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 A8 begins at the West End of Edinburgh, in the New Town. The road originally also included Princes Street, but this stretch was declassified, as Princes Street is no longer open to all traffic.
The road continues westwards into the suburbs of the city passing Murrayfield and Corstorphine, often with an accompanying bus lane. Only once the road reaches the A720 City Bypass does it become a primary route, leading out past the Royal Highland Showground at Ingliston, and Edinburgh Airport.
At Newbridge, the A8 meets the start of the M8 and M9 motorways. From here the A8 is interrupted; it has been renumbered A89 until Bathgate, A7066 to Whitburn and then B7066 Harthill, until it resumes at Newhouse.
From Newhouse it runs parallel to the M8. Until recently there was no road of motorway standard between Newhouse and Baillieston in the eastern suburbs of Glasgow, and the A8 still carried all through traffic here, having been progressively upgraded to meet demand.  However it was finally replaced in 2017 by the last section of the M8.  It is now the principal non-motorway access between the Eurocentral business park and the settlements of Chapelhall and Calderbank, south of Airdrie.
Just prior to Junction 8 of the M8 it diverges from the motorway, and meets the A89 at Bargeddie while co-existing as the interchange for the M8 and M73. At a roundabout near Swinton it briefly merges with the A89 and heads towards central Glasgow. The A8 now passes through suburban Garrowhill, Barlanark, Wellhouse, Springboig, Cranhill and Carntyne as Edinburgh Road – much of which is a two/three-lane dual-carriageway, but an urban 30 mph (48 km/h) restriction is still applied – then past Haghill and Dennistoun as Alexandra Parade into the city centre at Glasgow Royal Infirmary and Glasgow Cathedral, where it follows the High Street and then the Saltmarket running north–south – meeting the A89 (Gallowgate) and the A749 (London Road) at Glasgow Cross. It splits for the complex one-way system, recombining prior to the junction at the start of the A814 that heads west along the Clyde, before crossing the river near The Gorbals, where it meets the end of the A74.
From there the A8 leads out of town through Tradeston, Kingston (passing under the M8's Kingston Bridge) Kinning Park, Cessnock and Ibrox as Paisley Road West, changing to Edmiston Drive past Ibrox Stadium, then through Drumoyne and Shieldhall as Shieldhall Road, Braehead as Renfrew Road and the town centre of Renfrew as Glasgow Road, Glebe Street and Inchinnan Road, passing to the rear of Glasgow Airport at Inchinnan, crossing over the M8 east of Bishopton and meeting it again at the motorway's western end, Junction 31 between Bishopton and Langbank.
The A8 becomes the primary route again and takes traffic through Port Glasgow. Its terminus is in Greenock at a large roundabout with the A78 road and the A770 to Gourock, which was the former terminus of the A8.
Three short stretches of the A8 are part of three different Euroroutes, as follows:
The A1 is the longest numbered road in the United Kingdom, at 397 miles (639 km). It connects London, the capital of England, with Edinburgh, the capital of Scotland. It passes through or near North London, Hatfield, Welwyn Garden City, Stevenage, Baldock, Letchworth Garden City, Biggleswade, St Neots, Huntingdon, Peterborough, Stamford, Grantham, Newark-on-Trent, Retford, Doncaster, York, Pontefract, Wetherby, Ripon, Darlington, Durham, Sunderland, Gateshead, Newcastle upon Tyne, Morpeth, Alnwick and Berwick-upon-Tweed.
The A6 is one of the main north–south roads in England. It runs from Luton in Bedfordshire to Carlisle in Cumbria, although it formerly started at a junction with the A1 at Barnet. It is the fourth longest numbered road in Britain; only the A1, A38 and A30 are longer.
The M8 is the busiest motorway in Scotland and one of the busiest in the United Kingdom. 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 M9 is a major motorway in Scotland. It runs from the outskirts of Edinburgh, bypassing the towns of Linlithgow, Falkirk, Grangemouth and Stirling to end at Dunblane.
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 Edinburgh City Bypass, designated as A720, is one of the most important trunk roads in Scotland. Circling around the south of Edinburgh, as the equivalent of a ring road for the coastal city, it links together the A1 towards north-east England, the A702 towards north-west England, the M8 through the Central Belt towards Glasgow, the A7 through south-east Scotland and north-west England as well as the A8 leading to the M9 for Stirling and the Queensferry Crossing.
The city of Glasgow, Scotland has a transport system encompassing air, rail, road, and an underground light metro line. Prior to 1962, the city was also served by trams. Commuters travelling into Glasgow from the neighbouring local authorities of North and South Lanarkshire, Renfrewshire, East Renfrewshire, and East and West Dunbartonshire have a major influence on travel patterns, with tens of thousands of residents commuting into the city each day. The most popular mode of transport in the city is the car, used by two thirds of people for journeys around the city.
The A43 is a primary route in the English Midlands and northern South East England, that runs from the M40 motorway near Ardley in Oxfordshire to Stamford in Lincolnshire. Through Northamptonshire it bypasses the towns of Northampton, Kettering and Corby which are the three principal destinations on the A43 route. The A43 also links to the M1 motorway.
The River Cart is a tributary of the River Clyde, Scotland, which it joins from the west roughly midway between the towns of Erskine and Renfrew and opposite the town of Clydebank.
Shieldhall is a district in the Scottish city of Glasgow. It is situated directly south of the River Clyde and is part of the wider Govan area.
The A54 road is a road in England linking Chester in Cheshire with Buxton in Derbyshire. Its route through both urban and steep rural areas presents a challenge to Cheshire County Council in maintaining the safety of the road. Many years ago it was the main east–west route in Cheshire. The importance of the A54 through Middlewich and Winsford decreased in the 1970s and 1980s with the building of the M56 motorway and dualling of the A556 at Northwich. The section through Winsford carries approximately 30,000 vehicles per day.
The Glasgow Inner Ring Road was a proposed 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, but no subsequent construction was made and the remaining plans were formally abandoned in 1980. After 30 years, a route following roughly the southern section of the proposals have also been created as the new M74.
The Glasgow and Paisley Joint Railway was the section of railway line between Glasgow Bridge Street railway station and Paisley, in the west of Scotland. It was constructed and operated jointly by two competing railway companies as the stem of their lines to Greenock and Ayr respectively, and it opened in 1840. The Joint Committee, which controlled the line, built a branch to Govan and later to Cessnock Dock, and then Prince's Dock.
The A516 road is a road in Derbyshire that runs from the A50 Junction 5, to the A601 in Derby. The road is used mostly for traffic flowing from the A50 to the A38.
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 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.
The A727 road in Scotland runs from East Kilbride in South Lanarkshire, through East Renfrewshire, to Junction 3 of the M77 motorway in Glasgow.
The A749 road in Scotland connects East Kilbride with Glasgow city centre via Rutherglen and Bridgeton.
