton City Council as U119.
The A405 is a 4.8 miles dual carriageway road in Hertfordshire, England, from the A41 at Leavesden Green, near Watford, to the A414 at Park Street Roundabout near St Albans.
The City of Peterborough in East Anglia has an extensive and well integrated road network, owing partly to its status as a new town. Since the 1960s, the city has seen considerable expansion and its various suburbs are linked by a system of parkways.
Transport in Buckinghamshire has been shaped by its position within the United Kingdom. Most routes between the UK's two largest cities, London and Birmingham, pass through this county. The county's growing industry first brought canals to the area, then railways and then motorways.
