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.
In Great Britain, there is a numbering scheme used to classify and identify all roads. Each road is given a single letter and a subsequent number. 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.
The A8 is a major road in Scotland, connecting Edinburgh to Greenock via Glasgow. Its importance diminished following the construction of the M8 motorway which also covers the route between Edinburgh and Glasgow.
The M8 is the busiest motorway in Scotland. It connects the country's two largest cities, Glasgow and Edinburgh, and serves other large communities including Airdrie, Coatbridge, Greenock, Livingston and Paisley. The motorway is 60 miles (97 km) long. A major construction project to build the final section between Newhouse and Baillieston was completed on 30 April 2017. The motorway has one service station, Heart of Scotland Services, previously named Harthill due to its proximity to the village.
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 M90 is a motorway in Scotland. It runs from Junction 1A of the M9 motorway, south of the Queensferry Crossing, to Perth. It is the northernmost motorway in the United Kingdom. The northern point goes to the western suburbs of Perth at Broxden. A small part of the M90 was originally numbered as the M85 motorway.
The M73 is a motorway in Glasgow and North Lanarkshire, Scotland. It is 7 miles (11 km) long and connects the M74 motorway with the M80 motorway, providing an eastern bypass for Glasgow. The short stretch between junctions 1 and 2 is part of unsigned international E-road network E05, where it continues along the M8 through Glasgow. To the south, the M74 motorway is also part of the E05.
The M77 motorway is a motorway in Scotland. It begins in Glasgow at the M8 motorway at Kinning Park, and terminates near Kilmarnock at Fenwick, becoming the A77 dual carriageway. Changes were made in 2005 segregating a lane on the M8 motorway almost as far as the Kingston Bridge, which in January 2006 was extended further onto the bridge itself. It forms the most northerly part of the A77 trunk road which links Glasgow to Stranraer in the South West of Scotland.
The M80 is a motorway in Scotland's central belt, running between Glasgow and Stirling via Cumbernauld and Denny and linking the M8, M73 and M9 motorways. Following completion in 2011, the motorway is 25 miles (40 km) long. Despite being only a two lane motorway, parts of the M80 Stepps Bypass are used by around 60,000 vehicles per day.
The A80 is a road in Scotland, running from the A8 to Moodiesburn, north east of Glasgow. Prior to the M80 opening, the A80 was one of Scotland's busiest trunk roads.
The M898 motorway is a 1-mile-long (1.6 km) motorway in Renfrewshire, Scotland. It is a spur route from the M8 motorway towards the Erskine Bridge. It lacks hard shoulders along its length. Its northern terminus comes at the junction with the A726 road, the former location of the toll booths for the Erskine Bridge, which were removed on 1 April 2006.
The A728 is a route number in Glasgow, Scotland applied to two connected roads.
The Glasgow Inner Ring Road is a partially completed ring road encircling the city centre of Glasgow, Scotland. Construction of the roads began in 1965, and half of its circumference was completed by 1972 - forming part of the wider M8 motorway, but no further construction was made and the remaining plans were formally abandoned in 1980.
The A725 road in Scotland is a major route which is a trunk road dual carriageway for almost its whole length, connecting several of the large towns of North Lanarkshire and South Lanarkshire, linking the M8 and M74 motorways; it has been upgraded frequently since its construction, with the most recent major work completed in 2017. In combination with the A726 road which meets the M77 motorway, it forms a southern and eastern bypass for the city of Glasgow.
The A726 road in Scotland is a major route with several distinct sections with different characteristics and names; owing to its stages of construction, since 2005 it has two separate parts, the first running between Strathaven in South Lanarkshire and Junction 5 of the M77 motorway south of Newton Mearns in East Renfrewshire via East Kilbride, and the other running between Junction 3 of the M77 and the M898 motorway near the Erskine Bridge, via Paisley and Junction 29 of the M8 motorway near Glasgow International Airport.
The A730 road in Scotland runs between the centre of Glasgow and the south-eastern edge of the city's urban area at Cathkin.
The A89 is a trunk road in Scotland, United Kingdom. It runs from High Street, Glasgow to Newbridge in Edinburgh. It was once the A8, which has now been replaced, mostly by the M8.
Tannochside is a settlement approximately 8 miles (13 km) south-east of Glasgow, Scotland. Although historically considered part of Uddingston, it lies within a separate local authority area: Tannochside is contained within the boundaries of North Lanarkshire council, whereas the original village of Uddingston is in South Lanarkshire.
European route E1 is a series of roads in Europe, part of the United Nations International E-road network, running from Larne, Northern Ireland to Seville, Spain. There is a sea crossing between Rosslare Harbour, in Ireland, and Ferrol, but no ferry service. The road also passes through Portugal – past the city of Porto, through the capital, Lisbon, and then south to the Algarve, passing Faro before reaching the Spanish border west of Huelva.
The A8 in Northern Ireland is a 26.1 km route connecting the city of Belfast with the harbour town of Larne. One of the busiest routes in the region, the road forms part of the unsigned European routes E01 and E18.
