Document 2: A5 road (Latvia): The A5 is a national road in Latvia which is part beltway around Riga, connecting Salaspils to Babīte. The road is also known as Riga bypass. The road is part of European route E67, European route E77 and Latvian TEN-T road network. The length of A5 is 41 kilometer. Currently A5 has 1x1 lanes until interchange with A9 then it turns to 2x2 all the way until Babīte. Most of the traffic on A5 is made up by trucks. A5 crosses river Daugava on Riga HES, and the A5 part on the HES has been reconstructed in 2010/2011. Another part of A5 between A8 and A9 was reconstructed in 2011. There are plans to build a new bridge over Daugava opposite to the end of A4 (part of Riga bypass on other side of Daugava), in further future. Current speed limit is 90 km/h. The average AADT of A5 in 2016 was 12 482 cars per day.
Document 3: M22 motorway (Northern Ireland): The M22 is a motorway in County Antrim, Northern Ireland. It is 5.6 miles (9 km) long and connects the A6 with the M2. It forms part of the unsigned European route E16.
Document 4: M2 motorway (Northern Ireland): The M2 is a motorway in Belfast and County Antrim in Northern Ireland. It is in two sections, the southern section running from north Belfast to Antrim and the northern section acts as a bypass of Ballymena, with the A26 road linking the two sections. In total it is 22 miles (36.2 kilometres). The M2 has the busiest sections of any road or motorway in Northern Ireland. The M2 is one of Northern Ireland's most important motorways, forming most of the main route from Belfast city to both Belfast International Airport and less than a quarter of the way to Derry. It forms part of the unsigned European route E01, E16 and E18 roads.
Document 5: Hanover: The Schnellweg (en: expressway) system, a number of Bundesstraße roads, forms a structure loosely resembling a large ring road together with A2 and A7. The roads are B 3, B 6 and B 65, called Westschnellweg (B6 on the northern part, B3 on the southern part), Messeschnellweg (B3, becomes A37 near Burgdorf, crosses A2, becomes B3 again, changes to B6 at Seelhorster Kreuz, then passes the Hanover fairground as B6 and becomes A37 again before merging into A7) and Südschnellweg (starts out as B65, becomes B3/B6/B65 upon crossing Westschnellweg, then becomes B65 again at Seelhorster Kreuz).
Document 6: County Antrim: In ancient times, Antrim was inhabited by a Celtic people called the Darini. In the early Middle Ages, southern County Antrim was part of the Kingdom of Ulidia, ruled by the Dál Fiatach clans Keenan and MacDonlevy/McDunlavey; the north was part of Dál Riada, which stretched into what is now western Scotland over the Irish Sea. Dál Riada was ruled by the O'Lynch clan, who were vassals of the Ulidians. Besides the Ulidians and Dál Riada, there were the Dál nAraide of lower County Antrim, and the Cruthin, who were pre-Gaelic Celts and probably related to the Picts of Britain. Between the 8th and 11th centuries Antrim was exposed to the inroads of the Vikings.

Additionally, there is an urban motorway network; the radial M621 takes traffic into central Leeds from the M62 and M1. There is an Inner Ring Road with part motorway status and an Outer Ring Road. Part of the city centre is pedestrianised, and is encircled by the clockwise-only Loop Road.
Document 8: History of Ireland: By the 12th century, Ireland was divided politically into a shifting hierarchy of petty kingdoms and over-kingdoms. Power was exercised by the heads of a few regional dynasties vying against each other for supremacy over the whole island. One of these men, King Diarmait Mac Murchada of Leinster was forcibly exiled by the new High King, Ruaidri mac Tairrdelbach Ua Conchobair of the Western kingdom of Connacht. Fleeing to Aquitaine, Diarmait obtained permission from Henry II to recruit Norman knights to regain his kingdom. The first Norman knight landed in Ireland in 1167, followed by the main forces of Normans, Welsh and Flemings. Several counties were restored to the control of Diarmait, who named his son - in - law, the Norman Richard de Clare, known as Strongbow, heir to his kingdom. This troubled King Henry, who feared the establishment of a rival Norman state in Ireland. Accordingly, he resolved to establish his authority. In 1177 Prince John Lackland was made Lord of Ireland by his father Henry II of England at the Council of Oxford.
Document 9: British Isles: Hiberni (Ireland), Pictish (northern Britain) and Britons (southern Britain) tribes, all speaking Insular Celtic, inhabited the islands at the beginning of the 1st millennium AD. Much of Brittonic-controlled Britain was conquered by the Roman Empire from AD 43. The first Anglo-Saxons arrived as Roman power waned in the 5th century and eventually dominated the bulk of what is now England. Viking invasions began in the 9th century, followed by more permanent settlements and political change—particularly in England. The subsequent Norman conquest of England in 1066 and the later Angevin partial conquest of Ireland from 1169 led to the imposition of a new Norman ruling elite across much of Britain and parts of Ireland. By the Late Middle Ages, Great Britain was separated into the Kingdoms of England and Scotland, while control in Ireland fluxed between Gaelic kingdoms, Hiberno-Norman lords and the English-dominated Lordship of Ireland, soon restricted only to The Pale. The 1603 Union of the Crowns, Acts of Union 1707 and Acts of Union 1800 attempted to consolidate Britain and Ireland into a single political unit, the United Kingdom of Great Britain and Ireland, with the Isle of Man and the Channel Islands remaining as Crown Dependencies. The expansion of the British Empire and migrations following the Irish Famine and Highland Clearances resulted in the distribution of the islands' population and culture throughout the world and a rapid de-population of Ireland in the second half of the 19th century. Most of Ireland seceded from the United Kingdom after the Irish War of Independence and the subsequent Anglo-Irish Treaty (1919–1922), with six counties remaining in the UK as Northern Ireland.
Document 10: British Isles: At the time of the Roman Empire, about two thousand years ago, various tribes, which spoke Celtic dialects of the Insular Celtic group, were inhabiting the islands. The Romans expanded their civilisation to control southern Great Britain but were impeded in advancing any further, building Hadrian's Wall to mark the northern frontier of their empire in 122 AD. At that time, Ireland was populated by a people known as Hiberni, the northern third or so of Great Britain by a people known as Picts and the southern two thirds by Britons.
Document 11: British Isles: Viking invasions began in the 9th century, followed by more permanent settlements, particularly along the east coast of Ireland, the west coast of modern-day Scotland and the Isle of Man. Though the Vikings were eventually neutralised in Ireland, their influence remained in the cities of Dublin, Cork, Limerick, Waterford and Wexford. England however was slowly conquered around the turn of the first millennium AD, and eventually became a feudal possession of Denmark. The relations between the descendants of Vikings in England and counterparts in Normandy, in northern France, lay at the heart of a series of events that led to the Norman conquest of England in 1066. The remnants of the Duchy of Normandy, which conquered England, remain associated to the English Crown as the Channel Islands to this day. A century later the marriage of the future Henry II of England to Eleanor of Aquitaine created the Angevin Empire, partially under the French Crown. At the invitation of a provincial king and under the authority of Pope Adrian IV (the only Englishman to be elected pope), the Angevins invaded Ireland in 1169. Though initially intended to be kept as an independent kingdom, the failure of the Irish High King to ensure the terms of the Treaty of Windsor led Henry II, as King of England, to rule as effective monarch under the title of Lord of Ireland. This title was granted to his younger son but when Henry's heir unexpectedly died the title of King of England and Lord of Ireland became entwined in one person.
Document 12: Dunluce Upper: Dunluce Upper is a barony in County Antrim, Northern Ireland. It is bordered by six other baronies: Dunluce Lower to the north; Cary to the north-east; North East Liberties of Coleraine to the north-west; Coleraine to the west; Kilconway to the south; and Glenarm Lower to the east. Dunluce Upper also formed part of the medieval territory known as the Route.
Document 13: A8(M) motorway (Northern Ireland): The A8(M) is a motorway in County Antrim, Northern Ireland. It is 1 mile (1.6 km) long and is a spur of the M2 motorway. It was opened on 24 October 1966 and built at the same time as the M2 section to which it connects. It is part of the unsigned European routes E01 and E18.
Document 14: A6 road (Northern Ireland): The A6 road in Northern Ireland runs for 71.4 miles (114.9km) from Belfast to Derry, via County Antrim and County Londonderry. From Belfast to Randalstown the route has been superseded as a motorway (M2 and M22). Mostly single carriageway, there is a short dual carriageway section forming the Toome bypass and in Antrim town centre. In urban and suburban districts of Belfast and Derry the route is single carriageway with 4 lanes (2 lanes in each direction). In rural parts, there are numerous climbing lanes along the route. This is one of Northern Ireland's most important arterial routes, as the road runs between its two largest cities and urban areas. Between Randalstown and Derry the road forms part of European route E16.
Document 15: Lancashire: The Lancashire economy relies strongly on the M6 motorway which runs from north to south, past Lancaster and Preston. The M55 connects Preston to Blackpool and is 11.5 miles (18.3 km) long. The M65 motorway from Colne, connects Burnley, Accrington, Blackburn to Preston. The M61 from Preston via Chorley and the M66 starting 500 metres (0.3 mi) inside the county boundary near Edenfield, provide links between Lancashire and Manchester] and the trans-Pennine M62. The M58 crosses the southernmost part of the county from the M6 near Wigan to Liverpool via Skelmersdale.
