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 a trunk road 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.
Ermine Street is a major Roman road in England that ran from London (Londinium) to Lincoln and York (Eboracum). The Old English name was Earninga Strǣt (1012), named after a tribe called the Earningas, who inhabited a district later known as Armingford Hundred, around Arrington, Cambridgeshire, and Royston, Hertfordshire. "Armingford", and "Arrington" share the same Old English origin. The original Celtic and Roman names for the route remain unknown. It is also known as the Old North Road from London to where it joins the A1 Great North Road near Godmanchester.
The A1, also known as the Great North Road, is the longest numbered road in the United Kingdom, at 410 miles (660 km). It connects London, the capital of England, with Edinburgh, the capital of Scotland. The numbering system for A-roads, devised in the early 1920s, was based around patterns of roads radiating from two hubs at London and Edinburgh. The first number in the system, A1, was given to the most important part of that system: the road from London to Edinburgh, joining the two central points of the system and linking the UK's (then) two mainland capital cities. It passes through or near north London, Hatfield, Welwyn Garden City, Stevenage, Baldock, Letchworth Garden City, Biggleswade, Eaton Socon, Buckden, Peterborough, Stamford, Grantham, Newark-on-Trent, Retford, Doncaster, Pontefract, York, Wetherby, Ripon, Darlington, Durham, Gateshead, Newcastle upon Tyne, Morpeth, Alnwick and Berwick-upon-Tweed.
Royston is a town and civil parish in the District of North Hertfordshire and county of Hertfordshire in England.
The A14 is a major trunk road in England, running 127 miles (204 km) from Catthorpe Interchange, a major intersection at the southern end of the M6 and junction 19 of the M1 in Leicestershire to the Port of Felixstowe, Suffolk. The road forms part of the unsigned Euroroutes E24 and E30. It is the busiest shipping lane in East Anglia carrying anything from cars to large amounts of cargo between the UK and Mainland Europe.
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 N11 road is a national primary road in Ireland, running for 129 km (80 mi) along the east side of Ireland from Dublin to Wexford. It passes close to Bray, Greystones, Wicklow, Arklow, Gorey, and Enniscorthy. Beyond Wexford, the route continues to Rosslare as the N25. The road forms part of European route E01. As of July 2019 the N11/M11 is of dual carriageway or motorway standard from Dublin as far as Oilgate in County Wexford.
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 South Circular Road, it mostly forms a ring road around central London, except for crossing of the River Thames, which is done by the Woolwich Ferry.
East Hertfordshire is one of ten local government districts in Hertfordshire, England. Its council is based in Hertford, the county town of Hertfordshire. The largest town in the district is Bishop's Stortford, and the other main towns are Ware, Buntingford and Sawbridgeworth. At the 2011 Census, the population of the district was 137,687. By area it is the largest of the ten local government districts in Hertfordshire. The district borders North Hertfordshire, Stevenage, Welwyn Hatfield and Broxbourne in Hertfordshire, and Epping Forest, Harlow and Uttlesford in Essex.
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 A414 is a major road in England, which connects the towns of Hemel Hempstead in Hertfordshire and Maldon in Essex. The road commences at the A41, at a junction west of Hemel, and travels through the town to junction 8 of the M1 motorway at Buncefield. From there, it runs parallel to the M1 until junction 7, heading south of St Albans and east through Hatfield and Hertford. The road then crosses the A10 and into Essex; it travels through Harlow, Chipping Ongar and Chelmsford, before terminating at Maldon.
The A1309 is a short road which links the two ends of the A10 to north and south of Cambridge city centre in Cambridgeshire, England. It was numbered as part of the A10 prior to the construction of the Cambridge Western Bypass and the Northern Bypass.
The A249 is a road in Kent, England, running from Maidstone to Sheerness on the Isle of Sheppey. It mainly functions as a link between the M2 and M20 motorways, and for goods vehicle traffic to the port at Sheerness.
The A120 is an A-road in England, which runs between Puckeridge in Hertfordshire and Harwich in Essex.
The A505 is a road in the East of England. It follows part of the route of the Icknield Way and the corresponding Icknield Way Path and runs from Leighton Buzzard in Bedfordshire to the A11 Abington Interchange North in Cambridgeshire.
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 M12 motorway was a planned motorway starting in north-east London and joining the A12 road in Essex. The 1960s scheme would have started at a junction with the M11 motorway and North Circular and ended near Brentwood, Chelmsford, or at the proposed new Maplin Sands airport; the motorway was part of the ambitious London Ringways plan to build motorways throughout London. Although most of the Ringways plan was cancelled in 1969 the M12 motorway project was still included in the Roads for Prosperity white paper published in 1989 along with major proposed developments to the A12 road. It was not formally cancelled until 30 March 1994 by the Secretary of State for Transport, John MacGregor.
The A130 is a major road in England linking Howe Green, near Chelmsford, the county town of Essex, with Canvey Island in the south of that county. It is a primary route for some of its length, only losing that status south of the A13 junction at Sadlers Farm roundabout as it nears its terminus on Canvey Island. It was originally a much longer cross-country route.
The A1 in London is the southern part of the A1 road. It starts at Aldersgate in the City of London, passing through the capital to Borehamwood on the northern fringe of Greater London, before continuing to Edinburgh. The road travels through the City and three London boroughs: Islington, Haringey and Barnet, which include the districts of Islington, Holloway, Highgate, Hendon and Mill Hill, and travels along Upper Street and Holloway Road, crossing the North Circular Road in Hendon, a district in the London Borough of Barnet.
