The M25 or London Orbital Motorway is a major road encircling most of Greater London. The 117-mile (188-kilometre) motorway is one of the most important roads in the UK and one of the busiest. Margaret Thatcher opened the final section in 1986, making the M25 the longest ring road in Europe upon opening. The Dartford Crossing completes the orbital route but is not classed as motorway; it is classed as a trunk road and designated as the A282. In some cases, including notable legal contexts such as the Communications Act 2003, the M25 is used as a de facto alternative boundary for Greater London.
The M11 is a 55 miles (89 km) motorway that runs north from the North Circular Road (A406) in South Woodford to the A14, northwest of Cambridge, England. Originally proposed as early as 1915, various plans were considered throughout the 1960s, with final construction being undertaken between 1975 and 1980. The motorway was opened in stages, with the first stage between junctions 7 and 8 opening in June 1975, and the completed motorway becoming fully operational in February 1980. Running from Woodford to Girton, the motorway provides direct access to Harlow, Cambridge and since 2002, greatly improved access to London Stansted Airport.
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 By-pass, which later became part of the M6.
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 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 Westway is a 2.5-mile (4 km) elevated dual carriageway section of the A40 trunk road in West London running from Paddington in the east to North Kensington in the west. It connects the London Inner Ring Road to the West London suburbs.
The M5 is a motorway in England linking the Midlands with the South West. It runs from junction 8 of the M6 at West Bromwich near Birmingham to Exeter in Devon. Heading south-west, the M5 runs east of West Bromwich and west of Birmingham through Sandwell Valley. It continues past Bromsgrove, Droitwich Spa, Worcester, Tewkesbury, Cheltenham, Gloucester, Bristol, Clevedon, Weston-super-Mare, Bridgwater, Taunton, terminating at junction 31 for Exeter. Congestion on the section south of the M4 is common during the summer holidays, on Friday afternoons and bank holidays.
The M23 is a motorway in the United Kingdom, running from the south of Hooley in Surrey, where it splits from the A23, to Pease Pottage, south of Crawley in West Sussex where it rejoins the A23. The northern end of the motorway starts on what is effectively a 2-mile (3.2 km) spur north of junction 7 of the M25 motorway. From Hooley it runs for 17 miles (27 km) past Redhill, Gatwick Airport and Crawley. A spur runs from junction 9 to Gatwick Airport.
The North Circular Road is a 25.7-mile-long (41.4 km) ring road around Central London in England. It runs from Chiswick in the west to Woolwich in the east via suburban North London, connecting various suburbs and other trunk roads in the region. Together with its counterpart, the A205 South Circular Road, it forms a ring road around central London. This ring road does not make a complete circuit of the city, being C-shaped rather than a complete loop as the crossing of the River Thames in the east is made on the Woolwich Ferry.
The South Circular Road in south London, England, is a major road that runs from the Woolwich Ferry in the east to the Chiswick Flyover in the west via Eltham, Lee Green, Catford, Forest Hill, Dulwich, Tulse Hill, Clapham Common, Clapham Junction, Wandsworth, Putney, Barnes, Mortlake and Kew Bridge. Together with the North Circular Road and Woolwich Ferry, it makes a complete ring-road around Central London. The South Circular is largely a sequence of urban streets joined together, requiring several at-grade turns, unlike the mostly purpose-made carriageways of the North Circular. As a result, it is frequently congested.
The M32 is a motorway in South Gloucestershire and Bristol, England, which at roughly 4.4 miles (7.1 km) is one of Britain's shortest. It provides a link from the M4, a major motorway linking London and South Wales, to Bristol city centre and is maintained by National Highways, the national roads body.
Staples Corner is a major road junction in London, United Kingdom. It is about 6.3 miles (10.1 km) north-west from Charing Cross and directly to the west of the Brent Cross crossover.
The Mancunian Way is a two mile long grade separated elevated motorway in Manchester, England. It is officially made up of the A57(M) and A635(M) motorways, although the latter does not appear on road signs for practical reasons. It is also part of two other roads: the A57 to the west, which runs east–west through Greater Manchester linking the M602 and M67 motorways, and a short section of non-motorway A635 to the east. Part of this non-motorway section collapsed on 14 August 2015 due to a sinkhole.
The A419 road is a primary route between Chiseldon near Swindon at junction 15 of the M4 with the A346 road, and Whitminster in Gloucestershire, England near the M5 motorway. The A419 is managed and maintained by a private company, Road Management Group, on behalf of the UK Department for Transport.
The A127, also known as the Southend Arterial Road, is a major road in Essex, England. It was constructed as a new arterial road project in the 1920s, linking Romford with Southend-on-Sea, replacing the older A13. Formerly classified as a trunk road, it was "de-trunked" in 1997. It is known as the Southend Arterial Road except for part of its length in Southend-on-Sea. It is also streetlit for its whole length despite its majority coverage through rural land.
The A316, known in parts as the Great Chertsey Road, is a major road in England, which runs from the A315 Chiswick High Road, Turnham Green, Chiswick to join head-on the M3 motorway at Sunbury-on-Thames. Its initial London section Chiswick Lane heads south – following this it is a mostly straight dual carriageway aligned WSW.
The London Ringways were a series of four ring roads planned in the 1960s to circle London at various distances from the city centre. They were part of a comprehensive scheme developed by the Greater London Council (GLC) to alleviate traffic congestion on the city's road system by providing high speed motorway-standard roads within the capital, linking a series of radial roads taking traffic into and out of the city.
The Hogarth Roundabout sees the merger of two of the nine direct feeders to the main radial roads to or from London. Namely the A316 Great Chertsey Road and the A4 Great West Road in Chiswick. In addition Dorchester Grove, becoming Chiswick Lane, branches off to the north and Church Lane to the conserved, affluent, Old Chiswick nucleus to the south. It contains trees and is much-lined with greenery yet is at surface level, save for a one-way flyover for much of the lighter eastbound traffic.
The A40 is a major trunk road connecting London to Fishguard, Wales. The A40 in London passes through seven London Boroughs: the City of London, Camden, Westminster, Kensington & Chelsea, Hammersmith & Fulham, Ealing and Hillingdon, to meet the M40 motorway junction 1 at Denham, Buckinghamshire.
Chiswick Roundabout is a major roundabout, with flyover, in Chiswick, West London. It was opened in 1959, and is the meeting point of three roads which terminate here, the A205 South Circular, A315 Chiswick High Road, A406 North Circular; and one road which carries on through, and interfaces with the M4 – the A4 Great West Road – therefore it is extremely busy in daytime.
