International E-road network in the context of "A14 road (England)"

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 two of the UK's mainland capital cities. It passes through or near north London, Hatfield, Stevenage, Baldock, Biggleswade, Peterborough, Stamford, Grantham, Newark-on-Trent, Retford, Doncaster, Pontefract, York, Wetherby, Ripon, Darlington, Durham, Gateshead, Newcastle upon Tyne, Morpeth, Alnwick, Berwick-upon-Tweed, Dunbar, Haddington, Musselburgh, and east Edinburgh.

It was designated by the Ministry of Transport in 1921, and for much of its route it followed various branches of the historic Great North Road, the main deviation being between Boroughbridge and Darlington. The course of the A1 has changed where towns or villages have been bypassed, and where new alignments have taken a slightly different route. Between the North Circular Road in London and Morpeth in Northumberland, the road is a dual carriageway, several sections of which have been upgraded to motorway standard and designated A1(M). Between the M25 (near London) and the A720 (near Edinburgh) the road is part of the unsigned Euroroute E15 from Inverness to Algeciras.

The M6 motorway is the longest motorway in the United Kingdom. It is located entirely within England, running for just over 230 miles (370 km) from the Midlands to the border with Scotland. It begins at Junction 19 of the M1 and the western end of the A14 at the Catthorpe Interchange, near Rugby before heading north-west. It passes Coventry, Birmingham, Wolverhampton, Stoke-on-Trent, Preston, Lancaster and Carlisle and runs between Manchester and Liverpool before terminating at Junction 45 near Gretna. Here, just short of the Scottish border it becomes the A74(M) which continues to Glasgow as the M74. Its busiest sections are between junctions 4 and 10a in the West Midlands, and junctions 16 to 19 in Cheshire; these sections have now been converted to smart motorways.

It incorporated the Preston By-pass, the first length of motorway opened in the UK and forms part of a motorway "Backbone of Britain", running north–south between London and Glasgow via the industrial North of England. It is also part of the east–west route between the Midlands and the east-coast ports. The section from the M1 to the M6 Toll split near Birmingham forms part of the unsigned E-road E 24 and the section from the M6 Toll and the M42 forms part of E 05.

European route E 75 is part of the International E-road network, which is a series of main roads in Europe.

The E 75 starts at the town of Vardø in Norway by the Barents Sea, and it runs south through Finland, Poland, Czech Republic, Slovakia, Hungary, Serbia, North Macedonia, and Greece. The road ends after about 4,380 kilometres (2,720 mi) (not counting ferries) at the town of Sitia on the eastern end of the island of Crete in the Mediterranean Sea, it being the most southerly point reached by an E-road. (The northernmost one is the E69.)

The European route E15 is part of the United Nations international E-road network. It is a north–south "reference road", running from Inverness, Scotland south through England and France to Algeciras, Spain. Along most of its route between Paris and London, the road parallels the LGV Nord (as the French A1 autoroute) and High Speed 1 (as the English M20 motorway). Its length is 2,300 miles (3,700 km).

European route E12 is a road that is part of the International E-road network. It begins in Mo i Rana, Norway, transverses Sweden and ends in Helsinki, Finland, with a ferry line between Sweden and Finland. The part within Finland is Finnish national highway 3. The road is about 910 kilometres (570 miles) in length.

The ferry service between Holmsund and Vaasa is operated by Wasa Line using the M/S Aurora Botnia, with up to two daily departures in each direction taking about three and a half hours.

The European route E 63 is a European route that goes from Sodankylä, Finland to Turku, Finland. The length of the route is 1,126 kilometres (700 mi).

• E 63: Sodankylä – Pelkosenniemi – Kemijärvi – Isokylä – Kuusamo – Suomussalmi – Kajaani – Iisalmi – Kuopio – Vehmasmäki – Suonenjoki – Laukaa – Jyväskylä – Jämsä – Orivesi – Tampere – Akaa – Loimaa – Turku

The E63 is the only European route that runs entirely in Finland. It follows Finnish national highway 5 between Sodankylä and Kuopio and highway 9 between Kuopio and Turku.

European route E853, formerly the E851 from 1983 to 1986, is a Class B European route in the Greek region of Epirus, running from the regional capital of Ioannina to the Kakavia border crossing with Albania. Introduced in 1983, it is part of the International E-road network, a network of main roads in Europe.

European route E 84 is a road part of the International E-road network. It begins in İpsala border gate (to/from Greece) in Turkey and run through Keşan, Malkara, Tekirdağ and Marmaraereğlisi and ends in Silivri, Turkey.

The road follows: Keşan - Tekirdağ - Silivri. It is a part of the D-110.

European route E80, also known as the Trans-European Motorway or TEM, is an A-Class West-East European route, extending from Lisbon, Portugal to Gürbulak, Turkey, on the border with Iran. The road connects 10 countries and has a length of approximately 6,102 kilometres (3,792 mi). At its eastern end it joins end-on with Asian Highway AH1 which continues all the way to Tokyo, Japan.

Otoyol 4 (English: Motorway 4), named Anatolian Motorway (Turkish: Anadolu Otoyolu) and abbreviated as O-4, is a toll motorway connecting the northwestern Marmara region to the Central Anatolia Region in Turkey. It runs parallel to the D.100 for more than half of its length and then parallels the D750 for most of the eastern half. The O-4 is a major expressway in Turkey as it connects eastern Istanbul and the heavily urbanized northeastern shore of the Sea of Marmara to the nation's capital, Ankara. The O-4 also makes up part of the International E-road network E80 and E89 as well as the AH-1 of the Asian Highway Network.

The O-4 is the longest completed motorway in Turkey spanning 379 km (235 mi), just 14 km (8.7 mi) longer than the O-52. The partially-opened O-5 is expected to surpass the length of the O-4, when it is completed in 2019, with a total length of 407 km (253 mi). but nowadays the longest motorway in Turkey is Otoyol 21 with the opening Ankara-Niğde section. Construction of the O-4 began in 1984 and was widely completed in 1992 except for a short gap through the mountains west of Bolu. This gap was connected in 2006, with the opening of the Mount Bolu Tunnel.

The A74(M) and M74 form a major motorway in Scotland, connecting it to England. The routes connect the M8 motorway in central Glasgow to the Scottish-English border at Gretna. They are part of the unsigned international E-road network E05. Although the entire route is colloquially referred to as the M74, for more than half its length, south of Abington, the road is officially the A74(M); see naming confusion below.

The European route E24 is part of the United Nations international E-road network. It runs for 254 km (158 mi) from Birmingham to Ipswich.

The M42 motorway runs north east from Bromsgrove in Worcestershire to just south-west of Ashby-de-la-Zouch in Leicestershire, passing Redditch, Solihull, the National Exhibition Centre (NEC) and Tamworth on the way, serving the east of the Birmingham metropolitan area. The section between the M40 and junction 4 of the M6 forms – though unsigned as such – a part of Euroroute E05. Northwards beyond junction 11, the route is continued as the A42; the junctions on this section, 12–14, are numbered like a continuation of the motorway, but the road has non-motorway status from here.

The European route E5 is part of the United Nations international E-road network. It is the westernmost north–south "reference road", running from Greenock in Scotland, south through Great Britain and France to Algeciras, Spain. The route is 1,900 miles (3,100 km) long.

European route E20 is a part of the United Nations International E-road network. It runs roughly west–east from Shannon Airport, Ireland to Saint Petersburg, Russia.

Its length is 1,880 km (1,170 mi) but it is not continuous; at three points, a sea crossing is required. Roll-on/roll-off ferries make the crossings between Dublin and Liverpool as well as between Stockholm and Tallinn. No publicly accessible ferries traverse the North Sea from Kingston-upon-Hull to Esbjerg (as of 2019), but a ferry for commercial drivers runs between Immingham and Esbjerg on most days.

European route E952, formerly the E951 from 1983 to 1986, is a Class B European route that runs through Western and Central Greece, from Aktio (el) (near Preveza) through Agrinio to Lamia. Introduced in 1983, it is part of the International E-road network, a network of main roads in Europe.

In Great Britain, there is a numbering scheme used to classify and identify all roads. Each road is given a single letter (representing a category) and a subsequent number (between one and four digits). Though this scheme was introduced merely to simplify funding allocations, it soon became used on maps and as a method of navigation. There are two sub-schemes in use: one for motorways, and another for non-motorway roads.

While some of Great Britain's major roads form part of the international E-road network, no E-routes are signposted in the United Kingdom. Due to changes in local road designation, in some cases roads are numbered out of zone. There are also instances where two unrelated roads have been given exactly the same number; for example, the Leicester Ring Road and a road in Cumbria are both designated A594.

European route E961 is a Class B European route in the Greek regional units of Arcadia and Laconia, running from Tripoli to Gytheio. Introduced as part of the original alignment of the E65 in 1983, it is part of the International E-road network, a network of main roads in Europe.
